typescript - awesome-typescript-loader 仅加载/编译引用文件

Question

是否可以将 awesome-typescript-loader 或 webpack 或 tsc 配置为仅编译从条目(直接、间接)引用的文件？我想移植一个现有的应用程序，并希望能够编译我部分移植的代码，而一些未引用文件是不可编译的。

用过的工具

• awesome-typescript-loader:3.1.2，
• 网络包:2.3.3

webpack.js

var webpack = require('webpack');
module.exports = {
    entry: {
        'index': './Scripts/index.ts',
    },

    output: {
        path: helpers.root('dist'),
        filename: '[name].js'
    },

    resolve: {
        extensions: ['.ts', '.js']
    },
    module: {
        rules: [
            {
                test: /.ts$/,
                loader: 'awesome-typescript-loader'
            }
        ]
    }
}

配置

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "importHelpers": true,
    "typeRoots": [
      "node_modules/@types"
    ],
    "sourceMap": true,
    "lib": [
      "dom",
      "es5",
      "scripthost"
    ],
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "noImplicitAny": false,
    "suppressImplicitAnyIndexErrors": true
  },
  "exclude": [
    "node_modules"
  ]
}

Webpack 本身不包含任何未导入的文件。但是 TypeScript 似乎会检查项目中的每个文件，除非另有配置。来自tsconfig.json docs :

If the "files" and "include" are both left unspecified, the compiler defaults to including all TypeScript (.ts, .d.ts and .tsx) files in the containing directory and subdirectories except those excluded using the "exclude" property.

您可以将 files 选项设置为只包含您的入口点，它应该只检查您正在导入的文件。

"files": [
  "Scripts/index.ts"
]

据我测试，您还可以将它设置为一个空数组，这样默认情况下它不会检查任何文件，awesome-typescript-loader 会将文件传递给编译器正如预期的那样，它们仍将被检查。

"files": []
