海外TECH	DEV Community	What Is GraphQL: Comprehensive Guide	https://dev.to/arsalanmee/what-is-graphql-comprehensive-guide-2i1d	What Is GraphQL Comprehensive GuideAre you looking for a better way to manage your API requests and responses Do you want a more efficient way to retrieve and manipulate data from your server Look no further than GraphQL In this comprehensive guide we ll take a deep dive into what GraphQL is how it works and why it s quickly becoming a popular alternative to traditional RESTful APIs IntroductionIf you re unfamiliar with GraphQL you might be wondering what all the hype is about GraphQL is a query language for your API It is designed to give you more control over the data you request and the way you receive it Unlike traditional RESTful APIs which require you to make multiple requests to retrieve related data GraphQL allows you to retrieve all the data you need in a single request This not only makes your code more efficient but it also reduces the amount of data you need to send over the network What is GraphQL GraphQL is a query language and runtime for APIs that was developed by Facebook in and released as an open source project in It allows clients to define the structure of the data they need and the server responds with only that data This means that clients can avoid making multiple requests to retrieve related data and can instead retrieve all the data they need in a single request How Does GraphQL Work In this diagram the client sends a GraphQL query or mutation to the server The server parses the query or mutation validates it against the schema and resolves it with data The server then sends a response back to the client with the requested data The GraphQL SchemaAt the heart of GraphQL is the schema which defines the types of data that can be queried and the relationships between them The schema is a hierarchical tree structure that defines the available fields their types and any arguments they take ResolversWhen a client makes a query the server uses resolvers to fetch the requested data Resolvers are functions that are responsible for retrieving data from a data source such as a database or API and returning it in the shape defined by the schema QueriesQueries are requests for data that are made by the client They specify the fields that the client wants to retrieve as well as any arguments that the client wants to pass to the resolver Here s an example GraphQL query query user id name email posts title content comments author text In this example we are querying for a specific user with the ID We want to retrieve the user s name and email as well as all of their posts For each post we also want to retrieve the title content and all of the comments on that post including the author and text of each comment MutationsMutations are similar to queries but instead of retrieving data they modify data on the server They can be used to create update or delete data Advantages of GraphQLIncreased EfficiencyOne of the main advantages of GraphQL is that it allows clients to retrieve all the data they need in a single request This reduces the number of requests that need to be made and the amount of data that needs to be sent over the network More Flexible QueriesWith GraphQL clients have more control over the data they request They can specify exactly which fields they want to retrieve and can even request nested fields This allows for more flexible queries that can adapt to the needs of the client VersioningBecause the schema is the contract between the client and the server changes to the schema can be versioned and communicated to clients This allows for more controlled changes to the API without breaking existing clients Easier to Learn GraphQL has a relatively simple syntax and a small set of core concepts This makes it easier to learn and use compared to other APIs which often require knowledge of multiple technologies and languages Disadvantages of GraphQLSteep Learning CurveAlthough GraphQL is relatively easy to learn it can still have a steep learning curve for developers who are used to working with traditional RESTful APIs This is because GraphQL requires a different way of thinking about API design and development OverheadBecause GraphQL provides so much flexibility it can be more complex and require more overhead to set up compared to traditional RESTful APIs This can be a disadvantage for smaller projects or for teams with limited resources Lack of StandardizationGraphQL is still a relatively new technology and as such there is less standardization in the way it is implemented compared to traditional RESTful APIs This can lead to inconsistencies in the way GraphQL is used across different projects and organizations GraphQL vs RESTGraphQL and REST are two different approaches to building APIs and each has its own advantages and disadvantages REST is a well established standard with a clear set of guidelines and conventions for building APIs GraphQL on the other hand provides more flexibility and allows for more efficient data retrieval How to Implement GraphQLImplementing GraphQL requires setting up a server that supports GraphQL queries and mutations as well as defining a schema that describes the types of data that can be queried There are a number of tools and frameworks available for implementing GraphQL including Apollo Relay and Prisma Best Practices for Using GraphQLSome best practices for using GraphQL include keeping your schema simple and easy to understand minimizing the number of round trips between the client and server and using caching and batching to improve performance Real World ExamplesGraphQL is used by a number of large companies and organizations including GitHub Shopify and The New York Times These companies use GraphQL to improve the performance and efficiency of their APIs and to provide a more flexible and customizable experience for their clients Future of GraphQLGraphQL is still a relatively new technology but its popularity is growing rapidly As more companies adopt GraphQL and more tools and frameworks are developed we can expect to see continued growth and innovation in the GraphQL ecosystem ConclusionGraphQL is a powerful and flexible tool for building APIs that can help you to improve the efficiency and flexibility of your code While it may require a bit of a learning curve it is well worth the investment for teams and projects that need to manage large amounts of data and complex API requests FAQs What are some advantages of using GraphQL over traditional RESTful APIs Some advantages of using GraphQL over traditional RESTful APIs include More efficient data retrieval GraphQL allows you to retrieve only the data you need which can result in faster and more efficient API calls More flexibility GraphQL allows clients to specify exactly what data they need which can be especially useful in situations where different clients have different data requirements Better developer experience With GraphQL developers can easily explore the data available in the API and get immediate feedback on their queries What are some disadvantages of using GraphQL Some disadvantages of using GraphQL include Steep learning curve While GraphQL is relatively easy to learn compared to some other technologies it can still require a significant investment of time and effort to get up to speed Overhead Because GraphQL provides so much flexibility it can be more complex and require more overhead to set up compared to traditional RESTful APIs Lack of standardization Because GraphQL is still a relatively new technology there is less standardization in the way it is implemented compared to traditional RESTful APIs How do I get started with implementing GraphQL in my project To get started with implementing GraphQL in your project you ll need to set up a server that supports GraphQL queries and mutations and define a schema that describes the types of data that can be queried There are a number of tools and frameworks available for implementing GraphQL including Apollo Relay and Prisma Can I use GraphQL with any programming language Yes you can use GraphQL with any programming language Because GraphQL is a query language it can be used with any backend technology that can receive and respond to HTTP requests What are some best practices for using GraphQL in production environments Some best practices for using GraphQL in production environments include Keeping your schema simple and easy to understand Minimizing the number of round trips between the client and server Using caching and batching to improve performance Adding authentication and authorization to your GraphQL API Monitoring and logging your API to identify and address issues quickly	2023-07-06 09:39:26
海外TECH	DEV Community	Coding Period GSoC'23 | Week 3 + 4 + 5	https://dev.to/prerna0202/coding-period-gsoc23-week-3-4-5-388b	Coding Period GSoC x Week Welcome back to another progress update on my Google Summer of Code GSoC journey If you haven t already make sure to catch up on my previous blog posts covering Week and Week In this blog I ll be sharing my accomplishments and developments from Weeks and Work Done th June th July As mentioned in my previous blog I had almost completed the state machine task and the simulator crash recovery task However during third and half of the fourth weeks I had scheduled university exams that required my attention so I couldn t work on the project during that time I had informed my mentors about this in advance Once my exams concluded I resumed working on my project During the last meeting with my mentors just before my exams we discussed making some changes to the simulator crash recovery task Also I identified an issue with the state machine task So I started my work back by addressing these changes and issues and completed the necessary pull requests for both tasks Here are the changes we decided upon Simulator Crash Recovery Task Initially I was calling the autosave function alongside the scheduleBackup function However after discussions we agreed to schedule autosave at specific time intervals So I modified the code accordingly Now we check for any increments in the backups every three seconds If an increment is detected in the length of backups the autosave function is triggered otherwise it is skipped State Machine Task There was an issue where the state would change from normal to an error in real time but to revert from error to normal we had to click on the simulation area which was not an optimal user experience I addressed this issue and now the state revert from error to normal in real time Additionally some suggested changes by mentor were made and pushed After completing these tasks I started working on a new task which involved creating a better system for handling high impedence values In CircuitVerse we have two elements related to high impedence conditions tristate and controlled inverter The controlled inverter was broken initially so first I fixed it Following that I identified and resolved several issues related to the tristate element which involved fixing shortcomings and ensuring proper functionality I verified the changes using Logisim and now both the tristate and controlled inverter are functioning correctly Next I began working on another task which involved exposing helpful functions for debugging circuits I created four functions for this purpose load This function takes circuit data as a parameter and draws the circuit on the canvas removeBugNodes This function removes nodes with bugs from the circuit Next This function takes the circuit to the next state Previous This function takes the circuit to the previous state These functions will greatly aid in debugging circuits I plan to discuss the implementation and explore other helpful functions which we can implement during my upcoming meeting Pull Requests Implemented safe recovery from simulator crashImplemented state machine for simulatorBetter system for high impedence valuesAdded helpful functions for debugging of circuit So What s Next As per my proposal timeline I aim to complete the remaining two tasks before the mid term evaluation I am determined to put in my utmost effort to accomplish these tasks and ensure their completion before the mid term evaluation In the upcoming week my primary focus will be on completing the following tasks Simulation Stack Exceeded Error I plan to develop a solution that allows the identification of components that are being added to the simulation stack an unusually large number of times leading to the error By addressing this issue we can enhance the stability and efficiency of the simulator Identifying and Modifying Selected Components Another task on my agenda is to implement a feature that enables the identification of the currently selected component on the canvas This functionality will empower users to modify the properties of the selected component conveniently within the global scope That concludes my progress update for Weeks and of my GSoC project I will continue to share regular updates on my journey so stay tuned for more	2023-07-06 09:38:12

海外TECH	DEV Community	How to Use GitHub Copilot to Become More Productive Developer	https://dev.to/farhadi/how-to-use-github-copilot-to-become-more-productive-developer-21pp	How to Use GitHub Copilot to Become More Productive Developer There are a number of AI tools for developers emerging on the market But in my mind GitHub Copilot stands above the rest because of its usability seamless IDE integration and remarkable enhancements to developer productivity Copilot offers a variety of AI tools that have radically streamlined my experience as a software developer I ve used it to generate code tests and even simple applications It s also great for debugging refactoring and documenting existing code Weirdly using Copilot has caused me to develop features faster than business stakeholders can review them It s important to note that AI tools including Copilot can be blatantly wrong apologize or not when corrected and then confidently produce the same error But as long as you re aware of the downsides of AI tools and have enough coding knowledge to recognize when they re incorrect you can mitigate them on the path to substantially improved productivity How to Setup GitHub CopilotFor setup and basic usage of Copilot check out the docs You can add on Copilot to an individual or business account and there s a free trial and reasonable pricing after the trial After adding Copilot to your GitHub account you ll want to install the plugins for your IDE and log into GitHub to access Copilot In this article we ll use these Visual Studio Code extensions GitHub

evolves these products I haven t yet received access to Copilot Voice or Copilot X for Pull Requests so my perspective on these are limited and based on GitHub s preview docs PrivacyBefore jumping into some key use cases for Copilot a quick note on privacy Basically if you trust GitHub to host your source code you can likely trust what they do with your Copilot prompts and code snippets See their FAQ docs and Privacy Statement Use Cases for GitHub CopilotThe uses cases for GitHub Copilot are numerous especially when you add in the preview features of Labs Chat and Voice Using Copilot s

CodeCopilot Labs Copilot Chat Copilot VoiceLanguage TranslationCopilot Labs Copilot ChatDebuggingCopilot Labs Copilot ChatRefactoringCopilot Labs Copilot ChatTest GenerationCopilot Copilot Nightly Copilot Labs Copilot ChatCode ReviewsCopilot ChatVoice Driven DevelopmentCopilot VoiceCode GenerationCopilot is known for its code completion features If it s given a comment in the code or you type the beginnings of a line of code Copilot will suggest a solution that you can accept ignore or explore alternatives It s referred to as ghost text Once you have the Copilot extension installed and you re logged in code completion is as simple as typing instructions and hitting the Tab key once the suggestion comes up A comment prompt in Ruby that Copilot uses to create a method and invocationTaking code completion one step further Copilot Chat can take a single prompt and generate instructions for building an entire application I asked it to create a REST API in Node with CRUD functions for products and it generated functional code Impressive overall Given the same prompt ChatGPT also gave me instructions for how to run the code which was nice Copilot Voice can also write or edit code based on voice commands Most of the time using the keyboard with Copilot code completion is faster than dictating lines of code with Voice But it s compelling to think about using Copilot Voice to create and run code without having to type or stare at a screen Explaining CodeI often have to stare at a screen to figure out what a block of code is doing Sometimes it s legacy code where I don t understand the business context Sometimes it s using a particular library I m not used to Sometimes I curse the person who wrote it even if it s me Below is some code generated by Copilot Chat from my REST API in Node prompt from above app get products id req res gt const id req params id const product products find p gt p id id if product res json product else res status json error Product not found I took this code and fed it into the Explain feature in Copilot Labs Here s the response Here is the explanation for the code above  We define a route with the route path products id The colon in the path indicates that it is a route parameter The value of the route parameter will be available in req params For example if the route path is products id and we make a request to products then the value of req params will be id We get the id from req params and find the product with the given id from the products array If a product with the given id exists we return it Otherwise we send a error response with the error message Product not found This is a pretty straightforward segment of code and the response is clear and straightforward as well It would be easy to add this as documentation in a code comment above the function Another good example is regular expressions I understand how regular expressions work but I don t often have the patience to figure out what a particular regex is doing I fed Copilot Chat this giant regex statement for email validation a z amp a z amp x x xb xc xe xf x x xb xd xf x x xb xc xe xf a z a z a z a z a z a z a z a z x x xb xc xe xf x xa x xf x x xb xc xe xf It explained the regex at a high level indicating it was broken into the local and domain parts representing before and after the sign in an email address Then it described allowable characters in each part Quite helpful  Language TranslationDevelopers are often required to quickly learn new languages and frameworks Copilot Labs and Chat make this pretty easy Here s an array of products in JavaScript and Ruby that was converted by Copilot let products id name Product price id name Product price id name Product price products id name Product price id name Product price id name Product price This is a very simple example so let s try making this into a class and going the other way from Ruby to JavaScript class Product attr reader name price def initialize name price name name price price endendclass Product constructor name price this name name this price price This checks out For good measure I tested TypeScript as well and it worked perfectly too DebuggingThis is a very handy feature You can give Copilot Chat or Labs problematic code or error messages and it will indicate what it thinks the issue is Copilot Labs Fix Bug Brush FeatureI can t tell you how many hairs I ve pulled out because I couldn t find what amounted to a syntax error Copilot s ability to fix bugs just makes me happier and hairier You can also give Copilot Chat an error message with no other prompt and it can tell you the issue I arbitrarily removed a dot from the Node REST API code products productIndex id req body I copied pasted the error message in Chat and it responded with Looking at the code excerpt you provided it seems that the issue is on line where there is a syntax error in the object literal The before req body is causing the error It should be just one dot instead of two This is both correct the line and source of the error and incorrect that it should be only one dot It then gave me a code snippet with three dots which is also correct As I mentioned at the outset you ve gotta double check AI s work Still I m impressed by Copilot s ability to parse an error message describe what it thinks is wrong and suggest a fix RefactoringAnother great use case is refactoring Consider the code below def price with discount price price discount rate endThis simple price calculation doesn t factor in nil values strings that should be numbers or reasonable values for price or discount rate We need the code to do this Ensure price is an integer or float not nil Ensure price is not negativeEnsure discount rate is a float not nil Ensure discount rate is not negative and less than or equal to Copilot Chat handles this with ease def price with discount price discount rate raise ArgumentError Price must be a positive number unless price is a Numeric amp amp price gt raise ArgumentError Discount rate must be a float between and unless discount rate is a Float amp amp discount rate gt amp amp discount rate lt price price discount rate endTest GenerationUsing Copilot to generate tests is technically a subset of Code Generation above but I felt it was so useful it warranted its own mention Generating unit tests for code can be tedious if you re trying to cover happy and sad paths primary use cases and edge cases Our price with discount code above needs test cases to ensure an error is raised if price or discount rate don t meet the requirements In addition we might want to test the following A price without a discount rateA price with a reasonable discount rate for example a discount A price with a discount rate for example if we want to give the product away With these and our previous error cases here s what Copilot Chat generated after a little fine tuning re prompting and switching from Minitest to Rspec RSpec describe Product do describe price with discount do context when given a valid price and discount rate do it returns the price with the discount applied do product Product new Test Product expect product price with discount product price product discount rate to eq end end context when given a nil price do it raises an ArgumentError with an appropriate message do product Product new Test Product nil expect product price with discount product price product discount rate to raise error ArgumentError Price must be a positive number end end context when given a price less than do it raises an ArgumentError with an appropriate message do product Product new Test Product expect product price with discount product price product discount rate to raise error ArgumentError Price must be a positive number end end context when given a nil discount rate do it raises an ArgumentError with an appropriate message do product Product new Test Product nil expect product price with discount product price product discount rate to raise error ArgumentError Discount rate must be a float between and end end context when given a discount rate less than do it raises an ArgumentError with an appropriate message do product Product new Test Product expect product price with discount product price product discount rate to raise error ArgumentError Discount rate must be a float between and end end context when given a discount rate greater than do it raises an ArgumentError with an appropriate message do product Product new Test Product expect product price with discount product price product discount rate to raise error ArgumentError Discount rate must be a float between and end end endendOne test for valid input five for invalid input All six work and I

海外TECH	DEV Community	Sticky sessions with Apache APISIX - the demo	https://dev.to/apisix/sticky-sessions-with-apache-apisix-the-demo-2j8g	Sticky sessions with Apache APISIX the demoLast week we described the concept behind sticky sessions you forward a request to the same upstream because there s context data associated with the session on that node However if necessary you should replicate the data to other upstreams because this one might go down In this post we are going to illustrate it with a demo The overall designDesign options are limitless I ll keep myself to a familiar stack the JVM Also as mentioned in the previous post one should only implement sticky sessions with session replication The final design consists of two components an Apache APISIX instance with sticky sessions configured and two JVM nodes running the same application with session replication The application uses the following DependencyDescriptionSpring BootEases the usage of Spring librariesSpring MVCAllows offering HTTP endpointsThymeleafView technologySpring SessionOffers an abstraction over session replicationHazelcast embedded Implements session replicationSpring SecurityBinds an identity to a user sessionThe design looks like the following app and app are two instances of the same app I didn t want to overcrowd the diagram with redundant data The heart of the applicationThe heart of the application is a session scoped bean that wraps a counter which can only be incremented Component SessionScopepublic class Counter implements Serializable private int value public int getValue

setTypeClass MapSession class config getSerializationConfig addSerializerConfig serializerConfig return config Choose a random port to avoid port conflictAllow Hazelcast to search for other instances and automagically form a cluster It s going to be necessary when deployed as per our designCopy pasted from the Spring Session documentation Configuring Spring SecurityMost Spring Session examples somehow use Spring Security and though it s not strictly necessary it makes the design easier I want to explain why first One can think about sessions as a gigantic hash table In regular applications the key is the JSESSIONID cookie value the value another hash table of session data However the JSESSIONID is specific to the node The app will give a different JSESSIONID if one uses another node Since the key is different there s no way to access the session data even if the session data is shared across nodes To prevent this loss we need to come up with a different key Spring Security allows using a principal or the login name as the session data key Here s how I set up a basic Spring Security configuration Beanpublic SecurityFilterChain securityFilterChain UserDetailsService service HttpSecurity http throws Exception return http userDetailsService service authorizeHttpRequests authorize gt authorize requestMatchers PathRequest toStaticResources atCommonLocations permitAll anyRequest authenticated formLogin form gt form permitAll defaultSuccessUrl build The default in memory user details service doesn t allow custom user details classes I had to provide my own Allow everybody to access static resources at common locationsAll other requests must be authenticatedAllow everybody to access the authentication formRedirect to the root if successful which maps the above controller Putting our design to the testBeside the counter I want to display two additional pieces of data the hostname and the logged in user For the hostname I add the following method to the controller ModelAttribute hostname private String hostname throws UnknownHostException return InetAddress getLocalHost getHostName Displaying the logged in user requires an additional dependency lt dependency gt lt groupId gt org thymeleaf extras lt groupId gt lt artifactId gt thymeleaf extras springsecurity lt artifactId gt lt dependency gt On the page it s straightforward lt DOCTYPE html gt lt html xmlns th xmlns sec gt lt gt lt body gt lt td sec authentication principal label gt Me lt td gt lt gt Add the sec namespace It s not necessary but may help the IDE to help youRequire the underlying UserDetail implementation to have a getLabel methodLast but not least we need to configure Apache APISIX with sticky sessions as we saw last week routes uri upstream nodes webapp webapp type chash hash on cookie key cookie JSESSIONID ENDHere s the design implemented on Docker Compose services apisix image apache apisix debian volumes apisix config yml usr local apisix conf config yaml ro apisix apisix yml usr local apisix conf apisix yaml ro ports depends on webapp webapp webapp build webapp hostname webapp webapp build webapp hostname webapp Use the previous configuration fileOnly expose the API Gateway to the outside worldSet the hostname to display it on the pageWe can log in using one of the two hard coded accounts I m using john with password john and label John Doe Notice that Apache APISIX sets me on a node and keeps using the same if I refresh We can try to log in with the other account jane jane from a private window and check the counter starts from Now comes the fun part Let s stop the node which should be hosting the session data here webapp and refresh the page docker compose stop webappWe can see exciting things in the logs Apache APISIX can no longer find the webapp so it forwards the request to the other upstream that it knows webapp The request is still authenticated it goes through Spring SecurityThe framework gets the principal out of the requestIt queries Spring SessionAnd gets the correct counter value that Hazelcast replicated from the other nodeThe only side effect is an increased latency because of Apache APISIX timeout It s seconds by default but you can configure it to a lower value if needed When we start webapp again everything works as expected again ConclusionIn this post I described a possible setup for sticky sessions with Apache APISIX and replication involving the Spring ecosystem and Hazelcast Many other options are available depending on your stack and framework of choices The complete source code for
