eslint-import-resolver-node is an ESLint resolver that uses Node's module resolution algorithm. It allows ESLint to correctly identify and validate imports when using non-standard Node.js module structures or custom configurations. This resolver supports features like resolving import paths relative to node_modules, respecting package.json configurations for module entry points and aliases, and following symlinks during resolution. Integrating this resolver prevents false-positive import errors in ESLint and ensures accurate code analysis.
