PromptParse 

"All-in-one JS library for PromptPay & EMVCo QR Codes"

No dependency & Cross-platform. You can use it anywhere (Node.js, Deno, Bun), even in the browser!

Features

- Parse — PromptPay & EMVCo QR Code data strings into object
- Generate — QR Code data from pre-made templates (for example: PromptPay AnyID, PromptPay Bill Payment, TrueMoney, etc.)
- Manipulate — any values from parsed QR Code data (for example: transfer amount, account number) and encodes back into QR Code data
- Validate — checksum and data structure for known QR Code formats (for example: Slip Verify API Mini QR)

Usage

`

`ts
import { encode, tag, withCrcTag } from 'promptparse'

// Example data
const data = [
tag('00', '01'),
