nustd

Batteries for Nu.

nucore is the kernel: the language, the engine, the core atoms, flows, spans, forms, the tree rewrites, nu.prog, nu.inspect. It has no fabric backends in it. The nu command lives in nucli.

nustd is everything that talks to the outside world. One import, then dot-access: import nustd, then nustd.kv, nustd.ui, nustd.uuid.

Fabric Extra What it is
nustd.service - Service / method dispatch
nustd.mem nustd[mem] In-process refs
nustd.kv nustd[kv] Key-value storage (virtuals, RocksDB)
nustd.ui nustd[ui] The nudle web UI runtime
nustd.llm nustd[llm] LLM calls
nustd.cc nustd[cc] Claude Agent SDK sessions
nustd.http nustd[http] HTTP client atoms
nustd.proxy nustd[proxy] Remote objects over invisibles
nustd.mp nustd[mp] Multiprocessing workers
nustd.cluster nustd[cluster] Ray

The standard library sits at the same level, one module per Python stdlib module it mirrors: nustd.uuid, nustd.datetime, nustd.decimal, nustd.math, nustd.pathlib, nustd.logging, nustd.fin and the rest. No extra needed, they are pure Nu.

Install

pip install nustd[all]      # everything
pip install nustd[kv,ui]    # just what you need

nucore comes along as a dependency. Add nucli for the nu command: pip install "nustd[all]" nucli.

Released in lockstep with nucore and nucli. Docs at nustack.dev.
