5 best libraries for making AJAX calls in React

Are you looking to make ajax calls in React?  #react #reactjs #javascript

  • One of the questions many React beginners ask: “What’s the React way to fetch data from the server” or “How should I make AJAX calls in React”?
  • So, in this article I will try to answer this basic question and list down 5 simple libraries for making AJAX calls in React.
  • In the former, official React tutorial, they use jQuery to fetch data from the server.
  • Here is how a simple API call is made, with jQuery: – – P.S. Snippet is from React’s former official tutorial.
  • However, jQuery is a big library with many functionalities – So, it doesn’t make sense to use it just for making API calls (Unless you are already using it for a bunch of other tasks).

I have been working with React for the last two years. One of the questions many React beginners ask: "What’s the React way to fetch data from the ser.

In preparation for the DevUp keynote a few weeks ago, I took some time to learn the minimum amount possible to demonstrate code splitting in React. Now your first reaction is probably… As part of the…

TypeScript + Webpack: Super Pursuit Mode – webpack – Medium

  • Add fork-ts-checker-webpack-plugin as a devDependency of your project and then amend the webpack.config.js to set ts-loader into transpileOnly mode and drop the plugin into the mix:var ForkTsCheckerWebpackPlugin = webpackConfig = { // other config… context: __dirname, // to automatically find tsconfig.json module: { rules: [ { test: /\.
  • $/, loader: ‘ts-loader’, options: { // disable type checker – we will use it in fork plugin transpileOnly: true } } ] }, plugins: [ new ForkTsCheckerWebpackPlugin() ]};If you’d like to see an example of how to use the plugin then take a look at a simple example and a more involved one.HappyPackNot so long ago I didn’t know what HappyPack was.
  • Isn’t multi-threading great?ts-loader did not initially play nicely with HappyPack; essentially this is because ts-loader touches parts of webpack’s API that HappyPack replaces.
  • id=ts’ } ] }, plugins: [ new HappyPack({ id: ‘ts’, threads: 2, loaders: [ { path: ‘ts-loader’, query: { happyPackMode: true } } ] }), new ForkTsCheckerWebpackPlugin({ checkSyntacticErrors: true }) ]};Note that the ts-loader options are now configured via the HappyPack query and that we’re setting ts-loader with the happyPackMode option set.There’s one other thing to note which is important; we’re now passing the checkSyntacticErrorsoption to the fork plugin.
  • Do note that, as with HappyPack, the thread-loader is highly configurable.If you’d like to see an example of how to use thread-loader and cache-loader then once again we have a simple example and a more involved one.All This Could Be Yours…In this post we’re improving build speeds with TypeScript and webpack in 3 this plugin in play ts-loader only performs transpilation.

If you’re like me then you’ll like TypeScript and you’ll like module bundling with webpack. You may also like speedy builds. That’s completely understandable. The fact of the matter is, you sacrifice…

React Native and ReactJS – Ahmed Mahmoud – Medium

React Native and ReactJS  #react #frontenddevelopment #webdevelopment #reactjs #reactjs

  • React Native and ReactJSThey’re not quite the sameReact Native is a framework that lets you build mobile apps for different platforms using only javascript, even few contributors customized it to build desktop apps (Mac and Windows).
  • It’s quite similar to ReactJS in a way, however there are some differences between React Native and ReactJS.Is a framework:React Native is a framework, but ReactJS is a JS library.
  • Meaning, for ReactJS you’ll need a bundler like webpack and then you’ll figure out which modules you’ll need for the project, on the other hand, you won’t need any bundler or any other tools to bootstrap your project, only react-native-cli.
  • Doesn’t have HTML:In React Native, you won’t have html elements, you’ll have instead alternative components that work in a similar way, and they map to actual IOS and Android UI components that renders on the app.Because you’re not rendering HTML, you can’t use any ReactJS library that renders HTML, but you most probably will find alternative React Native libraries here.CSS only in JS:In React Native, styling is only done in JS, and it’s not exactly CSS, and it doesn’t always behave like it, nevertheless it looks pretty much like CSS.No CSS Animations:In React Native, you don’t have CSS Animations, the recommended way to animate a component is using Animated API.Developer tools for Code, not for UI:You still can use the same Chrome DevTools to debug your app, also you can use Redux DevTools to inspect the state of your app, but still you can’t inspect the UI with Chrome DevTools, you’ll have to use the platform native inspector (XCode/Android studio).
  • Tools:XCode (for IOS)Andriod Studio (for Andriod)Device (if you don’t want to run the app only on simulators)Here’s a React Native crash course that’ll help you get started really quickly.

React Ecosystem Setup — Step-By-Step Walkthrough

  • An issue with using a bundle instead of our source code is that it makes debugging more difficult, because the stack trace now refers to our bundle file.
  • Using the flag during development means webpack will watch our files and re-generate the bundle every time we save a change.
  • This code is telling webpack to test the files in our directory and look for the filenames matching the regex in the property.
  • Now we can use ES6 code and the bundle generated by webpack will contain only ES5 code.
  • We’ll have to add a term to our file to tell it that we’re writing React code.

Understand what React, Webpack, and Babel are doing and how to configure them yourself.

  • They are the future.I built a Progress Web App of WhatsApp Web using Webpack 2.0, React and Express.Note: This is not a complete clone of WhatsApp Web but minimal one to have an understanding of how to create a PWA app.Case StudyMain aim of PWA apps should be making the load time of webapp faster.Server Side RendingServer Side Rendering (App shell architecture) is a way of making the load time faster without JavaScript .
  • Sample Code of match api from react-routerBundlingVarious ways are available to bundle the app with minimum size using Webpack.I say separating the vendor libraries and components is the best way to reduce the bundling size.
  • The remaining two bundles are precisely due to code splitting.react-router can be used for Route based splitting out of box with WebpackWorkers From WebWeb workers and Service workers are most useful feature from web.
  • Both the workers have no access to DOM.Web Workers are use to do heavy operation in separate thread of browser and return result to the web app.Service workers are useful for caching the request.
