unfurrer

URL unfurling service that requires signed requests to function, running on Cloudflare Workers.

Setup

1. Install Wrangler 2 (yarn global add wrangler or npm i -g wrangler) or install it through this projects dependencies.
2. Generate a public Ed25519 key, exported under SPKI mode with PEM formatting. Should look like this:

-----BEGIN PUBLIC KEY-----
MCowBQYDK2VwAyEAzOWQ2fB4o1cNL8aBEz3EHdUQc9RlqVs+k4BMq/F5his=
-----END PUBLIC KEY-----

3. Set the inside (MCowBQYDK2VwAyEAzOWQ2fB4o1cNL8aBEz3EHdUQc9RlqVs+k4BMq/F5his=) as the PUBLIC_KEY secret (yarn wrangler secret put PUBLIC_KEY or npx wrangler secret put PUBLIC_KEY), responding to the prompt with the public key.
4. Edit wrangler.toml to have an up to date routes key.
5. Deploy with yarn deploy (or npm run deploy)!
