babel transpiler

Recently, because of working relationships, I have been doing the development of node. js, learning the KOA Framework, ORM Framework Sequelize, and the configuration of swagger documents. However, because the swagger document uses a ES6 decorator (called Annotations in Java) recently, node. JS cannot compile the project, so you need to convert ES6 using Babel. Because this article is to write, how to configure the use of the

lot of loaders that make it a little mean to do many of the same things. You can also get to know the browserify, but in my opinion, must be familiar with Webpack after to engage in it, I trust the wise son told me, Systemjs in this field is also a serious competitor, but I still useless it, its documentation makes me want to read. Its package Manager JSPM is fascinating, allowing you to pull the required modules from different sources, including NPM, but I'm a little concerned about the combin

use of methods such as Render, Componentdidmount, Componentwillunmount, and so on, like react and lifecycle hooks, reduces the difficulty of the front-end engineers accustomed to using react development.Full lifecycle Hooks View the:=> Ink lifecycleOf course, ink also provides properties such as state, props.In the process of using, starting an INK project is not easy, the official documentation is limited, fortunately the author provides a generator, here gives the address:=> Ink-generatorFina

exact equality operator considers Nan not equal to itself.Here a lot of students will say, now a lot of browsers do not support ES6 syntax, use is also equal to white, then here I am in the introduction of something. It is called Babel;First we install it through NPM.So we can use the Babel command, of course, you can also change the file root directory to inject it into the dependencyThen install a

developers, each of which can help you improve your workflow and make it more efficient. Next, let's get started! 1. Babel The first is the Babel plug-in. The plug-in adds appropriate syntax highlighting to ES6/2015 and React JSX code. After installing the plug-in, the first thing you need to do is set the default syntax to. es6,. jsx, And even. js files. However, if you work on ES3/5 and do not want to us

projects as project files and packages them. In actual development, we need to install a lot of NPM extension libraries, which contain a large number of files that do not need to be packaged. for example, lodash contains thousands of files, however, we only need to use a very small part of it. In addition, during development, we often need to install babal, eslient, webpack, and grunt to wait for the development tool, mini-program development tools will also package the source code of these too

So found the Webpack-utf8-bom this plugin to solve the problem smoothly.The rest of the information is in the notes.With the introduction, loading, and packaging of webpack resources, is everything so natural that I can still not like it?Package.json seems a bit incomplete, not all just press Webpack.config.js to find it.{"name": "src", "version": "1.0.0", "description": "$", "main": "Webpack.config.js", "dependencies": {"babel-c Ore ":" ^6.1

Recent project preparation using react as the front end, the main first comparison of fire, the second relatively small. Take the time to study first.First download the resource file: less than 50KB after compression, is quite small oh.Where: react.js is the core library of React, react-dom.js is to provide DOM-related features, react-dom-server.js is the server-side rendering of the DOM function, React-with-addons is some plug-in features.OK, let's leave it to the server and addons, start with

ES6, full name ECMAScript6 (aka es2015). What is ECMAScript? What do we often say about JavaScript and how it's connected?Nanyi Teacher has a sentence to describe the more accurate: "ECMAScript is the international standard of JavaScript language, JavaScript is the implementation of ECMAScript." JS has several large versions, now used more is the ES3,ES5. And last year, ES6 's standards were introduced, and for every front-end developer, embracing the new standards was inevitable, so from now on

After installing the plug-in, the first thing you need to do is set the default syntax to. es6,. jsx, And even. js files.

The principle is that the specific third-party NPM package module is built in advance, and then introduced through the page.

One of the stars in the war is to let the other party learn a language, that is, let the other side steppir to. Programming languages also have a similar power
