QRious Core is the core engine for QRious' QR code generation as well as modules to support other environments (e.g. QRious Node).

Install

Install using npm:

$ npm install --save qrious-core

You will most likely never need to depend on qrious-core directly. Instead, you will probably want to install a module that supports your desired environment. For example:

• qrious for browser
• node-qrious for Node.js

API

As this is the core of QRious, it contains all of the QR code generation logic and, since it's designed to use HTML5 canvas to render the QR code, all that consumers need to do is define and register an implementation of ElementService.

Most modules that use QRious Core will look something like the following:

var ElementService = require('qrious-core/src/service/element/ElementService');
var QRious = require('qrious-core');
 
var ExampleElementService = ElementService.extend({
  createCanvas: function() { /* ... */ },
  createImage: function() { /* ... */ },
  isCanvas: function(element) { /* ... */ },
  isImage: function(element) { /* ... */ }
});
 
QRious.use(new ExampleElementService());
 
module.exports = QRious;

This allows the core to control the primary API and keep it consistent across all environments. With the above in place, you are free to import QRious and use it as you would anywhere else.

You will find the primary API documentation on QRious. All direct consumers of core should also reference this to help developers find the information easily. However, they are encouraged to provide environment-specific examples.
