Encode QR Code by using N-API. The QR code generating library is QR Code generator library
You need to set up the Rust development environment: rustup
You can use the encodeString function to encode a string or use the encodeBuffer function to encode a buffer into QR Code data which is an array of buffers (Buffer[]).
import { encodeString } from "magic-qr-code";
const result = encodeString("https://magiclen.org".toUpperCase());

*/Encoding QR code, you can also set the error correction level by passing a ErrorCorrection number to the second argument.
import { encodeString, ErrorCorrection } from "magic-qr-code";
const result = encodeString("https://magiclen.org".toUpperCase(), ErrorCorrection.High);
