webpack搭建vue3教程-高级篇

一.配置ES6转ES5:解决浏览器不支持ES6

1.安装依赖:

npm install @babel/core babel-loader @babel/preset-env -D

2.配置es6转es5的loader:

注意:配置也可以提出单独的文件配置:在项目根目录下创建babel.config.js或者babelrc.js具体配置查看官网教程

// webpack.config.js
const path = require('path');

module.exports = {
    mode: 'development',
    entry: './src/index.js',
    output: {
        filename: '[name].js',
        path: path.resolve(__dirname, 'dist')
    },
    module: {
        rules: [{
            test: /\.js$/,
            use: {
                loader: 'babel-loader',
                options: {
                    presets: ['@babel/preset-env']
                }
            }
        }]
    }

}

 

二.配置处理样式:

1.安装依赖:

npm install style-loader css-loader less less-loader -D

2.配置处理样式的loader:

// webpack.config.js
const path = require('path');

module.exports = {
    mode: 'development',
    entry: './src/index.js',
    output: {
        filename: '[name].js',
        path: path.resolve(__dirname, 'dist')
    },
    module: {
        rules: [{
                test: /\.js$/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env']
                    }
                }
            },
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    'css-loader'
                ]
            },
            {
                test: /\.less$/,
                use: [
                    'style-loader',
                    'css-loader',
                    'less-loader'
                ]
            }
        ]
    }

}

 

三.配置处理静态资源:

1.安装依赖:

npm install url-loader file-loader -D

2.配置静态资源的loader:
