esm-config

esm-config is a utility (v1.1.0) that transforms ES module configuration files to CommonJS using Rollup. It allows projects to use import/export syntax in config files (e.g., rollup.config.js, webpack.config.js) without Node.js native ESM support. The package has no release cadence; it's a small library that relies on a modified version of Rollup's internal loadConfigFile function. Compared to alternatives like @babel/register or esm, it focuses specifically on config loading and integrates Rollup's bundling.
