从交互式命令行会话中保存nodejs历史记录

Question

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

Answer 1

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

Answer 2

you just need to run this command

node app.js > log.txt

this command will save all command prompt output to a file
