Node.js heap out of memory

Question

When I tried to run the script for filesystem, but it crashes with an error:

[md5:]  241613/241627 97.5%  

[md5:]  241614/241627 97.5%  

[md5:]  241625/241627 98.1%

Can anyone help me with this?

Answer 1

Basically, it has a strict limit of 1.7 GB, but we can increase it manually.

node --max-old-space-size=4096 yourFile.js

The above command will help you increase the size.

I hope this will help.
