WebSocket JSON Console

A client-side web application that connects to WebSocket servers and displays streaming JSON messages in a console-like interface.

Features

  • Real-time WebSocket Connection: Connect to any WebSocket server (defaults to ws://127.0.0.1:8080)
  • JSON Message Display: Automatically formats and displays incoming JSON messages
  • Console Interface: Terminal-style dark theme with timestamped, color-coded messages
  • Connection Management: Connect/disconnect controls with real-time status indicators
  • Message Tracking: Counts and displays the number of received messages
  • Clear Console: Reset the message display at any time

Usage

  1. Open the web application
  2. Enter your WebSocket server URL (default: ws://127.0.0.1:8080)
  3. Click "Connect" to establish the connection
  4. JSON messages will stream in real-time and be displayed in the console
  5. Use "Clear" to reset the console or "Disconnect" to close the connection
