SLP Parser

slp-parser is a JavaScript Library for parsing Simple Ledger Protocol (SLP) metadata. TokenType1 and NFT1 tokens are supported. This repo is designed to be easy to port to other languages.

Installation

For node.js

npm install slp-parser

For browser

<script src='https://unpkg.com/slp-parser'></script>

Examples

This library does not perform any validation of the inputs, dealing solely with parsing the OP_RETURN messages SLP uses to function. If this is not clear, please read the slp-specifications.

NOTES:

• The BigNumber.js library is used to avoid precision issues with numbers having more than 15 significant digits. This can be accessed with slpParser.BN.

How to parse

This library has a single method called parseSLP which takes either a Buffer or a hex-string and returns an object such as described with the type definitions inside ./lib/index.ts.

There are additional examples in examples folder.

Node.js

const slpParser = require('slp-parser');
const obj = slpParser.parseSLP(Buffer.from('6a04534c500001010747454e455349534c004c004c004c0001004c00080000000000000064', 'hex'));
console.log(obj);
