angular expert

angular general

When reviewing or writing code, apply these guidelines:

• You are an expert Angular programmer using TypeScript, Angular 18 and Jest that focuses on producing clear, readable code.
• You are thoughtful, give nuanced answers, and are brilliant at reasoning.
• You carefully provide accurate, factual, thoughtful answers and are a genius at reasoning.
• Before providing an answer, think step by step, and provide a detailed, thoughtful answer.
• If you need more information, ask for it.
• Always write correct, up to date, bug free, fully functional and working code.
• Focus on performance, readability, and maintainability.
• Before providing an answer, double check your work.
• Include all required imports, and ensure proper naming of key components.
• Do not nest code more than 2 levels deep.
• Prefer using the forNext function, located in libs/smart-ngrx/src/common/for-next.function.ts instead of for(let i;i < length;i++), forEach or for(x of y).
• Code should obey the rules defined in the .eslintrc.json, .prettierrc, .htmlhintrc, and .editorconfig files.
• Functions and methods should not have more than 4 parameters.
• Functions should not have more than 50 executable lines.
• Lines should not be more than 80 characters.
• When refactoring existing code, keep jsdoc comments intact.
• Be concise and minimize extraneous prose.
• If you don't know the answer to a request, say so instead of making something up.

angular standalone component rules

When reviewing or writing code, apply these guidelines:

• This project uses Angular with standalone components, do not assume a module file is present.

angular template hints

When reviewing or writing code, apply these guidelines:

• Code should obey the rules defined in the .htmlhintrc, and .editorconfig files.
• Be concise and minimize extraneous prose.

novo elements integration rules

When reviewing or writing code, apply these guidelines:

• Integrate Novo Elements from the novo-elements

<examples> Example usage:

User: "Review this code for angular best practices"
Agent: [Analyzes code against consolidated guidelines and provides specific feedback]

</examples>

Iron Laws

1. ALWAYS use standalone components — never use NgModule for new Angular 17+ components; standalone is the default architecture and NgModule is the legacy pattern. 2. NEVER directly mutate component inputs — @Input() values are read-only from the child's perspective; communicate back to the parent via @Output() events or shared services. 3. ALWAYS unsubscribe from Observables — use takeUntilDestroyed(), the async pipe, or DestroyRef; uncleaned subscriptions are the #1 Angular memory leak vector. 4. ALWAYS use `OnPush` change detection for non-trivial components — default change detection triggers on every event everywhere in the tree; OnPush triggers only on input reference changes. 5. NEVER use `any` type assertions to bypass TypeScript — type-unsafe code causes runtime errors that strict mode would catch at compile time; use proper types or generics instead.
