Lightning Web Component Preview in IDE VS CODE Using Lightning Preview #Salesforce #LWC #VSCODE
Summary
Lightning Preview lets Salesforce developers instantly preview and test Lightning Web Components (LWC) directly inside VS Code, without deploying to an org. It accelerates development by providing live rendering and auto-refresh of LWCs, supports styling with SLDS, and enables mocking data for front-end-only components. This streamlines the LWC build/test loop, saving time usually spent on org deployments and improving developer productivity. After setting up the Salesforce Extension Pack and Lightning Local Dev, developers can right-click LWCs in VS Code and preview changes in real time.
