• quickstart monorepo example for react projects and vanillajs projects

• tech-stack

  • react 17
  • typescript 4
  • monorepo
    • A mix of TypeScript and Javascript packages
    • npm workspaces only, no lerna
    • yarn workspace should work too, but not tested here
  • webpack 5
    • webpack config shared at top level with webpack-merge
    • hot reloading with react-refresh-webpack-plugin

  • jest for testing
  • styling
    • support scss, css

  • package-a: simple utils
  • packages
    • sample-app: simple react app

• npm 7 workspaces limitations

  • no equivalent of yarn workspaces run cmd
  • no equivalent of yarn workspace workspaceName cmd

• The main field of all package.jsons points to src for easier development

  • imports in vscode ide use main for code jumping
  • imports in webpack use module

• If you want to publish a package, it's better to point main to dist in the package.json

• APP_ENV environment variable

  • if no value is set, building es6 and ts is supported, but not react
