06 – Lifespan & Shared State

Single PAGI app that handles both lifespan and http scopes:

• Stores a greeting in scope->{state} during lifespan.startup.
• Reuses that state when handling HTTP requests.
• Responds to lifespan.shutdown cleanly.

Quick Start

1. Start the server:

pagi-server --app examples/06-lifespan-state/app.pl --port 5000

You should see startup message in the server logs indicating lifespan initialization.

2. Demo with curl:

# Request uses state initialized during lifespan.startup
curl http://localhost:5000/
# => Hello from lifespan state!

# Make multiple requests - all use the same shared state
curl http://localhost:5000/
curl http://localhost:5000/

3. Test shutdown:

Press Ctrl+C to stop the server and observe the clean shutdown sequence in the logs.
