What is this?
Angular CLI (`ng`) scaffolds apps, generates components, and runs the dev server. Install it once globally or use npx.
Why should you care?
Without the CLI, project setup is slow and inconsistent across the team.
See it live — copy this example
Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.
npm install -g @angular/cli
ng version
# or: npx -y @angular/cli@19 versionWhat happened?
- ng version proves CLI and Node are working.
- Prefer a current LTS Node for new apps.
Practice next
- Install the CLI.
- Run ng version.
- Fix PATH if ng is not found.
- Try ng help generate.
- Update npm if installs fail.
Remember
CLI scaffolds and serves. Match CLI major to project. npx avoids global drift.
Team onboarding
New hire clones AngularVerse.
Outcome: Same CLI commands work on day one.
