node.js - how to increase nodejs default memory?

Question

On Server startup exporting 2GB(Approximately) data from mongodb to redis,then getting error as FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory.

Then started server with this command node --max-old-space-size=4076 server.js and works fine. But needs to configure in nodejs applicaton so that node server always starts with 4gb memory. Please help me how to fix this? Thanks.
