Ionic serve: rerun gulp task on change

Hello all :smile:

I build a gulp task that minifying all my js, sass and html files.
And I want that when I run ionic serve, and when some files changes it will rerun the gulp task that are running on startup

I saw some post here regarding that topic but it didnt help.
Is that even possiable?

for more information(ionic.project, and gulpfile.js ) take a look here:

Anyone know if this is possible?
