I created a basic ionic2 application a few weeks ago (still using beta11) and it all worked fine. I was using a .json file with hardcoded json as a datasource. This json file was copied to the /build folder using the app-bundle task located in the gulptasks folder.
Now, I have just created a new ionic2 application and asides from the folder structure that is quite different, gulp seems to be gone completely.
So how should I copy files to the /build folder ? Do I have to install gulp and create every taks myself ? I’m not very familiar with using gulp (in the previous app I created, gulp was already there and I just hacked the app-bundle task).
