An example of an AI chatbot conversation about Express route parameter types.
What are the different types of route parameters in Express?
In Express, route parameters are named URL segments that can capture values. There are two main types: path parameters and query parameters.
Can you give me an example of a path parameter?
Sure! A path parameter is defined in the route path, like this: /users/:userId. Here, :userId is a path parameter that captures the user ID from the URL.
What about query parameters?
Query parameters are appended to the URL after a question mark. For example, in /search?query=express, query is a query parameter.
How do I access these parameters in my Express app?
You can access path parameters using req.params and query parameters using req.query in your route handler.
