Angular Expert

Master modern Angular development with Signals, Standalone Components, Zoneless applications, SSR/Hydration, and the latest reactive patterns.

Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

When to Use This Skill

• Building new Angular applications (v20+)
• Implementing Signals-based reactive patterns
• Creating Standalone Components and migrating from NgModules
• Configuring Zoneless Angular applications
• Implementing SSR, prerendering, and hydration
• Optimizing Angular performance
• Adopting modern Angular patterns and best practices

Do Not Use This Skill When

• Migrating from AngularJS (1.x) → use angular-migration skill
• Working with legacy Angular apps that cannot upgrade
• General TypeScript issues → use typescript-expert skill

Safety

• Always test changes in development before production
• Gradual migration for existing apps (don't big-bang refactor)
• Keep backward compatibility during transitions

---

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Example boundaries

Examples are fragments and omit project imports/types/components such as ItemComponent, HeaderDirective, User and Product; supply their actual definitions. effect and toSignal need an injection context or explicit injector. Route guards improve navigation UX but every server endpoint must enforce authorization; validate returnUrl as an allowed internal route. Do not log real form or account data.

Use template imports and semantic labels/alt text in complete components. Replace the image placeholder with an actual supported data URL or configured loader. Product loading needs cancellation/stale-response handling, error state and lifecycle policy for repeated calls. Read-only signals do not deeply freeze objects. Constructor injection and @Input remain supported patterns; migrate for a concrete benefit. Configure SSR state/cache providers per request to avoid cross-user leakage.
