Web Components – What and Why?
A web component helps to create encapsulated, reusable user interface elements for the web in a standardized way. Since the past couple of years, there has been up and down buzz around web components. Components for the web have been around for a long time, the idea of being able to write reusable and portable code is nothing new.
Popular examples include the jQuery plugins and Angular directives. It’s been said that web components possess the potential to will change the way we build for the web. But what makes these components so important?
In the past, you only had a specific set of technologies with a very hard upgrade path — which might have even lead to an application re-write. As web components are interoperable, they can move beyond frameworks and be used in multiple projects of different technology stacks. Thus, they can be considered platform independent which makes them universal in a way. This is because components are built on nothing more than web standards that will work across all ecosystems.
A component should be totally different from the main application. This is useful as it increases reusability, testability, and reliability. Because the component is only responsible for its internals, it doesn’t concern itself with the state of the application, except its own.
Both the component author and user can upgrade the component without the fear of affecting the rest of the application that uses the component.
Productivity and Associativity
Using pre-built components and iterating on top of them lets us develop faster and makes the work much more productive. Web components also enable developers to write applications in a more modular way by breaking the applications down into smaller logical chunks with reusable functionality. Moreover, by using and extending existing browser elements, the default browser accessibility comes with these components that you are using.
Web Component’s Future – Conclusion
Without a doubt, the Web Components specification is going to play a large role in the development of front-end web applications in the future.
