Setup

0. I'm using asdf to manage Node and PNPM, you can install it or install PNPM yourself
1. Clone the repository
2. pnpm install
3. In Backblaze, create a new Application Key, with only access to single bucket
4. Copy config/private.example.ts to config/private.ts, copy the keys into it
5. You need to also put at least a username and password pair
6. In Cloudflare Dashboard, create a new KV Namespace
7. Copy wrangler.example.toml to wrangler.toml, copy the KV id there
8. pnpm run deploy
9. Add custom domain to the worker and disable the workers.dev route (to enable response caching)
