With chrome dev tool, I can see the number of requests in a page, but it seems that there is no way to measure number of connections. Is it possible in chrome dev tool? if not, what tools can I use instead? You can enable the Connection ID header in the Network panel, which is a unique identifier for a particular connection. You can sort the column to see how many requests there were for a particular connection instance, but there's no built in way to see how many or filter the results. However, this data can be exported into a JSON formatted file, known as the HAR (HTTP Archive). You can do

Check this jsfiddle , and have a look at the console. $$ is not defined. Now, open a completely new window, and enter $$ into a console. It defines a function for getting a (jquery-like) array of all the dom elements which match the selector: > $$ bound: function () { return document.querySelectorAll.apply(document, arguments) } Is this being added by Dev tools? It is also present when using Firebug in Firefox. Is it used internally by the tools themselves? ziesemer Well, Firebug Lite defines this as: this.$$=function(selector,doc){if(doc||!FBL.Firebug.chrome){return FBL.Firebug.Selector

I'm developing an Angular (v4.3.5) SPA, serving it with Angular CLI's ng serve command and debugging it through Chrome Developer Tools. Last week something strange started to happen and I can't seem to do anything to change it to the way it was before: in Chrome Dev Tools, when I click on the line number to add a breakpoint in my .ts files, Chrome Dev Tools also open the corresponding line in main.bundle.ts , so now every single time I add a breakpoint I have to close main.bundle.ts or click back on the title of .ts file. It's very annoying. Is there a new change in default settings or

If you want to look at the CSS of other people's websites (to steal learn from them), Firebug lets you inspect the prettified CSS: But in Chrome 16, you only get the minified CSS as it was served out: Is there a way to get Chrome to prettify the CSS? In the newer versions there is a "format" button that prettifies the source: (only just realised myself :P ) The Developer's console shows the file as served. If you want a human-readable version, copy-paste the code to http://www.codebeautifier.com/ . If you use the Elements tab, the applied CSS properties are also shown per element. I recommend

I've been struggling with this for the past day and there are little-to-no resources available online for integrating Chrome Extensions and Mixpanel. I'd like for this thread to by the one that people refer to when dealing with integrating Mixpanel into a Chrome extension. The goal of my Mixpanel integration is to be able to track events both with my content script content.js as well as my popup.js (so basically across my whole extension) I have a popup.html file that calls <script src="mixpanel.js"></script> right before the </head> tag. In my mixpanel.js file is: (function(e,b){if(!b.__SV)

You can see the word "Document Count" in Chrome DevTools. What is it? For example, recording the below website, the number of documents is 8 or 9. https://developers.google.com/chrome-developer-tools/docs/javascript-memory-profiling?hl=it#dominators This is a question of a tool but I think this could be a question of HTML, so I'm asking here. The "Document Count" maintains a count of the number of documents used by your application over time, that are held in memory (not garbage collected).
