What is this?
Angular CLI (`ng`) scaffolds projects, generates components/services, runs tests, and builds production bundles for MeanVerse frontends.
Why should you care?
CLI enforces consistent structure so enterprise Angular apps stay maintainable across squads.
See it live — copy this example
Paste into your MeanVerse project (Angular + Express + MongoDB), then run with ng serve / node / mongosh as noted.
# Create MeanVerse admin SPA
ng new meanverse-web --standalone --routing --style=scss
cd meanverse-web
ng generate component features/accounts/account-list --standalone
ng generate service core/api/account --skip-tests
ng serve --openWhat happened?
- ng new creates a standalone Angular app with routing.
- generate component adds files with correct imports.
- serve compiles and hot-reloads on port 4200.
Practice next
- Install CLI: npm install -g @angular/cli
- Run ng version and note Angular major version.
- Generate one component and one service.
- Add ng generate guard core/auth/auth --functional
- Run ng build and inspect dist/ output size.
Remember
CLI is the standard Angular workflow. Prefer standalone components in new MeanVerse code. generate keeps naming and folders consistent.
Healthcare portal scaffold
MeanVerse healthcare team needs patient-list and appointment modules fast.
Outcome: CLI generates boilerplate; devs focus on HIPAA-aware forms.
