Issue
I've built a random photo displaying feature in react.
the console says that the response is valid and it works,
but the page breaks when I return data
.
Where is the issue? Thanks in advance!
import React from 'react'
import { useEffect, useState } from 'react'
import axios from 'axios'
function RandomPhoto() {
const url = `https://api.unsplash.com/photos/random/?client_id=${process.env.REACT_APP_UNSPLASH_KEY}`
const [data, setData] = useState()
const getPhoto = () => {
axios.get(url)
.then(response => {
setData(response.data)
console.log(response.data) // <------- works
})
.catch(error => {
console.log(error)
})
}
useEffect(() => {
getPhoto()
},[])
console.log("XX" + data) // <---------- doesn't work, and following return() neither
return (
<div>
<img href={data.urls.regular} alt={data.alt_description}/>
<p>Photo by {data.username} {data.name} from {data.location} - found on unsplash</p>
</div>
)
}
export default RandomPhoto
Solution
I modified your code a bit, and it's working. I made it as an async function and changed the path of JSON object keys.
Please note the location data sometimes returns as null. So you have to render it conditionally.
import React from 'react';
import { useEffect, useState } from 'react';
import axios from 'axios';
const RandomPhoto = () => {
const url = `https://api.unsplash.com/photos/random/?client_id=${process.env.REACT_APP_UNSPLASH_KEY}`;
const [imageData, setImageData] = useState('');
const getPhoto = async () => {
await axios
.get(url)
.then((response) => {
setImageData(response.data);
})
.catch((error) => {
console.log(error);
});
};
useEffect(() => {
getPhoto();
}, []);
return (
<div>
<p>Hello</p>
<img src={imageData.urls?.regular} />
<p>
Photo by {imageData?.user?.username} {imageData?.user?.name} from{' '}
{imageData?.location?.country} - found on unsplash
</p>
</div>
);
};
export default RandomPhoto;
