Node.JS module error - Is not a function when calling it from my index.js-CodePudding

I am trying to make use of a newly create Node.JS module but I am getting an error saying: "Is not a function".

lib/weather.mjs

My module's code is below:
// Gets the weather of a given location
import fetch from 'node-fetch';

var latLongAirports = [{
        "name": "Madrid",
        "iata": "MAD",
        "lat": 40.49565434242003,
        "long": -3.574541319609411,
    },{
        "name": "Los Angeles",
        "iata": "LAX",
        "lat": 33.93771087455066,
        "long": -118.4007447751959,
    },{
        "name": "Mexico City",
        "iata": "MEX",
        "lat": 19.437281814699613,
        "long": -99.06588831304731,}]

export default function getTemperature (iata){
    async (dispatch) =>{
        let data = latLongAirports.find(el => el.iata === iata);
        var url = "http://www.7timer.info/bin/api.pl?lon="   data.long   "&lat="   data.lat   "&product=astro&output=json"
        const response = await fetch(url);
        const myJson = await response.json();
        return myJson.dataseries[0].temp2m
    }
}

And this is how I am trying to use it from my main.js

import weather from './lib/weather.mjs'
var temperature = weather.getTemperature("MEX")

What am I doing wrong here? How should I declare and use self written modules like those?

Thank you!

CodePudding user response：

weather.mjs is exporting the function. So what you get in main.js is the actual function.

In your main.js you should call the exported method like

import getTemperature from './lib/weather.mjs'
var temperature = getTemperature("MEX")
