Performance issues with Angular CLI

Hello, I have an angular 10 code base but angular CLI takes so long to build I have tried to search what is causing the issue but nothing to seem to work. My laptop speed is just fine and what wrong?

Hi @makuzaverite,

Unfortunately without more information, and a reproduction it's hard for us to investigate this issue and determine a root cause.

In the meantime I'd like to understand what you are experiencing better, can you please answer the below?

• Can you also elaborate on what do you mean by taking long to build, are we talking 2mins, 5mins, 15mins etc?
• Is it slow on the first cold build or all builds?
• Has the speed regressed from previous versions?
• Can you provide the output of ng version?

[veritem]

• The build time takes 10+ mins
• It is slow on the first build
• No this is my new laptop I have installed angular few month ago

Kindly try to update to the latest stable version using the below command.

ng update @angular/cli @angular/core

This should help reduce the the time spent by NGCC to transform the packages. More context: angular/angular#38840
