Recursive Length Prefix Encoding for node.js.

npm install rlp

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

var RLP = require('rlp'); var assert = require('assert'); var nestedList = [ [], [[]], [ [], [[]] ] ]; var encoded = RLP.encode(nestedList); var decoded = RLP.decode(encoded); assert.deepEqual(nestedList, decoded); 

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.

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