Better performance, user experience, and security are the key parameters to keep in mind when pursuing innovation in tech.
Along these lines, the most exciting development in the last few years was the release of Lightning Web Components by Salesforce which is the most used and talked about.
It’s a stand-out innovation that delivers on each of the above-mentioned parameters successfully.
Lightning Web Components is essentially a programming model that enables you to use custom templates, elements, modules, shadow DOM, and decorators.
It also provides a set of specialized services that are an extension of the existing cutting-edge web technologies and core stack. These services include Lightning Data Service, User Interface API, and base lightning components.
What are Lightning Web Components?
To understand Lightning Web Components in a better way, it is first important to know the tech it is built on. The concept of ‘components’ has existed in the webspace for quite some time now.
The idea behind it is to split the components of the User Interface (UI) into smaller chunks. These chunks are meant to be self-contained and reusable.
Now that you understand components, you might ask: What is a web component?
Web Components are primarily a set of standards for different specifications.
These specifications mainly include:
These are the user-defined HTML templates that are rendered when they are called upon. This template is embodied in the HTML Living Standard specification.
This specification focuses on the reuse and inclusion of JS documents in a standard-based, modular, and performant way.
Lightning Web Components are built on top of these specifications using standardization as a tool to implement a new variety of lightweight web frameworks. These frameworks bring specialized functionality to the platform, rather than simply plugging gaps within it.
Here are some use-cases related to Lightning Web Components that could help you understand its capabilities more closely.
1. Adding Actionability on the Dashboards
Using LWC, you can implement things like Lighting record forms, Lightning data tables, or any custom functionalities for enabling record-based actions on a dashboard.
2. Model Analytics and Next Best Action
LWC allows you to create custom ‘next best actions’ (for guided processes) that can be used directly inside the analytics. LWC can also help to manage many customized what-if scenarios.
3. Custom Charts and Visualization
4. Interacting with third-party system data
LWC allows the use of ‘iframes’ to show third-party systems in Salesforce. It helps to display analytics along with dashboards.
Consider a scenario where you need to display a dashboard housed on a third-party service or an application that needs to be used with the dashboard to initiate actions.
An example of this is to display Tableau dashboards.
Reasons for you to migrate to Lightning Web Components
As you’ve just seen, Lightning Web Components have emerged as the new lightweight framework with various advantages over the existing Aura web components.
We’ve listed some major reasons businesses are (and should) consider migrating to Lightning Web Components:
Easy to use:
Native web standards are used to develop this framework which are present in the browser and there is no additional abstraction layer, like in frameworks such as Aura.
As the name ‘lightning’ suggests, this framework loads the components a lot faster than its predecessors.
An abstraction layer is absent in this framework which makes it faster to render than components of Aura which leads to improved performance.
LWC allows you to write components that can be seamlessly reused in other components. This is possible as there are no UI limitations here.
The framework supports built-in browser security features which help to reduce the need for customization. This helps to facilitate a more out-of-the-box usage.
Lightning Web Components can successfully stand on the parameters of browser compatibility, better testing, and security, considering the way it used Script, CSS, and DOM Isolation.
Easy to Learn:
Developers do not need to learn any additional framework for working with Lightning Web Components, thus making the transition smooth.
Everything we discussed should make it clear that it’s time to leave behind the struggle you’re facing with Aura components and make the transition to Lightning Web Components for a smoother workflow.
