标签：配置 ts js webpack html 本地 new loader
1.需要安装的依赖
"dependencies": {
"html-webpack-plugin": "^5.5.0",
"ts-loader": "^9.2.6",
"ts-node": "^10.4.0",
"tslib": "^2.3.1",
"typescript": "^4.4.4",
"webpack": "^5.60.0",
"webpack-cli": "^4.9.1",
"webpack-dev-server": "^4.4.0"
},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "webpack",
"serve": "webpack serve"
},
2. webpack.config.js配置
const path = require('path').resolve(__dirname, './dist')
const htmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
// 需要添加模式,否则报错
mode: 'development',
// 完整相对路径
entry: './src/main.ts',
output: {
path,
filename: 'bundle.js'
},
resolve: {
// 只匹配ts会导致 无法正常运行js代码
extensions: ['.ts', '.js', '.cjs', '.json']
},
// 使用ts-loader
module: {
// 规则是一个数组
rules: [
{
test: /\.ts$/,
loader: 'ts-loader'
}
]
},
plugins: [
// 插件需要 通过new 进行使用
new htmlWebpackPlugin({
template: './index.html'
})
]
}
3.index.html 模板文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>ts Learn</title>
<script src="./src/main.ts"></script>
</head>
<body></body>
</html>
5. 文件结构
6.遇到问题
扩展规则少了 js文件的匹配
Module not found: Error: Can't resolve './log' in '/Users/zdz/Desktop/LearnCode/learn-code/Ts/node_modules/webpack/hot'
htmlWebpackPlugin需要通过new构造使用
ypeError: Class constructor HtmlWebpackPlugin cannot be invoked without 'new'
