Question

For example, I want to disable the new heap snapshots so I type something like this:

node --new_snapshot=false

But I get an error: Error: illegal value for flag –new_snapshot=false of type bool

What am I missing about the syntax?

Answer 1

I had to dig into v8 source code to get this. For some reason I couldn’t find it documented. However, a boolean option is enabled by setting --option and disabled by using --nooption (note the no prefix).

So in your case use

node --nonew_snapshot
