Nx
Overview
Nx is a build system for monorepos. It provides computation caching (local + remote), task orchestration, dependency graph, code generators, and affected commands. Works with React, Angular, Node.js, Next.js, and any language.
Instructions
Step 1: Create Workspace
npx create-nx-workspace@latest my-org --preset=ts
cd my-org
Step 2: Add Projects
nx g @nx/react:app my-app
nx g @nx/js:lib shared-utils
nx g @nx/node:app api
Step 3: Run Tasks
nx serve my-app
nx build api
nx test shared-utils
nx affected -t test # only what changed
nx run-many -t build test # everything
Step 4: nx.json Configuration
// nx.json — Workspace configuration
{
"targetDefaults": {
"build": { "dependsOn": ["^build"], "cache": true },
"test": { "cache": true },
"lint": { "cache": true }
}
}
Guidelines
- Nx caches task results — second run is instant if inputs haven't changed.
- Use nx affected in CI to only build/test what changed in a PR.
- Nx Cloud provides remote caching — share cache across team/CI.
- Nx works without plugins too — add it to any repo with npx nx init.
