π QR Code
Generate QR codes in Deno, as base64-encoded images, completely dependency-free and requires no binary.
This is a port of zenozeng/node-yaqrcode, which itself is a port of the QR code generator in the d-project.
import { qrcode } from "https://raw.githubusercontent.com/denorg/qrcode/master/mod.ts";
const base64Image = qrcode("bitcoin:ADDRESS?amount=0.5&label=ORDER"); // data:image/gif;base64,...
You can also add a custom size by specifying size
in the second parameter:
const fixedSizeImage = qrcode("bitcoin:ADDRESS?amount=0.5&label=ORDER", { size: 500 });
Alternatively, you can use it directly from the CLI:
deno run https://raw.githubusercontent.com/denorg/qrcode/master/cli.ts <text>
You can also install it globally using the following:
deno install qrcode https://raw.githubusercontent.com/denorg/qrcode/master/cli.ts
Then, the package is available to run:
qrcode <text>
