Lightning Web Components (LWC) Explained
LWC replaced the proprietary Aura framework as Salesforce's recommended front-end technology. Because it leverages standard browser APIs instead of a custom rendering engine, LWC components are lighter, faster, and easier for developers who already know modern JavaScript. Each component is a bundle of an HTML template, a JavaScript class, optional CSS, and a metadata XML file that controls where the component can be placed.
LWC components communicate through events, public properties, and the Lightning Message Service for cross-component messaging. They can call Apex imperatively or via wire adapters, interact with Lightning Data Service for CRUD without Apex, and be distributed on AppExchange. The framework supports Jest unit testing out of the box. Clientell AI can scaffold LWC components from natural language descriptions and deploy them directly to your org with the required metadata configuration.
