- Input Validation: Always validate data before storing it. If you don't validate inappropriate data before storing , it corrupts all your valid data as well.
- Avoid Hardcoding Values: Hardcoding values makes the code static and difficult to maintain. Instead, use configuration files or databases to store these values, making them easier to change and manage.
- Minimize Tight Coupling: Avoid direct instantiation of classes or dependencies on specific implementations. Tight coupling makes it difficult to modify one part of the application without affecting others.
- Prioritize Unit Testing: Even if you're busy, prioritizing unit testing is crucial. Although developers may feel they don't have time, unit tests prevent future bugs and save time in the long run.
- Handle Exceptions Properly: If your APIs return detailed stack traces when errors occur, you're potentially exposing your system to attackers. Instead, log exceptions and return a generic error message.
- Write Readable Code: You often spend more time reading code than writing it. As the saying goes, "Any fool can write code that a computer can understand. Good programmers write code that humans can understand."
- Design Your Database Carefully: Poor database design can hinder application performance and scalability. Invest time in creating an optimized and efficient database structure.
- Don't Ignore Security: Always validate user input and follow secure coding practices to protect your application from threats and attacks.
- Implement Logging and Monitoring: An application without logging and monitoring is like an airplane without an instrument panel. You may release and launch your app, but you won’t be aware of its status and performance without comprehensive monitoring.
- Reinventing the Wheel:?Invest time into creating a component already developed , tested and widely used within the community is a deadly mistake , you assume make break down in future so reinvent the logic is mandatory.
