# Code Style Guidelines | ||
|
||
## 1. Naming Conventions | ||
- Use clear, descriptive names for variables, functions, and classes. | ||
- Follow camelCase for variables and functions, PascalCase for classes. | ||
- Use UPPER_CASE for constants. | ||
- Prefix private members with an underscore (e.g., _privateVariable). | ||
|
||
## 2. Code Structure | ||
- Keep functions short and focused on a single task. | ||
- Limit line length to 80-100 characters for improved readability. | ||
- Use consistent indentation (preferably 2 or 4 spaces). | ||
- Group related code blocks together. | ||
- Follow the DRY (Don't Repeat Yourself) principle to avoid code duplication. | ||
|
||
## 3. Documentation | ||
- Include clear, concise comments for complex logic or algorithms. | ||
- Use docstrings for functions, classes, and modules, describing purpose, parameters, and return values. | ||
- Keep documentation up-to-date with code changes. | ||
- Use TODO comments for planned improvements or known issues. | ||
|
||
## 4. Error Handling | ||
- Use try-catch blocks for error-prone operations. | ||
- Provide informative error messages. | ||
- Log errors with appropriate severity levels. | ||
- Handle exceptions at the appropriate level of abstraction. | ||
|
||
## 5. Performance | ||
- Optimize critical paths and frequently executed code. | ||
- Use appropriate data structures for efficient operations. | ||
- Minimize database calls and optimize queries. | ||
- Implement caching strategies where applicable. | ||
|
||
## 6. Security | ||
- Validate and sanitize all user inputs. | ||
- Use parameterized queries to prevent SQL injection. | ||
- Implement proper authentication and authorization mechanisms. | ||
- Follow the principle of least privilege for access control. | ||
- Keep sensitive data encrypted at rest and in transit. | ||
|
||
## 7. Testing | ||
- Write unit tests for individual components and functions. | ||
- Implement integration tests for system interactions. | ||
- Maintain a high test coverage for critical code paths. | ||
- Use mock objects and stubs for testing dependencies. | ||
|
||
## 8. Version Control | ||
- Write clear, descriptive commit messages. | ||
- Use feature branches for new developments. | ||
- Perform code reviews before merging into the main branch. | ||
- Keep commits small and focused on a single change. | ||
|
||
## 9. Code Reusability | ||
- Create modular and reusable components. | ||
- Use design patterns appropriately to solve common problems. | ||
- Implement interfaces and abstract classes for flexibility. | ||
|
||
## 10. Maintainability | ||
- Refactor code regularly to improve readability and structure. | ||
- Remove dead code and unused variables. | ||
- Keep dependencies up-to-date and manage them effectively. | ||
- Document architectural decisions and system design. |
