# DFG 3D Viewer — JavaScript Library

Three.js-based 3D viewer. Ships as a minified bundle for `web/libraries/dfg-3dviewer/` or standalone HTML embeds.

**Drupal integration** is provided by the separate [`dfg_3dviewer`](https://gitlab.nasarek.dev/rnsrk/dfg_3dviewer_drupal_module) module.

## Build

```bash
npm install
npm run build:library
```

Output in `dist/library/`:

- `dfg_3dviewer.min.js`
- `assets/` — CSS, draco, IFC WASM, fonts

For local packaging (optional):

```bash
npm run pack:library   # creates dfg-3dviewer-library.zip (gitignored)
```

## Releases

Tagged pushes build `dfg-3dviewer-library.zip` in CI and attach it to a GitLab Release.

```bash
git tag v1.0.3
git push origin v1.0.3
```

Download the zip from [Releases](https://gitlab.nasarek.dev/rnsrk/dfg_3dviewer_js_library/-/releases) and extract to `web/libraries/dfg-3dviewer/` on Drupal.

## Local development

```bash
cp viewer/viewer-settings-example.json viewer-settings.json
npm run dev:test
# http://localhost:1234
```
