node.js - Puppeteer: How to listen to a specific response?

Question

I'm tinkering with the headless chrome node api called puppeteer.

I'm wondering how to listen to a specific request response and how to act in consequence.

I have look at events requestfinish and response but it gives me all the request/responses already performed in the page.

How can I achieve commented behaviour?

Thanks !

One option is to do the following:

  page.on('response', response => {
    if (response.url().endsWith("your/match"))
      console.log("response code: ", response.status());
      // do something here
  });

This still catches all requests, but allows you to filter and act on the event emitter.
