After importing a module in ReactJS npm start wont compile

i am using create-react-app to build a simple gallery based on reddit API using reddit.js

used "npm install --save reddit.js" in the "C:....\reddit-gallery"

wrote some basic code, and then, when using npm start to run it, i keep getting:

Failed to compile.

Error in ./src/App.js

C:....\reddit-gallery\src\App.js

18:9 error 'reddit' is not defined no-undef

while coding it is recognizing the library, but when using npm it does not recognize any code from that library

the code:

import 'reddit.js';

class App extends Component {

constructor(props){
    super(props);

    this.state = {};

    this.loadSubreddit = this.loadSubreddit.bind(this);
}

loadSubreddit(subre){
    reddit.hot(subre)
        .then(response => {
            return response.json();
        }).then(json => {
            console.log(json)
    })

}

componentWillMount() {
    console.log('comp is mounting');
    this.loadSubreddit('cats');
}
