Contents and terms

Follow progress as it happens

This starter connects a Node.js 24 server to an HTML/CSS/JavaScript interface through EventSource. It streams original example steps, displays progress and lets the visitor stop the stream cleanly.

Bounded connections

The server limits connections, lifetime and slow-reader waits. Heartbeats and disconnect cleanup are included. Events are educational: durable history, private access and automatic resumption are not provided.

Included capabilities

Progress interface and stop control
Structured events and heartbeats
Disconnect cancellation
Bounded lifetime and connections
Real local HTTP tests
