Long compilation time on running ionic-serve

[Kunalkatdare]

Short description of the problem:

Hi there,

I am building an ionic app, for which I need to store a JSON file locally.
Recently, while running ionic-serve, I ran into JavaScript heap out of memory issue.
I tried increasing the size of the heap after which I had really long compilation time.

I would really appreciate if you could help me out on this.

Some info on my system and Ionic
