Demo

Requirements

  • AngularJS v 1.0+
  • qrcode.js (bower install qrcode is installed with angular-qr as dependecy)

Usage

We use bower for dependency management. Add

dependencies: {
    "angular-qr": "latest"
}

To your bower.json file. Then run

bower install

This will copy the angular-qr files into your bower_components folder, along with its dependencies. Load the script files in your application:

<script type="text/javascript" src="bower_components/angular/angular.js"></script>
<script type="text/javascript" src="bower_components/qrcode/lib/qrcode.min.js"></script>
<script type="text/javascript" src="bower_components/angular-qr/angular-qr.min.js"></script>

Add the ja.qr module as a dependency to your application module:

var myAppModule = angular.module('MyApp', ['ja.qr']);

Directive

$scope.string = 'YOUR TEXT TO ENCODE';
<qr text="string"></qr>
<qr type-number="8" correction-level="'M'" size="200" input-mode="'ALPHA_NUM'" text="string" image="true"></qr>

Contributing

Contributions are welcome. Please make a pull request against canary branch, use Git Commit Message Conventions and do not bump versions. Also include tests.

Testing

We use karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use gulp:

npm install -g gulp
npm install
bower install
gulp

The karma task will try to open Chrome as a browser in which to run the tests. Make sure this is available or change the configuration in karma.conf.js
