Question

是否可以配置awesome-typescript-loader或webpack或tsc来编译从条目引用（直接，间接）的文件？我想移植现有的应用程序，并希望能够编译我的部分移植代码，而一些未引用的文件不可编译。

使用过的工具

awesome-typescript-loader：3.1.2，
webpack：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'
            }
        ]
    }
}

tsconfig

{
  "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"
  ]
}

错误消息（来自index.ts未引用的文件）

Webpack本身不包含任何未导入的文件。但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：

如果＆＃34;文件＆＃34;和＆＃34;包括＆＃34;如果未指定，编译器默认包含所有包含目录和子目录中的TypeScript（.ts，.d.ts和.tsx）文件，但使用＆＃34; exclude＆＃34;排除的文件除外。属性。

您可以将files选项设置为仅包含您的入口点，并且只应检查您要导入的文件。

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

据我测试过，您也可以将其设置为空数组，因此默认情况下它不会检查任何文件，awesome-typescript-loader会按预期将文件传递给编译器，他们仍然会被检查。

"files": []

awesome-typescript-loader只加载/编译refrenced文件
