  # Deploy and Host demo-host on Railway
  
  demo-host is a tiny, dependency-free static host for the demos job-signal
  generates. Each deploy is your **own** private copy: demos you build are uploaded
  to it and served at clean public links like `/apple`, `/stripe`, or `/notion` —
  many demos living on a single site.
  
  ## About Hosting demo-host

  Hosting demo-host gives you a personal, always-on home for shareable demo pages.
  The service exposes a tiny API — `PUT /upload/` (token-protected) to store a
  demo and `GET /` to serve it publicly — backed by a persistent volume so
  your demos survive restarts and redeploys. Railway auto-provisions the volume and
  a unique upload token on deploy, so there's nothing to wire up by hand: deploy,
  generate a domain, and connect it in job-signal Settings.

  ## Why Deploy demo-host on Railway

  Railway is the natural home for demo-host because a single click provisions
  everything it needs — the service, a persistent `/data` volume, and a freshly
  generated upload secret — with zero CLI and zero manual config. You stay in full
  control: it's deployed to *your* account, on *your* domain, with *your* token.
  Built-in healthchecks and on-failure restarts keep the host available, and
  Railway's generated domain gives you a public link to drop straight into outreach.

  ## Common Use Cases 

  - Hosting interactive sales/outreach demos generated by job-signal at per-company links.
  - Sharing a self-contained static demo with a prospect via a clean public URL.
  - Keeping a personal, private library of many demos served from one lightweight site.

  ## Dependencies for demo-host Hosting
  
  - A Railway account (free to start).
  - A persistent volume mounted at `/data` for storing uploaded demos.
  - Python 3 (provided automatically by Railway's Nixpacks builder) — the app uses
    the standard library only, so there are no third-party packages to install.

  ### Deployment Dependencies   

  - [Railway](https://railway.com) — hosting platform.
  - [job-signal](https://github.com/envisiondash/job-signal) — generates the demos
    and uploads them to this host.
  - `DEMO_HOST_TOKEN` (`${{ secret(48) }}`) and `DEMO_HOST_DATA_DIR` (`/data`)
    variables, plus the volume at `/data`.
