将eslint webpack插件添加到项目中以提供Typescript linting

显然 eslint-loader 不赞成,他们给 eslint-webpack-plugin typescript-eslint/parser 而不是 tslint ( 已弃用 .eslintrc.js .eslintrc 当使用分号时,应该会抛出一个错误。

export default class A {
  static yes = 'this is static'; // ";" <- should be invalidated by eslint
}

我的依赖关系是:

"@typescript-eslint/eslint-plugin": "^4.5.0",
"@typescript-eslint/parser": "^4.5.0",
"eslint": "^7.11.0",
"eslint-webpack-plugin": "^2.1.0",
"ts-loader": "^8.0.6",
"typescript": "^4.0.3",
"webpack": "^4.41.3",
"webpack-cli": "^3.3.10",
"webpack-dev-server": "^3.9.0"

@typescript-eslint/parser --> eslint-webpack-plugin --> #                         # 
      (uses eslint?)        (replaces eslint-loader)    #       webpack v4        #
                                                        #  w/ webpack-dev-server  #
       typescript         -->       ts-loader       --> #                         #
                                                        # # # # # # # # # # # # # #

旁注: webpack-dev-server 而不是 webpack-cli doesn't seem to work quite yet with webpack v5 .

我运行以启动服务器的命令: webpack-dev-server --hot --inline

./
├─── src
│    └─── index.ts
└─── dist
     ├─── bundle.js
     └─── index.html <- imports bundle.js

• webpack.config.js :

const path = require('path')
const ESLintPlugin = require('eslint-webpack-plugin')

module.exports = {
  mode: 'development',
  entry: './src/index.ts',
  devtool: 'inline-source-map',
  devServer: {
    contentBase: path.resolve(__dirname, 'dist')
    // publicPath: "/assets", // path of the served resources (js, img, fonts...)
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
    ],
  },
  plugins: [
    new ESLintPlugin({
      files: 'src/**/*.ts',
    })
  ],
  resolve: {
    extensions: [ '.tsx', '.ts', '.js' ],
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
}

• .eslintrc.js公司 :

module.exports = {
  root: true,
  env: {
    node: true,
  },
  parser: '@typescript-eslint/parser',
  extends: [
    'plugin:@typescript-eslint/recommended'
  ],
  parserOptions: {
    ecmaVersion: 2020,
    sourceType: 'module',
  },
  rules: {
    'semi': ['error', 'never'],
  },
  ignorePatterns: [ "dist/*" ],
}
