fukusu is a middleman between the uploadthing package and your own storage bucket. this means you basically get the freedom to use any provider but with the incredible DX of uploadthing.

• Cloudflare R2
• Backblaze B2
• Generic S3 provider

• uploads
• multiple apps
• authed requests (currently assumes that everything is authenticated)

simple! firstly, deploy your fukusu server. you can do this easily with the Deploy with Cloudflare button below:

once your fukusu server is online, you'll need to get your API key. you can get this by going to:

https://<your-fukusu-server-url>/__fukusu/genkey?secret=<your_secret_key>

You can now add environment variables to your .env file to configure Uploadthing to work with your fukusu server:

UPLOADTHING_TOKEN="<your-api-key-here>"
UPLOADTHING_INGEST_URL="https://<your-fukusu-server-url>"
UPLOADTHING_API_URL="http://<your-fukusu-server-url>"

For some frameworks (cough cough svelte cough cough), you'll need to modify your createRouteHandler to include a configuration object that points UploadThing to your server.

// this is an example of how you'd use it in sveltekit:
// /src/routes/api/uploadthing/+server.ts
//
import { env } from '$env/dynamic/private';
import { ourFileRouter } from '$lib/server/uploadthing';

import { createRouteHandler } from 'uploadthing/server';
const handlers = createRouteHandler({
	router: ourFileRouter,
	config: {
		token: env.UPLOADTHING_TOKEN,
		ingestUrl: env.UPLOADTHING_INGEST_URL,
	}
});

export { handlers as GET, handlers as POST };

and now your uploads will work! for any UTApi instances you also need to add the configuration to them. you may do the following:

const utApi = new UTApi({
  apiUrl: env.UPLOADTHING_API_URL", // you can also use env.UPLOADTHING_INGEST_URL
  ingestUrl: env.UPLOADTHING_INGEST_URL,
  token: env.UPLOADTHING_TOKEN
});

and voila! it's all done.
