Welcome to Chat Rooms Rails 6 by TANHONGIT

Complete the chat room application implementation using Ruby on Rails 6 and WebSockets.

What are WebSockets

WebSocket is actually a protocol that enables bidirectional communication between the client and the server of a web application over a single long living TCP connection.

Building the application

We are going to build the web application using:

• Ruby: version ruby 2.7.1
• Rails: version 6.0.3.2

DEMO Chat Room Application

Runing

1. Clone Repo

$ git clone https://github.com/TanHongIT/chat_room_rails_6
$ cd chat_room_rails_6

2. Bundle Install

$ bundle install

3. Yarn Install

$ yarn install

4. Create database with Postgresql

You must change the appropriate database configuration

Change configuration at "config/database.yml" with Postgresql.

default: &default
  adapter: postgresql
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000
  username: chat_room_rails_6
  password: 1234
  host: localhost

# tutorial for ubuntu linux:
# sudo -u postgres psql
# create user "chat_room_rails_6" with password '1234';  
# create database "chat_room_rails_6" owner "chat_room_rails_6"; 

development:
  <<: *default
  database: chat_room_rails_6

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: chat_room_rails_6_test

production:
  <<: *default
  database: chat_room_rails_6_production

You must change the username, password and database name accordingly!

5. run rails db:migrate

$ rails db:migrate

6. Install redis

We are going to use the redis adapter which is a safe option for production environments unlike the async one.

You first must install redis on your system.

To install it on Ubuntu you just have to execute the following commands in your terminal:

$ sudo apt update
$ sudo apt install redis-server

---

• Install redis for Windows 8.1 and previous versions. Go to https://redislabs.com/blog/redis-on-windows-8-1-and-previous-versions/

• Install redis for Windows 10: https://redislabs.com/blog/redis-on-windows-10/

---

Now open terminal and run:

redis-server

To check that installation is successful, in your terminal make sure you get a PONG:

$ redis-cli
127.0.0.1:6379> ping
PONG

7. run server

$ rails s

And now go to http://localhost:3000/
