Fabrics

A Fabric is the substrate a Ref lives on. One page per Fabric: the Refs it ships, the Interactions on top of them, the shape of what it stores.

Fabric	Module	What
kv	`nu.kv`	Virtual collections over any KV backend. Persistent, paged, view-composable.
ui	`nu.ui`	Reactive UI fabric: shape trees rendered live in the browser.
cluster	`nu.cluster`	Distributed fabric backed by Ray actors and object refs.
llm	`nu.llm`	OpenAI-compatible chat fabric: one wire, N providers.
mem	`nu.mem`	In-process fabric: plain nested Python dicts as the data bag. Zero setup.
proxy	`nu.proxy`	Proxy fabric: transparent remote objects, local calls, remote execution.
http	`nu.http`	HTTP fabric: expose Nu Refs as endpoints, or build on top of any HTTP service.
service	`nu.service`	In-process service fabric: any Python object as a tree of Refs.
cc	`nu.cc`	Claude Code as a Ref: prompts from your Nu tree, session brackets, text and metadata back.
mp	`nu.mp`	Local multiprocessing fabric: teleport subtrees onto spawned worker processes.
