zebra-striped v0.2.2

Generate barcodes natively in React Native with the ZXing library underhood!

The story behind

When I was working on generating QR codes in one of the apps for a client, I realized that JS-based libraries like BWIP JS are not very performant in React Native apps, where performance is especially important for keeping users happy.

I decided to experiment a little and learn about Expo Native Modules, Swift, and Kotlin. This led to the creation of zebra-striped - a performant, native-based library for generating various types of barcodes for React Native.

Feedback is highly appreciated!

Usage

Here's a basic usage of ZebraCode component:

<ZebraCode
  value={"I'm very striped!"}
  format="qr"
  size={{ width: 300, height: 300 }}
/>

Want a custom colors? 🎨 I've got you covered:

<ZebraCode
  value={"I'm very striped!"}
  format="qr"
  size={{ width: 300, height: 300 }}
  onColor="#141414"
  offColor="#ffffff"
/>

(Colors are accepted only in HEX)

Or maybe you just want to have a data returned in Base64 format? Here's how you can do it:

const base64Image = getBase64Code("I'm base64'ed!", "qr", {
  width: 300,
  height: 300,
});

const base64Image = getBase64Code("I'm custom-colored!", "qr", {
    width: 300,
    height: 300
}, "#141414", #ffffff);
