Web Client

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|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.

Warning!

All API (except signup and signin) need Header Authorization with user's token (use this format: Bearer <your JWT>). Token is valid for 1 hour.
Currently add token to client hub query string when calling MessageHub's methods.
