JavaScript heap out of memory error.
Question.
I have an JavaScript heap out of memory error.
How to resolve?
Answer.
Sometimes, when processing a large data set, for example a large CSV file (~>100Mb), you may face nodejs memory issue, such as: "Allocation failed - JavaScript heap out of memory".
Try to extend available nodejs memory heap by executing the following command:
# For the Windows OS:
set NODE_OPTIONS=--max-old-space-size=8192
# For the MAC/LINUX OS:
export NODE_OPTIONS=--max-old-space-size=8192
This example of the command extends the maximum allowed memory size up to 8Gb.
