Trying to pass props and state to a child component - reactjs

Question

I have a parent functional component and i need to pass props and state to a child functional component, i have managed to pass only one of theme (props or state), the code below displays the fetched data, firstly i've been using const Footer = ({name, adresse, phone}) => {} and then i've replaced it with const Footer = (props) => {} i thought i can pass them this way!!
{props.colorScheme} is accessible in App.js but not in Footer component, should i use context API to pass the props?
FYI, here is my index.js :
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
const colorScheme = root_el.getAttribute("color-scheme");
ReactDOM.render(
<App customBackground={customBackground} colorScheme={colorScheme} />,
root_el
);
My App component
import React, {useEffect, useState, Suspense, lazy } from 'react';
import axios from 'axios';
import Footer from "./components/Footer";
const App = (props) => {
const [infos, setInfos] = useState({});
useEffect( () => {
loadData();
}, []);
const loadData = () => {
axios.get(`https://api`)
.then((res) => {
console.log(res.data);
const infs = setInfos(res.data);
});
}
return (
<div>
<Footer name={infos.name} adresse={infos.adresse} phone= {infos.phone}
</div>
)
};
export default App;
My child component :
import React from 'react';
const Footer = (props) => {
const {name, adresse, phone} = props;
return (
<div>
<h3>{props.colorScheme}</h3>
<span>{name}<span>
<span>{adresse}<span>
<span>{phone}<span>
</div>
)
}
export default Footer;

You can continue to pass the props down to the footer component or you can, as you point out, use a context. Passing the colorScheme via the props is shown below.
Note: Your code was displaying the colorScheme as an h3 in the Footer and I left that as is.
Updated App Component:
import React, {useEffect, useState, Suspense, lazy } from 'react';
import axios from 'axios';
import Footer from "./components/Footer";
const App = (props) => {
const [infos, setInfos] = useState({});
const { colorScheme } = props;
useEffect( () => {
loadData();
}, []);
const loadData = () => {
axios.get(`https://api`)
.then((res) => {
console.log(res.data);
const infs = setInfos(res.data);
});
}
// Footer tag below was missing the tag's closing
// Added colorScheme prop
return (
<div>
<Footer
colorScheme={colorScheme}
name={infos.name}
adresse={infos.adresse}
phone= {infos.phone}/>
</div>
)
};
export default App;
Updated Footer
import React from 'react';
const Footer = (props) => {
const {name, adresse, phone, colorScheme} = props;
return (
<div>
<h3>{colorScheme}</h3>
<span>{name}<span>
<span>{adresse}<span>
<span>{phone}<span>
</div>
)
}
export default Footer;
You can also create a new Context using createContext and useContext so that you can have a single way for all your components to access it. You won't have to pass the color scheme through props. You may want to do both so that you have a global set of default colors and then a prop that lets you override them.
