Please update to Node.js 10, and try again

The docs state that you need the latest version of Node.js and npm

aw, maybe we can update more detail that developer should use node 10 ✌️

@abennouna After update to Node.js 10+, livereload is fastest (6sec), but still poor. How many seconds livereload took you?

Well I guess it depends on the machine and the project. I'm on a i5/8GB MBP and for this project, a simple template modification takes 7.5s:

[ng] ℹ ｢wdm｣: Compiling...
[ng]
[ng] Date: 2018-12-21T13:48:06.150Z - Hash: f30c6d43bc6045e42824 - Time: 7462ms
[ng] 172 unchanged chunks
[ng] ℹ ｢wdm｣: Compiled successfully.

However, a simple .scss change is a bit faster:

[ng] ℹ ｢wdm｣: Compiling...
[ng]
[ng] Date: 2018-12-21T13:50:31.532Z - Hash: f30c6d43bc6045e42824 - Time: 4670ms
[ng] 172 unchanged chunks

Thanks for the issue! ng serve is an Angular command and ionic serve runs it directly.

As of Ionic 4, Ionic no longer ships with custom Angular build tools. This means any build issues you experience should be considered Angular build issues and should be brought up with the Angular team.

I'm going to close this as I do not think it is an Ionic issue. Thanks!
