HTML5 débogage: WebKit Web Inspector - Mindshare - Universal Mind. One of the major challenges with HTML and JavaScript in the past has been debugging. Simply put, it didn’t exist. Along with the lack of compile-time type checking, debugging has been one of the biggest challenges with developing HTML5/JavaScript applications. Enter the WebKit Web Inspector. WebKit is the open-source layout engine that powers Apple Safari, Google Chrome, and the mobile web browsers on nearly all modern mobile phones and tablets, including: iPhone, iPod and iPad; all Google Android phones and tablets; Amazon Kindle; Barnes and Noble's Nook; and RIM's BlackBerry PlayBook.
WebKit includes a set of integrated developer tools for interactively prototyping, analyzing, debugging, and optimizing websites and web applications. Collectively, these tools are referred to as “Web Inspector”. Web Inspector provides a live view into the HTML, CSS, and JavaScript content being rendered, paired with an advanced JavaScript debugger and interactive command console. Elements View Network View.

Posted by Timothy Hatcher on Monday, January 16th, 2006 at 10:36 pm I would like to introduce a new addition to WebKit—the Web Inspector. The Web Inspector lets you browse the live DOM hierarchy in a compact HUD style window, catering to the needs of web developers and WebKit hackers alike. The Web Inspector highlights the node on the page as it is selected in the hierarchy. You can also search for nodes by node name, id and CSS class name.
One of the unique features of the inspector is the ability to root the DOM hierarchy by double clicking a node to dig deeper. This lets you easily manage large nested pages and only focus on a particular sub-tree with minimal indentation. Under the Style pane we show all the CSS rules that apply to the focused node. So update your tree or download the nightly and give the new Web Inspector a try. Defaults write com.apple.Safari \WebKitDeveloperExtras -bool true You will then see a new “Inspect Element” contextual menu item on any web page. TitleIndex. Remote Debugging in WebKit Web Inspector. In a blog post Pavel Feldman explains how to use WebKit Web Inspector outside of the target browser. WebKit Inspector can communicate with WebKit-based browsers through the Remote Debugging Protocol, providing a debugging environment very similar to the one found locally.
Some reasons to use Web Inspector this way include debugging mode applications and IDE integration. However, from what I can tell, Safari on iOS and Chrome on Android don't yet support the Remote Debugging Protocol. From the blog post, here's a list of the domains supported by the protocol so far: Console - defines methods and events for interaction with the JavaScript console. CSS - exposes low level CSS read / write operations. Ce que les utilisateurs Web doivent savoir au sujet SPDY. Slowly but surely, SPDY ("speedy") is becoming more widely used. The Google-backed protocol, a modification to HTTP, is designed to help reduce latency and bolster security.
Even if you don't manage a Web server yourself, you should know about SPDY and what it offers to you - and the Web at large. SPDY has been in development for a couple of years, but a few things will start to accelerate its deployment. First, Google has put out a SPDY module for Apache, which will make it much easier for organizations to deploy SPDY. Nginx is expected to have an implementation by end of May. That covers a huge chunk of the server market already. Second, SPDY should be on by default in Firefox 13, and Chrome (and Chromium) already supports SPDY. What SPDY Is, and What It Offers SPDY is a two-layer HTTP-compatible protocol.
The lower layer of SPDY provides a number of benefits over standard HTTP. A single SPDY session allows concurrent HTTP requests to run over a single TCP/IP session. Security.
