Description
BPMN diagrams usually live in designer tools (bpmn.io, Camunda Modeler, Signavio) and rarely make it into the apps that execute them. This package closes that gap: upload a .bpmn file from any Nova resource and the interactive process diagram shows up right on the record, with pan, zoom, and minimap — powered by bpmn-js. Compatible with Nova 5.

Installation
You can install the package in to a Laravel app that uses Nova via composer:
The package will auto-register its service provider.
Back your field with a string column on the owning model — it stores the disk path of the uploaded .bpmn. The file itself lives on the Laravel disk of your choice (typically public).
Make sure the disk is publicly readable (for the default public disk: php artisan storage:link).
Usage
Add the BPMN field to any Nova Resource that owns a BPMN attribute:
On Create / Update the field renders Nova’s native File dropzone — pick a .bpmn or .xml file, it is uploaded to the configured disk and the path is persisted. On Detail / Lens the field fetches the file from the disk and renders the full interactive viewer. It is intentionally hidden from Index.
Field behavior
| View | Behavior |
|---|---|
| Create / Update | Nova’s native File field dropzone (.bpmn, .xml). Inherited storage, deletion, and ->prunable() semantics. |
| Detail / Lens | Interactive bpmn-js NavigatedViewer with pan, zoom, fit-to-viewport, and optional minimap. |
| Index | Hidden — a full process diagram inside a table cell adds no decision-making value. |
Modifiers
| Method | Purpose |
|---|---|
->height(int $pixels) |
Canvas height in pixels (default 600). |
->minimap(bool $enabled = true) |
Enable the minimap overlay. |
->zoomControls(bool $enabled = true) |
Show the in-canvas zoom in / out / reset buttons. |
->prunable() / ->deletable() |
Inherited from Laravel\Nova\Fields\File — remove the stored file when the record is deleted or the field is cleared. |
Under the hood
| Layer | Dependency |
|---|---|
| Upload / storage | Laravel\Nova\Fields\File — disk-backed upload, deletion, prunable. |
| Renderer | bpmn-js NavigatedViewer. |
The PHP field class is a thin subclass of Nova’s File; the Vue form and index slots alias form-file-field and index-file-field verbatim, so there is no custom upload UI to maintain. Only the detail slot is custom — it reads field.previewUrl, fetches the XML, and mounts the viewer.
