After making some changes in my TypeScript files, each build takes over 20 minutes. I run this command: ng build --output-path=..\..\static\angularjs.
If I run it in Microsoft PowerShell, it needs 25 - 30 seconds. This is a lot of time.

How can I speed this up?

reason: In the Angular 12 version, run ng build, and now the default is production mode. This is a welcome change because it reduces the chance of inadvertently deploying a development build to a production environment, which is much slower and much larger, making it feel like Angular is very slow.
Created by the Angular team, Build Optimizer is a tool that further optimizes Angular Webpack builds. It identifies code that can be removed at build time without side effects. For instance, Build Optimizer can remove Angular decorators like @Component from AOT builds.
The ng build command writes generated build artifacts to the output folder (by default is -dist/). The ng serve command does not write build and it builds artifacts from memory instead for a faster development experience. This command builds your app and deploys it.
The ng build command with the --prod meta-flag (ng build --prod) compiles with AOT by default. Why compile with AOT? With AOT, the browser downloads a pre-compiled version of the application. The browser loads executable code so it can render the application immediately, without waiting to compile the app first.
My app took 28secs to build, but I've reduced the time to 9secs. Usings this flag
ng build --source-map=false you can see the difference in time comparing the time:
ng build --stats-json ng build --stats-json --source-map=false source map is intended only for debugging, Hope it helps
