Instalaltion

ng add @angular/material

Steps to use

1. Create a separate module for importing all matrial components

@NgModule({
  imports: [MatButtonModule],
  exports: [MatButtonModule],
})
export class MaterialDemoModule {}

2. Import the module in main module imports: [MaterialDemoModule]
3. Start using button module inside the code <button mat-button>Basic</button> NOTE To prevent errors on importing a material module, Restart the server after importing a new material module or try running npm install

fxLayout

• fxLayout="row" All elements are on a same row
• fxLayout="column" All elements are on different line
• fxLayout All elements are on diferent line (Column behaviour)

Angular Fire

• Allows connecting angular app to firebase with complete integration
• Uses Observable based data streams
• Install using ng add @angular/fire
• Inernaly manages token while sending/recieving requests from server

State management using RxjS

1. Execution of certain Event (button click)
2. State change even execition
3. Emitting an event using rxjs (Observable)
4. Listen to event (Subscription)
5. Update UI

Redux

• Central store to store something
• Consists of action, reducer, store
• We dispatch action to modify reducer state
• Installing
  • Automatic configuratin ng add @ngrx/store@latest
  • Manual npm install @ngrx/store --save

Steps to Implement redux

1. Create an initial state

const initialState = {
  isLoading: false,
};

2. Create a reducer

export function appReducer(state = initialState, action) {
  switch (action.type) {
    case 'START_LOADING':
      return {
        isLoading: true,
      };
    case 'STOP_LOADING':
      return {
        isLoading: false,
      };
    default:
      return state;
  }
}

3.Imprort it in app.module

import { StoreModule } from '@ngrx/store';
import { appReducer } from './app.reducer';
@NgModule({
  imports: [
    StoreModule.forRoot({ ui: appReducer }),
  ]
})

4. Use it in actual code
