Answer 1

For production builds you can use ionic cordova build [android/ios] --prod --release. This can reduced the size of your application.

The prod and release flags will minify code and remove debugging utilities.

Answer 2

You can use one of $ ionic cordova build options

• --no-build - Do not invoke an Ionic build
• --prod - Build the application for production
• --aot - Perform ahead-of-time compilation for this build
• --minifyjs - Minify JS for this build
• --minifycss - Minify CSS for this build
• --optimizejs - Perform JS optimizations for this build
• ...

For example: ionic cordova build android --prod --aot
