Development server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Why bother migrate?

Reasons to migrate:

• We can have all the new features and corrected bugs of previous versions
• The AOT builds will be noticeably faster ensuring a significant change in the compiler's performance.
• The Angular framework in the new version uses unique techniques and tools to debug its applications by themselves.
• With IVY we see an improvement in the build error. It gives less time for the builds to complete enabling all the error messages easier to read.
