The issue is that the original axiosTest() function isn't returning the promise. Here's an extended explanation for clarity:
function axiosTest() {
// create a promise for the axios request
const promise = axios.get(url)
// using .then, create a new promise which extracts the data
const dataPromise = promise.then((response) => response.data)
// return it
return dataPromise
}
// now we can use that data from the outside!
axiosTest()
.then(data => {
response.json({ message: 'Request received!', data })
})
.catch(err => console.log(err))
The function can be written more succinctly:
function axiosTest() {
return axios.get(url).then(response => response.data)
}
Or with async/await:
async function axiosTest() {
const response = await axios.get(url)
return response.data
}
