Code Review Best Practices

Have you ever found yourself approving a pull request (PR) with a cursory glance, just asking if it was well-tested before giving it the green light? It's a common scenario, especially when deadlines loom large. However, in our quest for speed, we risk compromising code quality. Let's explore some key checkpoints to consider during your next code review to ensure the integrity and robustness of your codebase.



1. Product Requirements:

Before diving into the code changes, take a moment to review the scope of the ticket. Understanding the context and objectives of the task ensures that the implemented changes align with the project's goals.


2. Backward Compatibility:

Analyze the impact of the proposed changes on existing features. Ensure that the new code integrates seamlessly with the current codebase without causing any regressions.


3. Future Feature Compatibility:

Consider the future scalability of the code. Will it accommodate future enhancements and features without requiring significant refactoring? Aim for code that is adaptable and future-proof.


4. Code Reusability:

Encourage code reuse wherever possible. Identify opportunities to refactor common functions or modules to promote maintainability and reduce redundancy.


5. Security Vulnerabilities:

Stay vigilant about security vulnerabilities. Keep an eye on package versions and API endpoints to ensure that your code remains secure and resilient against potential threats.


6. Correctness and Optimization:

Verify the logic of the code and optimize where necessary. Strive for code that not only works as intended but also performs efficiently and effectively.


7. Code Readability and Design:

Lastly, ensure that the code is readable and follows good low-level design practices. Clarity and consistency in coding style contribute to the maintainability and comprehensibility of the codebase.


Code reviews are more than just a checklist of tasks to be completed. They're an opportunity to foster collaboration, share knowledge, and uphold standards of excellence. So, the next time you're reviewing code, take a moment to appreciate the effort and craftsmanship behind it. Who knows, you might just make someone's day! 😊
