lerna-yarn-ts-demo

This is a demo project to demonstrate how to use lerna + yarn + TypeScript together.

Key takeaways

• If a devDependency is installed into root package.json (where lerna is installed), then it shouldn't be installed to individual packages any more.
  • Because root level devDependency is also available to individual packages.
  • Sample dependency: yarn-upgrade-all, gts, typescript...etc.
• If you want to publish a public scoped package to NPM, add "publishConfig": {"access": "public"} to that package's package.json file.
• You need to NPM login as @scope user in order to publish @scope/xxx.
  • Or you create an org named scope using your NPM account.
• Each package could has its own configuration file such as tsconfig.json & .eslintrc.json, and this configuration file should extend root level configuration files (if they exist).

Lint

yarn lint

test

yarn jest

Add local dependencies

# add @tylerlong/test-pkg1 as dependency to packages/tests
yarn lerna add @tylerlong/test-pkg1 packages/tests
# add @tylerlong/test-pkg2 as dependency to packages/tests
yarn lerna add @tylerlong/test-pkg2 packages/tests

Upgrade all dependencies

yarn upgrade-all

Compile

lerna exec tsc --ignore=@tylerlong/tests
