Hey Guys,
I have been working on a app since a very long time (like 1 year back) it was stopped but lately we decided to reboot it. It was working fine with the ionic which it had, we never really bothered to update just kept working and added all the changes.
Since most of the app was done we decided to add ionic-cache and then we started facing typescript errors and one of the guy from the team said, “its time we should do npm update” and we did that and since then our app has totally stopped working 
I dont know what is happend and whats wrong but here is the dump of bucket of errors that we get while cli does transpile
[11:31:38] transpile started ...
