CLI to convert JavaScript files fromCommonJS toES6 / ES2015 modules format. The process isn't foolproof, but it can usually get you ~95% of the way there.

This tool usesjscodeshift to run5to6-codemod andjs-codemod under the hood. It attempts to convertrequire() andmodule.exports /exports toimport andexport.

npm i -g cjs-to-es6

cjs-to-es6 [ --verbose ] files/directories...

All files are modified in-place. You may want to review & rename them to the.mjs extension, if usingNode 14 or later. Un-converted files should use the.cjs extension.

Examples:

cjs-to-es6 index.js             # convert a single filecjs-to-es6 lib/                 # convert all files in a directory & its subdirectories (.js & .cjs)cjs-to-es6 foo.js bar.js lib/   # convert many files/directories
