NPM Workspaces Example

Find best way to create a build artifact from the production dependencies for only one workspace in the monorepo. Ideally, the installed dependencies are only in one node_modules directory, and located at the repo root.

Inspired by this SO question: https://stackoverflow.com/questions/70540116/how-do-i-install-dependencies-for-a-single-package-when-using-npm-workspaces/76376644#76376644

Examples:

• Remove node_modules from all locations:
  • npm run clean
• Produce production dependencies for only one workspace inside of the dist directory:
  • node build.js <pkg name>, for example node build.js foo.
• Alternative approach by moving package-lock.json and package.json files:
  • node prepare.js <pkg name>, for example node prepare.js foo. This effectively bypasses the npm tooling for workspaces.

Notes

• npm >= 9.7.2 is necessary to correctly use --omit=dev with workspaces.
  • @see npm/cli#6441
• --install-strategy=nested does not appear to work correctly with any npm version using workspaces.
