Salesforce Lightning is a component-based framework for app development from Salesforce.com that is designed to simplify processes for business users

Salesforce has recently released the Lightning Web Components (LWC) that is a new programming model for building Lightning components. This is a tool that allows developers to code components in the Lightning Platform.

This is an updated Framework for building Salesforce Lightning Apps. Salesforce introduced Lightning Web Components as a newer and faster way of programming applications on the Salesforce Lightning Platform. This is based on the ES6+ standards and thus employs modern JavaScript breakthroughs like web components, custom elements, Shadow DOM (Document Object Model), etc.
Characteristics:

  • It leverages custom elements, templates, shadow DOM (Document Object Model), decorators, modules, and other new language constructs available in ECMAScript 7 and beyond.
  • Lightning Web Components provides a layer of specialized Salesforce services on top of the core stack, including:
    1. Base Lightning Components: This includes a set of over 70 UI components all built as custom elements.
    2. Lightning Data Service: It provides declarative access to Salesforce data and metadata, data caching, and data synchronization.
    3. User Interface API: This underlying service that makes Base Lightning Components and the Lightning Data Service metadata aware, leading to substantial productivity gains.
  • It also combines Web Components programming model with the Salesforce metadata and services thus providing an unmatched level of performance and productivity.

 Advantages:

  • With Lightning Web Components, it has been given to developers a standards-driven JavaScript model for building enterprise apps on Lightning.
  • It is an inclusive programming model that will work for all front-end JavaScript developers.
  • It supports JavaScript web components because more than 95 percent of websites use JavaScript, and an estimated 7.04 million developers worldwide tap JavaScript to program tools and apps, according to recent report.
  • Enhanced Performance– Lightning web components will run on the browser without any complex abstractions thus providing better performance to end users.
  • Ease of Use– Once developed, the admins can deploy Lightning Web Components with clicks to the applications.
  • Standardized– Lightning Web Components is built on ES6+ which exposed developers with the modern and advanced JavaScript features.
  • Compliant to web standards.
  • Lightweight
  • Memory efficient
  • Fast
  • Easier to learn and Transferable knowledge. 

What will happen to existing Lightning Components?

Developers can continue to build lightning components using Aura framework with parallel to Lightning web component but for future development Salesforce will recommend to use Lightning Web Components.
Availability
Lightning Web Components will be available for the users by February 2019 in Enterprise, Unlimited, Performance or Developer Edition org.
Conclusion
Lightning Web Components give developers more choice to build the applications on the Salesforce Lightning platform with the modern offerings of the web development with better performance for the end users.
