What is @lerna/run?
@lerna/run is a part of the Lerna monorepo management toolset. It allows you to run scripts or commands across multiple packages in a monorepo, making it easier to manage and automate tasks in a multi-package repository.
What are @lerna/run's main functionalities?
Run npm scripts in all packages
This command runs the 'test' script in all packages that contain it. It's useful for ensuring that all packages pass their tests before a release.
lerna run test
Run npm scripts in specific packages
This command runs the 'build' script only in the package named 'my-package'. This is useful for targeting specific packages for certain tasks.
lerna run build --scope my-package
Run npm scripts with parallel execution
This command runs the 'lint' script in all packages in parallel, which can speed up the process significantly compared to running them sequentially.
lerna run lint --parallel
Run npm scripts with a specific concurrency
This command runs the 'test' script in all packages but limits the number of concurrent executions to 4. This can help manage resource usage on your machine.
lerna run test --concurrency 4
