Trying to fetch from API but getting [object Promise] instead

Time:05-08

I'm trying to make a website that fetches a random 10 lines from a poem and then outputs them in the HTML file but instead of getting the .json data I'm getting [object Promise]. Can someone help me out?

Here's my code:

JS:

let url = 'https://poetrydb.org/random,linecount/1;10/title,author,lines.json'
const button = document.getElementById('button')
const body = document.getElementById('poem')

async function requestPoem(url) {
    await fetch(url)
    .then((response)=>{
        let data = response.json()
        return data
    })
}

button.onclick = ()=>{
    body.innerHTML = requestPoem(url)
}

HTML:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <script defer src="scripts/main.js"></script>
    <title>poem request</title>
</head>
<body>
    <p id="poem"></p>
    <button id="button">request poem</button>
</body>
</html>

requestPoem is an async function, so it can only ever return a promise. You can't avoid the promise, but you can use it, either by calling .then on it, or by putting your code in an async function and awaiting the result. Also, your current requestPoem function has no return statement, so it will need one to define what the promise resolves to.

async function requestPoem(url) {
  const response = await fetch(url);
  return response.json();
}

button.onclick = async () => {
  body.innerHTML = await requestPoem(url);
}

Turns out the mistake in the code was that the API was returning an array of objects instead of a single object. Because of this I first had to return data[0] and get the object's properties from there.
