# 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.
|
||||
[Read-Eval-Print-Loop](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_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.
|
||||
|
||||
The `repl` module provides a REPL implementation that can be accessed using:
|
||||
## Main process
|
||||
|
||||
* Assuming you have `electron` or `electron-prebuilt` installed as a local
|
||||
project dependency:
|
||||
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
|
||||
```
|
||||
|
||||
* Assuming you have `electron` or `electron-prebuilt` installed globally:
|
||||
**Note:** `electron --interactive` is not available on Windows
|
||||
(see [electron/electron#5776](https://github.com/electron/electron/pull/5776) for more details).
|
||||
|
||||
```sh
|
||||
electron --interactive
|
||||
```
|
||||
## Renderer process
|
||||
|
||||
This only creates a REPL for the main process. You can use the Console
|
||||
tab of the Dev Tools to get a REPL for the renderer processes.
|
||||
|
||||
**Note:** `electron --interactive` is not available on Windows.
|
||||
|
||||
More information can be found in the [Node.js REPL docs](https://nodejs.org/dist/latest/docs/api/repl.html).
|
||||
You can use the DevTools Console tab to get a REPL for any renderer process.
