✅ Best Practices

Development Best Practices & Guidelines

To ensure clean, maintainable, and efficient code, follow these best practices:

1. Follow a Consistent Code Style

   • Stick to a readable and consistent format.
   • Use proper indentation and spacing.

2. Write Clear and Descriptive Code

   • Use meaningful variable and function names.
   • Keep functions small and focused on a single task.

3. Document Your Code

   • Add docstrings for all functions explaining their purpose and parameters.

4. Ensure Error Handling

   • Always handle possible errors and exceptions.
   • Avoid exposing raw error messages to users.

5. Use Proper Status Codes in APIs

   • Return the correct HTTP status codes for API responses (e.g., 200 for success, 400 for bad requests, 500 for server errors).

6. Write Unit Tests

   • Include unit tests for new features to prevent future bugs.

7. Prioritize Reusability

   • Write modular, reusable code to avoid duplication.
   • Use helper functions or utility files where needed.

🔐 Security Best Practices

To protect our systems and data, always follow these security guidelines:

1. Never Commit Sensitive Data

   • Avoid committing passwords, API keys, or private tokens to the repository.
   • Use .gitignore to exclude sensitive files when necessary.

2. Use Environment Variables for Credentials

   • Store sensitive information like database URLs, API keys, and authentication tokens in environment variables.
   • Never hardcode credentials in the codebase.

3. Follow Secure Coding Practices

   • Validate and sanitize all user inputs to prevent SQL injection and XSS attacks.
   • Use parameterized queries when working with databases.

4. Ensure Regular Security Audits

   • Perform security reviews and compliance checks to identify vulnerabilities.
   • Keep dependencies and frameworks up to date to patch security flaws.

5. Manage Access and Permissions

   • Follow the principle of least privilege (only give access when necessary).
   • Use role-based access control (RBAC) where applicable.

Following these best practices ensures high-quality code, better maintainability, and robust security in Frappe projects. 🚀
