The Problem: Error with fetch in Search Queries

A developer was facing an issue when trying to implement a search component in their project. The goal was to filter products from the database based on a name input, but they encountered an error when using the fetch API:

This error occurred because the developer was trying to send a request body with a GET request, which is not supported. Additionally, they wanted to explore using MongoDB Atlas Search to enhance their search functionality.

Solution: Correcting the Fetch Request and Utilizing Query Parameters

Step 1: Adjusting the Fetch Request

Instead of using a request body in the GET method, you should send your search terms as query parameters in the URL. Here's how to do that effectively:

In this updated function, we’re using URLSearchParams to encode the search term properly, making it a part of the query string.

Step 2: Handling the Backend Request

In this sample, we're using a regular expression to perform a case-insensitive search for the product names.

Step 3: Displaying the Results on the Frontend

After the fetch call in handleSearch, you will need to handle the response. If the request is successful, update your component’s state to reflect the filtered products:

Conclusion

If you're looking to implement more advanced features, consider exploring MongoDB Atlas Search to further refine your search capabilities.

Implement this approach in your projects, and happy coding!
