# SOLID Design Principles - Coding Assistant Guidelines

When generating, reviewing, or modifying code, follow these guidelines to ensure adherence to SOLID principles:

## 1. Single Responsibility Principle (SRP)

- Each class must have only one reason to change.
- Limit class scope to a single functional area or abstraction level.
- When a class exceeds 100-150 lines, consider if it has multiple responsibilities.
- Separate cross-cutting concerns (logging, validation, error handling) from business logic.
- Create dedicated classes for distinct operations like data access, business rules, and UI.
- Method names should clearly indicate their singular purpose.
- If a method description requires "and" or "or", it likely violates SRP.
- Prioritize composition over inheritance when combining behaviors.

## 2. Open/Closed Principle (OCP)

- Design classes to be extended without modification.
- Use abstract classes and interfaces to define stable contracts.
- Implement extension points for anticipated variations.
- Favor strategy patterns over conditional logic.
- Use configuration and dependency injection to support behavior changes.
- Avoid switch/if-else chains based on type checking.
- Provide hooks for customization in frameworks and libraries.
- Design with polymorphism as the primary mechanism for extending functionality.

## 3. Liskov Substitution Principle (LSP)

- Ensure derived classes are fully substitutable for their base classes.
- Maintain all invariants of the base class in derived classes.
- Never throw exceptions from methods that don't specify them in base classes.
- Don't strengthen preconditions in subclasses.
- Don't weaken postconditions in subclasses.
- Never override methods with implementations that do nothing or throw exceptions.
- Avoid type checking or downcasting, which may indicate LSP violations.
- Prefer composition over inheritance when complete substitutability can't be achieved.

## 4. Interface Segregation Principle (ISP)

- Create focused, minimal interfaces with cohesive methods.
- Split large interfaces into smaller, more specific ones.
- Design interfaces around client needs, not implementation convenience.
- Avoid "fat" interfaces that force clients to depend on methods they don't use.
- Use role interfaces that represent behaviors rather than object types.
- Implement multiple small interfaces rather than a single general-purpose one.
- Consider interface composition to build up complex behaviors.
- Remove any methods from interfaces that are only used by a subset of implementing classes.

## 5. Dependency Inversion Principle (DIP)

- High-level modules should depend on abstractions, not details.
- Make all dependencies explicit, ideally through constructor parameters.
- Use dependency injection to provide implementations.
- Program to interfaces, not concrete classes.
- Place abstractions in a separate package/namespace from implementations.
- Avoid direct instantiation of service classes with 'new' in business logic.
- Create abstraction boundaries at architectural layer transitions.
- Define interfaces owned by the client, not the implementation.

## Implementation Guidelines

- When starting a new class, explicitly identify its single responsibility.
- Document extension points and expected subclassing behavior.
- Write interface contracts with clear expectations and invariants.
- Question any class that depends on many concrete implementations.
- Use factories, dependency injection, or service locators to manage dependencies.
- Review inheritance hierarchies to ensure LSP compliance.
- Regularly refactor toward SOLID, especially when extending functionality.
- Use design patterns (Strategy, Decorator, Factory, Observer, etc.) to facilitate SOLID adherence.

## Warning Signs

- God classes that do "everything"
- Methods with boolean parameters that radically change behavior
- Deep inheritance hierarchies
- Classes that need to know about implementation details of their dependencies
- Circular dependencies between modules
- High coupling between unrelated components
- Classes that grow rapidly in size with new features
- Methods with many parameters

You have a short session-based memory, so you can use the memory tools (if present) to persist/access data between sessions. Use memory to store insights, notes, and context that is especially valuable for quick access.

- Follow React patterns
- Avoid prop drilling

- Look for potential attack vectors in the code provided
- Ask users to provide more context (for example imported files etc) when needed
- Look for ways the system could be misused
- Always explain the reasoning behind security concerns
- Provide practical, context-appropriate solutions
- Keep OWASP Top 10 in mind
- Remember that security is about tradeoffs
- If you are unsure about something, ask for more context
- DO NOT ASSUME YOU KNOW EVERYTHING, ASK THE USER ABOUT THEIR REASONING

# Next.js Security Best Practices

## Data Validation and Input Handling
- **Always validate user inputs with schemas**
  - ❌ Directly using req.body in API handlers without validation
  - ✅ Using schema validation libraries to validate request bodies before processing them

- **Sanitize rendered content**
  - ❌ Using dangerouslySetInnerHTML with unsanitized content
  - ✅ Using a sanitization library to clean HTML or avoiding direct HTML insertion

- **Be careful with dynamic imports**
  - ❌ Using unvalidated user input for dynamic imports or file paths
  - ✅ Strictly validating and limiting what can be dynamically imported

## API Routes and Server Security
- **Separate API route handlers from page components**
  - ❌ Using fetch with sensitive operations directly in client components
  - ✅ Creating separate API route handlers and calling them from client components

- **Secure API routes with proper authentication**
  - ❌ Creating API routes that don't verify auth status before performing operations
  - ✅ Checking auth status at the beginning of API handlers and returning 401/403 when needed

- **Implement proper CSRF protection**
  - ❌ Creating custom API endpoints without CSRF tokens for state-changing operations
  - ✅ Using form actions with built-in CSRF protection or adding CSRF tokens to custom APIs

- **Use proper error handling in API routes**
  - ❌ Returning full error details: `return res.status(500).json({ error: err.stack })`
  - ✅ Logging detailed errors server-side but returning generic messages to clients

- **Implement rate limiting**
  - ❌ Allowing unlimited requests to sensitive endpoints
  - ✅ Using rate limiting middleware or implementing custom rate limiting

## Environment and Configuration Security
- **Use environment variables correctly**
  - ❌ Adding API keys with NEXT_PUBLIC_ prefix or hardcoding them in client components
  - ✅ Using process.env.API_KEY in server components or API routes only

- **Set appropriate Security Headers**
  - ❌ Leaving default security headers without customization
  - ✅ Using the Next.js headers configuration to set appropriate security policies

## Data Storage and Transmission
- **Avoid client-side secrets in redirects**
  - ❌ Redirecting with sensitive data in query params: `router.push(/success?token=${token})`
  - ✅ Using cookies or session storage for sensitive data during redirects

- **Secure cookies configuration**
  - ❌ Setting cookies without security attributes
  - ✅ Using appropriate httpOnly, secure, and sameSite attributes for sensitive data

## Content and File Security
- **Beware of metadata injection**
  - ❌ Using unvalidated user input directly in page metadata
  - ✅ Sanitizing or validating any user-provided data used in metadata

- **Secure file uploads**
  - ❌ Accepting any file upload without validation
  - ✅ Implementing strict validation for file types, sizes, and content

## Advanced Protections
- **Protect against prototype pollution**
  - ❌ Deep merging objects from untrusted sources without sanitization
  - ✅ Using Object.create(null) or dedicated libraries for safe object merging

- Always write valid TypeScript code

I am using Next.js, along with the following tools:
- Vercel
- TypeScript
- Zod
- shadcn
- Tailwind
- clsx
- PostgreSQL
- pnpm

## Build & Development Commands - Ensure `.gitignore` is present and up to date based on project language/toolchain.
## Testing Guidelines - Recommend committing test cases alongside features or fixes.
## Code Style & Guidelines  - Use consistent formatting tools (e.g., Prettier, Black) pre-commit if available.
## Documentation Guidelines  - Include changelogs or commit logs for release notes.
## Git Rules - Use clear commit messages: `<type>: <what>` (e.g., `fix: resolve header overlap`). - Squash trivial commits when possible before merging. - Warn users when suggesting force pushes or rebase.

# JavaScript AI Assistant Ruleset

## Technical Requirements
1. Write modern JavaScript code (ES6+) that follows current best practices.
2. Always implement proper error handling with try/catch blocks when appropriate.
3. Include comments for complex logic, function parameters, and return values.
4. Optimize solutions for performance regarding CPU usage, memory consumption, and execution time.

8. Adapt explanations and solutions based on the user's demonstrated skill level.
9. Suggest alternative approaches for complex problems, explaining tradeoffs.
10. Provide complete solutions including necessary imports, function definitions, and usage examples.

## Framework and Ecosystem Awareness
11. Respect the user's chosen framework or library; don't suggest React solutions for Angular projects.
12. Maintain current knowledge of major frameworks, libraries, tools, and their best practices.
13. Note version compatibility issues when solutions require specific Node.js/npm versions.
14. Consider full-stack implications when JavaScript solutions interact with backend services.

21. Prioritize readability over clever or overly concise code.
22. Suggest proper error messages that are informative and actionable.
23. Recommend appropriate logging for debugging and monitoring.
24. Favor immutability and pure functions when appropriate.

## Development Guidelines
- Wrap everything in a single named export default function (e.g., export default function MyPage() { ... }).
- Include mock or placeholder data if the backend is not specified.
- If fetching data, simulate using useEffect with setTimeout or fetch() with sample endpoints.
- Always handle loading and error states if data is involved and provide a human-readable console.log with a description of errors.
- Avoid global state unless specified — stick with useState or useReducer.
- Prefer composition over repetition — break large components into reusable ones if logic is repeated.
- For interactive UI, use react-bootstrap and for styling use Tailwind CSS
- Use clean, readable layouts: flexbox or grid where needed.
- Use accessible HTML semantics (<section>, <header>, <nav>, <main>, <footer>, etc.).
- Make it responsive by default (e.g., max-w, px-4, sm: prefixes).
- The result should be self-contained and easy to copy-paste into a file like MyPage.jsx.
- No unnecessary imports, only include what’s used.
- Add a brief comment block at the top describing what the page does (optional).
- Use arrow functions for helpers inside the component (const handleClick = () => {}).
- Use descriptive variable and function names (no foo, bar, etc.).
- Use JSX fragments (<>...</>) where needed instead of wrapping everything in a div.

# AI Assistant Instructions for Node.js Projects

You are an expert in Node.js development with a focus on writing clean, maintainable, and efficient code. Follow these rules when generating or editing code:

## Core Principles
- Write modern JavaScript using ES6+ syntax (e.g., const, let, arrow functions, async/await).
- Prioritize simplicity, readability, and scalability in all solutions.
- Avoid unnecessary complexity or over-engineering.
- Use functional programming patterns where appropriate; avoid classes unless required.
- Ensure all code is modular and follows the single-responsibility principle.

## Code Style
- Use 2-space indentation.
- Use single quotes for strings unless escaping is needed.
- Avoid semicolons unless required for clarity (e.g., to avoid ASI issues).
- Use camelCase for variable and function names (e.g., `getUserData`).
- Use descriptive variable names with auxiliary verbs where applicable (e.g., `isLoading`, `hasError`).
- Always use strict equality (`===`) over loose equality (`==`).

## Node.js Specific Guidelines
- Use `async/await` for asynchronous operations instead of callbacks or raw Promises.
- Handle errors explicitly with try/catch blocks in async functions.
- Export modules using CommonJS (`module.exports`) unless the project uses ES Modules (`export`).
- Organize code into separate files/folders (e.g., `routes/`, `controllers/`, `utils/`).
- Use `process.env` with the `dotenv` package for environment variables.

## Project Structure
- Place the main application entry point in `app.js` or `index.js`.
- Store route definitions in a `routes/` directory (e.g., `routes/index.js`).
- Keep utility functions in a `utils/` directory.
- Serve static files from a `public/` directory if applicable.

## Error Handling
- Always include error handling in API routes and middleware.
- Return meaningful error messages with appropriate HTTP status codes (e.g., 400, 404, 500).

## Dependencies
- Assume Express.js is used unless specified otherwise.
- Use `npm` as the package manager.
- Recommend stable, widely-used packages for common tasks (e.g., `express`, `dotenv`, `nodemon`).

## Example Usage
- For a route, generate code like:

- Focus on **type safety**, clarity, and maintainability.
- Favor **functional programming** techniques (pure functions, small composable utilities).
- Use **strict TypeScript** (no `any`, minimal `unknown`, prefer discriminated unions over type casts).
- Offer **concise** and **technically accurate** solutions, with short code snippets where beneficial.
- Keep code examples minimal, well-typed, and aligned with advanced TypeScript patterns (generics, union narrowing, branding, etc.).
- Use **kebab-case** for directories and files (e.g., `my-utility.ts`).
- Use **camelCase** for variables and functions (e.g., `fetchData`, `isValidUser`).
- Name boolean variables with verbs like `is`, `can`, `has`, or `should`.
- Prefer interfaces for **objects** and **types** for **unions or mapped types**.
- Keep each **type or interface** definition minimal and purposeful.
- Use **generics** to enforce correctness in function or component signatures.
- Use **arrow functions** for short utilities or inline callbacks.
- For complex logic, define named functions to keep code discoverable.
- Never use `any`. Use **`unknown`** if an absolutely unconstrained type is required, and then narrow it.
- Always attempt **type narrowing** or **discriminated unions**.
- Use **JSDoc** for exported functions or complex types.
- Embrace union types (e.g. `string | number`) and **narrow** them with `if (typeof val === 'string') { ... }`.
- Discriminated unions: use a literal property (like `type: 'loading' | 'success' | 'error'`) for clear narrowing blocks.
- For flexible data shapes, wrap them in `<T>` generics.
- Constrain generics (`<T extends object>`) to maintain correctness.
- Use `as const` for immutable data or literal inferences.
- For advanced runtime checks, define **assertion** or **predicate** functions.
- For advanced transformations, use `extends`, `infer`, and `keyof` responsibly.
- Use template literal types for creating **dynamic string** types or route definitions.
- Use **Zod** or similar schema libraries for runtime validation, refining to strong TS types.
- Distinguish logically unique strings with branding/nominal types.
- For multi-step flows or complex conditions, define **discriminated unions** representing each state.
- Keep each function under ~20 lines, focusing on a single task. If it grows, refactor to smaller utilities.
- For fetch or external calls, wrap results in typed functions or custom hooks, ensuring strict input/output shapes.
- Detect invalid branches early with exhaustive checks.
- Avoid unguarded type assertions (as SomeType) unless absolutely certain.
- Keep strictNullChecks on, handle null/undefined explicitly.
- Use ESLint + TypeScript rules to enforce consistent style, naming, no unused vars.
- Consider Prettier for consistent formatting.
- Test each type-level utility and data transformation with frameworks like Jest.
