React with socket.io counter example

Install

  yarn install

Run server and client

  yarn dev

Or run them as separate processes

  yarn server
  yarn client

Ideas for future iterations

• Server side validation
• Immutable server states
  • Instead persist data from some db
• Contract between server and client
  • Shared message and event types
• Client error handling
  • Network 4xx and 5xx
  • Offline / no connection / bad connection
• Server error handling
  • Handle invalid incoming emit values
