Unused Exports

Tool for identifying and reporting unused exports found in ECMAScript/JavaScript code.

You may think of it as ESLint no-unused-vars rule, but for the whole project scope.

Tool uses Babel parser to parse source code. You can provide custom parser options using config file.

Instalation

npm install -g js-unused-exports

 E.g.: js-unused-exports --config "unused-exports-config.json"

  -c, --config [path]  path to the JSON config file
  -o --out-dir [path]  path to print scan results as JSON
  -f, --fix            automatically remove "export" directive where possible
