electron-context-menu

Context menu for your Electron app

Electron doesn't have a built-in context menu. You're supposed to handle that yourself. But it's both tedious and hard to get right. This module gives you a nice extensible context menu with spellchecking and items like Cut/Copy/Paste for text, Save Image for images, and Copy Link for links. It also adds an Inspect Element menu item when in development to quickly view items in the inspector like in Chrome.

This package can only be used in the main process.

Install

npm install electron-context-menu

Requires Electron 30 or later.

Usage

import {app, BrowserWindow} from 'electron';
import contextMenu from 'electron-context-menu';

contextMenu({
    showSaveImageAs: true
});

let mainWindow;
(async () => {
    await app.whenReady();

    mainWindow = new BrowserWindow();
})();

Advanced example:

import {app, BrowserWindow, shell} from 'electron';
import contextMenu from 'electron-context-menu';

contextMenu({
    prepend: (defaultActions, parameters, browserWindow) => [
        {
            label: 'Rainbow',
            // Only show it when right-clicking images
            visible: parameters.mediaType === 'image'
        },
        {
            label: 'Search Google for “{selection}”',
            // Only show it when right-clicking text
            visible: parameters.selectionText.trim().length > 0,
            click: () => {
                shell.openExternal(`https://google.com/search?q=${encodeURIComponent(parameters.selectionText)}`);
            }
        }
    ]
});

let mainWindow;
(async () => {
    await app.whenReady();

    mainWindow = new BrowserWindow();
})();

The return value of contextMenu() is a function that disposes of the created event listeners:

const dispose = contextMenu();

dispose();
