Web development tools allow web developers to test and debug their code. They are different from website builders and integrated development environments (IDEs) in that they do not assist in the direct creation of a webpage, rather they are tools used for testing the user interface of a website or web application.
Some Web Development
Web development tools come as browser add-ons or built-in features in web browsers. The most popular web browsers today, Google Chrome, Firefox, Opera, Internet Explorer, and Safari, have built-in tools to help web developers, and many additional add-ons can be found in their respective plugin download centres. Web development tools allow developers to work with a variety of web technologies, including HTML, CSS, the DOM, JavaScript, and other components that are handled by the web browser. Due to increasing demand from web browsers to do more, popular web browsers have included more features geared for developers.
HTML and the DOM
HTML and DOM viewer and editor is commonly included in the built in web development tools. The difference between the HTML and DOM viewer, and the view source feature in web browsers is that the HTML and DOM viewer allow you to see the DOM as it was rendered in addition to allowing you to make changes to the HTML and DOM and see the change reflected in the page after the change is made.
In addition to selecting and editing, the HTML elements panels will usually also display properties of the DOM object, such as display dimension, and CSS properties.
Web page assets, resources and network information
Web pages typically load and require additional content in the form of images, scripts, font and other external files. Web development tools also allow developers to inspect resources that are loaded and available on the web page in a tree-structure listing. Web development tools also allow developers to view information about the network usage, such as viewing what the loading time and bandwidth usage are and which HTTP headers are being sent and received.
Profiling and auditing
Profiling allows developers to capture information about the performance of a web page or web application. With this information developers can improve the performance of their scripts. Auditing features may provide developers suggestions, after analyzing a page, for optimizations to decrease page load time and increase responsiveness. Web development tools typically also provide a timeline features provides a record of the time it takes to render the page, memory usage, and the types of events which are taking place. These features allow developers to optimize their web page or web application.
Javascript debugging
JavaScript is commonly used in web browsers. Web development tools commonly include a panel to debug scripts by allowing developers to add watch expressions, breakpoints, view the call stack, and pause, step over, step into, and step out of functions while debugging JavaScript. A JavaScript console is commonly included. The consoles allow developers to type in JavaScript commands and call functions, or view errors that may have been encountered during the execution of a script.Tools
1. Sublime Text
Sublime Text is a proprietary cross-platform source code editor with a Python application programming interface (API). It natively supports many programming languages and markup languages, and its functionality can be extended by users with plugins, typically community-built and maintained under freesoftware licenses.
2. Chrome Developer Tools
The Chrome Developer Tools (DevTools for short), are a set of web authoring and debugging tools built into Google Chrome. The DevTools provide web developers deep access into the internals of the browser and their web application. Use the DevTools to efficiently track down layout issues, set JavaScript breakpoints, and get insights for code optimization.
3. jQuery
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.jQuery is a cross-platform JavaScript library designed to simplify the clientside scripting of HTML. It is free, open-source software using the permissive MIT license. Web analysis indicates that it is the most widely deployed JavaScript library by a large margin.
4. GitHub
GitHub is a web-based Git or version control repository and Internet hosting service. It offers all of the distributed version control and source code management (SCM) functionality of Git as well as adding its own features. It provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project. GitHub offers both plans for private and free repositories on the same account which are commonly used to host open-source software projects. As of April 2017, GitHub reports having almost 20 million users and 57 million repositories, making it the largest host of source code in the world.
5. Twitter Bootstrap
Bootstrap is a free and open-source front-end web framework for designing websites and web applications. It contains HTML- and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions. Unlike many web frameworks, it concerns itself with front-end development only.Bootstrap is the second most-starred project on GitHub, with more than 107,000 stars and 48,000 forks.
6. Angular.js
AngularJS (commonly referred to as “Angular.js” or “AngularJS 1.X”) is a JavaScriptbased open-source front-end web application framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. The JavaScript components complement Apache Cordova, the framework used for developing crossplatform mobile apps. It aims to simplify both the development and the testing of such applications by providing a framework for clientside model–view–controller (MVC) and model–view viewmodel (MVVM) architectures, along with components commonly used in rich Internet applications.
7. Sass
Sass is a scripting language that is interpreted into Cascading Style Sheets (CSS). Sass Script is the scripting language itself. Sass consists of two syntaxes. The original syntax, called “the indented syntax”, uses a syntax similar to Haml. It uses indentation to separate code blocks and newline characters to separate rules. The newer syntax, “SCSS”, uses block formatting like that of CSS. It uses braces to denote code blocks and semicolons to separate lines within a block. The indented syntax and SCSS files are traditionally given the extensions .sass and .scss, respectively.
