Jinsi modeli wa hali ya MobX unaotofautiana na Redux ilivyo?

**MobX** inachukua njia ya kimsingi tofauti na Redux: badala ya vitendo vya wazi na sasisho lisilobadilika, inatumia **reaktiviti ya uwazi** — unabadilisha hali inayozingatiwa moja kwa moja, na MobX kwa otomati hufuatilia tegemezi na husasisha kila kitu kinachotegemea juu yake (sawa na uhalisi wa Vue au Signals). ## MobX — zingatiaji zenye uweza wa kubadilika, kufuatilia otomati ```js import { makeAutoObservable } from "mobx"; import { observer } from "mobx-react-lite"; class CounterStore { count = 0; constructor() { makeAutoObservable(this); } // make fields observable increment() { this.count++; } // ✅ DIRECT mutation — no actions, no immutability get double() { return this.count * 2; } // computed — auto-derived & cached } const store = new CounterStore(); // observer components auto-re-render when the observables they read change const Counter = observer(() => ( )); ``` Unabadilisha hali moja kwa moja (`this.count++`), na MobX kwa otomati inaonyesha tena tu sehemu za `observer` zinazosome `count`. Hakuna reducers, vitendo, dispatch, au kukamaata kubadilika kwa mikono. ## Tofauti ya msingi ya falsafa ```text Redux MobX Updates immutable (return new state) mutable (change in place) Mechanism explicit actions + reducers transparent reactive tracking Data flow strict one-way, predictable automatic dependency reactions Boilerplate more less Derived values selectors (manual) computed (automatic, cached) Mental model functional / explicit OOP / reactive / implicit ``` ## Jinsi MobX inavyofuatilia tegemezi ```text MobX wraps observables in proxies. When an observer component renders, MobX records which observables it READ. When any of those change, MobX re-runs exactly that component — fine-grained, automatic, no selectors needed. ``` Hii ni wazo lile lile la kufuatilia-kwa-kusoma/kubuza-kwa-kuandika nyuma ya uhalisi wa Vue na Signals. ## Kompromiso ```text MobX pros: less boilerplate, automatic reactivity, easy derived values, OOP-friendly MobX cons: "magic" can be less explicit/traceable than Redux's logged actions; mutation-based flow is harder to time-travel debug than pure reducers ``` ## Kwa nini hii ni muhimu MobX inawakilisha shule ya **reaktivi/inayobadilika** ya udhibiti wa hali — kinyume cha njia ya **wazi/isiyobadilika** ya Redux. Kuelewa kutofautiana kunafahamu mhimili muhimu wa muundo: wazi-na-bahati-kutabiri (Redux: fuatilia kila hatua, lakini boilerplate zaidi) kinyume chaweza-kuweza-otomati (MobX: badilisha kwa uhuru, msimbo mdogo, lakini zaidi ya wazi). Nadharia sawa ya kufa iliyoundwa iko nyuma ya Vue na Signals, kwa hiyo kuelewa MobX kunaangazia familia nzima ya zana za hali na kukusaidia kuchagua kati ya ubahati-kutabiri na ergonomiki kwa mradi fulani.
