SYNOPSIS

LEB128 encoding and decoding for signed and unsinged intergers. Supports arbitary length intergers larger then Number.MAX_SAFE_INTEGER

INSTALL

npm install leb128

USAGE

const leb = require('leb128')
let encoded = leb.unsigned.encode('9019283812387')
console.log(encoded)
// <Buffer a3 e0 d4 b9 bf 86 02>

let decoded = leb.unsigned.decode(encoded)
console.log(decoded)
// 9019283812387

encoded = leb.signed.encode('-9019283812387')
console.log(encoded)
// <Buffer dd 9f ab c6 c0 f9 7d>

decoded = leb.signed.decode(encoded)
console.log(decoded)
// '-9019283812387'
