Best Practices

This document outlines the standards and recommendations to ensure high-quality, maintainable, and scalable code across our projects.

Code Style​

  • Linting and Formatting: Use our configured linter (e.g., ESLint) and formatter (e.g., Prettier) to maintain consistent style.
  • Naming Conventions: Follow clear and descriptive naming for variables, functions, classes, and files.
  • Commenting: Write concise comments where necessary to explain complex logic, but avoid excessive commenting.

Testing​

  • Unit Tests: Cover critical components and logic with unit tests (e.g., using Jest, Mocha, or similar frameworks).
  • Integration Tests: Validate the interaction between modules or services.
  • Continuous Integration (CI): Ensure all tests pass before merging any pull requests.

Security​

  • Dependency Management: Regularly update dependencies and address vulnerabilities.
  • Secrets Handling: Never commit secrets (API keys, tokens) to the repository. Use environment variables or a secure vault.
  • Validation and Sanitization: Always validate and sanitize user input to prevent common attacks (SQL injection, XSS, etc.).

Performance​

  • Profiling and Optimization: Identify bottlenecks using profiling tools.
  • Caching: Implement caching strategies where applicable to reduce redundant operations.
  • Scalability: Design features with future growth in mind (e.g., load balancing, microservices).

Documentation​

  • Clarity: Write clear and concise docs that are easy to follow.
  • Updates: Keep the documentation up to date with any changes in the code or architecture.
  • Consistency: Follow the same structure and style for all documentation files.
