为了将 main 与测试编译分开,需要设置哪些正确的 typescript 编译器 (tsc) 选项?

Mat*_*ams 6 typescript tsc

注意:如果您想查看完整的项目,此问题的公共 git 存储库位于https://github.com/matthewadams/ts-test 。

我正在尝试将项目中的主源编译与测试源编译分开。这是源目录结构:

src
  main
    ...typescript source files and possibly child directories with sources
  test
    unit
      ...unit test sources
    integration
      ...integration test sources

我的目标是仅将主要源代码lib/main编译到.lib/test

我试图将主编译和测试编译通用的所有编译器选项放入 中tsconfig.json,然后使用命令行参数来tsc提供特定于每个编译的选项。这是我目前的tsconfig.json:

{
  "compilerOptions": {
    "strict": true,
    "alwaysStrict": true,
    "diagnostics": true,
    "disableSizeLimit": true,
    "esModuleInterop": true,
    "extendedDiagnostics": true,
    "forceConsistentCasingInFileNames": true,
    "inlineSourceMap": true,
    "inlineSources": true,
    "listEmittedFiles": true,
    "listFiles": true,
    "module": "commonjs",
    "pretty": true,
    "target": "es2015"
  }
}

该节的一个片段package.json scripts如下(我拒绝 Gulp、Grunt 等,因为其复杂性,故意牺牲了可移植性):

  "scripts": {
    "transpile-main": "rm -rf lib/main && tsc --outDir lib/main --rootDir src/main -d --declarationDir lib/main",
    "transpile-test": "rm -rf lib/test && tsc --outDir lib/test --rootDir src/test --typeRoots lib/main",
    ...other scripts here...
  }

我可以毫无问题地编译主要源代码,并且它们lib/main正确显示。但是,当我编译测试源时,出现以下错误:

$ npm run transpile-test

> @matthewadams/ts-test@0.1.0-pre.0 transpile-test /Users/matthewadams/dev/me/ts-test
> rm -rf lib/test && tsc --outDir lib/test --rootDir src/test --typeRoots src/main

error TS6059: File '/Users/matthewadams/dev/me/ts-test/src/main/Nameable.ts' is not under 'rootDir' 'src/test'. 'rootDir' is expected to contain all source files.

让我感到困惑的是'rootDir' is expected to contain all source files. 我正在尝试根据lib/main. 我不希望所有源都在一个目录下。

为了实现单独的主编译和测试编译的目标,tsconfig.json选项和cli 选项的正确组合是什么?tsc

错误:“rootDir”应包含所有源文件。

rootDir预计是所有源/输入文件的根。TS 编译器的处理过程如下:

collect all input files ("files" / "include" / "exclude" / imports) 
  --> for each included input file
    --> chop off the "rootDir" from the input 
    --> prepend the "outDir"

文件src/test从 导入src/main,所以目前rootDir只能设置为src或以上。

解决方案:项目参考(TS 3.0+)

项目参考可以解决您描述的所有问题:

  • rootDir将分别设置为src/main或src/test
  • src文件夹不显示为lib输出的一部分
  • src/main无法导入src/test(反之亦然)
