I have a script foo.js that contains some functions I want to play with in the REPL.

Is there a way to have node execute my script and then jump into a

Answer 1

Why not load the file into an interactive node repl?

node -h
-e, --eval script          evaluate script
-i, --interactive          always enter the REPL even if stdin

node -e 'var client = require("./build/main/index.js"); console.log("Use `client` in repl")' -i

Then you can add to package.json scripts

"repl": "node -e 'var client = require(\"./build/main/index.js\"); console.log(\"Use `client` in repl\")' -i",

tested using node v8.1.2
