Tamashii

Tamashii is a package designed for IoT. You can write the WebSocket server and client easily by using this gem.

Add the following code to your Gemfile

gem 'tamashii'

And then execute:

$ bundle install

Or install it yourself with:

$ gem install tamashii

There are two section in Tamashii, Server and Client, is responsible for the WebSocket server and client, respectively.

Server section is a server designed based on Rack, it can not only be easily compatible with the web server, such as Puma, Passenger, but also be used as a module in the Rails and other projects.

To start the server, generate config.ru and add the following code to it.

require 'tamashii/server'

run Tamashii::Server::Base.new

Then, you can start the server with:

$ rackup

If you want to start the server with other web server, such as Puma:

$ puma

You can refer to the project in tamashii-manager in the IoT server application.

In Tamashii, we only need to focus on how to connect with WebSocket users to exchange information, on the process of multi-process web server problems have been resolved in Tamashii.

We can create a Client object to handle the behavior of each user.

Tamashii::Server.config do |config|
  config.connection_class = Client
end

In Client , there are four events that need to be handled.

• on_open : when the user is connected to the server
• on_message : when the server receives the message from user
• on_error : when the server gets an error
• on_close : when the connection is shut down

In most cases, we only need to deal with parts of on_message , the other events can be handled as needed.

class Client
  def on_message(data)
    # Processing for the received Data (Binary)
  end
end

By default Tamashii will broadcast the received message to other clients automatically.

The client is in another repository: tamashii-client
