angular2-qrcode

angular2-qrcode is a component that you can easily integrate into your project. It relies on qrious to generate QR Codes.

Breaking Changes for 2.0.0

data has been replaced with value. For those that don't need the new features of 2.0.0, just keep using 1.0.5. No change will be needed unless you upgrade.

The type field has also been removed.

Install

npm install angular2-qrcode

Woah! What's this NPM ERROR?

You will most likely get an npm error during the install process. QRious has an optional dependency for node-canvas, which requires cairo to build. We don't need this dependency, but there is no way to declare that in package.json right now. Feel free to ignore it.

Import into your NgModule

import { NgModule } from '@angular/core';
import { QRCodeModule } from 'angular2-qrcode';

    imports: [
        QRCodeModule,
        ...
    ]
})

In component template:

<div>
    <qr-code [value]="'All QR Code data goes here!'" [size]="150"></qr-code>
</div>
