Understanding the Problem

As seen in a typical use case, you have set up a catch all API route (located at /api/matches/[...matchslug].js) that fetches match data based on a slug. The goal is to allow users to fetch data for multiple matches in a single API call, like this:

In this setup:

Each slug corresponds to a specific match.

The goal is to return combined data for multiple matches from a single request to your API.

Why Your Current Approach Is Not Working

The issue arises in how you are trying to process the slugs. Your matchslug variable is not a single value but an array consisting of multiple slugs. This means that simply passing this array to your fetch calls will not yield the expected results.

Current Code Structure

Here’s a brief look at your current API route:

By trying to use a single slug for fetching data, you're only able to retrieve results for a single match and not for multiple.

To effectively fetch data for each slug, you'll need to adjust your approach as follows:

Map Over the Slugs: You can loop through each slug in the matchslug array to fetch data for each match.

Revised Code Example

Here’s how you can refactor your handler function to accommodate fetching multiple resources:

Breaking Down the Code

Mapping the Slugs: The map() method creates an array of promises that fetch data for each slug.

Fetching Data: Each fetch() call retrieves data based on the respective slug.

Sending a Response: The combined data is then sent back as a JSON response to the client.

Conclusion

Just remember, whenever you’re working with dynamic routes that expect multiple parameters, always consider how to handle those parameters effectively to achieve the desired functionality. Happy coding!
