It crash with large number rows (> 10k rows) as out of heap memory

[minhngl]

I call �function "substitute" with data arrays of more than 10K rows, it crash as Javascript out of memory

template.substitute(sheetNumber, array_of_data);

Is there any way to avoid this?

Thanks.

That's the V8 engine running out of memory. By default, node uses a max of 1 or 2 GB of memory (depending on version).
The solution is to just give node more memory. Try running your script with the --max-old-space-size flag like this (change 8192, which means 8GB, to whatever you find suitable):
node --max-old-space-size=8192 your_script.js
