# Halfstreet

A gothic text adventure. Second person, present tense, sparse — never explains.

Style anchors: Le Fanu's *Carmilla*, Shirley Jackson's *The Haunting of Hill House*, M.R. James's ghost stories.

Played at [halfstreet.io](https://halfstreet.io).

## Stack

- [Astro](https://astro.build) static site
- TypeScript engine — pure (no DOM, `Date`, `Math.random`, or console)
- World content authored in markdown (rooms, items, encounters, endings) under `src/world/`
- [Vitest](https://vitest.dev) for tests
- Optional client error reporting via [GlitchTip](https://glitchtip.com) using `PUBLIC_GLITCHTIP_DSN`

## Development

```sh
npm install
npm test          # engine + world tests
npm run dev       # local dev server
npm run build     # type-check + production build
```

To enable GlitchTip in the browser, set `PUBLIC_GLITCHTIP_DSN` in your environment before running or building the site.
If you want deploy-aware grouping and readable stack traces, also set `PUBLIC_GLITCHTIP_RELEASE` at build time and upload the generated source maps for that same release.

## Layout

- `src/engine/` — parser, dispatcher, encounter logic
- `src/ui/` — terminal renderer, theme, chips
- `src/world/` — markdown content (rooms, items, encounters, endings)
- `src/pages/index.astro` — entry page
