Typescript Flat Decoder

This project aims to provide a flat binary decoder. It is written in Typescript and can be used in both NodeJS and the browser.

Getting Started

npm i @cardano-foundation/cf-flat-decoder-ts

Usage

You can use the decoder in node backend but also in the browser. This example shows how to use it in a React app.

import { useState } from 'react';
import { decodeFlatUplc, Term } from '@cardano-foundation/cf-flat-decoder-ts';

function App() {
  const [deserializeContract, setDeserializeContract] = useState(
