问题描述

假设我将我的代码放在 src 下并在 spec 下进行测试:

Say I put my code under src and tests under spec:

+ spec
+ --- classA.spec.ts
+ src
+ --- classA.ts
+ --- classB.ts
+ --- index.ts
+ tsconfig.json

我只想将 src 转译到 dist 文件夹.由于 index.ts 是我的包的入口点,我的 tsconfig.json 看起来像这样:

I want to only transpile src to the dist folder. Since index.ts is the entry point of my package, my tsconfig.json look like this:

{
  "compileOptions": {
    "module": "commonjs"
    "outDir": "dist"
  },
  "files": {
    "src/index.ts",
    "typings/main.d.ts"
  }
}

但是,这个 tsconfig.json 不包含测试文件,所以我无法解析它们中的依赖项.

However, this tsconfig.json does not include the test files so I could not resolve dependencies in them.

另一方面,如果我将测试文件包含在 tsconfig.json 中,那么它们也会被转换为 dist 文件夹.

On the other hand, if I include the test files into tsconfig.json then they are also transpiled to dist folder.

我该如何解决这个问题?

How do I solve this problem?

推荐答案

我最终定义了多个配置文件并使用 extends 来简化它们.

I ended up defining multiple config files and use extends to simplify them.

假设我有两个文件:tsconfig.jsontsconfig.build.json

Say I have two files: tsconfig.json and tsconfig.build.json

// tsconfig.json
{
  ...
  "exclude": [...]
}

// tsconfig.build.json
{
  ...
  "files": [ "typings/index.d.ts", "src/index.ts" ]
}

这样,我可以很好地控制要构建的内容(使用 tsc -p tsconfig.build.json)以及 ts 语言服务 (IDE) 处理的内容.

This way, I can have fine control on what to build (using tsc -p tsconfig.build.json) and what the ts language service (IDE) handles.

更新:现在随着我的项目的增长,我最终拥有更多的配置文件.我使用了现在在 TypeScript 中可用的扩展"功能:

UPDATE: now as my projects grow, I ended up having more config files. I use the "extend" feature that is now available in TypeScript:

// tsconfig.base.json
{
  // your common settings. Mostly "compilerOptions".
  // Do not include "files" and "include" here,
  // let individual config handles that.
  // You can use "exclude" here, but with "include",
  // It's pretty much not necessary.
}

// tsconfig.json
{
  // This is used by `ts language service` and testing.
  // Includes source and test files.
  "extends": "./tsconfig.base.json",
  "atom": { ... },
  "compilerOptions": {
    // I set outDir to place all test build in one place,
    // and avoid accidentally running `tsc` littering test build to my `src` folder.
    "outDir": "out/spec"
  }
  "include": [ ... ]
}

// tsconfig.commonjs.json or tsconfig.systemjs.json or tsconfig.global.json etc
{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    // for some build this does not apply
    "declaration": true/false,
    "outDir": "dist/<cjs, sys, global, etc>",
    "sourceRoot": "..."
  },
  // Only point to typings and the start of your source, e.g. `src/index.ts`
  "files": [ ... ],
  "include": [ ... ]
 }
