1. Installation:
Before using Angular CLI commands, ensure you have Node.js and npm installed. Then, install Angular CLI globally via npm:
npm install -g @angular/cli2. Generating Components:
Angular CLI simplifies component creation. Use the generate command with component or its shorthand c to create components:
ng generate component my-componentThis command creates a new component named my-component with its template, styles, and TypeScript file.
3. Generating Services:
To generate services, use the generate command with service or its shorthand s:
ng generate service my-serviceThis creates a service named my-service with a TypeScript file where you can define business logic.
4. Generating Modules:
To generate Angular modules, use the generate command with module or its shorthand m:
ng generate module my-moduleThis command creates a new module named my-module with its own TypeScript file.
5. Running the Application:
Use the ng serve command to run the Angular application locally:
ng serveThis starts a development server and serves the application on http://localhost:4200 by default.
6. Building for Production:
To build the application for production deployment, use the ng build command:
ng build --prodThis command compiles the application and generates optimized bundles for production.
7. Testing:
Angular CLI offers testing capabilities. Use ng test to run unit tests via Karma:
ng test8. Linting:
To lint your code using TSLint, use the lint command:
ng lintThis ensures your code adheres to best practices and style guidelines.
9. Configuration:
Angular CLI allows configuration via the angular.json file. Modify settings like output paths, assets, and more to suit your project requirements.
10. Additional Commands:
Explore more Angular CLI commands by running ng help or visit the official Angular CLI documentation.
Conclusion:
Mastering Angular CLI commands is crucial for efficient Angular development. With this guide, you’re equipped to leverage Angular CLI effectively, from project scaffolding to optimization and testing. Dive into your Angular projects with confidence using these powerful commands.
