    Your syntax is valid. JSX is syntax sugar for React.createElement(type) so as long as type is a valid React type, it can be used in JSX "tags". If Button is null, your import is not correct. Maybe Button is a default export from component-library. Try:

    import {default as StyledButton} from "component-library";
    

    The other possibility is your library is using commonjs exports i.e. module.exports = foo. In this case you can import like this:

    import * as componentLibrary from "component-library";
    

    Update

    Since this is a popular answer, here a few more tidbits:

    export default Button              -> import Button from './button'
                                          const Button = require('./button').default
             
    export const Button                -> import { Button } from './button'
                                          const { Button } = require('./button')
             
    export { Button }                  -> import { Button } from './button'
                                          const { Button } = require('./button')
             
    module.exports.Button              -> import { Button } from './button'
                                          const { Button } = require('./button')
    
    module.exports.Button = Button     -> import { Button } from './button'
                                          const { Button } = require('./button')
    
    module.exports = Button            -> import * as Button from './button'
                                          const Button = require('./button')
