Polymer Linter

Polymer Linter (v3.0.1) is a library for finding suspicious patterns and errors in web projects using Polymer custom elements. It is built on the Polymer Analyzer and provides AST-based linting with high-level feature queries. The linter is typically run via Polymer CLI or integrated into editors like VS Code. It offers rule collections (e.g., polymer-2-hybrid) and individual rules. Release cadence is low, as the project is in maintenance mode. Key differentiators: Polymer-specific linting rules (e.g., attribute checks, behaviors spelling) and tight integration with Polymer toolchain.
