Size of main.js = 20mb and size of vendor.js = 7.84mb, what could be the issue and how can I optimize my build?

I tried using ng build --prod which gives error for version 15.2-15.3

Do you have `"optimization": false` in your `angular.json` file? This could cause large builds. https://angular.io/guide/workspace-config#optimization-configuration – Get Off My Lawn Dec 23 '22 at 19:59
No, "optimization" is true in my angular.json file. – Anushka Sen Dec 24 '22 at 03:55

Have you tried analyzing it with the [bundle analyzer](https://www.npmjs.com/package/webpack-bundle-analyzer)? – Get Off My Lawn Dec 24 '22 at 07:22
You can probably use `gzip compression` to compress the static or dynamic files – Ashish Duklan Jan 30 '23 at 06:58
