How to access the GET parameters after “?” in Express

To access the GET parameters after "?" in Express, you can use the req.query object. This object contains a property for each query parameter in the route. By accessing the req.query object, you can retrieve the values of the parameters.

Here's a step-by-step explanation:

1. When a client makes a GET request with parameters in the URL, Express automatically parses the query string and populates the req.query object with the key-value pairs.

2. To access the values of the parameters, you can use the req.query object followed by the name of the parameter. For example, if the URL is /users?id=123, you can access the value of id using req.query.id.

3. If there are multiple parameters in the URL, you can access each parameter's value by using the respective property of the req.query object.

By following these steps, you can effectively access the GET parameters after "?" in Express and use the values as needed in your application.
