General Guidelines

• Use version control (Git) for all projects.
• Write clean, readable, and well-documented code.
• Follow the DRY (Don't Repeat Yourself) principle.
• Implement proper error handling and logging.
• Regularly update dependencies and address security vulnerabilities.
• Use linters and formatters (e.g., ESLint, Prettier) to maintain code quality and consistency.

Naming Conventions

• Use camelCase for variable and function names (e.g., getUserData, isValid).
• Use PascalCase for class and component names (e.g., UserProfile, Button).
• Use UPPER_SNAKE_CASE for constants (e.g., MAX_RETRY_COUNT, API_BASE_URL).
• Use kebab-case for file names (e.g., user-profile.tsx, api-utils.ts).
• Prefix interface names with "I" (e.g., IUserData).
• Use descriptive and meaningful names for all identifiers.

Environment Variables

• Store sensitive information (API keys, database credentials) in environment variables.
• Use a .env file for local development and ensure it's included in .gitignore.
• Reference environment variables using process.env.VARIABLE_NAME in Node.js and Next.js.
• For React Native, use a package like react-native-dotenv to manage environment variables.
• Never hardcode sensitive values directly in the source code.

Next.js Best Practices

• Use Static Generation (SSG) whenever possible for better performance.
• Implement dynamic imports and lazy loading for better code splitting.
• Utilize Next.js Image component for optimized image loading.
• Implement proper SEO practices using Next.js Head component.
• Use getServerSideProps for server-side rendering when necessary.
• Implement proper error handling and custom error pages.

Node.js Best Practices

• Use async/await for asynchronous operations instead of callbacks.
• Implement proper error handling using try/catch blocks.
• Use middleware for common functionalities (e.g., authentication, logging).
• Implement input validation and sanitization to prevent security vulnerabilities.
• Use a process manager like PM2 for production deployments.
• Implement proper logging using a library like Winston or Pino.

React Native (with Expo) Best Practices

• Use functional components and hooks instead of class components.
• Implement proper navigation using React Navigation.
• Use Expo SDK features and APIs when available.
• Optimize performance by minimizing re-renders and using memoization.
• Implement proper error boundaries to catch and handle errors gracefully.
• Use responsive design practices to ensure compatibility across different device sizes.

TypeScript Best Practices

• Define proper types and interfaces for all data structures.
• Use type inference when possible to reduce verbosity.
• Utilize union types and intersection types for more precise type definitions.
• Use unknown instead of any when the type is truly unknown.
• Leverage TypeScript's strict mode for enhanced type checking.
• Use generics to create reusable components and functions.

Code Review Process

• All code changes must go through a pull request process.
• At least one team member must review and approve the changes before merging.
• Use a consistent PR template to ensure all necessary information is provided.
• Reviewers should check for code quality, adherence to guidelines, and potential bugs.
• Address all comments and suggestions before merging the PR.
• Squash commits before merging to maintain a clean Git history.
