# Try It 🚀
### Requirements
- [Node.js](https://nodejs.org/en/download/) 22+
- [Yarn](https://classic.yarnpkg.com/)
### Development
`build:prebuild` generates the file system and search indexes the app loads at startup, so re-run it after adding or removing files in `public/`.
```sh
yarn install
yarn build:prebuild
yarn dev
```
Then open http://localhost:3000.
### Production
Builds a static export to `out/` and serves it on http://localhost:3000.
```sh
yarn install
yarn build
yarn serve
```
### Docker
```sh
docker build -t daedalos .
docker run -dp 3000:3000 --rm --name daedalos daedalos
```
### Tests & Linting
```sh
yarn test # Jest unit tests
yarn e2e # Playwright end-to-end tests (run `yarn playwright install` once first)
yarn lint # Oxlint
```
