海外TECH	DEV Community	Incident Response for AWS MySQL	https://dev.to/giladmaayan/incident-response-for-aws-mysql-32l6	Incident Response for AWS MySQL What is AWS MySQL AWS supports MySQL in various ways including the fully managed Amazon Relational Database Service Amazon RDS It simplifies configuration operation and scaling tasks allowing you to easily operate a relational database like MySQL in the AWS cloud Amazon RDS supports DB instances that run several versions of MySQL It provides flexible capacity for your database and can help manage common database administration tasks Once you create an Amazon RDS for MySQL DB instance you can perform various tasks including Resize your DB instance Authorize connections to your DB instance Create Multi AZ secondaries and read replicas Restore data from snapshots and backups Monitor your DB instance s performance Use MySQL apps and utilities to access and store the DB instance s data What Is AWS Systems Manager Incident Manager Incident Manager is a feature of AWS Systems Manager that provides an incident response and management console AWS Systems Manager helps you centralize operational data from various AWS services and automate tasks across AWS resources What is AWS Systems Manager AWS Systems Manager lets you create logical groups of resources for example applications application stack layers production and development It allows you to choose a resource group and then view various related metrics including Recent API activityRelated notificationsResource configuration changesOperational alertsSoftware inventoryPatch compliance statusAWS Systems Manager provides a centralized console to view and manage AWS resources You can take action according to the specific operational needs of each resource group This tool aims to provide you with comprehensive visibility and control over resources What is Incident Manager Incident Manager provides an incident management console for mitigating and recovering from incidents affecting applications hosted in the AWS cloud An incident can be an unplanned interruption to services or an unexpected reduction in quality You can use AWS tools to extend the capabilities of Incident Manager For example adding CloudWatch alarms and metrics AWS Chatbot and AWS CloudTrail to facilitate rapid incident response You can create and automate response plans and let Amazon EventBridge events or CloudWatch alarms initiate them Incident Manager lets you define runbooks and then use AWS Systems Manager automation to automate critical responses These runbooks also provide detailed steps to first responders Using various contact methods Incident Manager can automatically engage the relevant stakeholders for each incident Incident Manager can automatically escalate through responders to ensure visibility and active participation during each incident and employ an AWS Chatbot client to ensure incident responders actively respond to incidents It also provides incident tracking features letting responders review incident details follow runbooks and create and remediate follow up items Securing Amazon RDSAmazon offers various features you can use to manage information security for AWS RDS resources and databases hosted on RDS instances Depending on the type of task users need to perform with RDS you can use any of the following access management methods Network access controlーyou can achieve the greatest network access control by running a DB instance within a virtual private cloud VPC via the Amazon VPC service User access controlーAWS Identity and Access Management IAM policies enable you to assign permissions that allow only specific users to manage RDS resources Resource management privileges include creating describing modifying and deleting DB instances modifying security groups and tagging resources DB instance access controlーsecurity groups can help you restrict connectivity to databases on a DB instance only to specific IP addresses and EC instances Secure protocolsーyou can establish secure connections with DB instances running MySQL databases through Transport Layer Security TLS or Secure Socket Layer SSL protocols Data encryptionーRDS encryption enables you to secure DB instances and snapshots at rest It encrypts the data on the hosting server using the industry standard AES encryption algorithm AWS Systems Manager Incident LifecycleAWS Systems Manager Incident Manager is an incident lifecycle management tool which lets you recover AWS hosted applications from a cyber attack as quickly as possible It provides tools and best practices for every stage of the event lifecycleAlerting and EngagementIncident Manager supports the alerting and engagement phases of incident response by generating alerts about events in your application This step starts before any event is detected and requires a deep understanding of the application You can use Amazon CloudWatch metrics to monitor data about application performance that might indicate a cyber attack TriageWhen an alert comes in first responders need to determine its potential impact Incident Manager lets you classify an incident into five levels of impact Critical impactーcomplete application failure that significantly affects all customers Partial application failureーincident impacting many customersModerate impactーincident that results in reduced service to customersLow impactーincident that is felt by customers but has minimal impactNo impactーincident that does not currently affect customers but urgent action is required to avoid impact Investigation and MitigationIncident Manager provides an incident details view that provides the following capabilities Runbooksーthese are automated processes that can investigate the incident automatically discover data or try common solutions The playbook also provides clear repeatable steps to help the team mitigate this type of incident Timelineーshows the actions taken both automated and manual Each intervention by the team is automatically recorded with a timestamp and automatically generates details Metrics ーdisplays automatically selected metrics and metrics manually added by the team This provides important information about application activity during an event Chatーyou can use chat channels to interact with events directly through AWS chatbots AWS Chatbot lets you use Incident Manager API operations in automated chat channels You can resolve the incident directly from the chat channel from any device Post incident AnalysisAfter the event is over Incident Manager enables post incident analysis This provides a structure for teams to develop new response methods and improve their process In this part of the process Incident Manager helps teams discover and implement the following optimizations Changes needed to applications related to the eventーhardening applications and improving fault tolerance Incident response plan changesーincorporating lessons learned over time Changes to runbooksーchanging the steps needed to address a specific type of cyber incident Changes to alertingーafter an incident the team may have discovered an important metric or threshold that can be used to alert to an incident earlier ConclusionIn this article I explained the basics of hosted MySQL on AWS via the Relational Database Service RDS and showed how to manage incident response for MySQL using the AWS Systems Manager Incident Manager feature I hope this will be useful as you improve the security posture of your cloud hosted databases in AWS	2022-04-14

Annie Spratt on UnsplashIn the last couple of years the number of developers contributing to Open Source has grown exponentially The Github team deserves all praise The Developer Experience is much better than what it used to be They are lowering the entry barrier for new developers to come and contribute to Open Source Let s go through some great tools introduced and some amazing changes around GitHub which improved the Developer Experience and made GitHub an undisputed leader ToolsLet s go through the tools introduced in the past few years CodespacesOne of the biggest problems developers face is setting up the development environment As someone contributing to multiple Open Source projects it s a pain and I am sure many of you will agree with this GitHub came up with Codespaces You setup the development environment in a single click it s amazing isn t it And can use it online too press and it spins up your environment on the cloud Many Open Source developers have access to use it for free For enterprises you need to pay to use it and the pricing is much cheaper than buying a high end laptop GitHub ActionsAfter NodeJS this is the best thing Developer Community got Before GitHub Actions it was a pain to setup the CI CD and everyone especially Open Source maintainers knows this With GitHub Actions you can setup CI CD for your project with ease and even you don t need to leave the github com With so many Actions created by the community you can setup your essential CI CD within a few minutes So what are you waiting for Go ahead and utilize this feature and you can publish your Actions on marketplace Code SearchSearching code on GitHub was a pain it was slow confusing and sometimes we used to get results we were not looking for GitHub launched GitHub Code Search which makes code search faster and more accurate you can select which repo you want to search code for You get a lot of filters for the correct code CopilotI am sure you already know what Copilot is and what it can do for you I still get amazed by what it can sometimes do I write a single character and press the tab and it writes the exact code that I am thinking even better Many developers got the access and are enjoying it and it has improved my productivity for sure Also try Copilot for writing blog posts you will be surprised GitHub CLINo I am not talking about Git which we use GitHub decided to release its CLI because why not This is the era of CLI You can open a PR see a PR status see all issues etc You can download it from here GitHub SponsorsNot a tool but a fantastic addition to the ecosystem funding for Open Source is a tricky topic Many large enterprises use them but don t care to support them GitHub sponsors are trying to fill that gap so organizations and developers know what projects they rely on and choose to sponsor projects or open source contributors With GitHub Sponsors developers keep the entire money as GitHub does not charge any fee You can get more details here GitHub Mobile AppWhat if you are traveling and there is an emergency and you need to review and merge PR GitHub mobile app has matured over the year and is available for both Android and Apple phones It has most of the features you need to review merge and read the code Download if from here Github com Dark themeEveryone I know was rooting for this feature GitHub finally launched a dark theme We have multiple themes to choose from you can also sync them with the system setting Fetch UpstreamKeeping a fork in sync with the remote branch was always a pain With this feature GitHub just solved an immense pain for s of contributors on GitHub Projects Beta Everyone using GitHub relies on other tools like Jira and Azure DevOps for project management For enterprises it is easy to pay for a project management tool For open source maintainers not so much they rely on GitHub issues With Projects they will be able to plan in a better way DiscussionsIf you are Open Source maintainers you know how much pain it was to manage questions and RFCs using GitHub issues Open Source maintainers pushed developers to use StackOverflow but was it the best choice Open Source projects miss so much valuable content available somewhere else In case some question on SO leads to a new Bug or a feature Discussions are the best place to have QnA and RFCs and it allows to convert Discussion to issues as well It means all information is available in the repository Also maintainers know who is helping the project more by getting involved in QnA To enable Discussions for the repository Go to Settings and you will find the below option ListI am sure like me many of you star a lot of repositories on GitHub But do you remember why you starred those repositories or which one you starred once you have starred many of them I don t so I was pleased when List was introduced You can add a starred repository to an existing list or create a new List so you remember why you starred the repo Special RepositoryGitHub has a special repository Create a repository with the same name as your username to use it You can use this repository to customize your GitHub profile you can visit my profile to see an example Also if you want to customize yours don t miss this free course By Eddie Update PR with remote BranchAnother big pain while doing PRs was what if your PR takes some time to merge and the master is already ahead Of course you update your branch with the main branch and you have to do it manually which wastes the developer s time GitHub came up with an option to update your PR with a single button click thus saving a lot of time for developers Command Palette Feature Preview Want to navigate through GitHub quickly Use the new Command Palette To open the command palette use the below keys macOS ⌘k or ⌘opt kother Ctrl k or Ctrl alt kThis feature is not enabled for everyone Go to the Feature Preview tab to see if you have access to this feature Pull Request File Tree Feature Preview It is difficult to find and review a file when you change many files within a PR Sometimes the file is at the bottom of the screen and reviewers have to scroll to see the files With this feature we get the files changed within the review tab and it s easy to navigate and look for changes in a file GitHub ReleasesCreating a release note is essential It tells the users of your projects product what the changes introduced in the new release are Open Source maintainers have used different approaches for years Thanks to GitHub releases you can do it from the repository itself Once you draft a new release you can choose your tag name against which branch you want to draft the release and it will pick up all the issues included in the new release Example Code NavigationI read Open Source code to understand what they do and sometimes the reference to some functions is in another file Before the code navigation feature landed on GitHub the only way was to go to that file and read It was time consuming with code navigation it s easy to move to another file where the code exists Community Initiative Stars ProgramIn GitHub launched the GitHub stars Program to recognize the developers educating and inspiring the developers across the globe Unlike most programs this Program is unique as developers worldwide can nominate you The perk of being one of the stars you get to give early feedback for new features and interact with a fantastic team Also no one can beat the GitHub in swag and I have almost my entire streaming setup given by GitHub It supports you as well so you can continue your community effort ConclusionThese are a few tools and features there are many I recently found I can follow organizations on GitHub now GitHub is pushing a lot of great features Let me know which one is your favorite and I know it isn t easy to choose Shoutout to my GitHub sponsors for supporting my work	2022-04-14 11:25:47

海外TECH	DEV Community	Cloud computing – everything you need to know	https://dev.to/firdavs_kasymov/cloud-computing-everything-you-need-to-know-31ld	Cloud computing everything you need to knowCloud computing is one of the most popular buzzwords amongst technology enthusiasts and professionals It is a revolutionary technology that has changed how applications are built deployed and used I m pretty sure everyone reading this article has used an app or service that takes advantage of cloud computing technology Despite being a popular topic not so many people understand the fundamentals of cloud computing and how significant this technology is to this era where we rely on computers to do almost everything In this article we will discuss all the basics of cloud computing including the cloud computing providers and how different categories of users can take full advantage of this technology Let s dive in What is cloud computing In simple terms cloud computing refers to the delivery of computing services including server hardware storage networking analytics software and databases over the internet Back in the days before cloud computing organizations used to rely on their local servers to host their in house applications and storage of data Cloud computing has changed all this companies no longer have to spend thousands or even millions of dollars building local computing infrastructure They can simply rent computing resources and storage they need from any of the cloud computing providers including Amazon Web Services AWS Microsoft Azure Google Cloud Alibaba Cloud and many more AWS is still the most popular cloud computing service provider with a market share of over For the most of this article AWS will be our major focus since it is the most popular option and the one with the most services Source Cloud computing services delivery models Infrastructure as a Service IaaS This is a cloud computing delivery model where providers such as AWS Microsoft Azure and Google Cloud offer users computing resources storage and application programming interfaces APIs that they can use for their various workloads AWS has a wide range of services that users can choose from based on their computing and storage needs Some of the most of most used ones include Elastic Computer Cloud EC for computing and Amazon Simple Storage Service Amazon S for storage With these services users pay for what they need For instance EC gives you the option to choose the number of CPU cores and the amount of RAM you need for your application AWS has more than services that developers and other professionals can choose from to get their work done Platform as a Service PaaS PaaS is a cloud computing delivery model where the service providers host software development tools on their servers These tools are mainly used for building and testing applications before they are deployed on the web for final consumers to use Some of the popular PaaS platforms include Google App Engine AWS Elastic Beanstalk and Salesforce s Lightning Platform These platforms provide all the tools that developers need in their app development cycle Many of these PaaS platforms also host the software after it is developed However a developer can choose to host their software on another platform of their choice Software as a Service SaaS This refers to a cloud computing delivery model where providers deliver software applications via the internet The target market for SaaS applications are final consumers SaaS applications can be accessed by anyone via their mobile device or computer Some of the popular SaaS platforms include Google WorkSpace Microsoft HubSpot Salesforce Shopify and many more Benefits of using cloud computing services like AWS Cost effectiveCost is one of the reasons organizations are shifting from local computing to cloud computing With cloud computing companies pay for the specific resources they need Services such as Amazon s EC give users the option to pay based on the exact computing resources they are using That means costs only go up when your application is being used the most It is much easier to scale upCloud computing service providers like AWS allow you to get more resources for your application with just a few clicks You also have the option of automating this process Scaling up with local computing requires procuring and configuring new servers which is time consuming and costly Deploying apps in different regionsApplications deployed on a server that is geographically closer to you run faster than those deployed further away AWS has computing infrastructure in up to geographical regions spread out across all the five continents including North America South America Africa Asia Europe and Australia So developers can deploy their apps in regions where they expect most of their users to be located Unlimited storage capacityNo matter how much space you need cloud services like Amazon s S got you covered As we shared earlier you have the option of paying for the exact kind of space you need So you can always increase the size based on your storage demands Data securityAWS and other cloud computing providers spend billions of dollars on the security of their platforms So if you deploy your app on any of the top rated platforms you will be assured of top notch security Final thoughtsCloud computing is one of those fundamental technologies that is affecting almost everyone in a certain way Enterprises and businesses now rely on IaaS platforms to deploy apps without having to incur the huge costs of buying and maintaining servers On the other hand developers and other professionals are using PaaS platforms to build test and deploy apps And finally final consumers now use SaaS applications to do power demanding tasks like photo editing without necessarily having to buy expensive and powerful computers As long as you are using the internet you will at some use a cloud computing service	2022-04-14 11:20:22

frontends A path to evolve legacy codebasesMicro frontends are the present and the future for scaling large client side applications Why should you implement this architectural style Let s dig into the reasons that led me and my team to adopt it Working at scale is one of the main goals of modern software engineering Micro frontends is an architectural style and a technique many organizations are adopting to address this problem Generally speaking the motivations for using this approach are basically the same that makes us choose micro services in the “backend world breaking down a monolithic codebase into micro apps each of which developed by autonomous team responsible for the entire lifecycle of this portion of the project This approach has the main benefits of improving the development process and the developer experience because each team is focused on a smaller scope and it can independently deploy new features adapting to changes with a high velocity In other words micro frontends inherit microservices well known benefits such as development agility technological freedom and targeted deployments We pay for this high encapsulation of business rules and this high flexibility for each team with an increased effort for infrastructure since automation is one of the key requirements for a successful implementation Modern cloud technologies greatly simplify this work and can be considered the enabling technologies for this architectural style Despite this a distributed system is intrinsically more complex than a monolithic one because we must take in consideration aspects such as orchestration distributed failures observability and automated deployments Objectives amp PrinciplesFor the purpose of the article we can consider our initial architecture as a classic client server application where the PHP server is responsible for generating HTML pages and JavaScript client side code is responsible for making these pages interactive We need to evolve the user experience making the user interface more responsive and more app like We also need to improve the developer experience because maintaining this legacy codebase has become overwhelming and the team was not so fast to adapt to ever evolving requirements The final objective of this architecture migration is to improve the user experience modernize the user interface and speed up the development process and we would achieve this purpose satisfying the following objectives Independent artifacts team should be able to independently deploy their frontend applications with minimal impact to other services Other teams should consider other micro frontends more or less like a black box Easier maintenance each micro frontend module should be developed in isolation and the developer has lower cognitive load when developing a feature or debugging Each micro frontend has a separate and decoupled codebase from the others and each of them represents a business subdomain For this reason it s easier for a developer to become a sub domain expert Autonomous teams each team should be responsible for making the right choices for its module Technology independence the legacy framework and tooling should coexist with modern technologies allowing to evolve the codebase without struggling Scalable development  each micro frontends should be independent from each other so each team could deploy at its own pace increasing the development speed ChallengesAs it often happens in software engineering every choice comes at a cost or at least with some aspects to take into consideration Choosing a micro frontends architecture requires facing these challenges Parent child integration The micro frontend architecture involves loading different modules to compose the UI of an application This requires defining the communication modalities between the loaded micro frontends that guarantee the performance the consistency of the user experience that is expected from a monolithic application and at the same time the low coupling between the modules Many of the implementation strategies involve creating an app shell that acts as an orchestrator of the micro frontends Operational complexity A micro frontend application involves creating and managing separate infrastructure for all teams Automation is a critical aspect of the implementation to ensure scalability of the system Consistent user experience Child applications should use the same design system of the parent application This could be particularly difficult when evolving a legacy application because sharing the same UI components and CSS libraries is not an option ImplementationFirst of all let s briefly describe the application domain which is useful to understand our choices Nuvola is a web application that offers a range of services that fully cover the needs of schools from teaching to administration Teachers use the software for teaching management insert lesson topics assignments grades absences etc Instead the primary purpose for parents and pupils is to read the data entered by the teachers Finally the school secretariat uses it to fulfill administrative burdens registration of documents communications personnel management etc The core concept is to apply a Strangler Pattern in order to gradually eliminate the original application by replacing each sub domain with a micro frontend Adopting the Pattern in combination with a micro frontends architecture can enable the frontend team to independently deploy each application module and increase the parallelism of development We followed the Micro frontends Decision Framework as a guide for top level architectural choices This is a super short summary of our decisions Definition vertical split Every page displays a single micro frontend and there s an orchestration layer responsible for switching micro frontends We identified a subdomain with a type of user so each micro frontend is a micro app serving a single type of user Composition client side A tiny layer of JavaScript code is responsible for loading micro frontends on the page In our architecture switching between micro frontends is a residual use case because it can happen only for users with different roles like both teacher and parent in the same school Routing client side Since we compose micro frontends client side delegating the routing responsibility to the same JavaScript code is the go to choice Communication local storage Previous choices aim to enforce encapsulation and minimize the need for communication between micro frontends so the only thing we need to share is authentication In future developments if the modules need to share something more we will likely rely on a loose communication system such as an event emitter We chose to attach parent and child using a run time integration via javascript because it s one of the most flexible ways to do that Each micro frontend exposes an entry point and a rendering function The app shell knows the list of entry points of the available micro frontends and is responsible for loading them on the page lt html gt lt head gt lt title gt Parent application lt title gt lt head gt lt body gt lt script gt const microFrontendEntries pupils area teachers area administrative area const microFrontendScript document createElement script microFrontendScript src microFrontendEntries window location pathname document body appendChild microFrontendScript lt script gt lt body gt lt html gt This example is a basic implementation of the app shell Once the micro frontend is loaded on the page it renders the corresponding content In our configuration the app shell does not render anything it s only responsibility is to load and orchestrate micro frontends Full disclosure at the time of writing each micro frontend is served by separate HTML pages and the server is responsible for redirecting the user to the corresponding micro frontend HTML Future release will adopt the implementation described previously Deployment pipelineAWS CodePipeline orchestrates the pipeline steps A new commit is pushed to the repository main branch triggering the deployment AWS CodeBuild clones the latest version of the code from the repository and runs the build commands that install dependencies transpile and minify code The build step produces static assets JS SVG CSS HTML files Build output is transferred to an S bucket AWS CloudFront serves static assets to the parent application A side note on assets cachingA popular performance optimization technique for serving static assets is to set a long cache expiration time and generate dynamic file names by including the content hash When connecting micro frontends together their entrypoint must be stable and can t be dynamically generated with the content hash algorithm So the solution we adopted is to generate a manifest file which maps the micro frontend name with the dynamic name of the entry point The manifest file must never be cached or at most it can be saved in a shared cache CDN that we can invalidate at each deployment Cache is configured on our S origin setting Cache Control header appropriately Manifest file Cache Control max age s max age month on sharedAll other assets Cache Control max age year Webpack Module FederationOn Webpack was released We are already distributing our first version of the micro frontends solution based on the code previously presented However This release is shipped with the Module Federation plugin which abstracts the parent child integration in a very effective way Being a Wepack plugin we just upgraded Webpack to version and we were ready to use it Put it simply  Module Federation allows to assign to each module the role of host or remote Remote modules can be considered independent and expose one or more entry points Host modules are containers that know entry points of remote modules and can therefore use them There s a lot more things going on but this is the core concept For instance Module Federation allows each module to be both remote and host at the same time or can handle shared libraries avoiding the user downloading shared libraries multiple times when it is a dependency of many micro frontends on the page Here s an example of configuration for a remote module const ModuleFederationPlugin require webpack containerconst deps require package json dependenciesmodule exports plugins new ModuleFederationPlugin name RemoteApp filename remoteEntry js exposes renderMFE src index shared react requiredVersion deps react singleton true react dom singleton true requiredVersion deps react dom This configuration declares a remote entry for a module called RemoteApp that exposes a renderMFE function Moreover it declares two shared libraries react and react dom It could seem counterproductive to share something between micro frontends instead avoiding a multi framework approach keeps the project more cohesive and more maintainable However we know this is a very valuable possibility because we probably need it during further steps of migration to allow the coexistence of jQuery and React for the small period of time we need to completely migrate our codebase What s next At the time of writing this article we have completed the migration of the parents and pupils area and we have noticed an increase in the use of this section by our users This for us means that the update has been well received and has fixed at least some of the usability issues that made it less user friendly Secondly we have seen a relative reduction in the cost of our cloud architecture due to adopting the API model compared to generating HTML on our main servers Infrastructure costs have grown in absolute terms due to two factors Our user base is constantly growing more and more schools are choosing to use Nuvola as a management software and as an electronic register The advent of the COVID pandemic has generated greater use of our software which has represented the official software solution for communicating with schools during the distance learning period Given the excellent results obtained we are already working on the migration of the other parts of the software using the same principles already implemented Surely Webpack Module Federation will play a key role in this process and will be used for an even simpler and more immediate orchestration Grazie per aver letto fino a questo momento condivideròmaggiori dettagli del nostro percorso in post futuri Continuate a seguirci nel nostro blog By Mirco

海外TECH	DEV Community	How to Add Customer Profile to Your Next.js Ecommerce Store	https://dev.to/medusajs/how-to-add-customer-profile-to-your-nextjs-ecommerce-store-26dp	How to Add Customer Profile to Your Next js Ecommerce StoreMedusa is an open source headless commerce platform that aims to provide developers with a great developer experience Although it provides Next js and Gatsby storefronts to use you can also use any storefront of your choice To make your developer experience even easier Medusa provides a client NPM package that you can use with JavaScript and Typescript frameworks In this tutorial you ll learn how to install and use the Medusa JS Client in your storefront to implement a customer sign up and profile flow You can find the code for this tutorial in this GitHub repository PrerequisitesThis tutorial assumes you already have a Medusa server installed If not please follow along the quickstart guide Furthermore this tutorial uses the Next js starter to implement the customer profile However the tutorial will focus on how to use the Medusa JS Client in particular So you can still follow along if you are using a different framework for your storefront Install the Medusa JS ClientIn your storefront project s directory install the Medusa JS client if you don t have it installed already npm install medusajs medusa jsIf you re using our Next js or Gatsby starters then you don t need to install it Initialize ClientIn the Next js starter the client is initialized in utils client js and you can just import it into your components However if you re using your custom storefront here s how you can initialize the Medusa client const client new Medusa baseUrl BACKEND URL Where BACKEND URL is the URL to your Medusa server You can then use the methods and resources in the client to send all types of requests to your Medusa server which you ll see later in this tutorial Add StylesThis step is optional and can be skipped To add some styling for the rest of the tutorial you can create the file styles customer module css with this content Add Customer to ContextIn the Next js starter the StoreContext holds all variables and methods important to the store like the cart object In this section you ll add a variable and a method to the context customer and setCustomer respectively In the defaultStoreContext variable in context store context js add the following export const defaultStoreContext customer null setCustomer async gt Then in the reducer function add a case for the setCustomer action case setCustomer return state customer action payload Inside the StoreProvider function add inside the useEffect under the cart initialization the following to retrieve the customer if they are logged in and set it in the context try to retrieve customerclient auth getSession then customer gt setCustomer customer catch e gt setCustomer null Notice here that you re using client auth getSession client has been initialized earlier in the file so if you re implementing this in your own storefront you d need to initialize it before this code snippet Then you use auth getSession which allows you to retrieve the current logged in customer if there is any If the customer is logged in and is returned in the response you set it in the context otherwise you set the customer to null Then add a new function inside StoreProvider to handle setting the customer const setCustomer customer gt dispatch type setCustomer payload customer This will just dispatch the action to the reducer which will set the customer object in the context Finally add the setCustomer function to the value prop of StoreContext Provider returned in StoreProvider return lt StoreContext Provider value setCustomer gt children lt StoreContext Provider gt Create Sign Up and Sign In PagesIn this section you ll create the sign up and sign in pages to allow the customer to either create an account or log in with an existing one Sign Up PageCreate the file pages sign up js with the following content import as Yup from yup import useContext useEffect useRef from react import StoreContext from context store context import createClient from utils client

className styles inputContainer gt lt button type submit className styles btn ref buttonRef gt Sign Up lt button gt lt div gt lt form gt lt main gt lt div gt In this page you use Formik and Yup to create and validate the form This form has fields email first name last name and password These fields are required to sign up a customer in Medusa The important bit here is the part that uses the Medusa client in the onSubmit function passed to useFormik const client createClient client customers create email values email first name values first name last name values last name password values password then customer gt setCustomer customer You first initialize the Medusa client You use the utility function in utils client js to do that but if you don t have that in your storefront you can replace it with the initialization mentioned earlier in the tutorial Then you use client customers create which will send a request to the create customer endpoint This endpoint requires the email first name last name and password fields If the sign up is successful the customer object will be returned and a session token will be saved in the cookies to keep the user logged in You use the customer object to set the customer in the context Notice also that at the beginning of the component you check if the customer is already logged in and redirect them to the home page in that case useEffect gt if customer router push customer router Sign In PageNext create the file pages sign in js with the following content import as Yup from yup import useContext useEffect useRef from react

createClient client auth authenticate email values email password values password then customer gt setCustomer customer Just like before you start by initializing the Medusa client Then you authenticate the customer using client auth authenticate which calls the Authenticate Customer endpoint This endpoint requires parameters email and password If successful a customer object is returned which you use to set the customer in the store context using setCustomer A cookie will also be set to maintain the login session for the customer Add Links to Navigation BarFinally in components layout nav bar jsx initialize the customer from the StoreContext const cart customer useContext StoreContext Then in the returned JSX add the following to add a link to the new pages customer amp amp lt Link href sign up gt Sign Up lt Link gt customer amp amp lt Link href sign in gt Sign In lt Link gt customer amp amp lt Link href customer gt Profile lt Link gt Notice that you also add a link to the customer profile which you ll implement in the next section Test it OutMake sure that the Medusa server is running first Then run the server for your storefront npm run devIf you open localhost now you ll see that there are new links in the navigation bar for sign up and sign in You can try clicking on Sign Up and registering as a new user Or click Sign In and log in as an existing user Once you re logged in you should be redirected back to the home page and you should see a Profile link in the navigation bar Add Customer ProfileThe customer profile will have pages Edit customer info view orders and view addresses Create Profile LayoutYou ll start by creating a layout that all profile pages will use Create components layout profile jsx with the following content import useContext useEffect from react import Link from next link import StoreContext from context store context import styles from styles customer module css import useRouter from next router export default function Profile children activeLink const router useRouter const customer useContext StoreContext useEffect gt if customer router push customer router return lt div className styles container gt lt main

className styles btn ref buttonRef gt Save lt button gt lt div gt lt form gt lt Profile gt This is very similar to the sign up form You use Formik and Yup to create and validate the form The form has inputs email first name last name and password which is optional The important bit here is the part in the onSubmit function passed to useFormik const client createClient if values password delete values password client customers update values then customer gt setCustomer customer alert Account updated successfully buttonRef current disabled false Just like you ve done before you start by initializing the Medusa client Then if the password is not set you remove it from the list of values since you ll be passing it to the server as is You should only pass the password if the customer wants to change it To update the customer info you can use client customers update which sends a request to the Update Customer endpoint This endpoint accepts a few optional parameters including email last name first name and password If the customer info is updated successfully a customer object is returned which you use to set the updated customer in the context You also show an alert to the customer that their account is now updated If you click on the Profile link in the navigation bar now you ll see the profile page with the sidebar and the edit profile page as the first page Try updating any of the information and click Save You should then see an alert to let you know that it s been updated successfully Orders PageThe next page you ll create is an orders page which will display the customer s orders Create a new file pages customer orders js with the following content import useEffect useState from react import Link from next link import Profile from components layout profile import createClient from utils client import formatMoneyAmount from utils prices import styles from styles customer module css import useRouter from next router export default function Orders const orders setOrders useState const pages setPages useState const router useRouter const p router query p parseInt router query p useEffect gt const client createClient client customers

customer orders p p gt Next lt Link gt lt div gt lt Profile gt You first create an orders state variable which starts out as empty You also have a pages state variable to keep track of the number of pages available Then in useEffect you retrieve the orders using the Medusa client useEffect gt const client createClient client customers listOrders limit offset p then result gt setOrders result orders setPages Math ceil result count result limit p After initializing the client you retrieve the orders of the customer using client customers listOrders This method sends a request to the Retrieve Customer Orders endpoint This endpoint accepts fields limit offset fields and expand Here you just use limit and offset limit indicates how many orders should be retrieved per page and offset indicates how many orders to skip from the beginning to get the orders of the current page This request returns the list of orders as well as additional fields important for pagination including count which indicates the total count of the orders and limit which is the current limit set You set the orders state variable to the orders returned from the method and you set the number of pages based on the count and limit fields Finally you display the orders in a table showing the ID total and status You also show pagination links for “Previous and “Next if applicable for the page This is done for the simplicity of the tutorial If you open the orders page now you ll see the list of orders for your customer if they have any Addresses PageThe last page you ll create in the profile is the Addresses page which will allow the customer to see their shipping addresses Create the file pages customer addresses js with the following content import Profile from components layout profile import StoreContext from context store context import styles from styles customer module css import useContext from react export default function Addresses const customer useContext StoreContext return lt Profile activeLink addresses gt lt h gt Addresses lt h gt customer amp amp customer shipping addresses length amp amp lt p gt You do not have any addresses lt p gt customer amp amp customer shipping addresses map address gt lt div key address id className styles address gt lt span gt lt b gt First Name lt b gt address first name lt span gt lt span gt lt b gt Last Name lt b gt address last name lt

gt lt span gt lt b gt City lt b gt address city lt span gt lt span gt lt b gt Country lt b gt address country lt span gt lt div gt lt Profile gt You use the shipping addresses field in the customer object stored in the context and display the addresses one after the other You can also access the billing address if the customer has any using customer billing address If you go to the Addresses page now you ll see the customer s shipping addresses listed What s NextUsing the Medusa JS Client you can easily interact with the APIs to create an even better customer experience in your storefront This tutorial did not cover all the aspects of a profile for simplicity Here s what else you can implement View Single Orders You can use the orders object you already retrieved on the orders page to show the information of a single order or you can use the Retrieve Order endpoint which is accessible in the client under client orders retrieve Address Management You can use the Update Shipping Address endpoint accessible in the client under client customers addresses updateAddress you can use the Add Shipping Address endpoint which is accessible in the client under client customers addresses addAddress and you can use the Delete Shipping Address endpoint which is accessible in the client under client customers addresses deleteAddress Saved Payment Methods You can retrieve the saved payment methods if you use a payment provider that supports saving payment methods like Stripe using the Retrieve Saved Payment Methods endpoint accessible in the client under client customers paymentMethods list Reset Password You can add reset password functionality using the Create Reset Password Token endpoint accessible in the client under client customers generatePasswordToken then you can reset the password using the Reset Customer Password endpoint accessible in the client under client customers resetPassword You can check out the API documentation for a full list of endpoints

海外TECH	DEV Community	Is it really worth it to spend time reading e-books?	https://dev.to/noraclarck1993/is-it-really-worth-it-to-spend-time-reading-e-books-1ig7	Is it really worth it to spend time reading e books The contrast between ebooks and paper books might take hours to debate However as we move towards a digital world everyone must stay up to the trends and adapt The number of individuals who read books steadily decreases as more people get interested in technology Publishing is one industry that has transitioned to digital to serve readers better Because ebooks have so many advantages they are being used by academic institutions and organizations to share information with their users If you d like to learn more about the main benefits of electronic books over printed books keep reading Hundreds of thousands of books to choose fromThe portability of ebooks is one of their most appealing features There s no need to worry about losing your favorite such as Romantic Suspense Books since they re small enough to fit in a purse or backpack One ebook may hold thousands of ebooks which will amaze you Imagine what it would have been like if you had to lift a hundred volumes There s no need to be concerned about the storage limit this way As a result students save time and energy by not lugging about as many books Simple updatesWhat happens if your instructor instructs you to use a more recent edition of the book you re supposed to be reading You go out and spend money on a new book correct On the other hand ebooks don t need to be updated all you have to do is click the update button In seconds authors and publishers may make modifications to their ebooks without contacting a publishing agency It saves money and timeEbooks were created to save readers both time and money Ebooks allow you to save both time and money by eliminating the need to purchase physical copies The days of students shelling out hundreds of dollars for books at bookshops are long gone Because of this they were forced to travel between towns and get the necessary materials With ebooks in users pockets they have instant access to anything in today s world A pleasure to look atWhen reading on an electronic device one may quickly alter screen brightness based on preference Readers that have a dark mode do not put pressure on your eyes Students easy access to a wide range of online resources is one of the most significant drawbacks of ebooks This is why parents must monitor their children s reading habits Similar to spy s parental control software some applications enable parents to update the privacy controls of ebooks Shareable materialUnlike printed books ebooks may be sent to numerous users simultaneously Ebooks include a built in social function that lets you share the material with other users One person could get a printed copy of the book but rather an ebook can be shared with several individuals at once Ebooks have made it possible for students and colleagues to communicate with their supervisors and lecturers in real time Experience of virtual and augmented realityAugmented reality has revolutionized the eBook experience D graphics on the user s screen may now be added to text and photos Readers can see a computer generated D representation of the picture which enhances the immersion of the reading experience specially if you are reading Vampire Romance ebooks To see an augmented version of a picture all the user needs to aim their smartphone at the image file This technology is being included in eBooks by several educational institutions and organizations to improve the user s experience Easily obtainable throughout the worldYou may save eBooks to your computer for later use The eBook is portable and may be read at any time There are no restrictions on where students or staff may access the training materials People on the move will appreciate its portability Even if you don t have internet connectivity you can still use specific eReaders since they provide offline access Readers may access any eBook such as Erotic Romance Ebook at any time and from any location unlike physical books that must be ordered or bought from a bookshop resulting in wasted time due to delivery or travel time Final ThoughtsIn comparison to physical books eBooks have a lot more potential As opposed to traditional print books eBooks enable readers to engage with the information The most a reader can do while working with a printed book is highlight or make notes on individual pages eBooks on the other hand provide a plethora of options including the ability to listen to the book as an audiobook or view videos as well as search for unfamiliar vocabulary eBooks already have an advantage in user engagement because of augmented reality and interactive features EBooks are more cost effective than print books for both the publisher and the end user Shortly eBooks will revolutionize the studying and educational experience but print books will always have a place in our cultural heritage	2022-04-14 11:01:30
