Yaya React Native's architecture ke aiki (bridge vs new architecture)?

Question

Accepted Answer

React Native yana aiki da **JavaScript** da **native** code wadanda dole ne su sadarwa. Ainihin architecture yana amfani da asynchronous **bridge**; **new architecture** (JSI, TurboModules, Fabric) yana ba da daidaitawa sauri, synchronous communication. Fahimtar haka yana bayyyana halin React Native da amsawa.

## Ainihin architecture: the bridge

```text
React Native runs:
  → a JS THREAD (your React/JS code) and the NATIVE side (UI, native modules)
  → they communicate over a BRIDGE: messages are SERIALIZED (to JSON), passed ASYNC,
    and deserialized on the other side
Limitations:
  ✗ ASYNCHRONOUS only (can't call native synchronously)
  ✗ SERIALIZATION overhead; the bridge can be a BOTTLENECK with heavy traffic
  ✗ e.g. fast scrolling/animations passing data over the bridge → jank
```

## New architecture (JSI, TurboModules, Fabric)

```text
The NEW ARCHITECTURE replaces the bridge:
  JSI (JavaScript Interface) → JS can call native code DIRECTLY and SYNCHRONOUSLY
    (no serialization bridge) → much faster JS↔native interop
  TURBOMODULES → native modules loaded lazily, via JSI (faster, on-demand)
  FABRIC → the new rendering system → better, more efficient UI rendering; sync layout
  CODEGEN → type-safe JS↔native interfaces
→ Result: better performance, less overhead, synchronous calls, smoother UI.
```

## Yasa yakamata (a zahiri)

```text
→ Explains React Native's PERFORMANCE characteristics (why bridge traffic was costly)
→ The new architecture (default in recent RN) improves performance and interop
→ Informs optimization (minimize bridge crossings on the old architecture; native-thread
  animations) and understanding of how RN executes
```

Fahimtar React Native's architecture ilimin matakin babbar ƙarfe ne saboda yana **bayyana halin React Native da amsawa da amsawa**, tunkarar ƙarfe wajen yin tunani game da kuma inganta apps.

Ainihin tsari — React Native yana aiki da **JS thread** (code naka) da **native side** (UI, native modules) wadanda dole ne su **sadarwa** — shine maɓalli ga fahimtar yaya React Native ke aiki.

Fahimtar **ainihin bridge architecture** (inda JS da native ke sadarwa ta asynchronous bridge wanda ke seriailize jita'a zuwa JSON kuma ke damje su) yana bayyana halin da iyaka na React Native da yada: sadarwa ta asynchronous kawai, yana da seriailize jiya, kuma bridge za ta zama **bottleneck tare da zartacewa mai nauyi** (yana sa jank a cikin sauri sura ko animations wadanda ke damje bayanai) — wanda shine **domin me gatara bridge crossings da aiki animations a native thread mahimman ingantawa**, hadewa architecture zuwa zahirin amfani na ingantawa.

Fahimtar **new architecture** (**JSI** yana ba da kai tsaye, synchronous JS↔native kira ba tare da seriailize bridge; **TurboModules** don shigar da native module don jiya; **Fabric** don inganta render; Codegen don interface masu nuni) yana zama mai matukarici kamar yadda yake zama default — yana inganta amsawa, yana rage jiya, yana ba da daidaitawa ta synchronous kira, da kuma samar da laushi UI, abin wakilta babbar bincike na React Native.

Fahimtar wannan architecture **yana bayyana amsawa na React Native** (domin me bridge ya shaida), **yana ba da shawarar ingantawa** (ayyukan jini daga architecture), kuma yana bayyana yaya React Native ke aiwatar — cewa React Native daga black box zuwa tsarin da za a fahimta.

Tun da fahimtar architecture (the bridge da new JSI-based architecture) yana bayyana halin amsawa na React Native, yana ba da shawarar ingantawa, kuma yana nuna sanuwar bincike na wanda yakamata, kuma tun da wannan zurfin yana cije daga amfani da React Native zuwa fahimta, fahimtar React Native's architecture ilimin matakin babbar ƙarfe ne — yana bayyana halin kuma amsawa, yana ba da shawarar ingantawa, kuma yana nuna zurfin da sanuwar bincike na platform evolution da aka tsammanin ga babbar roles na React Native.
