use Facebook's create-react-app scaffolding to quickly build a react development environment (Ant.design,redux ...). ) The "scaffolding" in the programming field refers to a kind of tool that can quickly build a "skeleton" of the project scaffolding. For example, most react projects have src,public,webpack profiles, and so on, and the SRC directory contains components directories, and so on. Each time you create a new project, these fixed file directories are created manually. The role of scaff

Loader priority needs to be noted for two points, with the test configuration priority: Multiple loader are configured under the same test, and priority loader is placed after the configuration array, as for less processing: { test:/\.less$/, use : [ ' Style-loader ', ' css-loader ', ' postcss-loader ', ' Less-loader ' ] } Different test priority: such as the processing of JS files requires two test configuration, using Eslint-loader and

Node. js are not supported yet. Fortunately, babel already supports async transform, so we can introduce babel when using it. Before we start, we need to introduce the following package, which contains the async/await compilation file we need in preset-stage-3. Install the following package on both Browser and Node. js. $ npm install babel-core --save$ npm insta

launch stage, we do not recommend this. 1. the user needs to download these three files, which wastes bandwidth. 2. Compile the jsx file on the browser after the download is complete, which wastes time and resources. If you package and compile the project code in the development phase into a js file and then push it online, you can: 1. Reduce the number of HTTP requests to 1. 2, you do not need to waste time and resources on the client to compile the code, and directly run the compiled js Code

I. What is Webpack? What is his merit?First of all, for many just contact Webpack people, will certainly ask Webpack is what? What advantages does it have? Why should we use it? With these questions, let's summarize the following:Webpack is a front-end tool that allows modules to be loaded, preprocessed, packaged, and capable of grunt or gulp all basic functions. The advantages are as follows: Supports COMMONJS and AMD modules. Support for a number of module loader calls, can make t
