Is it possible to trigger a Redux action from outside a component?

In order to dispatch and action from outside of the scope of React.Component you need to get the store instance and call dispatch on it like

import { store } from '/path/to/createdStore';
​
function testAction(text) {
  return {
    type: 'TEST_ACTION',
    text
  }
}
​
store.dispatch(testAction('StackOverflow'));
