Frameworks Toupas recognises

Detected from the app's files; every default can be changed in toupas.json.

Preset	Detected by	Kind	Defaults
`vite`	`vite` dependency / `vite.config.*`	static	`npm run build` → `dist`, single-page app
`create-react-app`	`react-scripts`	static	`npm run build` → `build`
`astro`	`astro` (static output)	static	`npm run build` → `dist`
`sveltekit-static`	`@sveltejs/adapter-static`	static	`npm run build` → `build`
`nextjs-export`	`output: "export"` in the Next config	static	`npm run build` → `out`
`nextjs`	`next`, without `output: "export"`	server	Needs `output: "standalone"` in the Next config; starts `node server.js`
`express` / `node`	`express`, another server library, or a `start` script	server	`npm ci`, `npm run build` if there is one; starts the `start` script, or `node` with `main`, `server.js`, `index.js` or `app.js`
`fastapi`	`fastapi`	server	Starts `uvicorn <module>:<app> --host 0.0.0.0 --port $PORT`. Needs `uvicorn` (or `fastapi[standard]`) in the dependencies
`flask`	`flask`	server	Starts `gunicorn -b 0.0.0.0:$PORT <module>:<app>`. Needs `gunicorn` in the dependencies
`python`	`requirements.txt`, `pyproject.toml` or `uv.lock`	server	Set `start` in `toupas.json`
`static`	an `index.html` and nothing else	static	The folder as it is

Package managers: package-lock.json → npm ci, pnpm-lock.yaml → pnpm, yarn.lock → yarn; uv.lock → uv sync, otherwise requirements.txt → pip. Without a lockfile the app still builds, with a warning.

Apps with their own server are prepared in Docker on the user's computer, so Docker Desktop must be installed and running (toupas_doctor, toupas_setup_docker). Static sites don't need it.
