micro-rlp

micro-rlp

Node+Browser-friendly fork of rlp with following changes:

• Removes dependency on bn.js, which makes library zero-dep
• Replaces bigints from bn.js with native BigInts
• Replaces all instances of Buffer usage with Uint8Array - which is a superclass of Buffer, which makes rlp browser-friendly

Install via:

npm install micro-rlp

SYNOPSIS

or #ethereumjs on freenode

Recursive Length Prefix Encoding for node.js.

INSTALL

npm install rlp

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

USAGE

var RLP = require('rlp')
var assert = require('assert')

var nestedList = [[], [[]], [[], [[]]]]
var encoded = RLP.encode(nestedList)
var 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>
