support async/await function

[lednhatkhanh]

Hello, when I try to change my function using async/await like this:

const login = async (req, res, next) => {
  const user = await User.findOne({ email: req.body.email });

  if (!user || !bcrypt.compareSync(req.body.password, user.password)) {
    const err = new APIError('Authentication error', httpStatus.UNAUTHORIZED, true);
    return next(err);
  }

  const token = jwt.sign({
    email: user.email
  }, config.jwtSecret);
  return res.json({
    token
  });
};

I got this error when running yarn start

  var _ref = _asyncToGenerator(regeneratorRuntime.mark(function _callee(req, res, next) {

Any ideas on how to fix this or supporting this? Thank you, I'm not so used to these config things.

I can confirm @fcpauldiaz solution!

@osahner thank you but it doesn't work

@lednhatkhanh install the babel-polyfill and import it before all other modules in index.js

import polyfill from 'babel-polyfill'; // eslint-disable-line
