## INSTALL

`npm install rlp`

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

## USAGE

```javascript
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>`

## TESTS

Test uses mocha. To run tests and linting: `npm test`. To auto fix linting problems use: `npm run test:fix`.
