For others also seeking help with this, the issue is known to plague the CLI (#1652, #2974) when projects grow beyond what many of us consider small-medium sized codebases.

As you mentioned, the fix it to set Node's heap size. This is done with node --max_old_space_size=[Space in MB] followed by whatever call you wanted to make, e.g. node --max_old_space_size=2048 ./node_modules/.bin/ng build (Credit to @hansl for that one line.)
