Working With Express - Route and Query Parameters
In this lab, you will learn how to create routes that will accept route and query parameters inside an Express application. The route parameter, which is sometimes referred to as the path parameter, is a named segment of the route and is used to access a specific resource of data. A query parameter, also known as a query string, is a set of parameters attached to the URL. The query parameter is often used to request data based on given criteria. The lab scenario is a clothing company that is creating a custom CRM for its customers. You are building the routes for this express application. The data structure for this application is located in the
customerdata.js file that is inside the data folder. You can use this as a reference to understand how the routes are created to access specific data resources. If this is your first time working on the new express lab, make sure to watch the Introduction to Express Labs Video.
Upon completion of this beginner, you will be able to:
- Understand how route parameters work in Express
- Understand how query parameters work in Express
- Be able to implement a GET route with a route parameter as part of the path
- Be able to implement a GET route to capture a query parameter
