Angular on Azure DevOps running out of memory even with max_old_space_size set

I have an angular project that I recently upgraded to Angular 13. This project is building in Azure DevOps.

About 1 in 3 builds fail due to memory issues. I get lots of different errors each run, but they all are about memory.

I have scoured the internet, and I have been using the max_old_space_size but that doesn't seem to solve my problem. Is there a better way to make the angular build actually use less memory during build?

Here are the 3 errors I often see. Note each run is different, and sometimes it builds fine.

Answer 1

You didn't jot it down so I ask. Did you use command like:

cross-env NODE_OPTIONS=--max-old-space-size=8192 npm build
