Steps for Transferring a Const from One File to Another

I am facing an issue with passing the const clouds variable from one file to another.

There seems to be something I am overlooking and I have been looking at this for too long - I really appreciate your help!

Source: getAVWXData.js

import axios from 'axios'

export function getAVWXData() {

  axios.get(
    https://some_url
  )
  .then((response) => {
    const v      = this     
    const res    = response.data
    const clouds = res['Cloud-List'][0.0][1];
    console.log('Give me Clouds! ' + clouds) // <-- This works
  })
}

Destination:

import { getAVWXData } from './get-avwx-data'

getAVWXData()
console.log('Give me Clouds! ' + getAVWXData.clouds) // < Returns undefined!

Answer №1

In order to retrieve the Cloud data, you need to create a promise that returns a value:

import axios from 'axios'

export function fetchCloudData() {

  return axios.get(
    https://some_url
  )
  .then((response) => {
    const clouds = this     
    const responseData = response.data
    return responseData['Cloud-List'][0.0][1];
  })
}

Additionally, utilize the following code snippet to access and display the Cloud data:

import { fetchCloudData } from './fetch-cloud-data'

fetchCloudData().then((result) => {
  console.log('Cloud information: ' + result.result) // <- This should output the Cloud value
})

The issue at hand is that the function getAVWXData does not return any data, and the data you are attempting to access is nested within a resolved promise. To retrieve the value of clouds, you will need to follow this pattern:

import axios from 'axios'

export function fetchAVWXData() {

  return axios.get(
    https://some_url
  );
}

and

import { fetchAVWXData } from './fetch-avwx-data'

fetchAVWXData().then((response) => {
  console.log('Show me Clouds! ' + response.data.clouds)
});

It is crucial to wait for the promise to resolve before accessing the data in the response.
