Angular Project Build went from 12MBs to 90MBs after upgrading from angular 8

Issue

Build command currently using.

node pre-build && node --max_old_space_size=6144 ./node_modules/@angular/cli/bin/ng build --prod --build-optimizer --outputHashing=all

Solution

In your angular.json try adjusting these properties

optimization to true

aot to true

buildOptimizer to true

It will enable optimizations like tree shaking and get rid of unnecessary code.
