UnRS Resolver is a high-performance, Rust-ported module resolution library for Node.js environments, currently at version 1.11.1. It provides a robust implementation of both ECMAScript Module (ESM) and CommonJS resolution algorithms, closely aligning with webpack's enhanced-resolve. Key differentiators include built-in `tsconfig-paths-webpack-plugin` support for handling `tsconfig.extends`, `compilerOptions.paths`, and `references`, along with specific enhancements for Yarn Plug'n'Play (PnP) resolution. The library also features an in-memory file system via its `FileSystem` trait and `tracing` instrumentation. It addresses known resolution issues encountered by tools like `eslint-plugin-import-x` and `eslint-import-resolver-typescript`, ensuring greater compatibility and correctness in complex monorepos and build setups. The project maintains an active release cadence, regularly syncing with upstream `oxc-resolver` for improvements and bug fixes.
