According to StatCounter, Google Chrome is becoming the most popular web browser that extremely pushes Firefox and Internet Explorer out of the browser market. Such a meteoric rise in popularity has become possible, thanks to Chrome's performance and a lot of useful built-in features. This fact influences the choice of many developers who choose Google Chrome as their debugging browser. Here, we take a look at some Google website developer tools that make Chrome a rather compelling environment for web developers. Let's figure out what helpful components Chrome Developer Tools include.
Called DevTools, this built-in set is really good for web development and debugging. Here, you can find different included panels for Elements, Network, Sources, Timeline, Profiles, Resources, Audits, and Console. To open DevTools, select the Chrome hamburger menu at the top right of your browser window, enter More Tools and then choose Developer Tools. Once they are open, you can use Ctrl+ to move from panel to panel. DevTools are commonly used for examination of the HTML and CSS for a web page element that is currently displayed in Chrome. To achieve this, click the Elements tab in the DevTools navigation bar. Also, these Google tools for web developers allow live-edit CSS, that makes it possible to see how the altered the look of a page in progress is without making a trip to the code editor.
This is one of the Google development tools. It is used to look at suggestions on how to improve the performance of the current web page in Google Chrome.
Network tab is needed for showing a timeline and list current pages's HTTP requests and responses. Even when you watch the page, it continues to update. Note, you will see fewer requests if you had enabled the cache before. Also, you can easily filter what you see so that they do not drill down on all the specific items that take a long time. It really helps to know what is going on in the script or the page initiating each request.
4 PageSpeed Insights
This product has been recently folded into Google web development tools, it was a separate tool at first. Click on the rule names and go down to additional information and implement the suggested changes.
Talking about page performance, make a note of YSlow – Google Chrome extension for understanding why a certain page may be performing slowly. Despite its similarity to PageSpeed Insights, both tools are used by the developers. You will see YSlow's recommendations for remediation when you click on the test result. But don't be blindy and change everything that was suggested, including suggestions that might not be applicable to responsive website development.
To see how a web page spends its time use the DevTools timeline. You will see a graphic where the time spent in loading, rendering, scripting and other operations is denoted.
7 Device emulation
Test web page responsive designs with the Chrome device emulation. It includes generating touch events from a mouse. It is helpful when developing a mobile web or hybrid app; you may get more than 95 percent of what you need to know about how the project will look on a device without it usage. To start mobile emulation, enter the smartphone device icon in the DevTools navigation bar. There is a wide choice of smartphones and tablets to emulate an app and a big variety of network types to see how a page performs.
These are the main Google website development tools, that developers use when creating both web sites and mobile apps. Also there are Chrome Inspect Devices, Web Developer extension, Firebug Lite, WebStorm and NetBeans Connector that are good complements to Google DevTools.
