VistasHow can I dynamically render all user post images with React?
I am trying to render in all user posts images in my web application with React in my Discover component. How can I go about doing this? This is how the objects look like in JSON:
This is what I have currently in my discover component.
Discover.jsx:
import React, {useState, useEffect} from 'react';
import {Link} from 'react-router-dom';
import {useSelector} from 'react-redux';
import UserPostsService from '../../services/user-post.service';
import './styles/Discover.css';
const Discover = () => {
const [content, setContent] = useState('');
const [photoURL, setPhotoURL] = useState('/images/user-solid.jpeg');
useEffect(() => {
UserPostsService.getAllPosts().then(
(response) => {
if (response.data.postImage)
setPhotoURL(response.data.post_img_complete);
},
(error) => {
const _content =
(error.response &&
error.response.data &&
error.response.data.message) ||
error.message ||
error.toString();
setContent(_content);
}
);
}, []);
return (
<div className='page'>
<div className='user-post'>
<img src={photoURL} alt='User-Post' className='post'></img>
</div>
</div>
);
};
export default Discover;I need to render each post_img_complete somehow, but I am not sure how to go about this. Any help is appreciated, thank you!

Since you want to render all posts, you need to store the data array in your state. Then you can map over the state to render all posts.
I create a state named posts. I get the data array from response and store it in posts state. Now i map over the posts state and render each post image.
import React, {useState, useEffect} from 'react';
import {Link} from 'react-router-dom';
import {useSelector} from 'react-redux';
import UserPostsService from '../../services/user-post.service';
import './styles/Discover.css';
const Discover = () => {
const [content, setContent] = useState('');
// const [photoURL, setPhotoURL] = useState('/images/user-solid.jpeg');
const [posts, setPosts]=useState([]);
useEffect(() => {
UserPostsService.getAllPosts().then(
(response) => {
if (response.data) setPosts(response.data)
},
(error) => {
const _content =
(error.response &&
error.response.data &&
error.response.data.message) ||
error.message ||
error.toString();
setContent(_content);
}
);
}, []);
return (
<div className='page'>
{posts.map((post)=>(
<div className='user-post'>
<img src={post.post_img_complete} alt='User-Post' className='post'/>
</div>
))}
</div>
);
};
export default Discover;
