save nodejs history from interactive command-line session

After using node in interactive/command line mode to explore, how can I copy my command history to a text file for my own future records?

The up arrow key recalls previous node statements, and furthermore already persists across logins, so the history is already being saved somewhere in node.js. But where is it saved? How can I copy it?

But I could find nothing in node --help

Solution

  • The read-evaluate-print-loop or REPL has a documented list of special nodejs REPL commands, including a save command:

     .save /path/to/save/my/history

    Also, look in ~/.node_repl_history
