ESLint Config Enact

5.1.0 verified Sat Apr 25 auth: no javascript

ESLint configuration package for Enact applications, currently at version 5.1.0. This package provides a shareable ESLint flat config with Enact team's standard and strict rule sets. It targets Node ^20.12.0 || ^22.0.0 || >=24.0.0 and requires ESLint ^9.20.0. Key differentiators: opinionated rules for Enact framework, includes React, React Hooks, Babel, Jest, and Enact-specific plugins. Recent major updates: migrated to ESLint v9 flat config (v5.0.0-alpha.5), removed deprecated prop-types rule (v5.0.0-beta.1), and disabled React compiler-related rules (v5.0.3). Release cadence is irregular, with breaking changes in major versions.
