# Yumechi-no-kuni-proxy-worker

This is a misskey proxy worker for　ゆめちのくに (Yumechi-no-kuni) instance. Runs natively on both local and Cloudflare Workers environments!


Work in progress! Currently to do:

- [X] Content-Type sniffing
- [X] SVG rendering
   - [ ] Font rendering (likely will not run on Cloudflare Workers Free plan)
- [X] Preset image resizing
- [X] Opportunistic Redirection on large video files
- [X] RFC9110 compliant proxy loop detection with defensive programming against known vulnerable proxies
- [X] HTTPs only mode and X-Forwarded-Proto reflection
- [X] Cache-Control header
- [X] Rate-limiting on local deployment (untested)
- [X] Read config from Cloudflare
- [ ] Handle all possible panics reported by Clippy
- [ ] Sandboxing the image rendering
