This is awesome! I thought I'd see if I could make a couple little improvements, but no pressure to accept any of them.

1. I used Deno.env.get instead of process.env because we can skip an import
2. I added a README.md file with a bit of extra context
3. I handle GET requests by linking to the val itself. This isn't terribly beautiful code. If you have any suggestions or feedback, I'm all ears.

If you only want some of these changes, feel free to copy and paste the ones you want into your code vs merging them all.
