Hazina nyingi kama Zustand na Jotai zinatofautiana vipi na Redux?

Question

Accepted Answer

**Zustand** na **Jotai** ni maktaba ya hali ndogo ambayo inafikia hali ya kimataifa kwa boilerplate kidogo zaidi kuliko Redux, na kwa **usajili wa uteuzi** iliyojengwa ili kuepuka upya-ukaaji usiotakikia. Zinachukua mifumo mbalimbali ya akilini: Zustand ni duka moja; Jotai ni kimatomiki. ## Zustand — duka rahisi linalotegemea hook ```jsx import { create } from "zustand"; // define a store: state + the actions that update it, all in one place const useStore = create((set) => ({ count: 0, increment: () => set((s) => ({ count: s.count + 1 })), // no actions/reducers/dispatch reset: () => set({ count: 0 }), })); function Counter() { const count = useStore((s) => s.count); // SELECT — re-renders only when count changes const increment = useStore((s) => s.increment); return ; } ``` Hakuna mtoaji, hakuna vitendo, hakuna vipunguza, hakuna kupeleka — unakutana na kazi za kuweka moja kwa moja. Kichagua (`s => s.count`) kinamaanisha kwamba kijenzi kinachukuliwa upya *tu* wakati sehemu hiyo inabadilika. ## Jotai — hali ya kimatomiki ```jsx import { atom, useAtom } from "jotai"; const countAtom = atom(0); // a tiny piece of state const doubleAtom = atom((get) => get(countAtom) * 2); // derived atom function Counter() { const [count, setCount] = useAtom(countAtom); // works like useState, but GLOBAL return ; } ``` Jotai inajengea hali kutokana na **atomi** ndogo unayochanganya; vijenzi vinajisajili kwa atomi za kibinafsi na kunukiwa upya tu wakati hizo atomi mahsusi zinabadilika. ## Kulinganisha na Redux ```text Redux (classic) Zustand Jotai Boilerplate high (actions/reducers) very low very low Provider required none minimal Mental model single store + dispatch single store, hooks atomic (useState-like) Re-renders needs selectors selector built-in per-atom (granular) Devtools excellent good good Bundle size larger tiny (~1KB) tiny ``` ## Wakati wa kuchagua nini ```text Zustand → simple global state, minimal ceremony (most apps' global needs) Jotai → bottom-up/granular state, lots of independent pieces, derived values Redux(RTK) → very large apps, strict structure, rich devtools/middleware ecosystem ``` ## Kwa nini ni muhimu Zustand na Jotai zinawakilisha mwelekeo wa kisasa kutoka kwa boilerplate ya Redux kuelekea hali ya **kidogo, rafiki-ikiambatanisha** inayohusiana kwa jumla na usajili wa uteuzi iliyojengwa (kusuluhisha tatizo la upya-ukaaji wa Context). Kujua kwamba zipo — na kwamba Zustand inatoa mfano mdogo wa duka moja lakini Jotai inatoa atomi zinazopatikana — inakuruhusu kuchagua zana nyingi zinazolingana na mahitaji ya hali ya kimataifa ya zaidi ya matumizi, na kukamatia Redux Toolkit nzito kwa programu kubwa, changamano. Faida kuu inayoshirikiana juu ya Context ni usajili wa kina ambao unazuia upya-ukaaji wa kupita kiasi.
