React Native

Warpcast

These past couple of weeks I've been focused on making the Warpcast app feel faster.

There is still more room for improvement but I'm happy to say that we've been able to move the needle.

We did this by:
- parallelizing more requests in the background
- tweaking when we issue certain requests
- lazy loading data into lists
- lazy loading large resources such as videos

We can already see improvements in some charts that haven't been easy to move before.

I'm particularly happy that my Android feed loads much better as seen in the before and after videos in the replies.

Please let me know if you see improvements and especially if you encounter any issues.

good perf in React Native doesn’t come for free. this is cool work!!

I wonder what tool they are using to measure performance
