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.

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.
