Ngx-Bootstrap DateRange Picker And Date Picker

Introduction

 

In this article we are going to learn the use of Ngx-Bootstrap DateRange Picker and Date Picker in Angular 8.

 

Ngx-Bootstrap has released a package of open-source tools which is native Angular directives for Bootstrap 3 and 4. It contains all core components powered by Angular. In this article we will learn about DatePicker component which is a cool feature of Ngx-bootstrap.

 

Prerequisites

• Basic knowledge of Angular
• Visual Studio Code must be installed
• Angular CLI must be installed
• Node JS must be installed

Step 1

 

Let's create a new Angular project using the following NPM command,

ng new datepicker

Step 2

 

Now, let's create a new component by using the following command,

ng g c ngx-bootstrap-datepicker

Step 3

 

Install ngx-bootstrap from npm by using the folowing command.

npm install ngx-bootstrap --save

Or,

ng add ngx-bootstrap --component datepicker

Step 4

 

Now let's add bootstrap styles in our index.html file .

 

For Bootstrap 3,

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

For Bootstrap 4,

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">

Step 5

 

Let add the template in our ngx-bootstrap-datepicker.component.html.

<div class="card">
  <div class="card-body pb-0">
    <h4 style="text-align: center;">Example of Date Picker and Date Range Picker</h4>
    <div class="row">
      <div class="col-12 col-md-12">
        <div class="card">
          <nav class="navbar navbar-expand navbar-light bg-white topbar mb-4 static-top nav-kc">

            <div class="col-md-6">
              <div class="input-group">
                <input type="text" name="daterange" autocomplete="off" bsDaterangepicker
                  [bsConfig]="{ rangeInputFormat : 'MMMM Do YYYY', dateInputFormat: 'MMMM Do YYYY', showWeekNumbers: false }"
                  id="DateOfBirth" placeholder="Date Range" (bsValueChange)="dateRangeCreated($event)"
                  class="form-control" />
              </div>
            </div>
            <div class="col-md-3">
              <div class="input-group">
                <input type="text" name="daterange" autocomplete="off" bsDatepicker
                  [bsConfig]="{ dateInputFormat: 'MMMM Do YYYY', showWeekNumbers: false }" id="DateOfBirth"
                  placeholder="Date" (bsValueChange)="dateCreated($event)" class="form-control" />
              </div>
            </div>
          </nav>
          <div class="card-body position-relative">
            <div class="table-responsive cnstr-record product-tbl">
              <table class="table table-bordered heading-hvr">
                <thead>
                  <tr>
                    <th>ArtNo.</th>
                    <th>Brand</th>
                    <th>
                      Price/Unit</th>
                    <th>Provider</th>
                    <th>P. Art. N</th>
                    <th>S. A/C</th>
                    <th>Buy A/C</th>
                    <th>Created Date</th>
                  </tr>
                </thead>

                <tbody *ngFor="let product of products; let i = index">

                  <tr>
                    <td align="center">{{product.ArtNo}}</td>
                    <td>{{product.Brand}}</td>
                    <td>{{product.Price }}</td>
                    <td>{{product.Provider}}</td>
                    <td>{{product.ProviderArtNo}}</td>
                    <td>{{product.SalesAccount}}</td>
                    <td>{{product.BuyAccount}}</td>
                    <td>{{product.CreatedDate}}</td>
                  </tr>
                </tbody>
              </table>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

In bsConfig method we can format the date and time. showWeekNumbers is a boolean value which is true by default and displays the number of the week .

 

Also we can select the min date. max date, etc. 

<input type="text" name="daterange" autocomplete="off" bsDatepicker
                  [bsConfig]="{ dateInputFormat: 'MMMM Do YYYY', showWeekNumbers: false }" id="DateOfBirth"
                  placeholder="Date" (bsValueChange)="dateCreated($event)" class="form-control" />

Step 6

 

Now, open the ngx-bootstrap-datepicker.component.ts file and add the following code in this file.

import { Component, OnInit } from '@angular/core';
import { DatePickerService } from '../datepicker.service';

@Component({
  selector: 'app-ngx-bootstrap-datepicker',
  templateUrl: './ngx-bootstrap-datepicker.component.html',
  styleUrls: ['./ngx-bootstrap-datepicker.component.css']
})
export class NgxBootstrapDatepickerComponent implements OnInit {
  products = [];
  tempproducts=[];
  constructor(private datepickerService: DatePickerService) { }

  ngOnInit() {
    this.getProducts();
  }
  getProducts() {
    this.products = this.datepickerService.getAllProducts();
    this.tempproducts = this.datepickerService.getAllProducts();

  }
  dateCreated($event){
    this.products = this.tempproducts;
    this.products = this.products.filter(x => x.CreatedDate == $event.toJSON().split('T')[0]);
  }
  dateRangeCreated($event) {
    this.products = this.tempproducts;
    let startDate = $event[0].toJSON().split('T')[0];
    let endDate = $event[1].toJSON().split('T')[0];
    this.products = this.products.filter(
      m => new Date(m.CreatedDate) >= new Date(startDate) && new Date(m.CreatedDate) <= new Date(endDate)
    );

  }
}

Step 7

 

Create a service dataservice using the following NPM command

ng g service data

Now, open the data.service.ts file and add the following code,

import { Injectable } from '@angular/core';

@Injectable()

export class DataService {
  employees: any[];

  getAllProducts() {
    return this.employees = [
      {
        ProductId: 1,
        ArtNo: "100",
        Provider: "OppoProvider",
        ProviderArtNo: "1Yu",
        Brand: "Oppo",
        Price: 7810.23,
        BuyAccount: "123",
        SalesAccount: "321",
        CreatedDate: "2020-04-17"
      },
      {
        ProductId: 1,
        ArtNo: "101",
        Provider: "OppoProvider",
        ProviderArtNo: "1Yu",
        Brand: "Oppo",
        Price: 2310.23,
        BuyAccount: "123",
        SalesAccount: "321",
        CreatedDate: "2020-04-15"
      },
      {
        ProductId: 1,
        ArtNo: "102",
        Provider: "OppoProvider",
        ProviderArtNo: "1Yu",
        Brand: "Oppo",
        Price: 7810.23,
        BuyAccount: "123",
        SalesAccount: "321",
        CreatedDate: "2020-04-11"
      },
      {
        ProductId: 1,
        ArtNo: "103",
        Provider: "OppoProvider",
        ProviderArtNo: "1Yu",
        Brand: "Oppo",
        Price: 5810.23,
        BuyAccount: "123",
        SalesAccount: "321",
        CreatedDate: "2020-03-21"
      },
      {
        ProductId: 1,
        ArtNo: "104",
        Provider: "OppoProvider",
        ProviderArtNo: "1Yu",
        Brand: "Oppo",
        Price: 4770.23,
        BuyAccount: "143",
        SalesAccount: "211",
        CreatedDate: "2020-03-01"
      },
    ];
  }

}

Step 8

 

Now, open the app.component.html file and add the following code in the file,

<app-ngx-bootstrap-datepicker></app-ngx-bootstrap-datepicker>

Step 9

 

Let's open app.module.ts file and add the following code in the file,

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule} from '@angular/forms';
import { AppComponent } from './app.component';
import { BsDatepickerModule } from 'ngx-bootstrap/datepicker';
import { NgxBootstrapDatepickerComponent } from './ngx-bootstrap-datepicker/ngx-bootstrap-datepicker.component';

@NgModule({
   declarations: [
   AppComponent,
   NgxBootstrapDatepickerComponent
],
imports: [
   BrowserModule,
   FormsModule,
   BsDatepickerModule.forRoot()
   ],
   bootstrap: [AppComponent]
})
export class AppModule { }

Now it's time for the output,

 

 

 

Date range picker is where we can select a range of datess. After selecting date one event will fire which is an array,

 

 

 

The below image shows that it will fetch only those data which comes in the range from April 1 to April 14.

 

 

 

The below image shows the normal ngx-bootstrap datepicker.
