Performance issues when running npm start in my Angular project

[ArielGueta]

Hey everyone,

I’m experiencing significant performance issues when running my Angular app using npm start. The startup process (which launches the development server with ng serve) has become noticeably slow — it takes much longer than expected to compile or reload.

I’m looking for ways to debug and identify what’s causing the slowdown.

What I’d like to know:

How to profile or trace what happens during ng serve

How to detect slow TypeScript compilation or file watching issues

How to identify large dependencies or misconfigured build options

Any advice, tools, or debugging techniques to improve Angular dev server performance would be greatly appreciated.

Thanks!
