如果我们有合适的工具,开发就会变得更容易。在这篇文章中,我将讨论一些流行的webpack插件。
以上输出很难阅读和理解。此外,信息没有很好地格式化和呈现。
这里webpack仪表盘的图片有一个更好的视觉输出。通过在cmd中键入命令来安装它。
npm install --save-dev webpack-dashboard
# or
$ yarn add --dev webpack-dashboard
注:webpack-dashboard@^3.0.0
需要node8+
或以上。以前的版本只支持node6。
现在,我们需要在·webpack.config.js·中导入这个插件,并添加到plugins数组中。
//webpack.config.js
const path = require('path');
const webpackDashboard = require('webpack-dashboard/plugin');
module.exports = {
entry: './src/index.js',
output: {
path: path.join(__dirname, '/dist'),
filename: 'bundle.js'
},
devServer: {
port: 8080
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.css$/,
use: [ 'style-loader', 'css-loader' ]
}
]
},
plugins:[
new webpackDashboard() // add
]
}
还需要在package.json
中修改你的脚本。只需要在每个脚本之前附加webpack-dashboard。
"scripts": {
"start": "webpack-dashboard -- webpack serve --mode development --open --hot",
"build": "webpack-dashboard -- webpack --mode production"
}
运行应用程序,您将看到一个非常棒的构建过程输出。😍
terser webpack
插件用于压缩你的JavaScript包的大小
以供生产
使用。这个插件还支持ES6+
JavaScript语法。
注意:Terser webpack插件默认是webpack 5自带的
。
使用下面的命令安装这个插件:
npm install --save-dev terser-webpack-plugin
然后导入并添加这个插件到你的webpack.config.js中:
//webpack.config.js
const path = require('path');
const webpackDashboard = require('webpack-dashboard/plugin');
const TerserPlugin = require("terser-webpack-plugin");
module.exports = {
entry: './src/index.js',
output: {
path: path.join(__dirname, '/dist'),
filename: 'bundle.js'
},
optimization: {
minimize: true,
minimizer: [new TerserPlugin()],
},
devServer: {
port: 8080
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.css$/,
use: [ 'style-loader', 'css-loader' ]
}
]
},
plugins:[
new webpackDashboard()
]
}
这个插件将搜索你项目中的所有CSS文件
,并优化/压缩CSS
。
npm install --save-dev optimize-css-assets-webpack-plugin mini-css-extract-plugin css-loader
webpack.config.js.
:
//webpack.config.js
const path = require('path');
const TerserPlugin = require("terser-webpack-plugin");
const webpackDashboard = require('webpack-dashboard/plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
entry: './src/index.js',
output: {
path: path.join(__dirname, '/dist'),
filename: 'bundle.js'
},
optimization: {
minimize: true,
minimizer: [new TerserPlugin(), new MiniCssExtractPlugin()],
},
devServer: {
port: 8080
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.css$/i,
use: [MiniCssExtractPlugin.loader, 'css-loader'],
},
]
},
plugins:[
new webpackDashboard(),
new MiniCssExtractPlugin(),
new OptimizeCssAssetsPlugin({
assetNameRegExp: /\.optimize\.css$/g,
cssProcessor: require('cssnano'),
cssProcessorPluginOptions: {
preset: ['default', { discardComments: { removeAll: true } }],
},
canPrint: true
})
]
}
HTML webpack插件,用于生成HTML文件,用JavaScript代码注入脚本标签。这个插件用于开发和生产构建。
使用以下方法安装此插件:
npm install --save-dev html-webpack-plugin
webpack.config.js
:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const TerserPlugin = require("terser-webpack-plugin");
const webpackDashboard = require('webpack-dashboard/plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
entry: './src/index.js',
output: {
path: path.join(__dirname, '/dist'),
filename: 'bundle.js'
},
optimization: {
minimize: true,
minimizer: [new TerserPlugin(), new MiniCssExtractPlugin()],
},
devServer: {
port: 8080
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.css$/i,
use: [MiniCssExtractPlugin.loader, 'css-loader'],
},
]
},
plugins:[
new HtmlWebpackPlugin(
Object.assign(
{},
{
inject: true,
template: path.join(__dirname,'/src/index.html')
},
// Only for production
process.env.NODE_ENV === "production" ? {
minify: {
removeComments: true,
collapseWhitespace: true,
removeRedundantAttributes: true,
useShortDoctype: true,
removeEmptyAttributes: true,
removeStyleLinkTypeAttributes: true,
keepClosingSlash: true,
minifyJS: true,
minifyCSS: true,
minifyURLs: true
}
} : undefined
)
),
new webpackDashboard(),
new MiniCssExtractPlugin(),
new OptimizeCssAssetsPlugin({
assetNameRegExp: /\.optimize\.css$/g,
cssProcessor: require('cssnano'),
cssProcessorPluginOptions: {
preset: ['default', { discardComments: { removeAll: true } }],
},
canPrint: true
})
]
}
Clean webpack
插件用于清理/删除你的构建文件夹
。它还将在每次成功重建后删除所有未使用的webpack assets。
这个插件将帮助减少包的大小,删除不需要的文件和assets文件。
使用以下方法安装此插件:
npm install --save-dev clean-webpack-plugin
webpack.config.js:
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const TerserPlugin = require("terser-webpack-plugin");
const webpackDashboard = require("webpack-dashboard/plugin");
const OptimizeCssAssetsPlugin = require("optimize-css-assets-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
module.exports = {
entry: "./src/index.js",
output: {
path: path.join(__dirname, "/dist"),
filename: "bundle.js",
},
optimization: {
minimize: true,
minimizer: [new TerserPlugin(), new MiniCssExtractPlugin()],
},
devServer: {
port: 8080,
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: "babel-loader",
},
{
test: /\.css$/i,
use: [MiniCssExtractPlugin.loader, "css-loader"],
},
],
},
plugins: [
new HtmlWebpackPlugin(
Object.assign(
{},
{
inject: true,
template: path.join(__dirname, "/src/index.html"),
},
// Only for production
process.env.NODE_ENV === "production"
? {
minify: {
removeComments: true,
collapseWhitespace: true,
removeRedundantAttributes: true,
useShortDoctype: true,
removeEmptyAttributes: true,
removeStyleLinkTypeAttributes: true,
keepClosingSlash: true,
minifyJS: true,
minifyCSS: true,
minifyURLs: true,
},
}
: undefined
)
),
new webpackDashboard(),
new MiniCssExtractPlugin(),
new OptimizeCssAssetsPlugin({
assetNameRegExp: /\.optimize\.css$/g,
cssProcessor: require("cssnano"),
cssProcessorPluginOptions: {
preset: ["default", { discardComments: { removeAll: true } }],
},
canPrint: true,
}),
new CleanWebpackPlugin({
// Use !negative patterns to exclude files
// default: []
cleanAfterEveryBuildPatterns: ["static*.*", "!static1.js"],
// Write Logs to Console
// (Always enabled when dry is true)
// default: false
verbose: true,
}),
],
};
在运行npm run build之后,你可以看到 dist文件夹下的所有文件都会被删除,之后只会发出必需的文件,temp.js也会被删除,因为它在任何文件中都没有引用。
