Build an Ext JS UI/UX abstraction layer

Context

In addition to backend data exchange, I also worked on internal systems built primarily with Ext JS.

Enterprise systems contained many similar UI patterns:

• Grid
• Form
• Query
• Toolbar
• Dialog
• CRUD Flow

Business data differed by feature, but many interaction patterns were highly similar.

If every screen recomposed components, events, and data operations, different modules could easily develop their own implementation styles over time.

My Decision & Action

During development, I therefore organized recurring UI/UX behavior into a reusable abstraction layer.

Rather than simply dividing screens into common components, I tried to separate:

The fixed interaction model

and

The business content that truly differed for each feature

from one another.

Common patterns such as queries, form operations, window control, and data presentation could be composed consistently without every feature rebuilding its own workflow.

Outcome

Similar features could follow the same UI/UX patterns.

Besides reducing duplicated implementation, this made interaction and code structure more consistent across modules and easier to extend when adding features.

Reflection

This was when I first began to realize:

The value of abstraction is not merely writing fewer lines of code, but preventing the same problem from producing many different solutions within a system.

This idea later extended into how I think about components, Shared Packages, architecture, and engineering rules.
