Web Components for Web Development - Is It Known or Still Foreign to Most?

Developers frequently explore options to optimize the internet application’s look, feel and performance. The innovative technologies like web components make these easier for them to add a higher level of interactivity and visual richness to the websites and recyclable widgets by using multiple components. Thus, the term web content can be defined as a collection of components used widely for website development including images, bitmap, JavaScript or PHP.

In addition to allowing developers to bundle styles and markups into custom HTML elements, the web components further facilitate encapsulation of HTML and CSS to avail enhanced code security. So the web components are used widely by modern internet developers to build websites and recyclable widgets with the help of HTML, JavaScript and CSS. If you are not familiar with web components, it is a good idea to understand some of these commonly used web components.

Five Essential Elements of the Web Components

1) Templates
Similar to other software development projects, website development also needs a solid blueprint. The web components provide the blueprint for a project through the tag. The tag enables programmers to store specific markup on the page that can be reused and cloned subsequently. The developers familiar with handlebars, moustaches and similar libraries can understand and use the tag immediately. As the markup inside a template are not recognized by web browsers, it becomes easier to include non-executable tags for images, videos and audio having external sources.

2) Decorators
Unlike other web components, decorators are yet to have a specification. The decorator components can, however, be used in a number of ways. Normally, decorators complement the rich visual and behavioral changes by applying templates. In addition to overriding and enhancing the way existing elements are presented, the programmers also have option to use CSS to customize the decorators. Thus, each user can define his own decorator simply by using a markup and a scripting language.

3) Custom Elements
The custom elements can be defined as advanced DOM elements that can be defined by programmers. However, the custom elements, unlike decorators, are both ephemeral and stateless. So the programmers can use custom elements to encapsulate state, along with providing script interfaces. However, each author must understand some of the important differences between custom elements and decorators. A custom element can be defined through the < element > tag.

4) Shadow DOM
Most web developers use iframes to ensure that the user experience is not affected negatively due to HTML and CSS. Despite being useful, iframes cannot be used for building complex and large internet applications. As an innovative web component, Shadow DOM enables programmers to avail the features and advantages of iframes including style and markup encapsulation. The developers can further use Shadow DOM to strictly control the interaction between content and styles. The programmers can crate Shadow DOM simply by selecting an element, and then invoking its createShadowRoot method. The action will return a document fragment that can be filled with desired content.

5) Imports
Both custom elements and decorators can also be loaded from external sources. The < link > tag is used to define if the custom element or decorator will be loaded from external sources, along with the URL of the external file. The user agent can further interpret the decorators and custom elements. But the import property of the < link > tag will help the scrip in accessing the DOM. Further, programmers are required to use the CORs attribute to describe if the definitions are designed to run across multiple websites and internet applications.

The programmers can use web components to easily optimize the application’s look, feel, performance and security. The JavaScript component will help them in improving the website’s appearance, whereas other components will enable the application to interact with server smoothly. At the same time, the programmers can use plug in components to provide comprehensive security to the application by blocking unwanted traffic.

Top 5 Web technologies which can wow you

The last few years saw the triumph of HTML5, the gradual maturity attained by CSS3, the launch of Rails 3.0, as well as the extensive popularity of @font-face selector (which is in fact a component of CSS3), amongst different other technologies. In other words, web technologies have become increasingly popular and a lot of developments have taken place in this field around the last decade, a phenomenon that is still going on. Here we bring to you the top 5 web technologies you can bank on in the years to come. These technologies have in fact proved themselves to be trendsetters, having a notable impact on development of applications and websites.

• jQuery Mobile: JQuery is considered identical to JavaScript largely due to its ease of use, extensibility and robust project leadership features. Aiming to be an effective web framework for Smartphones and tablets, optimized for the touch screen aspect, jQuery Mobile is amongst the most popular projects, and is expected to carry forward the concept of cross device, cross platform web development to the next step. As an increasing number of developers are inclining towards HTML5 for creating apps, a strong JavaScript framework for the mobile becomes an enticing solution. In fact, jQuery has the potential to turn into the most effective mobile JavaScript framework.

• Web Browsers with Hardware Acceleration Capabilities: IE9 (Internet Explorer 9) is tremendously swift as it makes use of hardware acceleration and DirectX 10 technologies, which has the potential to increase the capabilities and speed of the browser to a great extent. The IE9 platform provides enhanced support to the native audio and video capabilities of HTML5 development. Microsoft has brilliantly crafted this browser version to bank on the most recent GPU chips and multicore processors bringing in the latest hardware.

• Server Side JavaScript and Node.js: Node.js is in fact a toolkit which enables the composition of event driven servers within JavaScript. This implies that users do not need to wait for sluggish I/O operations to get over before starting with other operations. In case of Node.js everything happens in the server side JavaScript. This is very significant for things which call for high speed, such as real-time web applications, file uploading, streaming, web crawlers and so on. Node.js expectedly marks a beginning of an extensive inclination for server side JavaScript.

• Synchronized Clickstream Sharing: There are a number of ways to share information or other stuff that you are coming across in the internet. There has been a huge explosion of social media sites and other publishing systems available online, all the more due to the mass incorporation of share buttons coupled with the continuous acceptance of desktop clients, bookmarklets and widgets, which all turned sharing into a very convenient task. Synchronized Clickstream sharing is most likely to become the next step, so far as sharing personal online experience is concerned.

• NoSQL Databases: NoSQL is in fact a very casually defined term that describes database engines which usually do not operate according to the conventional relational database architecture that is largely being used. No SQL databases are considered as alternative databases, and some of the notable ones in this group include Apache Cassandra, Amazon’s Dynamo, Google’s Big Table, CouchDB, MongoDB, Riak and Voldemort. NoSQL databases can effectively handle big data, which is a significant benefit keeping in mind the increasing volumes of data that businesses need to store. Moreover, NoSQL databases are very economical as they make use of groups of low-cost commodity servers for handling the ever-increasing transaction and data volumes. The flexible data models make room for convenient change management.

There is probably no culmination point for the developments taking place in web technologies. As innovative and original technologies are crowding the marketplace on a regular basis, more and more interesting technologies are expected to woo users with their exceptional features.
