Features

• 3s GIF of your face as it ages through time 🧓
• Store & retrieve photos from Cloudflare R2 using Workers

Deploy Your Own

You can deploy this template to Vercel with the button below:

Note that you'll need to:

• Set up a ReplicateHQ account to get the REPLICATE_API_TOKEN env var.
• Set up an Upstash account to get the Upstash Redis env vars.
• Create a Cloudflare R2 instance and set up a Cloudflare Worker to handle uploads & reads (instructions below).

Cloudflare R2 setup instructions

1. Go to Cloudflare and create an R2 bucket.
2. Create a Cloudflare Worker using the code snippet below.
3. Bind your worker to your R2 instance under Settings > R2 Bucket Bindings.
4. For extra security, set an AUTH_KEY_SECRET variable under Settings > Environment Variables (you can generate a random secret here).
5. Replace all instances of images.extrapolate.workers.dev in the codebase with your Cloudflare Worker endpoint.
