To train myself i'm currently creating a social media with react and firebase and i'm getting this error i can't resolve despise searching for answer here :
Uncaught Error: Objects are not valid as a React child (found: object with keys {message, user}). If you meant to render a collection of children, use an array instead.
To be clear, a "mood" can be viewed such as a facebook or status or an instagram post.
here's my code :
Firebase.js
import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';
const firebaseConfig = {
apiKey: "***************************",
authDomain: "*******.firebaseapp.com",
projectId: "********",
storageBucket: "**************",
messagingSenderId: "**************",
appId: "*****************************************"
};
const firebaseApp = firebase.initializeApp(firebaseConfig);
const db = firebaseApp.firestore();
const auth = firebase.auth();
export { auth, db };
Home.js
import React, { useState, useEffect } from 'react'
import Header from '../shared/header/Header'
import Mood from '../shared/mood/Mood';
import './Home.css'
import { doc, onSnapshot } from "firebase/firestore";
import { db } from '../../services/firebase';
function Home() {
const [moods, setMoods] = useState([]);
useEffect(() => {
db.collection("mood").onSnapshot((querySnapshot) =>
setMoods(
querySnapshot.docs.map((doc) => ({
id: doc.id,
data: doc.data()
}))
));
console.log(moods);
}, []);
return (
<div className='home'>
<Header />
<div className='feed'>
{moods.map(({id, data: {message, user}}) => (
<Mood
key={id}
message={message}
user={user}
/>
))}
</div>
</div>
)
}
export default Home
Mood.js
import React from 'react'
import './Mood.css'
function Mood(id, message, user) {
return (
<div className='mood'>
<h4>{id}</h4>
<h5>{user}</h5>
<p>{message}</p>
</div>
)
}
export default Mood
and don't hesitate to point out my react practice if you feel like it :)
thanks in advance guys!
CodePudding user response:
You just need to destructure the props in Mood component like this, and also you need to add another prop id={id} in home component
function Mood({id, message, user}) {
return (
<div className='mood'>
<h4>{id}</h4>
<h5>{user}</h5>
<p>{message}</p>
</div>
)
}
and another thing i can see is bad is in Home return statement when you are destructuring, do this instead {id, {message, user}}
