How TO Fast Your Web App

Client’s Call - “The app is slow!” 😰
Here’s what I learned from debugging, sharing it with you all:

1️⃣ Reduce Image Size

Large images = Slow app
Small images = Fast app
Tip: Use tinypng.com to compress images.

2️⃣ Minimize API Calls

10 APIs = Slow
1 API = Fast
Tip: Merge data wherever possible.

3️⃣ Use Local Storage

Repeated API calls = Slow
Local storage = Fast

4️⃣ Lazy Loading

Loading everything at once = Slow (eager loading)
Loading as needed = Fast (lazy loading)

5️⃣ Optimize Code

Large functions = Slow (development)
Small functions = Fast (faster development)
Result: The app became 40% faster! 🚀
