cmcgrabby-hue 52e2777821 feat(dashboard): support serving under URL prefix via X-Forwarded-Prefix
The Hermes dashboard previously assumed it was served at the root of its
host (e.g. https://kanban.tilos.com/). When mounted behind a path-prefix
reverse proxy (e.g. https://mission-control.tilos.com/hermes/), the SPA
404'd because:

- index.html shipped absolute /assets/index-*.js URLs
- React Router had no basename
- The plugin loader hit /dashboard-plugins/<name>/... at the root host
- CSS in the bundle had absolute url(/fonts/...) references

This patch makes the dashboard prefix-aware at runtime, no rebuild
required. The proxy injects 'X-Forwarded-Prefix: /hermes' on every
request and the Python server:

- Rewrites href/src in served index.html to '${prefix}/assets/...'
- Injects 'window.__HERMES_BASE_PATH__="${prefix}"' for the SPA to read
- Rewrites url() refs in CSS at serve time

The SPA reads window.__HERMES_BASE_PATH__ once at boot and:

- Prefixes all /api/... fetches via api.ts
- Prefixes all /dashboard-plugins/... script/css URLs in usePlugins
- Sets <BrowserRouter basename={...}> so client-side routing works

When no X-Forwarded-Prefix header is present, behavior is unchanged
(empty prefix => serves at root, kanban.tilos.com keeps working).

Hermes Agent — Web UI

Browser-based dashboard for managing Hermes Agent configuration, API keys, and monitoring active sessions.

Stack

  • Vite + React 19 + TypeScript
  • Tailwind CSS v4 with custom dark theme
  • shadcn/ui-style components (hand-rolled, no CLI dependency)

Development

# Start the backend API server
cd ../
python -m hermes_cli.main web --no-open

# In another terminal, start the Vite dev server (with HMR + API proxy)
cd web/
npm run dev

The Vite dev server proxies /api requests to http://127.0.0.1:9119 (the FastAPI backend).

Build

npm run build

This outputs to ../hermes_cli/web_dist/, which the FastAPI server serves as a static SPA. The built assets are included in the Python package via pyproject.toml package-data.
