How to think about CDN in the F999 Guide

1. Identify the file first

If you see where an HTML file, a JS file, and a few images load from, you'll notice that reducing unnecessary requests makes a difference even on Dhaka's slow network.
2. Separate caching

Keeping static files and changing content under the same rules makes things harder; header setting is easier with open-source tools.
3. Minify JavaScript

Smaller bundles; follow this principle: removing unused code makes the F999 App pages respond faster.
4. Measure results

With Chrome DevTools and Lighthouse, you can check the state in 3 minutes, then tune critical flows like the bKash or Nagad page separately.

6 notable notes of the week

CDN hit rate

If the cache hit rate is good, JS isn't fetched repeatedly, reducing mobile load time.

Open-source library

Using community-maintained packages makes updates easier; also check licenses first.

JavaScript events

Remove unnecessary listeners; UI feels snappy with small code, big benefits.

Dhaka network

Afternoon load times may be a bit slower, so sending critical assets first is good

bKash flow

Keep redirects low on the payment page; Nagad and Rocket users also want the same ease.

F999 App

If the APK file is lightweight, installation is faster; new users spend less time setting up.
