produce & reconcile in SolidJS
From the SolidJS cheat sheet · Stores · verified Jul 2026
produce & reconcile
Use produce for mutable-style updates and reconcile for replacing store data.
typescript
// Quick Reference
import { createStore, produce, reconcile } from "solid-js/store";
setState(produce(s => { s.user.name = "Bob"; }));
setState(reconcile(newData));💡 produce lets you write mutable-looking code that produces immutable updates
⚡ reconcile diffs new data against the store to make minimal reactive updates
📌 Use reconcile when replacing store data from API responses for best performance
🟢 produce is imported from "solid-js/store", not from a separate package
