Nx is a build system for JavaScript and TypeScript monorepos, with plugins extending it to any language. It helps you develop faster and keep CI fast as your codebase scales.
Challenges of monorepos
Section titled “Challenges of monorepos”Monorepos have many advantages and are especially useful for AI agents to have more context and tools to make cross-cutting changes. But as teams and codebases grow, monorepos are hard to scale:
- Slow builds and tests - Hundreds or thousands of tasks compete for CI resources.
- Complex task pipelines - Projects depend on each other, so tasks need to run in the right order, and that's hard to manage by hand.
- Flaky CI - Longer pipelines lead to random failures and inconsistent results between local and CI environments.
- Architectural erosion - Without clear boundaries, unwanted dependencies creep in and projects become tightly coupled.
What Nx does
Section titled “What Nx does”Nx reduces friction across your entire development cycle with intelligent caching, task orchestration, and deep understanding of your codebase structure.
Nx:
- Runs tasks fast - Caches results so you never rebuild the same code twice.
- Understands your codebase - Builds project and task graphs showing how everything connects.
- Orchestrates intelligently - Runs tasks in the right order, parallelizing when possible.
- Enforces boundaries - Module boundary rules prevent unwanted dependencies between projects.
- Handles flakiness - Automatically re-runs flaky tasks and self-heals CI failures.
Start small, grow as needed
Section titled “Start small, grow as needed”Nx is modular. Start with the CLI and add capabilities as your needs grow.
| Component | What It Does |
|---|---|
| Nx Core | Task runner with local caching. Works with any tech stack. |
| Nx Plugins | Technology-specific automation (generators, auto-configured projects and tasks, dependency detection). |
| Nx Cloud | Remote caching, affected commands, and self-healing CI. |
