Can you check if a user is viewing a webpage using Electron?

Question

Let's say I want to build a simple Electron app that alerts the user when he reaches example.com

Would this be possible? And if so, how would I detect if the user is viewing a certain webpage?

Answer 1

Electron has the did-navigate event which is fired when a page is redirected inside a BrowserWindow .

Referring to the above post I think,

const { BrowserWindow, dialog } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })

win.webContents.on('did-navigate', (event, url, httpResponseCode, httpStatusText) => {
    if(url == "example.com") {
        dialog.showMessageBox({ type: "info", message: `You visited ${url}` });
        //dialog docs at https://www.electronjs.org/docs/api/dialog#dialogshowmessageboxbrowserwindow-options
    }  
})
