repl.history

Persist a node repl's history to a file (now working with node v16+).

from node

install: npm install repl.history

const os = require('os');
const path = require('path');

const historyFile = path.join(os.homedir(), '.node_history');

const repl = require('repl').start('> ');
require('repl.history')(repl, historyFile);

this will drop a .node_history file in your home directory.

from the command line

install: npm install -g @andfaulkner/repl.history

run repl.history on the command line

A file ~/.node_history will be created.

I like to alias it to nr for node repl. To do this, add the following to your ~/.bashrc file:

alias nr="repl.history"
