Seamlessly Integrate DateTime Picker Component in Angular Applications

DateTime Picker Component: A Comprehensive Guide on Implementation

As more and more web applications lean towards rich user interfaces that offer a smooth, seamless experience, the need to integrate UI components that enhance the user experience arises. One such component that developers find highly useful is a date-time picker component.

A date-time picker component, as the name suggests, is a UI widget that eases the process of selecting date and time on a form. In this article, we will provide a comprehensive guide on the implementation of the date-time picker component using Angular Material Dependency and ng-bootstrap library.

Part 1: Implementation of DateTime Picker Component with Angular Material Dependency

The DateTime Picker Component is an essential aspect of personal information forms that require the selection of date of birth, job start and end date, and other time-related fields that are required in forms. The following steps are involved in implementing the DateTime Picker Component using Angular Material Dependency:

Step 1: Creating the basic structure and behavior of the component

The creation of the Date Picker Component involves setting up the basic structure and behavior of the component.

This structure defines the layout and behavior of the component from which the user can select a date. The structure can be achieved using Angular Material UI.

Step 2: Importing dependencies from Angular Material into app.module.ts

Once the structure and behavior are defined, the next step is to import the required dependencies from Angular Material into the app.module.ts file. This action makes the DatePickerComponent available throughout the application.

Part 2: Implementation of DateTime Picker Component with ng-bootstrap Library

Another library used in implementing the DateTime Picker Component is the ng-bootstrap library, which provides a rich set of widgets for Angular applications. The following steps are required to implement the DateTime Picker Component using ng-bootstrap:

Step 1: Installing ng-bootstrap

Before using the ng-bootstrap DateTime Picker Component, we must first install ng-bootstrap by running the command “npm install –save @ng-bootstrap/ng-bootstrap” in the terminal.

Step 2: Creating the structure and behavior of the component in app.component.html

Next, we create the structure and behavior of the DateTime Picker Component in the app.component.html file. This structure defines how the component will look and behave when a date is selected.

Step 3: Defining functionality of the component in app.component.ts

After creating the structure, the next step is to define the functionality of the component in the app.component.ts file. This file defines what happens when a user selects a date from the DateTime Picker.

Step 4: Managing dependencies in app.module.ts

Finally, we must manage the dependencies required by ng-bootstrap in the app.module.ts file. This ensures that the DateTime Picker Component is available throughout the application.

Conclusion

In conclusion, the DateTime Picker Component is a vital component in any form that requires the selection of a date or time. By following the outlined steps in this article, a developer can seamlessly integrate a DateTime Picker Component into an Angular application using either Angular Material Dependency or the ng-bootstrap library.

Part 3: Implementation of DateTime Picker Component with ng2 NPM

Angular developers can also use the ng2 NPM package to implement the DateTime Picker Component. This package offers a wide range of useful functionalities such as a date picker component, a time picker component, and a range picker component.

In this section, we will provide a detailed guide on how to implement the DateTime Picker Component using ng2 NPM in an Angular application. Step 1: Installing ng2 library

To get started, we need to install the ng2 NPM package by running the command “npm install ng2-datepicker –save” in the terminal.

This command installs the ng2-datepicker library, which provides a set of useful Date Picker Component functionalities. Step 2: Creating the structure and behavior of the component in app.component.html

After installing the ng2-datepicker library, the next step is to create the structure and behavior of the DateTime Picker Component in the app.component.html file.

Here, we define the layout and behavior of the component, such as the options available for selecting a date and the format in which the date is displayed. To create the DateTime Picker component in app.component.html, declare it using a ‘dp-date-picker’ tag and specify the properties of the date-picker like minDate, maxDate, and dateFormat.

An example is shown below:

“`

“`

The above example provides an overview of how to set up the DateTime Picker Component in app.component.html using ng2 NPM. Step 3: Defining functionality of the component in app.component.ts

Once the structure and behavior of the DateTime Picker Component are defined in app.component.html, we then define the logic of the component in app.component.ts file.

Here, we use ng2 modules to update the format of the date picker component and display the selected date. To achieve this, we import the “DatePickerOptions” module from ng2-datepicker and create an instance of this module with a default date format.

We then define a function called “updateFormat()” that updates the “dateFormat” property of the DatePickerOptions module to display the selected date in a new format. “`

import { Component } from ‘@angular/core’;

import { DatePickerOptions, DateModel } from ‘ng2-datepicker’;

@Component({

selector: ‘app-root’,

templateUrl: ‘./app.component.html’,

styleUrls: [‘./app.component.css’]

})

export class AppComponent {

public selectedDate: DateModel;

public options: DatePickerOptions;

constructor() {

this.options = new DatePickerOptions();

this.options.dateFormat = ‘DD/MM/YYYY HH:mm’;

}

updateFormat() {

this.options.dateFormat = ‘YYYY-MM-DD HH:mm’;

}

}

“`

In the above example, we declare a property called “options” of the DatePickerOptions type.

We provide a default value to the “dateFormat” property of this instance to customize how the date is displayed in the DateTime Picker Component. We then define a function called “updateFormat()” that updates the “dateFormat” property to a new format.

Step 4: Managing dependencies in app.module.ts

After defining the logic of the DateTime Picker Component in app.component.ts, the final step is to manage the dependencies in app.module.ts. This ensures that the DateTime Picker Component works seamlessly throughout the application.

To manage dependencies, we need to update the “tsconfig.json” file to enable Angular to use the ng2-datepicker library. We can do this by adding “node_modules/ng2-datepicker/dist” to the “include” list under the “compilerOptions” object in the “tsconfig.json” file.

“`

{

“compileOnSave”: false,

“compilerOptions”: {

“baseUrl”: “./src”,

“outDir”: “./dist/out-tsc”,

“sourceMap”: true,

“declaration”: false,

“moduleResolution”: “node”,

“emitDecoratorMetadata”: true,

“experimentalDecorators”: true,

“target”: “es5”,

“typeRoots”: [

“node_modules/@types”

],

“lib”: [

“es2017”,

“dom”

],

“include”: [

“src/**/*.ts”,

“node_modules/ng2-datepicker/dist”

]

}

}

“`

In the above example, we added “node_modules/ng2-datepicker/dist” to the “include” list.

Conclusion

In conclusion, by following the steps outlined in this article, Angular developers can easily implement the DateTime Picker Component using various libraries such as Angular Material Dependency and ng-bootstrap and the ng2-datepicker NPM package. These date picker components provide an enhanced user experience and make interacting with forms a lot easier for users.

In conclusion, the implementation of the DateTime Picker Component is crucial in the development of rich user interfaces for web applications. This article has provided a comprehensive guide on how to implement the DateTime Picker Component using Angular Material Dependency, ng-bootstrap, and the ng2-datepicker NPM package.

Each library provides a set of useful functionalities, including creating the structure and behavior of the component in the app.component.html file, defining the logic of the component in the app.component.ts file, and managing dependencies in the app.module.ts file.
