I keep getting this error preventing HMR from working when I use AddNodeServices and UseWebpackDevMiddleware:

fail: Microsoft.AspNetCore.NodeServices[0]
      FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
      An unhandled exception has occurred while executing the request

Is it possible to specify the argument max_old_space_size when starting node?
