Overview

Reusable Angular UI architecture designed to provide a shared foundation for forms, inputs, layouts, tables, dialogs, navigation and other enterprise application patterns.

The challenge

Large applications often develop duplicated UI patterns, inconsistent interactions and difficult-to-maintain components as multiple teams build features independently.

Reusable components must remain flexible enough for different business requirements without becoming overly complex or tightly coupled to individual applications.

The solution

A reusable Angular component architecture focused on consistency, composability, accessibility, scalable APIs and predictable design patterns across enterprise applications.

Standalone Angular components with reusable APIs, Signals for reactive state, Angular CDK capabilities where required and Tailwind CSS for consistent design tokens and styling patterns.

Key features

  • Reusable Angular components

  • Form controls

  • Input components

  • Buttons and actions

  • Tables and data views

  • Dialogs and overlays

  • Layout components

  • Navigation patterns

  • Design tokens

  • Accessibility patterns

Engineering decisions

decision.md
Problem
Shared components fail in two opposite directions — too rigid and teams work around them, too configurable and they become harder to use than writing the markup directly.
Decision
Standalone components with small, composable APIs and Signals for reactive state, rather than large components with wide option surfaces.
Why
Composition lets a team assemble the variant they need from parts that each stay simple, which keeps flexibility without pushing every new requirement into another boolean input.
Trade-off
Composable parts mean more pieces to learn and more assembly at the call site than a single component that tries to do everything.
decision.md
Problem
Interaction behaviour — focus management, overlays, keyboard handling — is the part teams most often reimplement slightly differently and slightly wrong.
Decision
Angular CDK primitives underneath the component layer wherever that behaviour is needed, rather than hand-rolled implementations per component.
Why
These are solved problems with accessibility requirements attached, and a bespoke version is usually a subtly inaccessible version.
Trade-off
It ties the component layer to CDK conventions and adds a dependency that has to be upgraded in step with Angular.

Results

  • Planned: a reusable UI foundation for enterprise Angular applications.
  • Planned: standardise frequently used interface patterns to reduce duplication.
  • Planned: a scalable approach to keeping application experiences consistent.
