Nextcloud Draw.io / Diagrams.net integration app

This app allows users to create and edit diagrams in Nextcloud using Draw.io / Diagrams.net on-line editor.

Mimetype detection

To make Draw.io work properly, you need to add a new mimetypes in the mimetypemapping.json file (at Nextcloud level).

Go to Admin settings > Additional settings ( /index.php/settings/admin/additional ) and click the Save button to register MIME types.

Or you can do it manually:

• Download mimetypemapping.json and save it in config folder or
• Copy /resources/config/mimetypemapping.dist.json to /config/mimetypemapping.json (in the config/ folder at Nextcloud’s root directory; the file should be stored next to the config.php file). Afterwards add the two following line just after the “_comment” lines. "drawio": ["application/x-drawio"],

If all other mimetypes are not working properly, just run the following command:

sudo -u www-data php occ files:scan --all
