Electron exposes the [Node.js `repl` module](https://nodejs.org/dist/latest/docs/api/repl.html)
|
|
|
|
|
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:

|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
./node_modules/.bin/electron --interactive
|
|
|
|
|
```

**Note:** `electron --interactive` is not available on Windows

(see [electron/electron#5776](https://github.com/electron/electron/pull/5776) for more details).
