I want, when i will access my POS website via my phone, then i can scan barcode by phone camera.
Already i try quaggajs and html5-qrcode but sometimes they are give me wrong answer and it’s very slow.
Can you give me a solution to do it?

You can use @zxing/library npm package to implement this.
See below code to implement
// use with commonJS
const { MultiFormatReader, BarcodeFormat } = require('@zxing/library');
// or with ES6 modules
import { MultiFormatReader, BarcodeFormat } from '@zxing/library';
const hints = new Map();
const formats = [BarcodeFormat.QR_CODE, BarcodeFormat.DATA_MATRIX/*, ...*/];
hints.set(DecodeHintType.POSSIBLE_FORMATS, formats);
const reader = new MultiFormatReader();
const luminanceSource = new RGBLuminanceSource(imgByteArray, imgWidth, imgHeight);
const binaryBitmap = new BinaryBitmap(new HybridBinarizer(luminanceSource));
reader.decode(binaryBitmap, hints);
