This issue can be frustrating, especially when you believe your code is sound. Let's dive into why this happens and how you can resolve it effectively. Understanding the Problem The root of the issue lies in the route handling for POST requests in your search functionality. In Express, every HTTP request needs to be explicitly defined. In your current code, you have only defined a GET request for the /search route, which means the application is unable to handle requests made with the POST method. Here's how your search router is currently set up: [[See Video to Reveal this Text or Code Snippet]] Key Points: You defined a GET request for searching. The request body is generally not populated for GET requests. This is why you are experiencing issues when trying to access req.body.search. The Solution: Adding a Proper POST Request Handler To properly handle the POST request for your /search route, you need to introduce a new method in your router. Here’s how you can do that: Step 1: Modify Your searchRouter.js Add a POST request handler to your searchRouter.js file as shown below: [[See Video to Reveal this Text or Code Snippet]] Step 2: Consider Using GET Instead Although the above solution will solve the error you are facing, it is important to note that using a GET request for search functionality may be more logical and conventional. Users typically submit search queries via GET requests because this allows them to bookmark or share the search link easily. If you decide to change your route to handle a GET request instead, simply replace the POST with GET in your code. Additionally, ensure that any form used to submit the search query has the method set to GET: [[See Video to Reveal this Text or Code Snippet]] Conclusion By adding the appropriate POST request handler or considering a GET request for your search functionality, you can resolve the Cannot POST /search error in your Express application. This adjustment will not only fix the error but also enhance the usability of your application. Remember, understanding how request methods function in Express will greatly improve your development workflow.
