Creating an action creator

Let's create a new folder called actions in our project's ~/snapterest/source/actions directory. Then, we'll create the TweetActionCreators.js file in it:

import AppDispatcher from '../dispatcher/AppDispatcher';

function receiveTweet(tweet) {
  const action = {
    type: 'receive_tweet',
    tweet
  };

  AppDispatcher.dispatch(action);
}

export { receiveTweet };

Our action creators will need a dispatcher to dispatch the actions. We will import AppDispatcher that we created previously:

import AppDispatcher from '../dispatcher/AppDispatcher';

Then, we will create our first action creator receiveTweet():

function receiveTweet(tweet) {
  const action = {
    type: 'receive_tweet',
    tweet
  };

  AppDispatcher.dispatch(action);
}

The receiveTweet() function takes the tweet object as an argument, and creates the action object with a type property set to receive_tweet. It also adds the tweet object to our action...
