Package Exports

qr-pure-image
qr-pure-image/lib/qr.js

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 (qr-pure-image) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

qr-pure-image

Pure javascript QR code image generation.

This package is a copy off the qr-image package. The qr-image package contains some features that requires some NodeJS. In this version all of these features have been removed or updated. So this package does not have ANY external dependencies.

The api itself has also been changed to be a bit more clear.

The TypeScript declarations have also been added to the package itself instead of the @types organization.

const qr = require('qr-pure-image');
 
const qr_svg = qr.svg('I love QR!');
