Understanding Path Parameters

Path parameters are segments of a URL that are defined in the path of an endpoint and are used to pass data to the server. They are commonly used for resource identification and can be essential for routing purposes.

For example, in the URL http://example.com/users/123, 123 is a path parameter that might represent a user ID.

Path parameters are an essential part of RESTful APIs, allowing the server to capture values from the URL and use them in request handling. This capability is crucial for creating dynamic and flexible endpoints. In Node.js, especially when using frameworks like Express.js, handling path parameters is straightforward and efficient. In this article, we’ll explore how to read path parameters in Node.js and use them in your applications.
