Asked 8 months ago

New LinkNew LinkHi, I'm working on a monorepo project and need guidance on how to efficiently manage dependencies across multiple packages/modules using Lerna and npm. Can you provide a step-by-step approach for setting up and utilizing Lerna for dependency management?

To manage dependencies in a monorepo project using Lerna and npm, follow the steps below.

  1. First, initialize a monorepo using Lerna:
    npx lerna init
    Remember to choose the version control system you prefer (e.g., Git).
  2. Second, add packages or modules to your monorepo as separate directories.
  3. Third, define shared dependencies in the root `package.json`.
  4. Use Lerna's commands to add dependencies to individual packages:
    `lerna add`
    Remember to bootstrap your project, which ensures dependencies are linked correctly:
    `lerna bootstrap`
  5. Lastly, use Lerna to manage the versioning and publishing of your packages when ready.

If you have any issues, consider checking out the Lerna documentation here.
