从NPM包中导出多个模块 [英] Export multiple modules from NPM package

问题描述

我有一个使用Node和Typescript的相当大的项目A.在项目A中，我有很多不同的模块，希望在另一个项目B中重用.

I have a rather large project A using Node and Typescript. In project A I have a lot of different modules that I would like to reuse in another project B.

因此，我使用以下tsconfig.json构建了项目A:

Therefore I have built the project A with this tsconfig.json:

{
    "compilerOptions": {
        "target": "es2017",
        "module": "commonjs",
        "declaration": true,
        "outDir": "./dist",
        "sourceMap": true,
        "strict": true,
        "noImplicitAny": true,
        "strictNullChecks": true,
        "typeRoots": ["./node_modules/@types", "./modules/@types"]
    },
    "exclude": ["node_modules"]
}

因此，所有文件都以这种方式内置到/dist文件夹中:

So all the files are built into the /dist folder this way:

• dist
  • moduleA.js
  • moduleA.map
  • moduleA.d.ts
  • moduleB.js
  • moduleB.map
  • moduleB.d.ts
  • ....
  • dist
    • moduleA.js
    • moduleA.map
    • moduleA.d.ts
    • moduleB.js
    • moduleB.map
    • moduleB.d.ts
    • ....

    要在另一个项目中使用这些moduleA和moduleB，请将以下内容添加到Project A中的package.json中:

    To use these moduleA and moduleB in another project, I add the following to the package.json in Project A:

        "name": "projectA",
        "version": "1.0.0",
        "description": "...",
        "main": "dist/moduleA.js",
        "typings": "dist/moduleA.d.ts",
    

    我使用纱线工作区作为项目B中的程序包访问项目A.但是问题是，在新项目B中使用import {ModuleA} from 'projectA'时，我只能访问模块A?那么如何从ProjectA访问更多模块?

    I use yarn workspaces to access Project A as a package in Project B. But problem is that I can only access moduleA, when using import {ModuleA} from 'projectA' in my new project B? So how can I access more modules from ProjectA?

    推荐答案

    将所有出口合并为一个index.ts会为您解决这个问题吗?

    Would simply consolidating all exports in one index.ts do the trick for you?

    package.json(projectA):

    package.json (projectA):

    {
      "main": "dist/index.js",
      "typings": "dist/index.d.ts",
      ...
    }
    

    index.ts(projectA):

    index.ts (projectA):

    // Adjust the relative import paths 
    // and identifiers to your structure
    export { ModuleA } from "./moduleA";
    export { ModuleB } from "./moduleB";
    

    projectB中的某些模块:

    Some module in projectB:

    import {ModuleA, ModuleB} from 'projectA'
