Live chat is the primary feature of Strife and utilizes ActionCable - Integrated WebSockets for Rails Action Cable.

Ruby
ChannelChannel
def subscribed
    @channel = Channel.find_by(id: params[:id])
    stream_for @channel
  end

Javascript
this.CableApp.messages = this.CableApp.cable.subscriptions.create(
      {
        channel: "ChannelChannel",
        id: this.props.channel.id,
      },
      {
        received: (message) => {
          this.getResponseMessage(message);
        },
      }
    );
  }

Action Cable creates a subscription which listens for new messages associated with the appopriate channel.

Ruby
def create
    @message = Message.new(message_params)
    @channel = Channel.find(message_params['channel_id'])
    if @message.save
      ChannelChannel.broadcast_to(
        @channel,
        { json: @message.to_json(include: :author) },
      )
      render json: @message.to_json(include: :author)
    else
      render json: @message.errors.full_messages, status: 422
    end
  end

When a new message is created it broadcasts the message to the appopriate channel and for users who are subscribed to the channel they will receive the message in real time.

Users can create, edit and add members to servers and channels.
