Import module from node_modules (create-react-app)

Question

How do I import modules from outside src directory?

./src/App.js
Module not found: Can't resolve 'material-ui' in '/Users/suvo/GitHub/portfolio/src'

According to react-material-icons page, I was supposed to import as follows:

import mui from 'material-ui';

the error's strange. i got import $ from 'jquery'; just next to import mui... and it works fine. What's more, if i create a new project and add react-material-icons, the npm won't start, showing an error:

> [email protected] start /Users/suvo/GitHub/myapp
> react-scripts start

sh: react-scripts: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! [email protected] start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

Solution

Just remove the . in front of the package name.

import mui from 'material-ui';

Packages you install using npm install or yarn install are saved to node_modules directory. You can import them by just specifying package name.

import React from 'react';
import mui from 'material-ui';

import AlarmIcon from 'react-material-icons/icons/action/alarm';

export default class Alarm extends React.Component {
  render() {
    return (
      <AlarmIcon/>
    );
  }
}
