eslint Parsing error: Unexpected token function with async

Answer 1

I was getting this error also, I added the following to my eslintrc:

{
  "env": {
    "node": true,
    "es6": true
  },

  "parserOptions": {
    "ecmaVersion": 8
  }
}

It's an error regarding func-style. By default it uses type expression, and the correct way to represent functions using this as expression is:

const get = async get(req, res) {
  const user = await service.get();
  console.log("From db",user.username);
  res.send('ok');
};

Check the docs for further examples, https://eslint.org/docs/rules/func-style

UPDATE: Forgot to see you have added error, what you were doing was right,

const get = async function get(req, res) {
  const user = await service.get();
  console.log("From db",user.username);
  res.send('ok');
};

Just remove func-style from eslint.

If you are new in the project I recommend just to go back with promises :)

function openTabs(array) {
    return new Promise((resolve, reject) => {
        //... your code
    });
}

In my case it got fixed when I just changed from:

"parserOptions": { "ecmaVersion": 8 }

to

"parserOptions": { "ecmaVersion": 2018 }
