基本安装
首先创建一个文件夹webpack-demo(名字自取)，然后在本地安装webpack，接着安装webpack-cli
npm init -y
npm install webpack webpack-cli --save-dev
然后在主文件夹下新建一个src和public子文件夹和webpack.config.js配置文件
- 在子文件夹public中新建index.html(此文件为入口文件模板，注意是模板)
- 在子文件夹src内新建main.js文件(此文件为项目入口主js文件)
webpack-demo
|- /public
|- index.html
|- /src
|- main.js
|- package-lock.json
|- package.json
|- webpack.config.js
index.html
webpack-demo
webpack-config.js
const path = require('path');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist')
}
};
安装webpack-dev-server,能够为你提供了一个简单的 web 服务器，并且能够实时重新加载等等
安装html-webpack-plugin和clean-webpack-plugin插件
npm install --save-dev webpack-dev-server
npm install --save-dev html-webpack-plugin
npm install --save-dev clean-webpack-plugin
package.json
{
"name": "development",
"version": "1.0.0",
"description": "",
"main": "webpack.config.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
+ "start": "webpack-dev-server --open --hot"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"html-webpack-plugin": "^2.29.0",
"webpack": "^3.0.0",
"webpack-cli": "^3.3.7",
"clean-webpack-plugin": "^3.0.0",
}
}
webpack.config.js
const path = require('path');
+ const HtmlWebpackPlugin = require('html-webpack-plugin');
+ const { CleanWebpackPlugin } = require('clean-webpack-plugin');
module.exports = {
entry: {
app: './src/main.js'
},
+ plugins: [
+ new HtmlWebpackPlugin({
+ template:'./public/index.html',
+ }),
+ new CleanWebpackPlugin(),
+ ],
+ devServer: {
+ contentBase: './dist',
+ port: 8000
+ },
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist')
}
};
为了从 JavaScript 模块中 import 一个 CSS 文件，你需要在 module 配置中 安装并添加 style-loader 和 css-loader
为了可以在项目中引入图片、字体文件，你需要在 module 配置中 安装并添加 file-loader
npm install --save-dev style-loader css-loader
npm install --save-dev file-loader
webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
plugins: [
new HtmlWebpackPlugin({
template:'./public/index.html',
}),
new CleanWebpackPlugin(),
],
devServer: {
contentBase: './dist',
port: 8000
},
+ module: {
+ rules: [
+ {
+ test: /\.css$/,
+ use: [
+ 'style-loader',
+ 'css-loader'
+ ]
+ },
+ {
+ test: /\.(jpg|png|svg|gif)$/,
+ use: [
+ 'file-loader'
+ ]
+ },
+ {
+ test: /\.(woff|woff2|eot|ttf|otf)$/,
+ use: [
+ 'file-loader'
+ ]
+ }
+ ]
+ }
}
由于好多好用的代码是ECMAScript 2015+ 版本的语法，浏览器无法识别，比如箭头函数等等，因此需要安装babel相关的模块和插件来转换为向后兼容的 JavaScript 语法(我只安装一下常用的，如果你使用其他的，需要自己安装和配置)
npm install --save-dev babel-loader
npm install --save-dev @babel/core @babel/cli @babel/preset-env
npm install --save-dev @babel/plugin-transform-arrow-functions
npm install --save-dev @babel/runtime @babel/plugin-transform-runtime
在主文件夹下面新建子文件夹babel.config.js
webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
plugins: [
new HtmlWebpackPlugin({
template:'./public/index.html',
}),
new CleanWebpackPlugin(),
],
devServer: {
contentBase: './dist',
port: 8000
},
module: {
rules: [
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
},
{
test: /\.(jpg|png|svg|gif)$/,
use: [
'file-loader'
]
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: [
'file-loader'
]
},
+ {
+ test: /\.js$/,
+ use: [
+ 'babel-loader'
+ ],
+ exclude: /node_modules/
+ },
]
}
}
babel.config.js
module.exports = function (api) {
api.cache(true);
const presets = [
'@babel/preset-env',
];
const plugins = [
'@babel/plugin-transform-arrow-functions',
'@babel/plugin-transform-runtime'
];
return {
presets,
plugins
};
}
Vue安装
安装vue相关的包
npm install vue --save
npm install --save-dev vue-loader vue-template-compiler
webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
+ const VueLoaderPlugin = require('vue-loader/lib/plugin');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
plugins: [
new HtmlWebpackPlugin({
template:'./public/index.html',
}),
new CleanWebpackPlugin(),
+ new VueLoaderPlugin(),
],
devServer: {
contentBase: './dist'，
port: 8000
},
module: {
rules: [
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
},
{
test: /\.(jpg|png|svg|gif)$/,
use: [
'file-loader'
]
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: [
'file-loader'
]
},
{
test: /\.js$/,
use: [
'babel-loader'
],
exclude: /node_modules/
},
+ {
+ test: /\.vue$/,
+ use: [
+ 'vue-loader'
+ ],
+ },
]
}
}
安装sass(sass是一个CSS预处理器，还挺好用，可以根据个人爱好安装)
npm install --save-dev sass-loader
npm install --save-dev node-sass
webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const VueLoaderPlugin = require('vue-loader/lib/plugin');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
plugins: [
new HtmlWebpackPlugin({
template:'./public/index.html',
}),
new CleanWebpackPlugin(),
new VueLoaderPlugin(),
],
devServer: {
contentBase: './dist'，
port: 8000
},
module: {
rules: [
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
},
{
test: /\.(jpg|png|svg|gif)$/,
use: [
'file-loader'
]
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: [
'file-loader'
]
},
{
test: /\.js$/,
use: [
'babel-loader'
],
exclude: /node_modules/
},
{
test: /\.vue$/,
use: [
'vue-loader'
],
},
+ {
+ test:/\.scss$/,
+ use:[
+ 'style-loader',
+ 'css-loader',
+ 'sass-loader'
+ ]
+ },
]
}
}
sass的使用如下:
- 引入外部样式使用
import '../css/test.scss' - 在.vue中使用
在子文件夹src下新建App.vue文件
main.js
import Vue from 'vue'
import App from './App.vue'
new Vue({
el: '#app',
render: h => h(App),
});
webpack-demo

|- index.html
|- /src
