A curated collection of mostly handcrafted skills encoding more than a decade of best practices, proven patterns, and lessons learned for Angular frontend development, from SaaS MVPs to enterprise-scale environments.

Skills

Angular Enterprise Architecture

Guidance for building and evolving maintainable, extendable enterprise-grade Angular applications with a standalone-first architecture, isolated lazy business features, reusable ui and pattern building blocks, one-way dependency graph rules, and tooling-based automated architecture validation.

Based on the Angular Enterprise Architecture eBook by Tomas Trajan @tomastrajan, this skill translates the book's proven Angular architecture approach into agent-ready rules for new projects, existing project improvements, and long-term consistency across teams.

Handles:

• Placement decisions for core, layout, ui, feature, pattern, app/helper building blocks, and libraries.
• Lazy feature isolation, nested lazy sub-features, and the extract-one-level-up rule.
• Standardized building block definitions and dependency allow rules.
• Reusable eslint-plugin-boundaries config for IDE and CI-based architecture validation.
• Repeatable patterns for sharing code without breaking lazy loading, feature isolation, or the one-way dependency graph.

NgRx

Guidance for implementing and modifying NgRx state management in Angular applications. Predictable state. Scalable apps. Composable, performant, and built for Angular.

Handles:

• State management architecture, read/write boundaries, and container/UI component responsibilities.
• State modeling, serializability, and error modeling.
• Global store setup and runtime checks.
• State slices, lazy feature boundaries, and slice extraction.
• Selectors and state consumption in container components.
• Reducers and immutable state updates.
• Effects for backend requests, navigation, deep linking, URL synchronization, scrolling, and route-driven data loading.
• NgRx router-store registration and router selector factories.
• Observable data sources exposed through selectors.
