eslint-plugin-filenames

An ESLint plugin that enforces consistent filenames for JavaScript files. Current stable version is 1.3.2 (last updated 2019). It provides three rules: `match-regex` for custom regex patterns, `match-exported` to align filename with the default export, and `no-index` to disallow `index.js` files. The plugin only lints `.js` and `.jsx` files that ESLint processes. Unlike alternatives like `eslint-plugin-filenames-simple` or `eslint-plugin-unicorn`'s filename rule, this one is lightweight and focused, but note it is not actively maintained.
