Examples

Try them live at http-nu.cross.stream/examples/.

Running all examples

The examples hub mounts individual examples under one server:

http-nu --datastar :3001 examples/serve.nu

With a store (enables quotes):

http-nu --datastar --store ./store :3001 examples/serve.nu

Then visit http://localhost:3001.

Local dev: add --dev when running over plain HTTP. Examples that set cookies (2048's session cookie, for instance) default to Secure, so the browser drops them on http://localhost. --dev omits the Secure flag.

Individual examples

Each example can also be run standalone.

Store-dependent examples

Quotes and the /topic route in templates require --store. The hub detects $HTTP_NU.store at runtime and greys out unavailable examples. When --store is provided, templates automatically seeds its topics on startup.
