A parser for RESP (REdis Serialization Protocol).

npm install resper

'use strict'
const Resper = require('resper')

let resper = new Resper()

resper
  .on('error', console.error)
  .on('data', console.log)
  .on('drain', () => {
    // ...
    console.log('drain')
  })

resper.write(Resper.encodeInt(998))
resper.end(Resper.encodeArray([
  Resper.encodeInt(1),
  Resper.encodeString('str'),
  [
    Resper.encodeNullArray(),
    Resper.encodeError(new Error('heheda'))
  ]
]))

Encode str to RESP buffer.

Encode err to RESP buffer.

Encode int to RESP buffer.

Encode bluk to RESP buffer, bluk could be a String or a Buffer.

Get the RESP Null buffer.

Get the RESP NullArray buffer.

Encode arr to RESP buffer, each element in arr should be an instance of buffer.

Encode requestArr to RESP request buffer, each element in requestArr should be a string.

resper.encodeRequestArray(['LLEN', 'mylist'])

Decode RESP buffer to real value. The return value is array which first element is the decode result, and the second value is the index after first CRLF.

Resper.decode(Resper.encodeInt(998))[0] // 998

Write buffer to the resper, resper will emit data event when after it parsed the buffer.

When no more data will be writen, you can call this method, and the instance of Resper will emit finish event.

function (parsedData) { }

Emitted when the instance of Resper parsed the written RESP buffer.

function (error) { }

Emitted when an error was occurred.

function () { }

Emitted when no more data in instance's inner buffer.

function () { }

Emitted when the resper.end was called.
