Nx Has a Free Monorepo Build System with Project Graph Visualization

#javascript #webdev #devops #monorepo

Nx understands your codebase structure. It knows which projects depend on which, caches builds, and only runs what's affected by your changes.

Beyond Turborepo

Turborepo caches task outputs. Nx does that AND:

  • Visualizes your project dependency graph
  • Generates code with project-specific generators
  • Enforces module boundaries (prevent bad imports)
  • Distributes tasks across CI machines

What You Get for Free

Computation caching — same inputs → cached output
Affected commands — nx affected:test only tests projects affected by your changes
Project graph — nx graph opens a visual map of your entire codebase
Code generation — nx generate scaffolds projects, components, libraries
Module boundaries — lint rules that prevent unauthorized cross-project imports
Nx Cloud — distributed caching and task distribution (free tier: 500 hours/month)

Quick Start 

npx create-nx-workspace@latest my-org
Enter fullscreen mode Exit fullscreen mode

Or add to existing project:

npx nx@latest init
Enter fullscreen mode Exit fullscreen mode

The Project Graph 

nx graph
Enter fullscreen mode Exit fullscreen mode

Opens a browser with an interactive visualization of every project, library, and their dependencies. You can see exactly which projects are affected by a change.

Affected Commands 

nx affected -t build   # build only affected projects
nx affected -t test    # test only affected projects
nx affected -t lint    # lint only affected projects
Enter fullscreen mode Exit fullscreen mode

Change packages/utils? Nx knows which apps and libs depend on it and only rebuilds those.

Module Boundaries 

// .eslintrc.json
{
  "rules": {
    "@nx/enforce-module-boundaries": ["error", {
      "depConstraints": [
        { "sourceTag": "scope:app", "onlyDependOnLibsWithTags": ["scope:shared"] },
        { "sourceTag": "scope:api", "onlyDependOnLibsWithTags": ["scope:shared", "scope:api"] }
      ]
    }]
  }
}
Enter fullscreen mode Exit fullscreen mode

Frontend can't import backend code. Feature libs can't import app code. Enforced at lint time.

If your monorepo has >5 projects — Nx's project graph and affected commands save hours per week.
