LWC Online Editor Extension

The tool provides a browser-based editor to draft, validate, and preview Lightning Web Components (LWCs). It targets developers, admins, and QA teams needing rapid prototyping and consistency across projects, enabling iteration cycles, syntax checks, and mock data testing without installing Salesforce DX locally.
The core logic analyzes LWC syntax, resolves inter-module dependencies, and simulates data via a mock runtime to test component behavior in isolation. It offers a DX-ready export path and version-aware templates, ensuring compatibility with selected LWC releases.
Users can prototype patterns such as child-parent composition and wire adapters, then export a package suitable for DX workflows or direct integration tests. This yields consistent results across environments and reduces boilerplate setup.
The tool’s differentiators are LWC-specific semantics, an integrated data-mock layer, and ready-to-use templates for common LWCs, enabling faster iteration and safer experimentation. Target users span frontend developers, Salesforce admins, and QA engineers who need repeatable workflows and early validation of UI logic.
