    socket-core

    Core database, replication, swarming, and chat APIs for socket.

    Usage

    npm install socket-core
    

    API

    var Socket = require('socket-node')

    var socket = Socket([storage][, uriString][, opts])

    Create a socket p2p database using storage storage, which must be either a string (filepath to directory on disk) or an instance of random-access-storage.

    uriString is a socket URI string, of the form socket://<hexkey>[?param1=value1&param2=value2. A hexidecimal key on its own will also be understood.

    If this is a new socket, key can be omitted and will be generated.

    You can pass opts.db as a levelup or leveldown instance to use persistent storage for indexing instead of using memory. For example:

    var level = require('level')
    var socket = Socket(storage, key, { db: level('/tmp/bot.db') })

    socket.getLocalKey(cb)

    Returns the local user's key (as a hex string).

    var ds = socket.replicate()

    Creates a new, live replication stream. This duplex stream can be piped into any transport expressed as a node stream (tcp, websockets, udp, utp, etc).

    socket.ready(cb)

    Call cb() when the underlying indexes are caught up.

    Channels

    socket.channels.get(function (error, channels) {})

    Retrieve a list of all channel names that exist in this socket.

    socket.channels.events.on('add', function (channel) {})

    Emitted when a new channel is added to the socket.

    Messages

    var rs = socket.messages.read(channel, opts)

    Returns a readable stream of messages (most recent first) from a channel.

    Pass opts.limit to set a maximum number of messages to read.

    socket.messages.events.on('message', fn)

    Calls fn with every new message that arrives, regardless of channel.

    socket.messages.events.on(channel, fn)

    Calls fn with every new message that arrives in channel.

    Network

    var swarm = require('socket-core/swarm')

    socket.swarm(cb)

    Joins the P2P swarm for a socket. This seeks out peers who are also part of this socket by various means (internet, local network), connects to them, and replicates socket messages between them.

    The returned object is an instance of discovery-swarm.

    socket.on('peer-added', function (key) {})

    Emitted when you connect to a peer. key is a hex string of their public key.

    socket.on('peer-dropped', function (key) {})

    Emitted when you lose a connection to a peer. key is a hex string of their public key.

    Moderation

    socket has a subjective moderation system.

    The three roles are "admin", "moderator", and "ban/key".

    Any admin/mod/ban operation can be per-channel, or socket-wide (the @ group).

    Every user sees themselves as an administrator across the entire socket. This means they can grant admin or moderator powers to anyone, and ban anyone, but only they will see its affects on their own computer.

    A socket can be instantiated with a moderation key. This is an additional key to locally consider as a socket-wide administrator (in addition to yourself).

    This means that if a group of people all specify the same moderation key, they will collectively see the same set of administrators, moderators, and banned users.

    var rs = socket.moderation.listBans(channel)

    Return a readable objectMode stream of bans for channel.

    Each ban is an object with either a key or ip property.

    To list socket-wide bans use the special channel @.

    socket.moderation.isBanned({ ip, key, channel }, cb)

    Determine whether a user identified by ip and/or key is banned on channel or socket-wide as cb(err, banned) for a boolean banned. If channel is omitted, only check socket-wide.

    Publishing

    socket.publish(message, opts, cb)

    Publish message to your feed. message must have a type field set. If not, it defaults to chat/text. In general, a message is formatted as

    {
      type: 'chat/text',
      content: {
        text: 'hello world',
        channel: 'socket-dev'
      }
    }

    A timestamp field is set automatically with the current system time.

    type is an unrestricted field: you can make up new message types and clients will happily ignore them until someone implements support for them. Well documented types include

    chat/text

    {
      type: 'chat/text',
      content: {
        text: 'whatever the user wants to say',
        channel: 'some channel name. if it didnt exist before, it does now!'
      }
    }

    mod/{add,remove}

    {
      type: '"mod/add" or "mod/remove"',
      content: {
        key: 'hex string key of the user to add/remove as mod',
        channel: 'channel name as a string or "@" for socket-wide'
        role: '"admin", "mod", or a custom role string'
      }
    }

    ban/{add,remove}

    {
      type: '"ban/add" or "ban/remove"',
      content: {
        key: 'hex string key of the user to ban/unban',
        channel: 'channel name as a string or "@" for socket-wide'
      }
    }
