Open external links in default browser from Electron

Understanding Electron and External Links

Electron is a powerful framework that enables developers to build cross-platform desktop applications using web technologies. When creating an app, you might encounter scenarios where users will click on external links. By default, these links might open in the Electron application itself, which can be less user-friendly. Therefore, it's essential to know how to force these links to open in the user's default web browser.

Why Open External Links in Default Browser?

Opening external links in the default browser instead of the Electron app can enhance the user experience. Users typically prefer to navigate in a familiar environment where they have their bookmarks, extensions, and other browsing preferences set. It also helps in maintaining focus within the application without overwhelming users with new content windows.

Implementation Steps

Now that you understand the importance, let’s explore how to implement this feature in your Electron application. This process involves using the 'shell' module provided by Electron. Here’s how you can set it up accurately.

Follow these implementation steps:

• Import the 'app' and 'shell' modules from Electron.
• Listen to the 'will-navigate' event on the web contents.
• Use the shell.openExternal() method to open the link in the default browser.

Sample Code to Open External Links

To give you a clearer understanding, below is a sample implementation code scenario detailing how to achieve this.

Opening Links in Default Browser Example

const { app, shell } = require('electron');

app.on('ready', () => {
    const win = new BrowserWindow({/* your window options */});

    win.webContents.on('will-navigate', (event, url) => {
        event.preventDefault(); // prevent default navigation
        shell.openExternal(url); // Opens the link in the default browser
    });

    win.loadURL('your-app-url');
});

Testing Your Changes

Once you have implemented the above code in your application, the next step is thorough testing. Launch your Electron app and try clicking on external links to verify that they correctly open in the default browser without any glitches.
