# Examples

xx provides managed language tools and general command tasks.

- [Go builds](go.md): Build source files and package directories, set outputs and flags, and use the managed Go SDK directly.
- [Node.js tasks](nodejs.md): Install dependencies, run package scripts, invoke Node.js directly, and use npx.
- [Commands and environments](commands.md): Run project tools, define reusable environments, and organize multiple entrypoints.

Examples assume files are inside a project whose build entrypoints live in `.xx/`. Run `.xx/build.star` with:

```console
xx run build
```

Entrypoint names do not include `.xx/` or the file extension.
