statepatch
Immer-style ops over a plain JSON tree: observable(initial) wraps one value, .value reads it, and every mutation emits the matching replace / add / remove op to subscribers. Observables compose: one stored inside another mounts its op stream at that path. Part of harness-sdk, under statewire and pinned.
Install
uv add statepatch
Use
from statepatch import observable
state = observable({"runs": []})
state.subscribe(print)
run = observable({"runId": "r1", "queue": []})
state["runs"].append(run) # add op at ["runs", 0]
run["queue"].append({"id": "q1"}) # forwarded as add at ["runs", 0, "queue", 0]
state["runs"].pop(0) # remove op; run is detached and reusable
