Kumaha carana men-debug aplikasi React Native?

Question

Accepted Answer

Debugging React Native melibatkan piranti dan teknik kanggo ndiagnosis masalah — **React Native debugger/DevTools**, console logging, **Flipper**, pesan kesalahan, lan debugging khusus platform. Debugging sing efektif minangka keterampilan praktis penting.

## Piranti debugging inti

```text
✓ CONSOLE.LOG → log values/flow (basic but effective; shows in the Metro terminal/debugger)
✓ DEV MENU (shake device / Cmd+D / Cmd+M) → reload, debug, performance monitor, inspector
✓ REACT DEVTOOLS → inspect the component tree, props, state, hooks
✓ DEBUGGER → set breakpoints, step through JS (Chrome DevTools / Hermes debugger / IDE)
✓ ELEMENT INSPECTOR → inspect/tap UI elements to see their styles/hierarchy
```

## Flipper lan piranti liyane

```text
→ FLIPPER → a desktop debugging platform: inspect network requests, logs, layout, state,
  databases, performance (a rich debugging tool for RN)
→ Network debugging → inspect API requests/responses (Flipper, or React Query devtools)
→ Error/red screens → React Native shows errors with stack traces; read them carefully
→ Hermes (the JS engine) debugging tools
```

## Masalah umum lan pendekatan

```text
✓ Read ERROR MESSAGES carefully (red screen stack traces point to the problem)
✓ Isolate the issue (comment out / simplify to find the cause)
✓ Check the JS thread (logs), network (requests), and native logs (Xcode/Android Studio
  Logcat for native-side issues)
✓ Platform-specific bugs → test/debug on BOTH iOS and Android
✓ Performance issues → use the performance monitor / profiler
```

## Apa sebabane penting

Nemahami carane men-debug aplikasi React Native minangka keterampilan praktis penting amarga **masalah mesthi tuwuh** (bugs, errors, perilaku sing ora dikarepake) sing kudu didagnosis, dadi ngerti piranti lan teknik kudu bisa ngerjakan development sing produktif.

React Native development mesthi kalebu debugging, lan nemahami piranti sing kasedhiya minangka kunci.

**Piranti inti** — `console.log` (logging dasar nanging efektif), **menu dev** (reload, pilihan debugging, inspector), **React DevTools** (nginspeksi component tree, props, state, lan hooks — penting kanggo ngerti perilaku component), **debugger** (breakpoints lan stepping through JS), lan **element inspector** (ngsam UI elements lan styles) — nutup kabutuhan debugging fundamental.

Nemahami **Flipper** (platform desktop debugging sing kaya kanggo nginspeksi network requests, logs, layout, state, lan performance) lan network debugging minangka berharga kanggo ndiagnosis API lan data issues sing umum ing apps.

Nemahami **masalah umum lan pendekatan** — maca error messages lan red-screen stack traces kanthi teliti (mulih menyang masalah), ngisolasi issues kanthi simplification, mriksa JS thread, network, lan **native logs** (Xcode/Android Studio Logcat kanggo native-side issues — penting amarga React Native ana JS lan native sides), debugging **platform-specific bugs ing loro platforms**, lan nggunakake performance monitor kanggo performance issues — ngrefleksike debugging sing efektif, sistematis.

Sifat dual JS/native React Native lan aspek cross-platform ndadekake debugging butuh pengetahuan khusus (mriksa loro sides, loro platforms).

Kamangka issues mesthi tuwuh ing React Native development lan debugging sing efektif (nggunakake piranti sing tepat — DevTools, Flipper, logs, native logs — lan pendekatan sistematis, kalebu mriksa loro platforms lan JS lan native sides) kudu ndiagnosis lan ngatasi, nemahami carane men-debug aplikasi React Native minangka keterampilan praktis penting, sering diterapake — kompetensi inti kanggo React Native development sing produktif sing ngobah bugs sing mesthi tuwuh dadi masalah sing bisa dirampungake, kudu kanggo React Native work sing nyata.
