I'm having a problem with the relative path for my react app. It seems super simple but I've double checked everything and I still can't get it to work.
The path is src > components(folder) > Navigation(folder) > navigation.js
The terminal says: "Failed to compile.
./src/App.js
Module not found: Can't resolve './components/Navigation/navigation' in '/Users/misbahhemraj/Desktop/facefind/src'"
This is my code in my app.Js:
import React, { Component } from 'react';
import navigation from './components/Navigation/navigation';
import './App.css';
class App extends Component {
render () {
return (
<div className="App">
<navigation />
{/*<Logo />
<ImageLinkForm />
<FaceRecognition />*/}
</div>
);
}
}
export default App;
This is my code in navigation.js
import React from 'react';
const Navigation = () => {
return (
<nav>
<p> Sign Out </p>
</nav>
)
}
export default navigation;
I've tried changing the ports and changing the syntax of the import statement but I can't get it it work. Any advice would be appreciated - thank you so much!
Look at your export component name, you have navigation and your component name it´s Navigation
import React from 'react';
const Navigation = () => {
return (
<nav>
<p> Sign Out </p>
</nav>
)
}
export default Navigation;

Im making a simple typescript project, but can't manage to solve the following error:
Compiled with problems:
ERROR in ./src/index.tsx 7:0-28
Module not found: Error: Can't resolve './App' in '/Projects/test/src'
Any suggestions??
Here's the files..
Home:
import React from "react"
export const Home = () => {
return (
<>
<div>
<p>Essa é a pagina home</p>
</div>
</>
);
};
export default Home;
App.tsx:
import React from 'react';
import { Home } from './pages/Home';
export function App() {
return (
<Home />
);
};
index.tsx:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import { App } from './App';
const ApplicationWrapper = () => {
return (
<App />
);
};
ReactDOM.render(
<React.StrictMode>
<ApplicationWrapper />
</React.StrictMode>,
document.getElementById('main'),
);
FILE STRUCTURE:
When the code is exported and with a default keyword, that means you only can import by using import Alias from './module'. If you want to import through Object Destructuring, it needs to export a Component or module without using the default keyword.
Last line of Home component.
export { Home };
When it needs to import.
import { Home } from './path-to-component';
you can export once at Home component like this:
import React from "react"
const Home = () => {
return (
<>
<div>
<p>Essa é a pagina home</p>
</div>
</>
);
};
export default Home;
Please check, App.tsx file should be in index.tsx folder. ie both files should be in /Projects/test/src folder.
I am in the process of learning react. Here i got stuck in some basic problems. I learn concept of props and parent-child components in react, but when i try to implement it, it shows error. Please help. I have one parent component named 'Portfolio' and one child component named 'PortfolioBox'. I try to pass title props in PortfolioBox. Here is my sample code. Issue comes while starting the react app 'npm start'. It shows error 'Portfolio is not defined'.
Portfolio Component
import React from 'react';
import PortfolioBox from './PortfolioBox';
import './portfolio.css';
function Portfolio()
{
return (
<div className="row portfolio-container">
<PortfolioBox title="One" />
<PortfolioBox title="Two" />
<PortfolioBox title="Three" />
<PortfolioBox title="four" />
</div>
)
}
export default Portfolio;
Portfolio Box Component
import React from 'react';
function PortfolioBox(props)
{
console.log(props);
return(
<div className="col-md-4 portfolio-box">
<h3>{props.title}</h3>
<p>Description</p>
</div>
)
}
export default PortfolioBox;
App.js File
import React from 'react';
function App() {
return (
<div className="container-fluid">
<Portfolio />
</div>
);
}
export default App;
You are missing an import statement in your app.js file:
import React from 'react';
import Portfolio from './Portfolio'; // If your file is in the same directory
function App() {
return (
<div className="container-fluid">
<Portfolio />
</div>
);
}
export default App;
this is my simple home.js code. None relevant code has been removed.
import Banner from '../components/Banner'
export default function Home() {
return (
<Hero>
<Banner title="luxurious rooms" subtitle="delux rooms starting at $299">
<Link to="/rooms" className="btn-primary">
Our rooms
</Link>
</Banner>
</Hero>
and this my banner.js
import React from 'react'
export default function Banner({childern,title,subtitle}) {
return (
<div className="banner">
<h1>{title}</h1>
<div />>
<p>{subtitle}</p>
{childern}
</div>
)
}
I don't understand why it is not rendering.
In the bedg I contd see <banner>. tag inside of hero.
How can I solve this issue?
Ok, I created a pen for this, but it's not saving so I'll add the code here. It looks like you are taking a difficult approach for a relatively easy concept. When you pass props to a component, you access them within that component using this.props.nameOfProp. You don't need to pass link as a child, just add Link inside the child component, and pass the info you need for the Link as props.
EDIT: Here's a working example https://codesandbox.io/embed/elegant-fast-m52bt
import React from "react";
import ReactDOM from "react-dom";
import Banner from "./Banner";
import { BrowserRouter as Router } from "react-router-dom";
class App extends React.Component {
render() {
return (
<div>
<Banner
title={"luxurious rooms"}
subtitle={"delux rooms starting at $299"}
path={"/rooms"}
classList={"btn-primary"}
/>
</div>
);
}
}
ReactDOM.render(
<Router>
<App />
</Router>,
document.querySelector("#app")
);
Then your banner should look something like this:
import React from "react";
import { Link } from "react-router-dom";
class Banner extends React.Component {
render() {
return (
<div className="banner">
<h1>{this.props.title}</h1>
<p>{this.props.subtitle}</p>
<Link
to={this.props.path}
className={this.props.classList}
>
Link Text (could also be a prop)
</Link>
</div>
);
}
}
export default Banner;
I'm very new to React and ran into an issue when trying to import a "sub-component", for lack of a better word.
In my App.js file I imported my header class: import Header from './Components/Header/Header'; Which worked fine.
Within my Header.js file I'm using router to select different components. However, when I try to import my Home class: import Home from '../Subcomponents/HomePage/HomePage'; I receive the following error: Module not found: Can't resolve '../Subcomponents/HomePage/HomePage'
My file structure is:
app.js
Components/Header/Header.js
Subcomponents/HomePage/HomePage.js
App.js Code:
import React, { Component } from 'react';
import Header from './Components/Header/Header';
import Footer from './Components/Footer/Footer';
import Body from './Components/Body/Body';
import './Assets/css/mainCSS.css';
class App extends Component {
render() {
return (
<div className="App">
<Header />
<Body />
<Footer/>
</div>
);
}
}
export default App;
Header Code:
import React from 'react';
import Home from '../Subcomponents/HomePage/HomePage';
import { Router, Route, Link } from 'react-router-dom';
const header = () => {
return <header>
<Router>
<nav>
<ul>
<li>
<Link to='/'>Home</Link>
</li>
</ul>
<hr />
<Route excat path ="/" component={Home} />
</nav>
</Router>
</header>
}
export default header;
HomePage Code:
import React from 'react';
const homepage =() =>{
return <p>
homepage working
</p>
}
export default homepage;
Am I doing something wrong here or is this not possible in React? Any advice would be greatly appreciated!
Thanks!
From Header.js, ../ puts you into Components, not into the parent. It should be '../../Subcomponents/HomePage/HomePage'.
Also, imho: within each component folder, name the file index.js so that it will be automatically exported. Than you can just do: '../../Subcomponents/HomePage'
I have recently installed Material UI into my Meteor application using npm install --save material ui
I have gotten the <Header /> component showing up in my app.js file, but whenever I add other components, localhost:3000 simply displays a blank page. Please see my code below:
header.js
import React, { Component } from 'react';
import AppBar from 'material-ui/AppBar';
class Header extends Component {
render() {
return(
<AppBar
title="Header"
titleStyle={{textAlign: "center"}}
showMenuIconButton={false}
/>
);
}
}
export default Header;
app.js
import React from 'react';
import ReactDOM from 'react-dom';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import Header from './components/header';
import NewPost from './components/new_post';
const App = () => {
return (
<MuiThemeProvider>
<Header />
</MuiThemeProvider>
);
};
Meteor.startup(() => {
ReactDOM.render(<App />, document.querySelector('.render-target'));
});
THE ABOVE CODE WORKS WELL (see screenshot below)
However, if I add another component I get a blank screen
header.js is the same
new_post.js
import React, { Component } from 'react';
import TextField from 'material-ui/TextField';
class NewPost extends Component {
render() {
return (
<TextField
hintText="Full width"
fullWidth={true}
/>
);
}
}
export default NewPost;
app.js
import React from 'react';
import ReactDOM from 'react-dom';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import Header from './components/header';
import NewPost from './components/new_post';
const App = () => {
return (
<MuiThemeProvider>
<Header />
<NewPost />
</MuiThemeProvider>
);
};
Meteor.startup(() => {
ReactDOM.render(<App />, document.querySelector('.render-target'));
});
The result is simply a blank screen
Why does adding one more component (<NewPost />)inside of <MuiThemeProvider> result in a blank screen? I referred to the material-ui documentation and their sample projects but their application structure is not similar to mine. Any advice? Please let me know if you need more info to make this question clearer.
Wow very strange but I managed to get it working by simply adding a <div>
app.js
const App = () => {
return (
<MuiThemeProvider muiTheme={getMuiTheme()}>
<div>
<Header />
<NewPost />
</div>
</MuiThemeProvider>
);
}
Meteor.startup(() => {
ReactDOM.render(<App />, document.querySelector('.render-target'));
});
I would really appreciate if anyone could explain why adding a div makes this all work. Thank you!

If you look at the browser warning, "Invalid prop children of type array supplied to MuiThemeProvider, expected a single ReactElement.".
So, when you add a <div/> around your components, it wraps them together and turns them into a single react element.
MuiThemeProvider renders as null so you have to wrap children do anything - for example React.Fragment
