Reverse proxy — everything on HTTPS / 443¶

By default the pieces of Danbyte run on separate dev ports:

Service	Port	What
SPA (Vite dev server)	`3000`	The React app
Django + DRF	`8000`	API (`/api/`) + admin
Zensical docs	`8001`	This documentation site

The optional nginx reverse proxy puts all of them behind one HTTPS origin so users hit a single URL and the docs link in the sidebar resolves to a clean same-origin /docs/:

https://<host>/          → SPA
https://<host>/api/      → Django API
https://<host>/admin/    → Django admin
https://<host>/docs/     → these docs

Install¶

One command (needs sudo — it installs nginx, generates a self-signed cert, writes the site config, and reloads nginx):

make proxy-install

Override the hostname/IP baked into the cert + server_name:

make proxy-install PROXY_HOST=danbyte.lan

Then make sure the upstreams are running:

make backend-up docs-up      # Django :8000 + Zensical :8001
make frontend-dev            # Vite :3000 (separate terminal)

Visit https://<host>/. The self-signed cert triggers a one-time browser warning on the LAN — accept it. For a browser-trusted local cert, install mkcert and point CERT/KEY at its output, or drop a real cert in /etc/ssl/danbyte/.

How it's wired¶

Source of truth is the template deploy/nginx/danbyte.conf.template; the @@SERVER_NAME@@ / @@CERT@@ / @@KEY@@ placeholders are substituted into /etc/nginx/sites-available/danbyte.conf at install time. Edit the template, not the installed copy, then make proxy-reload.
/docs/ proxies the Zensical server with the prefix stripped; the built docs use relative links, so they sit happily under the subpath.
/ proxies the Vite dev server with websocket upgrade so HMR keeps working. For a production deployment, point that location / at your built SPA / Django static host instead of :3000.

Commands¶

Command	Effect
`make proxy-install`	Install nginx (if missing) + cert + config, enable & reload.
`make proxy-reload`	Re-render the template and reload nginx (after edits).
`make proxy-uninstall`	Remove the danbyte site and reload nginx.
`make proxy-cert`	(Re)generate the self-signed cert into `deploy/nginx/certs/`.

Notes¶

HMR through the proxy: Vite's hot-reload websocket assumes the dev port. If live-reload misbehaves behind 443, develop against http://<host>:3000 directly — the proxy is for unified access, not required for development.
The proxy is opt-in; nothing else depends on it. Without it, the docs link falls back to http://<host>:8001/.
