Save loaded HTML file from electron app

I am trying to explore electron and trying to make a simple Mac application. The problem is that I wanted to save the loaded HTML when user closes the application, and upon next start of application the saved html will be loaded.

Now, consider following case: The html which i have loaded initially have some table and items, and during runtime, via javascript I am adding few new rows and values. So the html is modified at runtime. Now when user closes the app, i have to save this html (which is modified). I tried using webContents.savePage but the page which was saved is the HTML which was loaded initially i.e. without runtime changes. How can I do it?

Also I am not able to catch windows.onbeforeunload event, don't know why. But window.closed is triggerd.

Any help?

You can use the 'close' Event from the BrowserWindow to prevent closing the window in the main process.

You can create a File or Blob object of document

let file = new File([document.documentElement.outerHTML]
           , "file-" + new Date().getTime() + ".html"
           , {type:"text/html", lastModified:new Date().getTime()});
