useFileOpener

The one way every files component opens a file. open(file) tries, in order:

  1. Nextcloud's Viewer, when it is loaded (window.OCA.Viewer) and handles the file's mime type.
  2. CnFilePreview for CSV, TSV, JSON, XML and text, through the onPreview callback (the host renders the dialog).
  3. The browser in a new tab for PDF and images, through a URL validated by safeHref (a javascript: URL never opens).
  4. The Files app permalink (/f/{id}).

It returns which way opened the file: 'viewer', 'preview', 'browser', 'files' or 'none'. On a public page the Viewer is not loaded, so PDFs and images open in the browser's own viewer and data files in the preview.

import { useFileOpener } from '@conduction/nextcloud-vue'

const { open, viewerHandles } = useFileOpener({
  onPreview: (file) => { this.previewFile = file },
})
open({ id: 5, name: 'Besluit.pdf', type: 'application/pdf', path: '/Besluit.pdf', accessUrl: '/s/abc' })
OptionDescription
onPreview(file)Called when the file should open in CnFilePreview. Without it step 2 is skipped.
userRelativePath(path)Maps a stored path to the Viewer's user-relative path.
anyAccessUrlAlso open any other type through its access URL before the Files app.
filesAppUrl(file)Builds the Files app URL; defaults to the /f/{id} permalink.
