When university students use Express.js and Django for backend development, they should watch out for some common mistakes. Here are some important tips to keep in mind:
1. Don’t Ignore Documentation:
Both Express.js and Django have helpful guides. But sometimes students ignore these guides. Getting to know the official documentation can save a lot of time later when trying to fix problems.
2. Keep API Endpoints Simple:
It’s tempting to make APIs more complicated than needed. But it’s better to keep them straightforward. Use standard HTTP methods like GET, POST, PUT, and DELETE. This makes things clearer and easier to manage.
3. Handle Errors Properly:
Many beginners forget to handle errors well. Always try to catch mistakes and show helpful error messages. This not only makes the user experience better but also helps when figuring out what went wrong.
4. Manage Databases Wisely:
Students sometimes use raw SQL queries when they could use an Object-Relational Mapper (ORM). While using raw SQL gives more control, it can also cause security problems like SQL injection. Using the ORM in Django or building queries correctly in Express can improve security.
5. Don’t Overlook Middleware:
Middleware is important for processing requests. Ignoring it can cause slow performance or mistakes, like not correctly checking if users are logged in.
6. Pay Attention to Security:
Forget about adding proper authentication and authorization, and your application might be at risk. It’s crucial to follow best practices to secure REST APIs, like using tokens or properly managing sessions.
By avoiding these common pitfalls, students can build better skills in backend development. This will lead to making stronger and safer web applications.
