Question

Getting a error message saying Parsing error: Can not use keyword \'await\' outside an async function from below code for Redux action.

What is the proper w

Answer 1

You need to have async keyword for the inner function

export function getData() {
  return async (dispatch) => {
    try {
      const data = await API.graphql(graphqlOperation(query))
      dispatch({ type: "DATA_AVAILABLE", data: data.data.listData.items });
    } catch(err) {
      console.log('error: ', err)
    }
  }
}

Answer 2

You can pull your await function out of your return function as well and pass dispatch as a param to getData function.

export async function getData(dispatch) {
  const data = await API.graphql(graphqlOperation(query))
  dispatch({ type: "DATA_AVAILABLE", data: data.data.listData.items });
}

then you call it:

var dispatchFunc = function (params) {console.log(params);}
getData(dispatchFunc).then(function() {}).catch(function(err) { ... })
