This section explains how to create a default OTP Input and demonstrate the basic usage of the OTP Input component.

Dependencies

The list of dependencies required to use the OTP Input component in your application is given below:

|-- @syncfusion/ej2-angular-inputs
    |-- @syncfusion/ej2-angular-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-inputs

Setup Angular environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion OTP Input package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

Ivy library distribution package format
Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-inputs package to the application.

npm install @syncfusion/ej2-angular-inputs --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-inputs@ngcc package to the application.

npm install @syncfusion/ej2-angular-inputs@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-inputs:"20.4.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding Syncfusion OTP Input component

Modify the template in app.component.ts file to render the OTP Input component.

import { OtpInputModule } from '@syncfusion/ej2-angular-inputs'
import { Component } from '@angular/core';

@Component({
imports: [
        OtpInputModule
    ],
    standalone: true,
    selector: 'app-root',
    template: `<!-- To Render OTP Input component. -->
      <div class="wrap">
          <div id='otp-container' style="width: 350px;">
              <div ejs-otpinput id="otpinput"></div>
          </div>
      </div>`
})

export class AppComponent { }

Adding CSS reference

Add OTP Input component’s styles as given below in style.css.

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a default OTP Input component.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { OtpInputModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, OtpInputModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render OTP Input component. -->
    <div class="wrap">
        <div id='otp-container' style="width: 350px;">
            <div ejs-otpinput id="otpinput"></div>
        </div>
    </div>`
})

export class AppComponent { }
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
