For example, if I have 3 tabs, with one tab showing map. I would like to have map related js library only in that tab. However if I put it in index.html it will be loaded no matter where I am. Any way to do this? Thanks.
You should have a look into requirejs:
I am building my whole apps with requirejs to have a modular clean project structure for development.
(At the end i have a build script that minifies and combines everything in one js-file)
I have written a tutorial some time ago in german:
But you have also the possibilty to load the ionic.bundle in your index.html before your requirejs config and only use require for your app parts and libs.
Thank you so much. It looks quite complicated.
