之前配置的文件是这样的,他是一个很基础的版本
const path = require('path') const { CleanWebpackPlugin } = require('clean-webpack-plugin') const HtmlWebpackPlugin = require('html-webpack-plugin') module.exports = { entry: { app: './src/index.tsx', }, output: { path: path.resolve(__dirname, '../dist'), filename: '[name].[hash].js', }, resolve: { extensions: ['.ts', '.tsx', '.js', '.jsx'], }, module: { rules: [ { test: /\.(js|jsx)$/, loader: 'babel-loader', exclude: /node_modules/ }, { test: /\.(ts|tsx)$/, loader: 'ts-loader', exclude: /node_modules/ }, { test: /\.(css|scss)$/, exclude: /\.module\.scss$/, use: ['style-loader', 'css-loader', 'postcss-loader', 'sass-loader'], }, { test: /\.(jpe?g|png|gif|svg|woff|woff2|eot|ttf|otf)$/i, type: "asset/resource", } ], }, cache: { type: 'filesystem', // 可选配置 buildDependencies: { config: [__filename], // 当构建依赖的config文件(通过 require 依赖)内容发生变化时,缓存失效 }, name: 'development-cache', }, plugins: [ new HtmlWebpackPlugin({ title: 'REACT-TS', template: path.resolve(__dirname, '../index.html'), filename: 'index.html', }), new CleanWebpackPlugin(), ], }
当规则匹配时,只使用第一个匹配规则。
webpack原本的loader是将每个文件都过一遍,比如有一个js文件 rules中有10个loader,第一个是处理js文件的loader,当第一个loader处理完成后webpack不会自动跳出,而是会继续拿着这个js文件去尝试匹配剩下的9个loader,相当于没有break。 而oneOf就相当于这个break
我们这几个loader都是互斥的
