SyntaxError: Named export 'fromBuffer' not found.

Hey there,

first off all BIG thanks for this project. I made a video streaming backend and created the requests manually, but switched now to your client as it makes my life much easier.

However, I'm having a problem:

I'm using NextJS (13.1.6) API routes and get the following error:

My code looks like this:

export default withUserGuard(async function handler(req, res) {
    if (req.method !== 'GET') {
        res.setHeader("Allow", ["GET"]);
        return res.status(405).json({ error: `Method ${req.method} Not Allowed` });
    }
    try {
        const mostRecent = await getMostRecentVideos();
        return res.status(200).json({ mostRecent });
    } catch (e) {
        return res.status(500).end();
    }
});

const getMostRecentVideos = async () => {
    const videos = await stream.listVideos({
        page: 1,
        itemsPerPage: 10,
        orderBy: 'date'
    })

    return videos.items.map((video) => ({
        viewTime: prettyPrintSeconds(video.length),
        collection: collectionIdToGenre.get(video.collectionId),
        ...video,
    }));
};

Do you have an idea how to solve that or is there a way to allow CommonJS modules properly?
Thanks and all the best!

I checked your code and tried the following:

so there is an issue somewhere. If you have an idea -> great, if not I'd think about it and contribute when I found the issue :)

try fileType.fromBuffer() this would theoretically solve the issue. I will create a pull request regarding this.

@Abdulazeez-98 yes the screenshot above is of the npm package. I modified it and it worked so yeah not sure why it bundles it like that but it does not work. Thanks for the PR!

You're welcome 👍
The library "file-type" doesn't export individual objects because it only supports CommonJS (or at least that's my understanding). So we need to import the whole thing and then call the function fromBuffer().
This is a limitation in the "file-type" library for not supporting ESM imports. There's a new version of this library but it only supports ESM and not CommonJS. Most NPM libraries support both module systems.

Ah yes the usual discrepancies between cjs and esm, personally I promote the use of esm for everything but I understand why you would need a cjs bundle. Tad annoying that libraries like this don't support both 😕

Thanks @Abdulazeez-98 for the PR, I'll test it and get that merged if everything looks good
