SYNOPSIS

Recursive Length Prefix Encoding for Node.js.

INSTALL

npm install rlp

install with -g if you want to use the cli.

USAGE

import * as assert from 'assert'
import * as rlp from 'rlp'

const nestedList = [[], [[]], [[], [[]]]]
const encoded = rlp.encode(nestedList)
const decoded = rlp.decode(encoded)
assert.deepEqual(nestedList, decoded)

API

rlp.encode(plain) - RLP encodes an Array, Buffer or String and returns a Buffer.

rlp.decode(encoded, [skipRemainderCheck=false]) - Decodes an RLP encoded Buffer, Array or String and returns a Buffer or an Array of Buffers. If skipRemainderCheck is enabled, rlp will just decode the first rlp sequence in the buffer. By default, it would throw an error if there are more bytes in Buffer than used by rlp sequence.

CLI

rlp decode <hex string>
rlp encode <json String>
