ERROR from UglifyJs SyntaxError: Unexpected token: name (SocketProvider)

Hi, I'm trying to integrate this package into my React app.

I'm using webpack and I get this error when I build:

ERROR in my-app.0.0.1.js from UglifyJs
SyntaxError: Unexpected token: name (SocketProvider)

Do you have any idea of the reason?

Gracias

can you share a basic code to replicate the error?

I met the same problem, here is the error info:

ERROR in main.min.js from UglifyJs
SyntaxError: Unexpected token: name (SocketProvider) [../~/socket.io-react/build/SocketProvider.js:21,0]

And this is the relevant code from line 21 of SocketProvider.js:

let SocketProvider = function (_Component) {
  _inherits(SocketProvider, _Component);

  function SocketProvider() {
    _classCallCheck(this, SocketProvider);

    return _possibleConstructorReturn(this, Object.getPrototypeOf(SocketProvider).apply(this, arguments));
  }

  _createClass(SocketProvider, [{
    key: 'getChildContext',
    value: function getChildContext() {
      return {
        socket: this.props.socket
      };
    }
  }, {
    key: 'render',
    value: function render() {
      return this.props.children;
    }
  }]);

  return SocketProvider;
}(_react.Component);

I'm not quite sure about the reason, is it because of let?

I've tried to change let into var, then the error disappeared.

It looks no problem on SocketProvider, but I'm just afraid if it would go down because of my replace...

Anyway, I think the error is still from keyword let, I wish it can be fixed. Thanks!

I just published the v1.1.2 with the let replaced with a var, let me know if the error continue :)
