Raw simply returns any requested file, so you can link directly to a file itself (i.e. without any of NextCloud’s interface around it). This enables you to host static web pages, images or other files, for example to link/embed them elsewhere on the web.
For security and privacy, the content is served with a Content-Security-Policy header. This header instructs browsers to not load any remote content, nor execute any scripts that it may contain (of course, the downside is that your web pages cannot use javascript for interactivity).
The common usage is to first share a file and enable public access through a link. If the share link
is https://my-nextcloud/s/aBc123DeF456xyZ, then this app will provide access to the raw file at
https://my-nextcloud/apps/raw/s/aBc123DeF456xyZ. If the share is a folder, the files within it
are accessible as e.g. https://my-nextcloud/apps/raw/s/aBc123DeF456xyZ/path/to/file.
A user can also access their own private files. For example, a file named test.html in anansi’s
Documents folder would be available at https://my-nextcloud/apps/raw/u/anansi/Documents/test.html.
Clone this repo into your Nextcloud installation’s /apps (or /custom_apps) folder, ensuring the
folder’s name is raw:
git clone https://code.treora.com/gerben/nextcloud-raw raw
Then log into Nextcloud as admin, find and enable it in the list of apps.
This app is currently not published in the Nextcloud app store.
