I'm looking for a solution to allow users to edit files (mostly Word, but other should be possible as well) on the client machine (no add-ins as they need the full-blown editor) without having to manually download and then reupload the file to the webapplication (Java - Spring - Angular). The documents should behave as it would be a local document but upon close/save it should be saved in the webapplication. If possible without having to install something on the client.
Current ideas:
- Add macro code to the file (pre-download) that has information about the server/storage and gets executed upon close/save
- HTML5-FileAPI, but unsure if it is suitable for this use case
