Action
We'll start by creating the action which will signify when an alert is triggered. We want all of our alerts to be unique so multiple alerts can handled without a problem which we will use uuid.

The action is declared as a function, which takes in 3 arguments (2 required): msg, alertType and timeout. Which we then use call the dispatch function with an object constructed from the arguments, and then after a specified timeout we dispatch another object to remove the same alert.
Note that we curry the dispatch function in this case, this is only possible from using the middleware redux-thunk, which can also be represented as:

To break it down, we've created a React component (class) Alert which takes in alerts as an array, verifies it isn't null or empty, and finally iterates over each element in the alerts array to return a div stylized with the appropriate information.
Reducer
Lastly we have the reducer which we want to handle all the states that can be created by the alert action. Luckily we can do this with a switch statement:

First off what's an API and more specifically what's an API route? API stands for Application Programming Interface, meaning it's how to communicate with the system you are creating. A route within an API is a specific path to take to get specific information or data out of. This post will dive into how to set up API routes in Nodejs with express.
We start by 'importing' express into our route and instantiating a router from the express library.

These 4 methods make up the basic CRUD functionality (Create, Read, Update and Delete) of an application.

As we can see above, the first argument to our API route method is the path, and the following is the callback function (what should happen when this path is hit). The callback function can be a function, array of functions, series of functions (separated by commas), or a combination of all of them. This is useful if you are wanting to do validation before the final POST request is made. An example of this is:
