angular date picker with code examples

Angular date picker is a popular component in the Angular framework for selecting or inputting dates with ease. It provides a simple and elegant user interface to select dates, which can be customized with various options and features.

In this article, we will discuss the angular date picker and its implementation with code examples.

Prerequisites

To work with the date picker, you should have a basic understanding of the Angular framework, HTML, and CSS.

Date Picker Component

The Angular date picker is a component that can be easily integrated into your application. It is created using the DatepickerModule that should be imported in the app.module.ts file.

Importing the DatepickerModule in the app.module.ts file:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatInputModule } from '@angular/material/input';
@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    FormsModule,
    BrowserAnimationsModule,
    MatDatepickerModule,
    MatFormFieldModule,
    MatInputModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {}

Once we have imported all the required modules, we can start using the date picker component. To use it we have to add the following code inside the HTML template of the component.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Here we have used the MatDatepickerModule, MatInputModule, and MatFormFieldModule modules.

When you run the application, you will see a input field where you can click to select the date, and a calendar picker will appear to choose the desired date.

Customization

The Angular date picker can be easily customized according to user requirements and preferences. One can customize the date range, format, and styles.

Setting the Date Range

To set the date range, we can use the min and max properties of the MatDatepicker.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date between 2nd and 30th" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker [min]="minDate" [max]="maxDate"></mat-datepicker>
</mat-form-field>
minDate = new Date(2021, 4, 2);
maxDate = new Date(2021, 4, 30);

Setting the Date Format

To set the date format, we can use the dateClass property of the MatDatepicker.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date format 'dd.MM.yyyy'" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker [dateClass]="dateClass()" [startView]="'month'"></mat-datepicker>
</mat-form-field>
dateClass() {
  return (date: Date): MatCalendarCellCssClasses => {
    const day = date.getDate();
    return day === 4 ? 'example-custom-date-class' : '';
  };
}

Here the method 'dateClass' returns a function that adds a custom class to the date '4th of every month' using the CSS class 'example-custom-date-class'.

Setting the Style

To set the styles, we can use CSS variables to change the appearance of the date picker.

::ng-deep .custom-date-picker {
  --primary: coral;
  --background: #f5f5f5;
  --foreground: #333;
}

::ng-deep .custom-date-picker-button span {
  font-size: 1.2em;
  color: var(--primary);
}

Changing the date picker styles is not recommended by Angular as it relies on stable APIs that may change in a future version.

Conclusion

In this article, we have learned how to use the Angular date picker component and how it can be easily customized according to user requirements. We have covered setting the date range, format, and styles. The Angular date picker is a simple and elegant solution for selecting or inputting dates.

The complete code sample can be found on the official Angular Material documentation [https://material.angular.io/components/datepicker/overview]

let's dive a bit deeper into the topics covered in the previous article.

Prerequisites

Before we start using the Angular date picker, it's essential to have a basic understanding of the Angular framework, HTML, and CSS. If you're new to Angular, I'd recommend checking out the official Angular documentation [https://angular.io/] before proceeding.

Date Picker Component

The DatepickerModule is a part of the Angular Material library [https://material.angular.io/] and must be imported before using the date picker component. Once we've imported the DatepickerModule, we can start using the date picker component.

In the HTML template, we create a form field with an input element that has a reference to the date picker via the 'matDatepicker' attribute. We also add a date picker toggle button via the 'mat-datepicker-toggle' attribute, and a date picker element via the 'mat-datepicker' attribute.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Here, the date picker toggle is added as a suffix to the input field, and when clicked, the date picker element appears below the input field.

Customization

The Angular date picker component offers several customization options to suit a wide range of needs. Some of the key customization options include setting the date range, format, and styles.

Setting the Date Range

By default, the Angular date picker allows any date to be selected. However, in some cases, we might want to limit the range of selectable dates. To set the date range, we can use the 'min' and 'max' properties of the date picker element.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date between 2nd and 30th" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker [min]="minDate" [max]="maxDate"></mat-datepicker>
</mat-form-field>

Here, the 'minDate' and 'maxDate' values are set to restrict the selectable dates between the 2nd and 30th of May 2021.

Setting the Date Format

By default, the Angular date picker displays dates in the format 'MM/DD/YYYY'. However, we can customize the date format by using the 'matDatepicker' attribute and 'dateClass' function.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date format 'dd.MM.yyyy'" />
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker [dateClass]="dateClass()" [startView]="'month'"></mat-datepicker>
</mat-form-field>
dateClass() {
  return (date: Date): MatCalendarCellCssClasses => {
    const day = date.getDate();
    return day === 4 ? 'example-custom-date-class' : '';
  };
}

In this example, we've customized the date format to display dates in the format 'dd.MM.yyyy'. The 'dateClass' function returns a function that adds a custom CSS class to the '4th' of every month, using the 'example-custom-date-class' class.

Setting the Style

We can also customize the styles of the date picker element using CSS variables. However, it's important to note that changing the date picker style via CSS is not advisable in Angular as it might break the component.

::ng-deep .custom-date-picker {
  --primary: coral;
  --background: #f5f5f5;
  --foreground: #333;
}

::ng-deep .custom-date-picker-button span {
  font-size: 1.2em;
  color: var(--primary);
}

In this example, we've used the CSS variables to change the primary, background, and foreground colors of the date picker. We've also changed the font size and color of the date picker toggle button using the 'custom-date-picker-button' class.

Conclusion

In this article, we've learned how to use the Angular date picker component, and how it can be easily customized using various options and features. We've covered setting the date range, format, and styles of the date picker component. By using these customization options, we can build a robust and user-friendly date picker in our Angular application.
