NOTE: Angular Material requires the BrowserAnimationsModule and
as per #5684 BrowserAnimationsModule should only be imported in your app/main module.

Example

Import NgxMatDrpModule module in your application module.

app.module.ts
`typescript
import { NgxMatDrpModule } from 'ngx-mat-daterange-picker';

@NgModule({
...,
imports: [..., NgxMatDrpModule, ...],
...
})
export class AppModule { }
`

Setup the NgxDrpOptions configuration required by the component and the handler function to receive the Range object on Date selection.

app.component.ts
`typescript
import { Component } from '@angular/core';
import { NgxDrpOptions, PresetItem, Range } from 'ngx-mat-daterange-picker';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {

range:Range = {fromDate:new Date(), toDate: new Date()};
options:NgxDrpOptions;
presets:Array = [];

ngOnInit() {
const today = new Date();
const fromMin = new Date(today.getFullYear(), today.getMonth()-2, 1);
const fromMax = new Date(today.getFullYear(), today.getMonth()+1, 0);
const toMin = new Date(today.getFullYear(), today.getMonth()-1, 1);
const toMax = new Date(today.getFullYear(), today.getMonth()+2, 0);

this.setupPresets();
this.options = {
presets: this.presets,
format: 'mediumDate',
range: {fromDate:today, toDate: today},
applyLabel: "Submit",
calendarOverlayConfig: {
shouldCloseOnBackdropClick: false,
hasBackDrop: false
}
// cancelLabel: "Cancel",
// excludeWeekends:true,
// fromMinMax: {fromDate:fromMin, toDate:fromMax},
// toMinMax: {fromDate:toMin, toDate:toMax}
};
}

// handler function that receives the updated date range object
updateRange(range: Range){
this.range = range;
}

// helper function to create initial presets
setupPresets() {

const backDate = (numOfDays) => {
const today = new Date();
return new Date(today.setDate(today.getDate() - numOfDays));
}

const today = new Date();
const yesterday = backDate(1);
const minus7 = backDate(7)
const minus30 = backDate(30);
const currMonthStart = new Date(today.getFullYear(), today.getMonth(), 1);
const currMonthEnd = new Date(today.getFullYear(), today.getMonth()+1, 0);
const lastMonthStart = new Date(today.getFullYear(), today.getMonth()-1, 1);
const lastMonthEnd = new Date(today.getFullYear(), today.getMonth(), 0);

this.presets = [
{presetLabel: "Yesterday", range:{ fromDate:yesterday, toDate:today }},
{presetLabel: "Last 7 Days", range:{ fromDate: minus7, toDate:today }},
{presetLabel: "Last 30 Days", range:{ fromDate: minus30, toDate:today }},
{presetLabel: "This Month", range:{ fromDate: currMonthStart, toDate:currMonthEnd }},
{presetLabel: "Last Month", range:{ fromDate: lastMonthStart, toDate:lastMonthEnd }}
]
}
}
`

Pass the reference of the new range selection handler function to selectedDateRangeChanged event emitter and the NgxDrpOptions options reference to the options input property.

`html

`

Reset the date using ViewChild reference:
`typescript
@ViewChild('dateRangePicker') dateRangePicker;

...

const today = new Date();
const resetRange = {fromDate: today, toDate: today};
this.dateRangePicker.resetDates(resetRange); // will trigger selectedDateRangeChanged

`
