javascript - angular-cli uses ng build --prod and ng build --prod --aot to package files with the same size?

Question

1. The size of my complete project after compilation using ng build --prod is 1713k, as shown in the picture
   

2. After using ng build --prod --aot the size is still 1713k;
   

3. --Does aot need other configuration parameters to be effective?
   

4. In other words, before using the --aot parameter, tree shaking optimization is also required?

Answer 1

Answer 2

--prod turns on --aot by default, so using --prod and --prod --aot are the same
