I am trying to export this class in node.js:

export class className {
  static method1(param1) {
    // do something
  }

  static method2(param1, param2) {
    // do something
  }
}

But it's getting me the following errors in terminal:

complete_path.....\node_modules@babel\runtime\helpers\esm\classCallCheck.js:1 [2] (function (exports, require, module, __filename, __dirname) { export default function _classCallCheck(instance, Constructor) { [2]

Use module.exports and not export

module.exports = class className {

 static method1(param1) {
     // do something
 }


 static method2(param1, param2) {
     // do something
 }

}

The export keyword is not supported by Node.js yet. You have to use the exports or module.exports ones.

In your case you should use the module.exports:

module.exports = class className {
  static method1(param1) {
    // do something
  }

  static method2(param1, param2) {
    // do something
  }
}

For more information about the difference between the exports and module.exports I suggest you this post.
