README

This README would normally document whatever steps are necessary to get the application up and running.

Things you may want to cover:

• Ruby version: 3.0.0

• System dependencies:

  • Redis: 4.2.5
  • postgreSQL

• Database creation: ( We will using simple settings for a objective getting started )

  • host: localhost
  • user: postgres
  • password: postgres

• Database initialization:

  rake db:craete
  rake db:migrate
  rails server

Building own real time

• Add redis gem in your Gemfile and run bundle install

    gem 'redis'

• Configure the development settings in cable.yml file:

development:
  adapter: redis
  url: redis://localhost:6379/1

• Generate a new channel. This will also generate a consumer (See the .js file). Define a string id that represents this channel.

rails g channel chat_room  

def subscribed
  stream_from "chat_room_channel"
end

OBS: With some consoles, you can test the connectivity just by opening the Rails console and pasting the following command

/* app/javascript/chanels/chat_room_channel */

import consumer from "./consumer"

consumer.subscriptions.create("ChatRoomChannel", {
  connected() {
    // Called when the subscription is ready for use on the server
    console.log('Channel Connected!!!');
  },

  disconnected() {
    // Called when the subscription has been terminated by the server
    console.log('Channel Disconnected!!!');
  },

  received(data) {
    // Called when there's incoming data on the websocket for this channel
    console.log('Message: ', data);
  }
});

Bash: rails console

ActionCable.server.broadcast("channel_name", { message: 'Hello world', type: 'text' })
