Lerna is a build system and CLI for managing, versioning, and publishing multiple JavaScript/TypeScript packages from a single monorepository. Since v6 it delegates task scheduling to Nx, providing computation caching, parallel task execution, and distributed task execution across machines.
Use cases
- manage a javascript monorepo with multiple packages
- publish multiple npm packages from one repository
- run build and test tasks across packages in the right order
- cache build results so the same code is never rebuilt twice
- run tasks only for projects affected by a PR
- version and tag packages automatically with semantic version bumps
- speed up CI by distributing tasks across multiple machines
When to choose
- you maintain many JavaScript/TypeScript packages in a single repository
- you need automated version bumping and npm publishing workflows
- you want fast, cached, order-aware task execution powered by Nx
- you want to run commands only against changed or affected packages
When to avoid
- you have a single-package repository with no monorepo needs
- you rely on another monorepo tool like Nx directly, Turborepo, or pnpm workspaces alone
- you need language support beyond the JavaScript/TypeScript ecosystem
