SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enables real-time, bi-directional communication between clients and servers, overcoming the limitations of traditional request-response models by allowing servers to push data proactively.

Core Features & Use Cases

  • Full-Duplex Communication: Establishes a persistent, full-duplex channel over a single TCP connection.
  • WebSocket Handshake: Implements the HTTP-based handshake for upgrading connections.
  • Client-Side Implementation: Provides JavaScript examples for creating, sending, receiving, and closing WebSocket connections.
  • Server-Side Implementation: Details how to create WebSocket servers using %CSP.WebSocket in InterSystems IRIS, including synchronous and asynchronous operation modes.
  • Use Case: Building a live chat application, real-time stock tickers, or collaborative editing tools where immediate data updates are crucial.

Quick Start

Implement a WebSocket server by subclassing %CSP.WebSocket and defining the Server() method to handle client messages.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement WebSocket communication in InterSystems IRIS?▼

Implement WebSocket communication by subclassing the %CSP.WebSocket class and defining the Server() method to handle incoming client messages over a persistent connection.

What is the difference between synchronous and asynchronous WebSocket servers?▼

Synchronous WebSocket operation processes messages sequentially within the server method, while asynchronous mode allows the InterSystems IRIS server to push data proactively without waiting for client requests.

How does the WebSocket handshake process work?▼

The WebSocket handshake uses an HTTP-based upgrade request to transition a standard HTTP connection into a persistent, full-duplex TCP channel following the RFC 6455 protocol specification.

Can I use WebSockets to build real-time chat and collaborative applications?▼

Yes, WebSockets are ideal for building live chat, real-time stock tickers, and collaborative editing tools because they provide full-duplex, bi-directional communication for immediate data updates.

How do I manage client-side WebSocket connections in JavaScript?▼

Use the JavaScript WebSocket API to create, send, receive, and close connections, establishing a persistent client-server channel that bypasses traditional request-response limitations.

When should I use WebSockets instead of traditional HTTP requests?▼

Use WebSockets when your application requires real-time, server-to-client communication and proactive data pushing, overcoming the limitations of traditional request-response HTTP models.
