Spocket

Socket with easy message encoding and decoding.

Spocket, a drop-in replacement for net's Socket class, provides a simplistic and modular way to encode and decode messages through plain JavaScript functions (or npm-hosted algorithms).

const example = new Spocket({ ...opts });

// ...

example.on('message', function(data) {
  console.log(data.foo.bar);
});

example.send({
  foo: 123,
  bar: {
    baz: 'Qux!'
  }
});

You can also create a Spocket from a Socket:

var example = Spocket.from(socket, { ...opts });

Installation

$ npm install --save spocket

Usage

import Spocket from 'spocket';

Spocket([opts]) (extends net.Socket)

The Spocket class is drop-in compatible with net.Socket, because it actually is a net.Socket class with a few additions. Events, methods, and properties from net.Socket all work.

• opts (Object) Any of net.Socket's options or Spocket's extras.
• opts.encode (Function) A function used to encode messages.
• opts.decode (Function) A function used to decode messages.
• opts.algo (Object) An alternative algorithm object for encoding and decoding.

Example:

new Spocket({
  // An option passed to net.Socket
  writable: false,

  // Encoding and decoding
  encode: function(object) { ... },
  decode: function(buffer) { ... },

  // Algorithm object, alternative to the above.
  algo: websocket,
});

Event: 'message'

This event is emitted after 'data' with the decoded message.

• data (Anything) Decoded message.

Example:

foo.on('message', function(data) {
  console.log(data.foo.bar);
});

Spocket#send(message, [encoding, callback])

The same as net.Socket#write except that message gets encoded.

Example:

foo.send({
  foo: 123,
  bar: {
    baz: 'Qux!',
  },
})
