海外TECH	DEV Community	Building Resilient Systems with Idempotent APIs	https://dev.to/karishmashukla/building-resilient-systems-with-idempotent-apis-5e5p	Building Resilient Systems with Idempotent APIsNetworks are unreliable but our systems cannot be What is Idempotency Idempotency is a property of API design that ensures that making the same request multiple times produces the same result as making it once In other words no matter how many times an idempotent API endpoint is invoked with the same set of parameters the outcome remains unchanged after the first successful request In the context of API designing idempotency is crucial to prevent unintended side effects and ensure the predictability and reliability of the API It allows clients to safely retry requests without causing any data duplication overwriting or other unwanted effects Idempotent API for file upload Image by authorIdempotency of an API is determined by the changes it makes to the system not the response it provides To better understand the above statement consider this example Consider an API endpoint that is designed to sign up a new user account in a web application If this API is idempotent it means that no matter how many times the API is called with the same input data e g the same email and password it will create the user account only once and any subsequent invocations will have no further effect The API may return a successful response e g status code for the first request and subsequent requests indicating that the user account already exists but the system state remains unchanged The idempotency is evaluated based on the side effect of creating the user account not the response message Real World Use CasesPayment Processing Idempotent APIs prevent double charging when processing payments ensuring consistent and accurate billing Order Processing Idempotent APIs in e commerce platforms avoid duplicate orders or unintended changes to order status File Uploads Idempotent APIs for file uploads prevent unnecessary duplication ensuring files are stored only once even during retries or network issues Subscription Management Idempotent APIs handle subscription requests without creating duplicate subscriptions or unwanted changes to user preferences Distributed Systems Idempotent APIs in distributed systems maintain consistency and handle failures gracefully enabling safe retries without data inconsistencies Stateful Operations Idempotent APIs for stateful operations maintain workflow consistency by allowing repeated requests without affecting the final state How to Implement Idempotency in API Design Assign unique identifiers Use UUIDs or other unique identifiers for each request to track and identify requests Idempotent HTTP methods Design APIs using idempotent HTTP methods like GET PUT and DELETE These methods ensure that multiple identical requests have the same effect as a single request Expiration time for idempotency keys Set a reasonable expiration time for idempotency keys to ensure they are valid only for a certain period Response codes and headers Utilize appropriate HTTP status codes e g and headers e g ETag Last Modified to indicate idempotency and successful processing HTTP Methods and IdempotencyIdempotent methods are those that can be safely repeated multiple times without changing the result beyond the initial operation The HTTP methods that are idempotent are GET HEAD PUT and DELETE POST is not idempotent This is because each time you make a POST request it creates a new resource on the server leading to a different result with each request Subsequent POST requests will create additional resources altering the state of the server making it non idempotent What are Idempotency Keys Before making an API call the client requests a random ID from the server which acts as the idempotency key The client includes this key in all future requests to the server The server stores the key and request details in its database When the server receives a request it checks if it has already processed the request using the idempotency key If it has the server ignores the request If not it processes the request and removes the idempotency key ensuring processing is done only once ExampleIn the example below the server generates an idempotency key and returns it to the client in the response header Idempotency Key The client must include this key in all subsequent requests The server checks if it has already processed the request using the idempotency key and ensures exactly once processing Note This example is not intended for production use instead it serves to illustrate the fundamental concept of idempotent keys Node js Express const express require express const app express const v uuidv require uuid const idempotencyKeys new Set app use express json app post api resource req res gt const idempotencyKey req header Idempotency Key if idempotencyKeys has idempotencyKey return res status json message Request already processed const resourceId uuidv add logic to create the resource idempotencyKeys add idempotencyKey return res status json resource id resourceId app listen gt console log Server started on port Python Flask from flask import Flask request jsonifyimport uuidapp Flask name idempotency keys set app route api resource methods POST def create resource idempotency key request headers get Idempotency Key if idempotency key in idempotency keys return jsonify message Request already processed resource id str uuid uuid add logic to create the resource idempotency keys add idempotency key return jsonify resource id resource id if name main app run ConclusionIdempotent APIs play a crucial role in ensuring the reliability consistency and efficiency of a system If you

海外TECH	DEV Community	Quick Guide To Set Up Your React App Ready For Development.	https://dev.to/meganad60/quick-guide-to-set-up-your-react-app-ready-for-development-1hm9	Quick Guide To Set Up Your React App Ready For Development React is one of the most widely used JavaScript libraries in creating software interfaces React offers several tools that make it stand out and popular in today s software development industry Thus it s a great feat to be a React developer The purpose of this article is to provide a quick guide in creating your first React app and setting it ready for development Before we set up our first React app let s know what React entails and its benefits This will give us a thorough insight into React as we journey through this career in becoming a React developer Let s get started What is React React is a JavaScript library used in developing interactive and robust User Interfaces UI In other words React is used to create front end web applications React can be used to develop Single Page Applications SPAs using independent and reusable components thereby increasing her readability and maintainability Jordan Walke ーa software engineer at Facebook now known as Meta ーdeveloped React Jordan Walke first came up with a prototype known as FaxJS FaxJS was initially deployed to the Facebook News feed in On May React was officially launched and made an open source at the JavaScript Conference in the US Over the years React has evolved to include several features which serve as frameworks for developing complete applications Some of these frameworks include Next js Gatsby and React Native amongst others Next js and Gatsby js frameworks develop backend servers of web applications React Native is used to develop mobile applications such as iOS and Android mobile apps Benefits of ReactReact is the most widely used JavaScript library This is because of the benefits React offers In this section we shall examine the notable benefits of React Let s get started Web App Development React powered frameworks are used to develop full Web applications For instance React powered frameworks provide features for server side rendering data fetching routing and so on These frameworks are maintained by various communities which include Next js maintained by Vercel Gatsby maintained by Netlify and Remix maintained by Shopify amongst others Mobile App Development React Native ーa React powered framework ーis used to develop mobile applications React Native is an open source JavaScript Framework that is used to develop iOS and Android mobile apps Easy Maintainability React applications are developed using components These components are independent and reusable In other words these components work separately and can be used in several parts of the application Thus increases the readability and maintainability of React codes Reusability React components are independent pieces of code These components work separately and can be used in various parts of the application Thus reduces the amount of code to be written and ensures the effectiveness of the application Testing and Debugging React provides developers with tools to test and debug their codes and ensure the effectiveness and efficiency of their software Some such tool includes Jest React Developer Tools and so on Developers can test and debug their codes with ease and ensure they work correctly as expected Steps In Setting Up React ApplicationsThis section will guide you through the steps in creating your first React app ready for development Note that we shall be using the officially recommended process of creating a React app Let s get started with the various steps Step ーInstall Node jsYou need to install Node js for the local development of your React app To install Node js visit and follow the instructions STEP ーCreate a Project folderCreate a project folder and navigate to the directory of your project folder using your terminal as seen in the codes below C Users Usersname Desktop gt mkdir react projectC Users Usersname Desktop gt cd react projectSTEP ーCreate React AppCreate your new React app by typing any of the commands below C Users Usersname Desktop react project gt npx create react app my appORC Users Usersname Desktop react project gt npm init react app my appFor yarn users run C Users Usersname Desktop react project gt yarn create react app my appThe installation process takes a while to complete When completed a folder named my app will be created containing several files and folders just like the below structure Note that my app is the name of your React app and can be any name of your choice my app node modules public favicon ico index html src App css App js App test js index css index js logo svg gitignore package json README mdSTEP ーStart the serverIn your terminal navigate to the app directory where package json is located The package json file contains scripts that give you access to run React script commands such as start build test etc Start the development server as seen in the codes below C Users Usersname Desktop react project my app gt npm startThe above command starts the development server and opens your default browser The development server is run on localhost with the image below displayed on your screen An impressive feature of React development server is the Hot Module Replacement HMR The HMR updates the web page without reloading when a component is modified In conclusion we ve understood what React entails and how important it is in the software development industry we ve also achieved a great step in setting up a React app ready for development Congratulations on our progress Explore other tools and functionalities in React to grow and perfect your skills as a React developer I hope you find this article useful Follow me on Twitter and LinkedIn as we share insightful and innovative ideas	2023-07-28 15:04:09
