# Environment Variables

> Control application configuration and behavior without changing code.

Certain Electron behaviors are controlled by environment variables because they
are initialized earlier than the command line flags and the app's code.

Examples on POSIX shells:

```bash
$ export ELECTRON_ENABLE_LOGGING=true
$ electron
```

on Windows console:

```powershell
> set ELECTRON_ENABLE_LOGGING=true
> electron
```

### `ELECTRON_RUN_AS_NODE`

Starts the process as a normal Node.js process.

### `ELECTRON_ENABLE_LOGGING`

Prints Chrome's internal logging to the console.

### `ELECTRON_LOG_ASAR_READS`

When Electron reads from an ASAR file, log the read offset and file path to
the system `tmpdir`. The resulting file can be provided to the ASAR module
to optimize file ordering.

### `ELECTRON_ENABLE_STACK_DUMPING`

Prints the stack trace to the console when Electron crashes.

This environment variable will not work if the `crashReporter` is started.

### `ELECTRON_DEFAULT_ERROR_MODE` _Windows_

Shows the Windows's crash dialog when Electron crashes.

This environment variable will not work if the `crashReporter` is started.

### `ELECTRON_NO_ATTACH_CONSOLE` _Windows_

Don't attach to the current console session.

### `ELECTRON_FORCE_WINDOW_MENU_BAR` _Linux_

Don't use the global menu bar on Linux.
