NETXJS: transfer data from page to component with hooks

Hey how are you? i'm using nextjs / styled components and i would like to change a string via props. I made a layout component with a main and it has an props to make it dinamic per page
Page 'prueba.js'
import React from 'react';
import Layout from '../components/Layout/Layout';
const prueba = () => {
const setNewBackground = 'green';
console.log(setNewBackground)
return (
<Layout setNewBackground={setNewBackground}>
<p>holaaaaa</p>
</Layout>
);
}
export default prueba;
Layout.js component
import React,{useState} from 'react';
import Main from './Main';
const Layout = props => {
const [background, setBackground] = useState('blue')
const setNewBackground = () => {
setBackground (background);
}
return (
<>
<Main newBackground={background}>
{props.children}
</Main>
</>
);
}
export default Layout;
And Main.js component
import styled from '#emotion/styled';
const Main = styled.main`
background:${props => props.newBackground};
height:100vh;
width:100%;
`;
export default Main;
I check it in console but it shows me undefined. Wheres the error :(? thanks and have a good year!

You don't need to create a state for that. You can use only the color prop you passed to the Layout.
Prueba.js
import React from 'react';
import Layout from '../components/Layout/Layout';
const prueba = () => {
return (
<Layout backgroundColor='green'>
<p>holaaaaa</p>
</Layout>
);
}
export default prueba;
Layout.js
import React,{useState} from 'react';
import Main from './Main';
const Layout = ({ backgroundColor, chidlren }) => {
return (
<Main backgroundColor={backgroundColor}>
{children}
</Main>
);
}
export default Layout;
Main.js
import styled from '#emotion/styled';
const Main = styled.main`
background:${({ backgroundColor }) => backgroundColor || 'your default color'};
height:100vh;
width:100%;
`;
export default Main;

React Context api, I can't get to object from context

I started to learn React, I'm trying to retrieve data from api, the data is an object with the fields of base, date & rates, without any problem I can print and logout base & date but rates which is an object not.
console.log gives undefined, when trying to iterate is obviously that the object does not exist but in DevTools i can see normal data
Thank you for your help and greetings
Context:
export const ExchangeProvider = props => {
const [lastestExchanges, setLastestExchanges] = useState({})
const fetchLastestExchange = async () => {
try {
await fetch(`https://api.exchangeratesapi.io/latest`).then(data => data.json()).then(data => setLastestExchanges(data))
} catch (err) {
console.log(err)
}
}
useEffect(() => {
fetchLastestExchange()
}, [])
return (
<ExchangeContext.Provider value={[lastestExchanges, setLastestExchanges]}>
{props.children}
</ExchangeContext.Provider>
)
}
Usage:
import React, {useState, useContext} from "react";
import {ExchangeContext} from "../ExchangeContext";
function HomeView() {
const [lastestExchange, setLastestExchange] = useContext(ExchangeContext)
console.log(lastestExchange)
return (
<div className="container">
<p>{lastestExchange.base}</p>
<p>{lastestExchange.date}</p>
{/*<p>{lastestExchange.rates['PLN']}</p>*/}
<ul>
{/*{Object.keys(lastestExchange.rates).map(key => <li>{lastestExchange.rates[key]}</li>)}*/}
</ul>
</div>
)
}
export default HomeView
Provider usage:
import React from 'react';
import HomeView from "./Views/HomeView";
import {
BrowserRouter as Router,
Switch,
Route,
Link
} from "react-router-dom";
import {ExchangeProvider} from "./ExchangeContext";
function App() {
return (
<ExchangeProvider>
<div className="App container w-full flex h-full">
<Router>
<Switch>
<Route path="/">
<HomeView/>
</Route>
</Switch>
</Router>
</div>
</ExchangeProvider>
);
}
export default App;

You can use react context simpler like this :
// src/ThemeContext.js
import React from 'react';
const ThemeContext = React.createContext(null);
export default ThemeContext;
// src/ComponentA.js
import React from 'react';
import ThemeContext from './ThemeContext';
const A = () => (
<ThemeContext.Provider value="green">
<D />
</ThemeContext.Provider>
);
// src/ComponentD.js
import React from 'react';
import ThemeContext from './ThemeContext';
const D = () => (
<ThemeContext.Consumer>
{value => (
<p style={{ color: value }}>
Hello World
</p>
)}
</ThemeContext.Consumer>
);

pass data to themeProvider

I have a problem whit ThemeProvider in my nextjs project.
I wounder what is the best way to pass data to the theme.
In my getInitialProps inside the /pages/index I get the setting data, and the ThemeProvider tag is in /pages/_app.js wrapper <Component />.. how can I pass the data from index to _app? any idea?
Thanksss!!
here is my code:
/pages/_app.js
import App from "next/app";
import React from "react";
import Head from "next/head";
/* Styles */
import { ThemeProvider } from "styled-components";
import theme from "../styles/theme/primary";
class MyApp extends App {
render() {
const { Component, pageProps } = this.props;
return (
<>
<ThemeProvider theme={theme}> // Here ThemeProvider whit theme
<Header />
<Container>
<Component {...pageProps} />
</Container>
<Footer />
</ThemeProvider>
</>
);
}
}
export default MyApp;
pages/index.js
import React, { useState, useEffect } from "react";
/* Others */
import { getData } from "../helper/api";
const Index = props => {
const res = props.data;
return (
<>
<Home data={res} />
</>
);
};
Index.getInitialProps = async ({ res }) => {
try {
let req = await getData(); // Here I get the settings.
return { data: req };
} catch (e) {
console.log(`Error: ${e}`);
return { data: null};
}
};
export default Index;

Next JS Layout component, pass props to children

I have found a code that solved my problem in Next JS re rendering when changing pages. But now i need to send props to the children component. I got no idea how i can make it works here, this is my layout.js code. As you can see i can send props to Header component but for children i dont know how, because it is a variable and not a component.
import Header from "../components/header";
import Footer from "../components/footer";
import { Fragment } from "react";
export default function Layout({ children, ...pageProps }) {
return (
<Fragment>
<Header
isRegisterPage={pageProps.isRegisterPage}
isLoginPage={pageProps.isLoginPage}
outHome={pageProps.outHome}
/>
{children}
<Footer />
</Fragment>
);
}
Thank you for the help

Have you considered using React's Context API? The idea is that when using the Context API your component's state get's lifted, to be managed at a global scale. If a component needs a prop, instead of passing props down manually (prop drilling) you can simply wrap you component in what's known as a context provider. This will allow that Component to access the global state of your application. This is good because, when your application gets bigger, you may need to pass props down through many components which can clutter and add unneeded confusion.
React provides some great documentation to set your React application up to use the Context API. Highly recommend checking it out!
https://reactjs.org/docs/context.html

Try this
import Header from "../components/header";
import Footer from "../components/footer";
import { Fragment } from "react";
export default function Layout({ children, ...pageProps }) {
function recursiveMap(children, fn) {
return React.Children.map(children, child => {
if (!React.isValidElement(child) || typeof child.type == 'string') {
return child;
}
if (child.props.children) {
child = React.cloneElement(child, {
children: recursiveMap(child.props.children, fn)
});
}
return fn(child);
});
}
// Add props to all child elements.
const childrenWithProps = recursiveMap(children, child => {
// Checking isValidElement is the safe way and avoids a TS error too.
if (isValidElement(child)) {
// Pass additional props here
return cloneElement(child, { currentUser: { ...user } })
}
return child;
});
return (
<Fragment>
<Header
isRegisterPage={pageProps.isRegisterPage}
isLoginPage={pageProps.isLoginPage}
outHome={pageProps.outHome}
/>
{childrenWithProps}
<Footer />
</Fragment>
);
}

You can use React's cloneElement to achieve that.
React.cloneElement(children, {
isRegisterPage: pageProps.isRegisterPage,
isLoginPage: pageProps.isLoginPage,
outHome: pageProps.outHome
})
Complete example in your case:
import Header from "../components/header";
import Footer from "../components/footer";
import React, { Fragment } from "react";
export default function Layout({ children, ...pageProps }) {
return (
<Fragment>
<Header
isRegisterPage={pageProps.isRegisterPage}
isLoginPage={pageProps.isLoginPage}
outHome={pageProps.outHome}
/>
{
React.cloneElement(children, {
isRegisterPage: pageProps.isRegisterPage,
isLoginPage: pageProps.isLoginPage,
outHome: pageProps.outHome
})
}
<Footer />
</Fragment>
);
}

From the answer of Lucas Raza, below is an example that uses Context API to apply themes to different components
1.Create a context File
//ThemeContex.js
import { createContext, useState } from "react";
export const ThemeContext = createContext();
export const withThemeContext = Component => {
const WrappedComp = props => {
const [darkColor,lightColor] = ["#3b3b3b", "#ddd"]
const [lightBackgoround,darkBackgoround] = ["#ececec","#1d2a35"]
const darkTheme = {
backgroundColor: darkBackgoround,
color:lightColor,
}
const lightTheme = {
backgroundColor: lightBackgoround,
color:darkColor,
}
const themes = {
darkTheme, lightTheme
}
const [theme, setTheme] = useState(lightTheme)
const children ={
theme,
themes,
setTheme,
}
return(
<StylesContext.Provider value={{...children}} >
<Component {...props} />
</StylesContext.Provider>
)
}
return WrappedComp;
}
In _app.js, import withThemeContext higher component and wrap MyApp with it when exporting it.
import { withThemeContext } from '../components'
function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />
}
export default withThemeContext(MyApp)
You can know use theme any where in a component
import { useContext } from 'react'
import {ThemeContext} from '../components'
export default function Home() {
const { theme } =useContext(ThemeContext)
return (
<div id="home" style={theme}>
// Home logic...
</div>
)
}
