Kepiye arsitektur React Native bisa tindak (jembatan versus arsitektur anyar)?

Question

Accepted Answer

React Native mbukak **JavaScript** lan kode **native** sing kudu komunikasi. Arsitektur asli nggunakake **jembatan** asinkron; **arsitektur anyar** (JSI, TurboModules, Fabric) ngaktifake komunikasi sinkron sing luwih cepet. Ngerti iki njlasake solah lan kinerja React Native.

## Arsitektur asli: jembatan

```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
```

## Arsitektur anyar (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.
```

## Kepiye iki penting (praktis)

```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
```

## Kepiye iki penting

Ngerti arsitektur React Native minangka kawruh tingkat senior sing berharga amarga iku **njlasake solah lan karateristik kinerja React Native**, ndawakaké kemampuan kanggo nalar lan ngoptimalake aplikasi.

Struktur fundamental — React Native mbukak **JS thread** (kodemu) lan **sisi native** (UI, modul native) sing kudu **komunikasi** — minangka kunci kanggo ngerti kepiye React Native bisa tindak.

Ngerti **arsitektur jembatan asli** (nang endi JS lan native komunikasi liwat jembatan asinkron sing serialize pesan menyang JSON lan ngirim liwat) njlasake karateristik kinerja sejarah lan watesan React Native: komunikasi mung asinkron, duwe beban serialisasi, lan jembatan bisa dadi **bottleneck karo lalu lintas abot** (nyebabake jank ing scrolling cepet utawa animasi ngirim data liwat) — sing minangka **kenapa minimal jembatan crossing lan mbukak animasi ing thread native minangka optimisasi penting**, nyambung arsitektur menyang saran kinerja praktis.

Ngerti **arsitektur anyar** (**JSI** ngaktifake langsung, pemanggilan JS↔native sinkron tanpa jembatan serialisasi; **TurboModules** kanggo loading modul native malas; **Fabric** kanggo rendering luwih apik; Codegen kanggo antarmuka type-safe) saya-saya penting amarga dadi default — iku nambahi kinerja, ngurangi beban, ngaktifake panggilan sinkron, lan ngasilake UI luwih mulus, nggawé evolusi React Native sing signifikan.

Ngerti arsitektur iki **njlasake kinerja React Native** (kenapa jembatan penting), **inform optimisasi** (praktik sing teko saka arsitektur), lan njlasake kepiye React Native nglakokake — ngoba React Native saka kotak ireng menyang sistem sing bisa diingerteni.

Amarga ngerti arsitektur (jembatan lan arsitektur JSI-based anyar) njlasake karateristik kinerja React Native, inform optimisasi, lan nglumpukake kesadaran evolusi penting, lan amarga kaluwen iki nambahi saka nggunakake React Native menyang ngerti iku, ngerti arsitektur React Native minangka kawruh tingkat senior sing berharga — njlasake solah lan kinerja, inform optimisasi, lan nglumpukake kaluwen lan kesadaran evolusi platform sing dijajaran kanggo peran React Native senior.
