I'm fetching dynamic data from my nodejs to reactjs but I get an error saying "POST IS NOT DEFINED" - node.js

Question

I have made entries in my mongodb database using node now I'm trying to fetch that data from backend to react front-end the 3rd party app used for cross-platform in node are cors and for react is axios(in script I have added "proxy":"http://localhost:5000"(5000 is my backend port)
Here is my code for NovelCard.js
import React, { Component } from 'react';
import { Container } from 'react-bootstrap';
import Card from 'react-bootstrap/Card';
import axios from 'axios';
const createSet = (post) => {
<Card style={{ width: '18rem' }}>
<Card.Img variant="top" src="holder.js/100px180" />
<Card.Body>
<Card.Title>{post.name}</Card.Title>
<Card.Subtitle className="mb-2 text-muted">{post.author}</Card.Subtitle>
<Card.Text>{post.synopsis}</Card.Text>
</Card.Body>
</Card>;
};
class Latest extends Component {
state = {
name: '',
author: '',
synopsis: '',
post: [],
};
componentDidMount = () => {
this.getData();
};
getData = () => {
axios
.get('http://localhost:5000/novels/')
.then((res) => {
const data = res.data;
this.setState({ post: data });
console.log('data recived');
})
.catch(() => {
alert('error');
});
};
render() {
console.log('state', this.state);
return <Container>{post.map(createSet)}</Container>;
}
}
export default Latest;
I'm getting error saying ***
src\components\home\Latest\NovelCard.js Line 45:24: 'post' is not
defined no-undef

Your post variable is available within you state. You need to do something like this within your render function.
render() {
console.log('state', this.state);
return <Container>{this.state.post.map(createSet)}</Container>;
}
Or you can do like this as well.
render() {
const { post } = this.state;
console.log('state', this.state);
return <Container>{post.map(createSet)}</Container>;
}
