What is the use of Bootstrap Datepicker in Angular?

In this article, we will see the use of Bootstrap Datepicker in Angular. The Datepicker is used to make a component that will be shown by using a calendar and we can select the date from it. Adding Bootstrap to the Angular Project can make the better UI design, along with providing some in-built classes for Date that help us to implement it directly.

Bootstrap Datepicker in Angular can be used in the following ways:

• Adding Bootstrap through Angular CLI & NPM, & then creating & using the Datepicker Component
• By installing the Angular ngx Bootstrap & then using the Datepicker Component (Angular ng Bootstrap Datepicker Component)

Steps for Installing & Configuring the Angular Application

Step 1: Create an Angular application using the following command.

ng new appname

Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

Step 3: Install dependency

ng add @ng-bootstrap/ng-bootstrap
npm install --save angular-bootstrap-datetimepicker bootstrap moment open-iconic

Step 4: Add CSS to ./src/styles.css

@import '~bootstrap/dist/css/bootstrap.min.css';
@import '~open-iconic/font/css/open-iconic-bootstrap.css';

Project Structure

It will look like the following:

Example 1: In this example, we will create a simple Bootstrap Datepicker in Angular. We will be adding Bootstrap through Angular CLI & NPM, & then creating & using the Datepicker Component.
