Usage

Initialization

git clone https://github.com/hanpama/typescript-composite-lerna
cd typescript-composite-lerna
npm run boostrap
npm run watch

npm run bootstrap

  • installs the project dependencies (in /package.json)
  • links each packages
  • and builds the project with npm run build (tsc --build packages/tsconfig.project.json)

npm run watch

  • run tsc project build mode with --watch flag (tsc --build --watch packages/tsconfig.project.json)

You can watch the entire project with a single tsc running.

Updating tsconfig.package.json

npm run update:tsconfig.json

Each package has its tsconfig.package.json file for individual build. To integrate those building process into project, we need references field listing its build dependencies.

// GENERATED by scripts/update-package-tsconfig.ts
{
  "extends": "../../tsconfig.base.json",
  "compilerOptions": {
    "outDir": "./lib",
    "rootDir": "./src",
    "composite": true
  },
  "references": [
    {
      "path": "../foo/tsconfig.package.json"
    },
    {
      "path": "../bar/tsconfig.package.json"
    }
  ],
  "include": [
    "src"
  ],
  "exclude": [
    "tests",
    "lib"
  ]
}

update:tsconfig.json is a script which resolves and updates those dependencies.
