Getting started with Angular Barcode component

21 Sep 20237 minutes to read

This section explains you the steps required to create a simple barcode and demonstrate the basic usage of the barcode control.

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 Barcode Generator 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,

1. Ivy library distribution package format
2. 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-barcode-generator package to the application.

npm install @syncfusion/ej2-angular-barcode-generator --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-barcode-generator@ngcc package to the application.

npm install @syncfusion/ej2-angular-barcode-generator@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-barcode-generator:"20.2.38-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 Barcode Generator package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install Barcode Generator component, use the following command.

npm install @syncfusion/ej2-angular-barcode-generator --save

The –save will instruct NPM to include the barcode generator package inside of the dependencies section of the package.json.

Registering Barcode Generator Module

Import Barcode Generator module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-barcode-generator [src/app/app.module.ts].

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BarcodeGeneratorAllModule,QRCodeGeneratorAllModule,DataMatrixGeneratorAllModule } from '@syncfusion/ej2-angular-barcode-generator';
import { AppComponent }  from './app.component';

@NgModule({
  //declaration of ej2-angular-Barcode Generator module into NgModule
  imports:      [ BrowserModule, BarcodeGeneratorAllModule, QRCodeGeneratorAllModule ,DataMatrixGeneratorAllModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding Barcode Generator control

You can start adding Essential JS 2 barcode-generator component to the application. To get started, add the Angular Barcode component in app.ts and index.html files using the following code.

app.component.ts

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

@Component({
  selector: "app-container",
  // specifies the template string for the barcode generator component
  template: `<ejs-barcodegenerator style="display: block;"  #barcode id="barcode" width="200px" height="150px" mode="SVG" type="Codabar" value="123456789">`
})
export class AppComponent {}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { BarcodeGeneratorAllModule,QRCodeGeneratorAllModule,DataMatrixGeneratorAllModule } from '@syncfusion/ej2-angular-barcode-generator';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,  BarcodeGeneratorAllModule, QRCodeGeneratorAllModule ,DataMatrixGeneratorAllModule 
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Adding QR Generator control

You can add the QR code in our Angular Barcode Generator component.

app.component.ts

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

@Component({
  selector: "app-container",
  // specifies the template string for the barcode generator component
  template: `<ejs-qrcodegenerator style="display: block;"  #barcode id="barcode" width="200px" height="150px" mode="SVG"value="Syncfusion"></ejs-qrcodegenerator>`
})
export class AppComponent {}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { BarcodeGeneratorAllModule,QRCodeGeneratorAllModule,DataMatrixGeneratorAllModule } from '@syncfusion/ej2-angular-barcode-generator';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,  BarcodeGeneratorAllModule, QRCodeGeneratorAllModule ,DataMatrixGeneratorAllModule 
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Adding Datamatrix Generator control

You can add the datamatrix code in our Angular Barcode Generator component.

app.component.ts

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

@Component({
  selector: "app-container",
  // specifies the template string for the barcode generator component
  template: `<ejs-datamatrixgenerator style="display: block;"  #barcode id="barcode" width="200px" height="200px" mode="SVG"
                        type="DataMatrix" value="Syncfusion">
                    </ejs-datamatrixgenerator>`
})
export class AppComponent {}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { BarcodeGeneratorAllModule,QRCodeGeneratorAllModule,DataMatrixGeneratorAllModule } from '@syncfusion/ej2-angular-barcode-generator';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,  BarcodeGeneratorAllModule, QRCodeGeneratorAllModule ,DataMatrixGeneratorAllModule 
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
