REPL

Read-Eval-Print-Loop (REPL) is a simple, interactive computer programming environment that takes single user inputs (i.e. single expressions), evaluates them, and returns the result to the user.

Main process​

Electron exposes the Node.js repl module through the --interactive CLI flag. Assuming you have electron installed as a local project dependency, you should be able to access the REPL with the following command:

./node_modules/.bin/electron --interactive

Note: electron --interactive is not available on Windows (see electron/electron#5776 for more details).

Renderer process​

You can use the DevTools Console tab to get a REPL for any renderer process. To learn more, read the Chrome documentation.
