As you embark on building your own Lightning Web Components (LWC), establishing the right development toolkit is a crucial first step. While technically any text editor can be used, a specialized set of tools significantly enhances productivity and success, especially for experienced Salesforce developers or newcomers to the platform. This guide will walk you through installing and configuring the essential tools needed to create and manage LWC projects. Learn about LWC.
