Detailed explanation of WebPack configuration methods in the Vue-CLI scaffolding

What is WebPack

WebPack is a Module Bundler (module package tool), so-called module is to use some static resources in the usual front-end development, such as JavaScript, CSS , Pictures, etc., WebPack refer to the module

WebPack supports AMD and Commonjs, and other module systems, and compatible with multiple JS writing specifications, can handle the relationship between modules. Therefore, it has more powerful JS modular functions that can be unified and packaged on static resources. Introduction to this picture in the official website:


It can replace GRUNT and GULP in many places because it can compile pack CSS, do CSS pre-processing, compile the js dialect, package pictures, code compression, etc. So after I arrived with WebPack, I didn’t want to use Gulp

Summary as follows:

Pair of Commonjs The symptoms of AMD and ES6 are compatible;

    Support package for JS, CSS, pictures and other resource files;
  • Series module loader and plug-in mechanism make it better Flexibility and scalability, such as support for CoffeeScript, ES6;
  • There are independent configuration files WebPack.config.js;
  • can cut the code into different chunks, implement on-demand Loading, reducing initialization time;
  • Supports SourceURLS and Sourcemaps, easy to debug;
  • Most of the PLUGIN interface, mostly internal plugins, flexible in use;
  • WebPack Use asynchronous IO and have multi-level cache. This makes WEBPACK is very fast and more accelerated on incremental compilation;
  • WebPack is mainly used in Vue and React, in fact it is very like Browserify, but puts the application to multiple files . If there is a plurality of pages in a single page, then the user only downloads the code of the corresponding page. When he accesses another page, they don’t need to re-download the universal code.

  • Based on my project

The basic directory structure of the Vue Webpack configuration file is as follows:

config – dev.env.js // dev environment variable configuration ├── INDEX.JS / / DEV and PROD environment Some basic configuration └ – Prod.Env.js // PROD environment variable configuration build ─ ─ build.js Script of // NPM Run Build ├─- Check-Versions.js // Check NPM and NODE version ├─ Logo.png ├─ utils.js // Some tool methods are used to generate CssLoader and StyleLoader Configuration ├─- Vue-loader.conf.js // Vueloader configuration information ├── WebPack.base.conf.js // // // dev environment Configuration └─- WebPack.Prod.conf.js // Configuration of the Prod Environment

Config folder file detailed
The files in Config are actually served in build, most of which define a variable export going out

  When the development environment configuration of dev.env.js is transferred, the production environment configuration of Prod.Env.js is called when published  

Use strictModule.exports = {node_env: ‘”production”‘}
