typescript - HtmlWebpackPlugin 不适用于 typescript 应用程序

Question

这是我的 webpack.config.js

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
   entry: './src/index.tsx',
   output: {
      path: path.resolve(__dirname, "build"),
      filename: 'bundle.js'
   },
   module: {
      rules: [
         {
            test: /\.tsx?$/,
            loader: "awesome-typescript-loader"
         }
      ]
   },
   plugins: [
      new HtmlWebpackPlugin({
         template: "./index.html"
      })
   ]
}

这是我的 package.json

{
  "name": "react-ts-todo",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "start": "webpack-dev-server --mode development"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^16.3.0",
    "react-dom": "^16.3.0"
  },
  "devDependencies": {
    "@types/react": "^16.1.0",
    "@types/react-dom": "^16.0.4",
    "awesome-typescript-loader": "^4.0.1",
    "html-webpack-plugin": "^3.1.0",
    "typescript": "^2.8.1",
    "webpack": "^4.4.1",
    "webpack-cli": "^2.0.13",
    "webpack-dev-server": "^3.1.1"
  }
}

我可以使用 nom start 轻松启动我的 webpack 服务器，但是当我更改我的文件并尝试刷新时。我的 webpack 开发服务器因错误而崩溃

我用谷歌搜索并找到了这个

https://github.com/s-panferov/awesome-typescript-loader/issues/541

但这对我来说没有明确可行的解决方案。

好的。我找到了答案 here .我们需要将很棒的 typescript 加载器升级到

"awesome-typescript-loader": "^5.0.0-1"

以下 package.json 工作正常。

{
  "name": "react-ts-todo",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "start": "webpack-dev-server --mode development"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^16.3.0",
    "react-dom": "^16.3.0"
  },
  "devDependencies": {
    "@types/react": "^16.1.0",
    "@types/react-dom": "^16.0.4",
    "awesome-typescript-loader": "^5.0.0-1",
    "html-webpack-plugin": "^3.1.0",
    "typescript": "^2.8.1",
    "webpack": "^4.4.1",
    "webpack-cli": "^2.0.13",
    "webpack-dev-server": "^3.1.1"
  }
}
