| # learn_webpack | ||
| webpack 系列学习 | ||
|
|
||
| ## 打包 src 下的 index.js index.css 到 dist/bundle.js | ||
|
|
||
| ### 配置 | ||
|
|
||
| package.json | ||
|
|
||
| ```json | ||
| { | ||
| "scripts": { | ||
| "dev": "cross-env NODE_ENV=development webpack", // 开发环境 | ||
| "build": "cross-env NODE_ENV=production webpack" // 生产环境 | ||
| }, | ||
| "dependencies": { | ||
| "cross-env": "^6.0.3", | ||
| "css-loader": "^3.2.0", | ||
| "rimraf": "^3.0.0", | ||
| "webpack": "^4.41.2" | ||
| }, | ||
| "devDependencies": { | ||
| "webpack-cli": "^3.3.10" | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| webpack.config.js | ||
|
|
||
| ```js | ||
| const path = require('path'); | ||
| const rimraf = require('rimraf'); | ||
|
|
||
| // 删除 dist 目录 | ||
| rimraf.sync('dist'); | ||
|
|
||
| // webpack 配置 | ||
| module.exports = { | ||
| entry: './src/index', | ||
| mode: process.env.NODE_ENV, | ||
| output: { | ||
| filename: 'bundle.js', | ||
| path: path.resolve(__dirname, 'dist') | ||
| } | ||
| }; | ||
| ``` | ||
|
|
||
| src/index.js | ||
|
|
||
| ```js | ||
| const css = require('css-loader!./index.css'); | ||
| const a = 100; | ||
| console.log(a, css); | ||
| ``` | ||
|
|
||
| src/index.css | ||
|
|
||
| ```css | ||
| body { | ||
| width: 100%; | ||
| height: 100vh; | ||
| background-color: orange; | ||
| } | ||
| ``` | ||
|
|
||
| 使用 webpack-chain 修改配置 | ||
|
|
||
| ```js | ||
| const path = require('path'); | ||
| const rimraf = require('rimraf'); | ||
| const Config = require('webpack-chain'); | ||
| const config = new Config(); | ||
| const resolve = (src) => { | ||
| return path.join(process.cwd(), src) | ||
| } | ||
|
|
||
| // 删除 dist 目录 | ||
| rimraf.sync('dist') | ||
|
|
||
| config | ||
| // 入口 | ||
| .entry('src/index') | ||
| .add(resolve('src/index.js')) | ||
| .end() | ||
| // 模式 | ||
| // .mode(process.env.NODE_ENV) 等价下面 | ||
| .set('mode', process.env.NODE_ENV) | ||
| // 出口 | ||
| .output | ||
| .path(resolve('dist')) | ||
| .filename('[name].bundle.js'); | ||
|
|
||
| config.module | ||
| .rule('css') | ||
| .test(/\.css$/) | ||
| .use('css') | ||
| .loader('css-loader') | ||
|
|
||
| module.exports = config.toConfig(); | ||
