eslint-plugin-wc

ESLint plugin enforcing best practices for Web Components, compatible with custom elements and libraries like LitElement. Current stable version 3.1.0, maintained actively. Requires ESLint >=8.40.0 and ships TypeScript types. Key differentiator: dedicated Web Components lint rules covering lifecycle callbacks, naming conventions, and shadow DOM correctness. ESM-only since v3.0.0; provides both legacy .eslintrc and flat config support.
