Cannot name file

[maka-io]

I don't see a way to name the files as they are uploaded, they just get a name of "upload_" is there a way to change that, or append an extension?

The original filenames are available, you can rename the uploads to whatever you like when moving them to permanent storage.

Ok, so that's something I'd have to do manually? There isn't a setting?

Yes, it is something you need to do manually.

You might find this earlier discussion interesting, although these days I do things a bit diffirently and permanently store files in MongoDB GridFS.

In the next several weeks, once our platform launches and I get back from a trip to San Fransisco for GraphQL Summit, I hope to work on providing file streams instead of metadata to resolvers (#13).

Hope that helps 🙂

[maka-io]

That does, and thank you!

Yeah, you'd have to rename it after upload manually. I ended up not storing stuff in my database, just using Amazon S3 with s3fs and deleting the temp upload folder every now and then:

import S3FS from 's3fs'; // Amazon web services file system
import config from '../../config';

const amazonFileSystem = new S3FS('yourBucket',	{
	region: config.amazonS3.region,
	accessKeyId: config.amazonS3.id,
	secretAccessKey: config.amazonS3.secret,
});

export default amazonFileSystem;

import fs from 'fs';
import readChunk from 'read-chunk';
import fileType from 'file-type';
import uuid from 'uuid';

async function uploadToAmazon(path, name = uuid.v4()) {
	try {
		// Get File Type
		// Only needs first 4100 bytes
		const fileTypeBuffer = await readChunk(path, 0, 4100);
		const type = fileType(fileTypeBuffer);

		if (!type) {
			throw new Error('No file type.');
		}

		// RegExp only allow image mime type
		if (!/^image/.test(type.mime)) {
			throw new Error('Wrong file type.');
		}

		// Generate thumbnails and compress

		const newFileName = `${name}.${type.ext}`;
		const stream = fs.createReadStream(path);

		// Upload file to Amazon S3
		amazonFileSystem.writeFile(
			newFileName,
			stream,
			{ ContentType: type.mime },
		);

		return `https://s3.${config.amazonS3.region}.amazonaws.com/yourBucket/${newFileName}`;
	} catch (e) {
		throw new Error(e);
	}
}
