LWC (Light Web Components) has become a popular programming technique for creating web components. It provides specialized services that build on existing cutting-edge web technologies. In technology, a better user experience is the essential criteria for pushing change and innovation. Likewise, LWC's performance remains unrivaled, giving its users a competitive advantage. It is compatible with the traditional Aura programming model; thus, the coexistence significantly boosts web standards. Let's take a closer look at Lighting Web Components to see how they work and why you should use them.
Light Web Components- Definition
Lighting Web Components works deploying the following methods-
- The Lightning Data Service gives you declarative access to Salesforce data and metadata, as well as data caching and synchronization.
- Base Lighting Components handles the collection of over 80 UI components that were created as bespoke elements.
- The User Interface API acts as a core service that enables metadata awareness in Base Lightning Components and the Lightning Data Service.
- The lightning framework is heavily event-driven, allowing for speedier software delivery to end-users.
- Lightning Component pages perform better than legacy pages.
- Components are adaptable and straightforward, resulting in a stable and quick framework.
LWC (Lightning Web Components) employs a variety of standards with various specifications.
- HTML templates: These are user-defined HTML templates that are only rendered when requested. The HTML Living Standard specification is the best representation of this template.
Evolution Of Lightning Web Components
Salesforce released the Lightning Web Component framework in 2014, based on the Aura programming framework. Because web standards made it difficult to create large-scale web applications, Aura introduced its component-driven program, allowing developers to build large-scale client applications.
This made skill transfers and ramp-ups extremely difficult. A Salesforce platform was introduced as an extension of web component standards that helps execute the same activities as the lightning component to increase flexibility and standardization.
Why Are Lightning Web Components Better Than Aura?
The uses of improved Lightning Web Components have surpassed the drawbacks of Aura in several ways. The most major welcomed outcome of this transformation as below-
- Standardized performance
Lightning Web Components is known for its outstanding performance. It has evolved as a robust programming model. LWC uses elements, shadow DOM, modules, templates, and other ECMAScript 7 language structures, among other things. By incorporating LWC into your company, you may improve your Salesforce lightning platform and push it to utilize web standards for UI development.
- Easy To Use
- Cross-browser compatibility
By deploying SLDS, apps provide users with a pleasurable experience (responsive design). Lightning Web Components are compatible with cutting-edge browser technologies such as CSS3, HTML5, and touch events.
- Allow Customisation
The Salesforce Lightning Design System (SLDS) allows business owners to customize the look and feel of the various components. As a result, you can personalize the elements as needed. In summary, business owners do not need to be concerned about responsiveness.
- Enhances Speed
Lightning Web Components allow teams to carry out their tasks faster with sophisticated components, working seamlessly with mobile and desktop devices. The Admin implementing the Lightning App Builder must drag and drop them on the necessary page using the generic component. The entire developmental efficiency boosts, along with parallel designing with elements.
- Reduce Errors
Another advantage of deploying LWC is avoiding lesser error occurrences and experiencing a two-way binding process. This justifies why forward-thinking businesses have been deploying Lightning Web Components lately into their respective frameworks.
How to Make the Transition from Aura To Lightning Web Components
Thing To Consider: Before you do that, keep in mind that the fundamentals of both models are highly different and not a simple line-by-line comparison.
Lightning Web Components are the way of the future in terms of lightning development. It defines an opportunity to rethink, rearrange, and streamline the procedure. Consider leveraging Lightning Web Components to utilize the improved native speed and browser compatibility if you're building new functionality.
LWC's developer guide will offer you all the tools and information you need to take the proper migration path towards lightning web components. It enables users to come up with generic features for a seamless performance.
