When developers use webContents‘s will-prevent-unload event,
They want to ask the user to confirm something most of the time.
Like this:

win.webContents.on('will-prevent-unload', event => {
    let choice = dialog.showMessageBoxSync({
      title:'do you want to close',
      buttons:['cancel','yes']
    });
    if(choice === 1)  event.preventDefault();
    //...
  })
`

Error:

NoMethodError: undefined method `relation_delegate_class' for Comment:Module

Since version 0.16.5, th following code returns a null worksheet:
XLSX.utils.json_to_sheet([], {header: columns})

Is it now working as it is wanted? If so, how could we create an empty worksheet? In my case it is expected that sometimes the data is an empty array. And an empty worksheet only with headers is expected.

Most appropriate sub-area of p5.js?

If you're using proxies with requests-html and rendering JS sites is all good. Once you render a website pyppeteer don't know about this proxies and will expose your IP. This is an undesired behavior when scraping with proxies.

The idea is that whenever someone passes in proxies to the session object or any method call, make pyppeteer also use these proxies. #265
