The core team is the reason everything flows smoothly like butter. All the biological systems and nerves are the nodes, and the spine is their server, which in turn guides the organs simultaneously.Īnalogy 2 – Another analogy to understand the importance of the backend is how the event organizers are the backbone of an event. PostgreSQL is a powerful, open-source relational database management system that supports advanced SQL features, transactions, and concurrency control.“What is Expressjs?” “Is Express.js a good choice for web app backend?” - Well, allow us to take you through a trail before explaining Express JS basics…įurthermore, taking two analogies to understand the importance of a backend framework – Express js (in this case).Īnalogy 1 – We are not unaware of the importance of the spinal cord in the human body. It uses an event-driven, non-blocking I/O model, which makes it lightweight and efficient.Įxpress.js is a web application framework for Node.js that provides a set of features for building web applications and APIs, such as routing, middleware, and error handling. Node.js is an open-source, cross-platform, runtime environment that allows developers to use JavaScript to build server-side applications. RESTful APIs typically use HTTP methods such as GET, POST, PUT, and DELETE to interact with resources, and they use URIs (Uniform Resource Identifiers) to identify resources. Uniform interface: The API should have a consistent interface that is easy to understand and use.

Layered system: A client may not be aware of all the layers in the system, which allows for better encapsulation and modularity. Statelessness: The server does not store any client context, which allows for better scalability and reliability.Ĭacheability: Responses from the server can be cached to improve performance. It is designed to be stateless and follows a set of architectural principles, including:Ĭlient-server architecture: The client and server are separated and communicate through a uniform interface. A RESTful API (Representational State Transfer) is a type of API that uses HTTP requests to access and manipulate data.
