Setup Angular environment

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

Copied to clipboard
npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

Copied to clipboard
ng new my-app
cd my-app

Installing Syncfusion Signature package

To install Signature package, use the following command.

Copied to clipboard
npm install @syncfusion/ej2-angular-inputs --save

The above package installs Signature dependencies which are required to render the component in the Angular environment.

Adding Signature module

Import Signature module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-inputs.

Copied to clipboard
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// Imported Syncfusion Signature module from inputs package.
import { SignatureModule } from '@syncfusion/ej2-angular-inputs';
import { AppComponent } from './app.component';
@NgModule({
    imports: [BrowserModule, SignatureModule], // Registering EJ2 Signature Module.
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

Adding Syncfusion Signature component

Modify the template in app.component.ts file with ejs-signature to render the Signature component.

Copied to clipboard
import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<!-- To Render Signature. -->
             <canvas ejs-signature #signature id="signature" ></canvas>`
})
export class AppComponent {}

Adding CSS reference

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

Copied to clipboard
@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:

Copied to clipboard
ng serve

The following example shows a basic Signature component.

@Component({
    selector: 'app-root',
    template: `<h4>Sign here</h4>
            <!-- To Render Signature. -->
            <canvas ejs-signature #signature id="signature" />`
})
export class AppComponent {}

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

enableRipple(true);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,FormsModule
    ],
    declarations: [AppComponent, SignatureComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }
Copied to clipboard
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
