为了将主要编译与测试编译分开,要设置哪些正确的打字稿编译器(tsc)选项?

What are the correct typescript compiler (tsc) options to set in order to separate main from test compilation?

我试图在我的项目中将主要源代码编译与测试源代码编译分开。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

我的目标是将个主要源代码编译成lib/main,将个测试源代码编译成lib/test .

我正在尝试将主编译和测试编译通用的所有编译器选项放在 tsconfig.json 中,然后使用命令行参数 tsc 来提供特定的选项到每个编译。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"
  }
}

package.json scripts 部分的片段如下(我拒绝 Gulp、Grunt 等,因为它太复杂,故意牺牲可移植性):

  "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,它们正确地出现在 lib/main 中。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.

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

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

让我感到困惑的是消息 'rootDir' is expected to contain all source files. 我正在尝试根据 lib/main 中的内容编译测试源。我不希望所有资源都在一个目录下。

tsconfig.json 选项和 tsc cli 选项的正确组合是什么来实现我的独立主编译和测试编译的目标?

错误:'rootDir' 应包含所有源文件。

rootDir 应该是所有 source/input 文件的根目录。 TS编译器是这样进行的:

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

src/main导入src/test个文件,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+)

Project references 可以解决您描述的所有问题:

  • rootDir将分别设置为src/mainsrc/test
  • src 文件夹未作为 lib 输出的一部分出现
  • src/main 无法导入 src/test(反之亦然)
结果项目结构:
|   tsconfig-base.json            // other config options go here
|   tsconfig.json                 // solution config containing references
|   
+---lib                           // output folder
|   +---main
|   |       mod.d.ts
|   |       mod.js
|   |       tsconfig.tsbuildinfo
|   |       
|   \---test
|           mod-test.js     
\---src
    +---main                      // referenced sub-project main 
    |       mod.ts
    |       tsconfig.json
    |       
    \---test                      // referenced sub-project test 
            mod-test.ts
            tsconfig.json
./tsconfig-base.json:
{
  "compilerOptions": {
    // just some sample values, set your own as needed
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "node",
    "strict": true,
    "esModuleInterop": true,
    // other compiler options
  }
}
./tsconfig.json:
{
  "files": [],
  "references": [
    {
      "path": "./src/main"
    },
    {
      "path": "./src/test"
    }
  ]
}
./src/main/mod.ts:
export const foo = "foo";
./src/main/tsconfig.json:
{
  "extends": "../../tsconfig-base.json",
  "compilerOptions": {
    "outDir": "../../lib/main",
    "composite": true // flag to signal referenced project      
  }
}
./src/test/mod-test.ts:
import { foo } from "../main/mod";

// use your test framework here
export function testMod() {
  if (foo !== "foo") throw new Error("foo expected.");
}

testMod()
./src/test/tsconfig.json:
{
  "extends": "../../tsconfig-base.json",
  "compilerOptions": {
    "outDir": "../../lib/test"
  },
  "references": [
    {
      "path": "../main" // test project depends on main
    }
  ]
}
您可以使用以下 scripts 构建和清理项目:
"scripts": {
    "build": "tsc -b -v",
    "clean": "tsc -b --clean"
},
