What Are Backend Frameworks?

Backend frameworks are tools or platforms that help developers build the server side of web applications. They provide ready‑made structures, reusable code, and common features like routing, databases, and security. This saves time, reduces errors, and allows developers to focus on building features instead of writing everything from scratch.

To understand backend frameworks better, it helps to see how they differ from frontend frameworks. While the frontend is what the user interacts with, the backend makes sure everything runs smoothly behind the scenes.

Role of Backend Frameworks in Web Application Development

• A backend framework provides a strong base for handling server logic and communication with databases.
• It simplifies tasks such as user authentication, data storage, and API creation.
