Update file content after seconds if the content of the file changes.

[Thiemo Melhorn]

Hello everyone, 

I would like to know what the code for updating a file is called. I have already made it so that when a file is selected, it is also displayed in the tab of my web browser. Now I would like the new tab with the file to be updated when the file changes.

DS does not support the FileObserver object, but you could either - 

1. Use setInterval() to run a callback that checks if the file date has changes and refresh the browser if so.

2. Write a DS plugin to make use of the FileObserver

3. Try using a Node.js background task to watch for changes (never tried this)
