Apa iku modul native ing React Native?

Question

Accepted Answer

**Modul native** ngidini React Native (JavaScript) ngakses **kode platform native lan fitur-fitur** (iOS/Android) sing ora bisa diakses melalui JavaScript — menjembatani ke API native, SDK, utawa fungsionalitas native khusus. Iku nggelar React Native lampah saka apa sing bisa diwatani JS dhewé.

## Alasan modul native ana

```text
React Native's JavaScript can't directly access every native capability. NATIVE MODULES
bridge JS to native code (Swift/Objective-C on iOS, Kotlin/Java on Android):
  → access native APIs/SDKs not exposed to JS
  → use existing native libraries
  → implement performance-critical or platform-specific functionality in native code
→ The bridge between React Native's JS and the native platform.
```

## Nggunakake modul native (umume liwat perpustakaan)

```text
→ MOST native functionality is available via EXISTING LIBRARIES (npm packages that
  include native modules): camera, geolocation, Bluetooth, payments, push notifications, etc.
  → you usually INSTALL a library rather than writing native code yourself
→ EXPO provides many native APIs without writing native code (managed modules)
→ You WRITE a custom native module only when no library exists for your need
```

## Nulis modul native khusus (konsepsional)

```text
→ Write native code (Swift/Kotlin) exposing methods to JS
→ Register/expose it so JS can call it (via the bridge / new architecture's TurboModules)
→ Call it from JavaScript like a regular module
→ Requires native development knowledge; platform-specific implementation per OS
→ The NEW ARCHITECTURE (JSI, TurboModules, Fabric) improves native interop performance
```

## Apa sing penting

Pangerten modul native iku berharga amerga iku **carane React Native ngakses kemampuan platform native** sak sauran apa sing diwatani JavaScript, kapabilitas penting kanggo aplikasi sing butuh fitur native, dadi pangerten sing berguna kanggo pangembangan React Native.

Kebutuhan inti — JavaScript React Native ora bisa langsung ngakses saben kemampuan native, dadi **modul native menjembatani JS menyang kode native** (Swift/Objective-C, Kotlin/Java) — ngatasi carane React Native ngakses fitur piranti (kamera, geolokasi, Bluetooth, push notifications), nggunakake SDK native, lan ngimplementasiake fungsionalitas sing kritis kanggo performa utawa spesifik platform.

Pangerten **kasunyatan praktis** iku penting: **umume fungsionalitas native ana ing perpustakaan sing wis ana** (paket npm sing ngebundle modul native) utawa **API native sing dikelola Expo**, dadi biasane **nasedhiake perpustakaan ketimbang nulis kode native dhewé** — tegese umume pangembang ngonsumsine modul native liwat perpustakaan ketimbang nulis, poin praktis penting sing nyetel ekspektasi sing realistis.

Pangerten yen sampeyan **nulis modul native khusus mung yen ora ana perpustakaan** kanggo kebutuhan spesifik sampeyan (mbutuhake pangerten pangembangan native lan implementasi per-platform) iku nerangake kapan kerja native khusus dibutuhake.

Ngerti yen **arsitektur baru** (JSI, TurboModules, Fabric) ningkatake performa interop native nggambarake kabare evolusi React Native.

Modul native iku carane React Native ngikat karo platform native, penting kanggo aplikasi sing duwe kebutuhan native, nanging umume kebutuhan bisa dipenuhi perpustakaan sing wis ana.

Karene ngakses kemampuan native mestine dibutuhake (kanggo fitur piranti lan integrasi native) lan modul native (umume liwat perpustakaan, kadang-kadang khusus) iku mekanisme React Native kanggo kuwi, lan karana pangerten carane iku bisa lan yen umume kebutuhan bisa dipenuhi perpustakaan sing wis ana iku berharga kanggo pangembangan React Native, pangerten modul native iku berharga, pangerten sing relevan kanthi praktis — menjembatani sing ngidini React Native ngakses fitur native, penting kanggo aplikasi sing duwe kebutuhan native sekaligus nerangake yen umume fungsionalitas teka saka perpustakaan sing wis ana ketimbang kode native khusus, konteks sing berguna kanggo gawé karo kemampuan native React Native.
