A web framework is a code library that makes web development faster and easier by providing common patterns for building reliable, scalable and maintainable web applications. After the early 2000s, professional web development projects always use an existing web framework except in very unusual situations.
Why are web frameworks useful?
Web frameworks encapsulate what developers have learned over the past twenty years while programming sites and applications for the web. Frameworks make it easier to reuse code for common HTTP operations and to structure projects so other developers with knowledge of the framework can quickly build and maintain the application.
Functionalities of Web Framework
Frameworks provide functionality in their code or through extensions to perform common operations required to run web applications. These common operations include:
1. Database Manipulation
Web frameworks allow for the manipulation of databases. For example, in order to store data in a SQL database, you must first decide how to structure the data by writing a pre-defined schema (The way in which your database will read and store the incoming data). Web frameworks provide the ability to perform reads, writes and schema structuring.
2. Security and Scalability
Frameworks provide basic security measures to help keep your data protected. They also contain the ability to quickly scale when necessary so you can run applications and websites on a global basis with no setbacks in performance.
3. URL Routing
