This stuff isn't in YouTube tutorials.

You learn it by watching real users complain about lag.

What's your favorite RN performance trick?

Pro tip 💡

Open RN performance monitor:
Dev menu → Show Perf Monitor

JS thread green but UI thread red?
= Bridge congestion

This is what shipping apps to 100K+ users teaches you 😅

Real performance wins aren't in your React code.

They're in understanding the architecture underneath.

Clean JavaScript won't help if you're flooding the bridge with unnecessary communications.

[Akam peter @Akam_peter001]

✅ Solution 4: Embrace the new architecture

Fabric + TurboModules remove the bridge entirely.

JSI (JavaScript Interface) enables synchronous native calls.

The future of RN performance is here.

[Akam peter @Akam_peter001]

✅ Solution 2: Batch state updates
Don't update on every scroll event. Use requestAnimationFrame or throttle.

✅ Solution 3: Keep heavy computations OFF the JS thread
Use native modules for image processing & complex calculations.

[Akam peter @Akam_peter001]

✅ Solution 1: Use native drivers

Animated.timing(fadeAnim, {
toValue: 1,
useNativeDriver: true, // Runs on UI thread
})

This bypasses the bridge entirely.

[Akam peter @Akam_peter001]

Every time you do this:

this.setState({
scrollY: event.nativeEvent.contentOffset.y
})

You're sending serialized JSON across the bridge.

60 times per second during scroll.

The bridge becomes a highway traffic jam 🚗🚗🚗

[Akam peter @Akam_peter001]

React Native has 3 threads:

1️⃣ JavaScript thread (business logic)
2️⃣ Native/UI thread (renders UI)
3️⃣ Shadow thread (calculates layout)

They communicate through THE BRIDGE — a serialization bottleneck.

I see this ALL the time:

- Developer adds useMemo everywhere
- Wraps everything in useCallback
- Reduces re-renders to zero

App still lags. UX still choppy.

Why? They're optimizing the wrong thing.

[Akam peter @Akam_peter001]

Your React Native app isn't slow because of JavaScript.

It's slow because of the bridge.

Here's what 90% of developers get wrong about RN performance 🧵

@raumafrica I can't hear anything anymore, is it just me?

Just tested the @finnaprotocol web app from end to end (signup to loan disbursement)! :tada:

Smooth stuff!

You don't have to sell your USDT for naira anymore. Stake it for local fiat.
