Building Enterprise Mobile Apps? Avoid This Common Mistake

One mistake I keep seeing in enterprise Mobile Application Development :

Building apps by stitching together too many libraries.

Typical setup looks like:

UI > React/Vue
Data grid > separate library
Charts > another library
State > another tool

It works… until it doesn’t.

What breaks first?
Large datasets > performance issues
UI consistency > starts drifting
Maintenance > becomes painful
Dev onboarding > slower
What actually helps

Using a more integrated approach:

Pre-built UI components
Unified data layer
Consistent layout system
Built-in performance optimizations

Especially important for Sencha ExtJS if your app includes:

Dashboards
Reporting tools
Real-time data
Complex workflows
My takeaway

If you’re building something small > lightweight stack is fine.
If you’re building enterprise apps > architecture matters more than speed.
