Automatic Node.js Version Selection Based on Project Configuration

Wallaby now automatically detects and selects the appropriate Node.js version for your project based on configuration files like .nvmrc, .node-version, package.json (engines.node field), and more. When multiple Node.js versions are installed on your system, Wallaby intelligently chooses the version that matches your project’s requirements using existing version managers (e.g. nvm, volta, fnm, asdf, etc.). This eliminates the need for manual configuration and ensures your tests run in the correct Node.js environment without any additional setup.
