Package Exports

bwip-angular2

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bwip-angular2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

metafloor/bwip-js library modification for Angular2+.

Installation

npm install bwip-angular2

After the installation of the library you must copy the folder "fonts" from 'node_modules/bwip-js/' to the '/src/assets' and rename it (the folder "fonts") to "bwipjs-fonts"

Usage

import { Component } from '@angular/core';
import bwipjs from 'bwip-angular2';

@Component({
  selector: 'barcode',
  template: `<button (click)="renderBarcode()">Click to render</button>
  <canvas id="barcodeCanvas"></canvas>
  <div id="err"></div>`,
  styleUrls: ['./barcode-component.sass']
})

export class BarcodeComponent  {

  public renderBarcode(): void {
    bwipjs('barcodeCanvas', {
      bcid: 'code128',        // Barcode type
      text: '987654321',   	  // Text to encode
      scale: 3,               // 3x scaling factor
      height: 10,             // Bar height, in millimeters
      width: 10,
      includetext: true,      // Show human-readable text
      textxalign: 'center',   // Always good to set this
    }, (err, cvs) => {
      if (err) {
        document.getElementById('err').innerText = 'Error occured. See browser log for more information';
        console.log(err);
      } else {
      }
    });
  }
}
