Vite Releases Technical Preview of Rolldown-Vite, a Rust-Based Bundler
Vite releases Rolldown-Vite, a Rust-based bundler preview offering faster builds and lower memory usage as a drop-in replacement for Vite.
WebsocketParser is a RFC6455 compliant parser for websocket messages written in Ruby. It is intended to write websockets servers in Ruby, but it only handles the parsing of the WebSocket protocol, leaving I/O to the server.
Add this line to your application's Gemfile:
gem 'websocket_parser'
And then execute:
$ bundle
Or install it yourself as:
$ gem install websocket_parser
The simplest way to use the websocket parser is to create a new one, fetch it with data and query it for new messages.
require 'websocket_parser'
parser = WebSocket::Parser.new
parser.append data
parser.next_message # return next message or nil
parser.next_messages # return an array with all parsed messages
# To send a message:
socket << WebSocket::Message.new('Hi there!').to_data
Only text or binary messages are returned on the parse methods. To intercept control frames use the parser's callbacks.
In addition to return values, you can register callbacks to get notified when a certain event happens.
require 'websocket_parser'
socket = # Handle I/O with your server/event loop.
parser = WebSocket::Parser.new
parser.on_message do |m|
puts "Received message #{m}"
end
parser.on_error do |m|
puts "Received error #{m}"
socket.close!
end
parser.on_close do |status, message|
# According to the spec the server must respond with another
# close message before closing the connection
socket << WebSocket::Message.close.to_data
socket.close!
puts "Client closed connection. Status: #{status}. Reason: #{message}"
end
parser.on_ping do |payload|
socket << WebSocket::Message.pong(payload).to_data
end
parser << socket.read(4096)
