eslint-plugin-check-file

ESLint plugin for enforcing consistent naming conventions for files and folders. Current stable version is 3.3.1, requiring Node >=18 and ESLint >=9 with flat config. Provides five rules: no-index, filename-blocklist, folder-match-with-fex, filename-naming-convention (supports built-in cases like PASCAL_CASE, CAMEL_CASE, NEXT_JS_PAGE_ROUTER_FILENAME_CASE), and folder-naming-convention. Unlike generic naming tools, it uses glob patterns to target specific file paths and supports linting non-JS/TS files via a dedicated processor. Ships TypeScript definitions.
