React unable to import component -- module not found

Question

I just started with React.js and I am unable to import component.

I have this structure as followed by this tutorial (YouTube link) :

-- src
----| index.html
----| app
------| index.js
------| components
--------| MyCompontent.js

This is my index.js:

import React from 'react';
import { render } from 'react-dom';

import { MyCompontent } from "./components/MyCompontent";

class App extends React.Component {
    render() {
        return (
            <div>
              <h1>Foo</h1>
              <MyCompontent/>
            </div>
        );
    }
}

render(<App />, window.document.getElementById('app'));

This is MyComponent.js:

import React from "react";

export class MyCompontent extends React.Component {
  render(){
    return(
      <div>MyCompontent</div>
    );
  }
}

I am using this webpack file (GitHub link).

However, when I run this, my module fails to load.

I get this error in the browser console:

Error: Cannot find module "./components/MyCompontent"

Can't figure out what went wrong here.

Answer 1

For anyone coming here without a typo, and is using Webpack, be sure to check for a clause like this:

resolve: {
    extensions: [".jsx", ".js"]
},

in your webpack.config.js.

This tells your transpiler to resolve statements like:

import Setup from './components/Setup'

to

import Setup from './components/Setup.jsx'

This way you don't need the extension.

Answer 2

You have a typo in your import. You're requesting MyCompontent. Change to:

import MyComponent from "./components/MyComponent";

And all typos as well.
