Implementing actions and action creators

In the first chapter, we learned how important actions are in Redux. Only actions can change the state of your application.

Actions in Redux are valid if they have a type property. The rest of the object structure is totally up to you. If you prefer using a standard structure, check out https://github.com/acdlite/flux-standard-action.

Redux actions are simple JavaScript objects with a type property, which specifies the name of the action.

Let's define a simple action, in the src/index.js file:

const createPost = { type: 'CREATE_POST', user: 'dan', text: 'New post' }
console.log(createPost)

Now, save the file. Webpack should automatically refresh the page after modifying and saving a source file (such as src/index.js).
