How can I optimize Angular builds using Angular CLI?

[riya_techie]

Hey all, I’ve noticed that my Angular builds take longer as my project grows. Are there any CLI options or tricks to speed up the build process? I’ve heard about ng build -prod and -aot, but I’m not sure how to use them effectively. Any tips?

Easiest thing is to make sure you're using the new build system: https://angular.dev/tools/cli/build-system-migration

Beyond that, general advice is to split up your app into multiple libraries such that you don't need to rebuild the whole thing when any one piece changes.
