Angular-cli 'JavaScript heap out of memory' on asset optimization

I'm creating a leaflet map inside an Angular-cli project. Map tiles are stored locally in the 'assets' folder because it's a raster map. The problem is when I've many zoom levels of the map, I've more than 280 thousands images with approximate size of 1.1 GB and It will get bigger.

when I use ng serve here is the console output (it is stuck @ assets optimization):

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

I tried using: node --max_old_space_size=8192 --optimize_for_size --max_executable_size=4096 --stack_size=4096, but It doesn't make any difference.

1- Is there is any other way to avoid optimizing all the assets folder? If it is the source of the problem as I think, because the project were running smoothly before adding more leaflet tile images.

2- Is there are any workarounds to solve this issue?

UPDATE: There is an open issue at Angular-cli repository related to this question.

Add the below line to package.json file.

"aot": "node --max-old-space-size=8192 ./node_modules/@angular/cli/bin/ng build --prod --aot"

and try running with npm run aot

It worked for me.
