ReactJS failing to import components
18:21 21 Sep 2017

I'm very new to ReactJS but from what I gather the following code should work and it doesn't.

I've created a new ReactJS project using the npm command create-react-app. In my project folder I've installed Google's material ui with npm install --save material-ui@next.

I'm getting various errors depending on what I'm trying to import from 'material-ui'.

import Card from 'material-ui/Card'

I'm using VS Code as my editor and if I hit F12 on 'material-ui/Card' it shows me that Card is the default export, and the import above works.

import {Card} from 'material-ui'

If I hit F12 on 'material-ui' it shows me that Card is a named export, and the import above works.

Where I run in to trouble is when I try to import other things. For instance:

import {Card, CardText} from 'material-ui'

Card imports fine, but when I try to use I get the following error:

React.createElement: type is invalid -- expected a string (for built-in 
components) or a class/function (for composite components) but got: 
undefined. You likely forgot to export your component from the file it's 
defined in.

However, as far as I can tell they are both being exported the same exact way.

declare module "material-ui" {
    export import Card = __MaterialUI.Card.Card;
    export import CardText = __MaterialUI.Card.CardText;
}

and digging even further:

export interface CardTextProps {
    actAsExpander?: boolean;
    color?: string;
    expandable?: boolean;
    style?: React.CSSProperties;
    className?: string;
}
export class CardText extends React.Component {
}

Other imports also fail for me when they look like they should work:

import getMuiTheme from 'material-ui/styles/getMuiTheme'

Module not found: Can't resolve 'material-ui/styles/getMuiTheme'

But as far as I can tell, it's there...

reactjs typescript material-ui
