海外TECH	DEV Community	Easily deploy your portfolio website with AWS CDK 🚀	https://dev.to/kumo/easily-deploy-your-portfolio-website-with-aws-cdk-4l9b	Easily deploy your portfolio website with AWS CDK Why follow this tutorial Coding your own portfolio website is a cool introduction to HTML CSS and JavaScript frameworks but there is always a hurdle one I am done how do I deploy my website to the world wide web Other question how do I accomplish it using state of the art technologies and following industry standards To reach this goal I will use the AWS CDK Cloud Development Kit combined with TypeScript to provision a Infrastructure as Code CloudFront application serving my website all around the world Here is a quick look of what the architecture of the app will look like at the end I used this deployment method to deploy the website of sls mentor an open source AWS serverless audit tool I ve been working on these last months I will go step by step explaining everything I did when I achieved this Set up a TypeScript CDK project gt To use the CDK you first have to configure an AWS profile in your CLI The official documentation is very easy to follow if you need help Run these commands in your CLI to setup your CDK project mkdir portfolio amp amp cd portfolionpx cdk init language typescriptcdk init language typescript creates a base TypeScript repository with the following structure portfolio│ gitignore│cdk json│package json│package lock json│ts config json└ーbin│└ーportfolio ts└ーlib│└ーportfolio stack ts└ーnode modulesbin folder contains the different stacks of your project This is where I can set environment variables like the AWS accountId or region lib folder contains the details of my stacks I only have one and it s where I will provision all the necessary resources to deploy my static website cdk json contains the global CDK configuration For this simple use case there will be no need to modify it ️For certificate reasons my CDK application must be deployed to region us east the region is not important even if end users are not part of it as we will see To enable it add the following snippet in bin portfolio tsnew PortfolioStack app PortfolioStack To be added env region us east End To finish the CDK set up run the following command in your CLI cdk bootstrapcdk bootstrap deploys on your AWS account the necessary resources to be able to later deploy your full app Last step add the folder containing my website portfolio └ーfront│└ーsrc│└ーindex html│└ーstyles css Here I use simple HTML CSS but it can be the built files of a React or Angular project too Upload your portfolio on the AWS cloudFirst step to host my portfolio on AWS is to create a container hosting the website s files The easiest solution is to use AWS S and to provision a new bucket containing these files I need to specify the path of the base html file of my website index html It is also one of the rare cases where I need to set publicReadAccess to true because the content is public I want everyone to have access to my portfolio I have another constraint I want the content of this bucket to always contain the latest version of the website s source code CDK offers a construct named BucketDeployment that replaces the content of the bucket with the files found at a specified location front src of my repository at each deployment Added together the stack definition of PortfolioStack in the file lib portfolio stack ts should look like this export class PortfolioStack extends Stack constructor scope Construct id string props StackProps super scope id props Path of the folder containing the built website const FRONT SRC PATH path join dirname front src Create the bucket hosting the website const staticWebsiteHostingBucket new Bucket this StaticWebsiteHostingBucket publicReadAccess true websiteIndexDocument index html Sync the bucket s content with the codebase new BucketDeployment this StaticWebsiteHostingBucketSync sources Source asset FRONT SRC PATH destinationBucket staticWebsiteHostingBucket Now let s run a first deployment with the CLI command cdk deployIt will create the bucket and fill it with the index html file found in my local repository I can see it in my AWS console Access the portfolio from a custom domain nameMy website is now uploaded on the AWS cloud but it would be nicer if anyone could access it using my domain name sls mentor dev If you do not own a domain name AWS Route offers the possibility to buy ones for a fair price In my example dev domains was not available on AWS so I bought it on gandi but you can buy your domain name anywhere you want The important thing is to have access to the name servers after it s yours How to link my S bucket with sls mentor dev It is done in simple steps Create a Route hosted zone that will contain the custom DNS records needed to create this connection Create a HTTPS certificate otherwise my portfolio will only be accessible via http Create a CloudFront distribution allowing to distribute my website all around the world and to use my new HTTPS certificate Create DNS records in my hosted zone to redirect traffic from sls mentor dev and www sls mentor dev to the CloudFront distribution Seems too complicated Using CloudFront allows to use the HTTPS protocol and to deliver my website very quickly around the world thanks to caching Furthermore these steps can be coded in a few lines thanks to the CDK everything left to do is to launch the deployment Let s create the hosted zone by adding this snippet of code under the S bucket definition const DOMAIN NAME sls mentor dev your domain name Create a Route hosted zone to later create DNS records ️Manual action required when the hosted zone was created copy its NS records into your domain s name serversconst hostedZone new HostedZone this DomainHostedZone zoneName DOMAIN NAME Then deploy this change to create the hosted zone cdk deployI have to perform the only manual input required in this tutorial ️very important ️ after deployment Route will create a NS record containing values in my new hosted zone I have to copy them into my DNS s name servers in order to prove my ownership of the domain NS records in the new hosted zone Copied into the domain name servers on gandi On the screenshots I did it using a domain name bought on gandi But it can also be achieved on providers like AWS or any other one Now that I m done with the domain I can create the certificate and set the validation method to fromDns It will automatically communicate with my freshly created hosted zone to validate the authenticity of the certificate ️The certificate MUST be created in the region us east to be compatible with CloudFront that s why I deploy all my resources in this region CloudFront allows for at edge delivery which means that it s not a problem if my visitors are not in the US const WWW DOMAIN NAME www DOMAIN NAME Create the HTTPS certificate ️must be in region us east ️ const httpsCertificate new Certificate this HttpsCertificate domainName DOMAIN NAME subjectAlternativeNames WWW DOMAIN NAME validation CertificateValidation fromDns hostedZone Then time for the CloudFront distribution It is the main node of my architecture It communicates with the certificate I just created to allow HTTPS communication It is the link between the us east bucket and users all around the world thanks to caching there will be minimal latency for end users I specify my bucket as the origin enable a REDIRECT TO HTTPS policy set the domain names with the addition of the www subdomain for optimal compatibility with all browsers and finally reference my new https certificate I also specified an optional responseHeadersPolicy with the ID corresponding to the AWS Managed SecurityHeadersPolicy It s a quick win to improve security in my distribution This best practice is part of sls mentor feel free to check it out Create the CloudFront distribution linked to the website hosting bucket and the HTTPS certificateconst cloudFrontDistribution new Distribution this CloudFrontDistribution defaultBehavior origin new SOrigin staticWebsiteHostingBucket viewerProtocolPolicy ViewerProtocolPolicy REDIRECT TO HTTPS responseHeadersPolicy responseHeadersPolicyId fc f d bed domainNames DOMAIN NAME WWW DOMAIN NAME certificate httpsCertificate Last step redirect requests heading to sls mentor dev and www sls mentor dev to the CloudFront distribution I create DNS records in my hosted zone which have the CloudFront distribution as target These records are A records linking my domain name with the IPv address of the CloudFront distribution Add DNS records to the hosted zone to redirect from the domain name to the CloudFront distributionnew ARecord this CloudFrontRedirect zone hostedZone target RecordTarget fromAlias new CloudFrontTarget cloudFrontDistribution recordName DOMAIN NAME Same from www sub domainnew ARecord this CloudFrontWWWRedirect zone hostedZone target RecordTarget fromAlias new CloudFrontTarget cloudFrontDistribution recordName WWW DOMAIN NAME And I am done Last step is to deploy everything one more time cdk deployBe aware that changes to DNS records can take up to hours to be propagated do not worry if the deployment is successful but your website doesn t work instantlyTime to test it These links should all redirect to the same website always using the https protocol regardless of what I specify	2023-02-01 13:49:25

landing page using Tailwind CSS and no code tools IntroductionA landing page is an important part of any website It s the first thing your visitors will notice so make a good first impression Today in this article we will demonstrate how to create a landing page with Tailwind CSS and no code technologies What is Tailwind CSS Tailwind CSS is a utility first CSS framework for creating bespoke user interfaces quickly It provides a collection of pre designed CSS classes that may be used to easily create complicated designs without the need for unique CSS code Tailwind CSS is a popular choice for front end developers and designers trying to build contemporary flexible websites and applications since it is focused on speed and efficiency What are no code tools Platforms that allow you to construct websites web applications and mobile apps without writing any code are known as no code tools They offer a graphical interface for creating and developing goods allowing you to create complicated functionality by combining pre built blocks templates and drag and drop capabilities These tools are intended for non technical users such as business owners marketers and entrepreneurs who wish to construct their own products without hiring a development team Limey Webflow Bubble Adalo Wix and Squarespace are some prominent no code solutions How to build a website using Tailwind CSSThe first thing we should do is visit the beautiful Tailwind CSS website so that we can see the documentation for using Tailwind CSS It is fairly straightforward to use and the documentation covers everything so learning it is not too challenging Now let s create a basic landing page using Tailwind CSS This code uses HTML for the content and CSS for styling with Tailwind CSS Create a folder on your computer called tailwindcss app and then create an index html file inside of it This is all we need for this very simple Tailwind CSS example Of course it is possible to create even more advanced projects that combine JavaScript frameworks like React with a Tailwind CSS configuration Understanding the basic concepts in this example will make it significantly easier for you to work with more complex Tailwind CSS projects in the future if you are still a beginner Just copy and paste this code into your index html file and then open the file in a web browser to see the landing page lt DOCTYPE html gt lt html gt lt head gt lt meta charset UTF gt lt meta name viewport content width device width initial scale gt lt link href dist tailwind min css rel stylesheet gt lt title gt My

elementum accumsan at id diam Vivamus dui nibh ultricies ut fermentum sit amet dapibus quis dui Donec lacinia leo quis consequat pharetra Ut malesuada lacinia mi eget efficitur lt p gt lt main gt lt body gt lt html gt You should see a landing page with some filler text and an image that automatically changes if you reload the webpage Take a look at the documentation on the Tailwind CSS website and you will see how easy it is to change the style of the landing page The margin padding colours and page layout can all be customised with just a few class changes Honestly the Tailwind CSS documentation is the best place for learning how to use the code With your landing page complete it is time to publish it online There are countless free serverless platforms that allow you to do this like GitHub Pages Vercel and Netlify For other Tailwind CSS installations that use the CLI and frameworks like Next js Laravel and Vite take a look at the Get started with Tailwind CSS page section How to build a website using no code toolsOne of the great things about no code tools is the fact that the bar to entry is very low You don t need to be a programmer to build a website using these tools You can be a designer marketer programmer or even non technical and still learn how to use the tool The no code tool Webflow has a really good example of this on their website which you can see below in this animated gif Step Choosing a no code tool for the landing pageNo code tools are platforms that enable you to create websites and apps without writing any code Choose a tool that you are familiar with and that meets your requirements Personally I chose to use Limey for its ease of use and flexibility Step Brainstorming for the landing page contentIt is critical to plan out your landing page before you begin developing it Determine the goal of your landing page the information it will provide and the features it will have such as graphics text buttons and so on Step Choosing a good templateNo code technologies frequently feature templates that you may use to get started on your landing page Choose a template that is comparable to what you have in mind for your landing page and modify it to meet your requirements Step Integrating the template with Tailwind CSSTailwind CSS is a CSS framework that focuses on functionality and makes it simple to create bespoke designs To include Tailwind CSS into your landing page add the CSS file to your no code tool or link to it in the HTML file s head Step Customising the landing page designCustomise your landing page using the features and tools given by your no code solution Make your landing page aesthetically appealing and user friendly by including photos text buttons and other features Test your landing page before posting it to confirm that everything functions as it should Examine the layout functionality and usability for any flaws Step Deploy the landing page onlineIt s time to publish your landing page after you ve tested it and ensured that everything works properly Make your landing page available on your website or domain Final thoughtsTo summarise creating a landing page with Tailwind CSS and no coding tools is an excellent method to create a professional looking landing page without writing any code You can create a landing page that makes a fantastic first impression on your visitors with a little thought customisation and testing Another great option is to use a platform like Tailmars where most of the work is done and you just need to move code around to get your page looking the way you want	2023-02-01 13:14:33
海外TECH	DEV Community	Ultimate guide to master JavaScript's reduce functions	https://dev.to/costamatheus97/ultimate-guide-to-master-javascripts-reduce-functions-2gb4	Ultimate guide to master JavaScript x s reduce functionsThe reduce function in JavaScript is a powerful tool for transforming an array of values into a single value It is a higher order function which means that it takes one or more functions as arguments and returns a new function In this article we will cover the basics of how to use the reduce function and provide some examples to help you get started What is the reduce function and how does it work The reduce function is a method that can be called on an array object in JavaScript It takes two arguments a callback function and an optional initial value The callback function is called on each element in the array starting with the first element and continuing until all elements have been processed The result of each call to the callback function is used as the input to the next call and the final result of the last call is returned by the reduce function The initial value is an optional argument that can be used to set the starting value for the first call to the callback function If an initial value is not provided the first call to the callback function will be made with the first two elements in the array Cool right Now let s see how to actually use it To use the reduce function you must provide a callback function that takes two arguments the accumulator and the current value The accumulator is the result of the previous call to the callback function and the current value is the value of the current element in the array The callback function should return a new value that will be used as the accumulator in the next call to the callback function Here is a simple example of how to use the reduce function to sum the elements in an array const numbers const sum numbers reduce acc curr gt acc curr console log sum In this example the initial value is set to and the callback function adds the current value to the accumulator The result of each call to the callback function is used as the input to the next call and the final result of the last call is returned by the reduce function More examples of the reduce function Finding the maximum value in an array const numbers const max numbers reduce acc curr gt acc gt curr acc curr console log max Counting the frequency of elements in an array const words apple banana apple cherry const frequency words reduce acc curr gt acc curr acc curr return acc console log frequency apple banana cherry Flattening an array of arrays const arrays const flattened arrays reduce acc curr gt acc concat curr console log flattened Transforming an array of objects into a hashmap const users id name Matheus id name Lucas id name Victor const usersHashMap users reduce users currentUser gt const id rest currentUser users id rest return users console log usersHashMap name Matheus name Lucas name Victor BONUS Typescript example of a dynamically created object with type inference from the input to the outputconst usersRouter getUser users get const createApi lt T extends key string string gt router T gt return Object entries router reduce api method endpoint keyof T string gt api method gt fetch endpoint return api as Record lt keyof T gt Promise lt any gt gt const usersApi createApi usersRouter const result usersApi getUser You get autocomplete on the dynamic API methods Final considerationsThe reduce function is a powerful weapon that we can use to transform data with more freedom With it we can achieve the same results as map or filter but with more control to solve a lot of other problems A reminder that reduce is a higher order function not exclusive to the JavaScript language Let me know if you have any questions	2023-02-01 13:13:28
