Detect an Electron instance via JavaScript

rated 0 times [ 179] [ 7] / answers: 1 / hits: 6068 / 4 Years ago, mon, may 11, 2020, 12:00:00

I have a webapp which will run on a website and as a standalone Electron instance (.exe for Windows).

I'd like to tell via JavaScript if the webapp is running inside ElectronJS or not, in order to display some extra features for the online version. Is there any way to detect the Electron framework instance? I'd like to avoid writing two slightly different versions of the webapp.

Just use this code (got it from is-electron library)

function isElectron() {

    // Renderer process

    if (typeof window !== 'undefined' && typeof window.process === 'object' && window.process.type === 'renderer') {

        return true;

    }



    // Main process

    if (typeof process !== 'undefined' && typeof process.versions === 'object' && !!process.versions.electron) {

        return true;

    }



    // Detect the user agent when the `nodeIntegration` option is set to true

    if (typeof navigator === 'object' && typeof navigator.userAgent === 'string' && navigator.userAgent.indexOf('Electron') >= 0) {

        return true;

    }



    return false;

}
