An ‘action creator’ function returns an object (the action). As such, I have jumped straight to explaining ‘action creators’. In my opinion, this abstraction doesn’t reflect the internals of Redux and ends up confusing beginners. When learning about redux you will often learn about just ‘actions’ and not ‘action creators’. Things start to become ever so slightly more nuanced here.

users, emails, names, books, book titles, authors etc. It’s all the information we include in our application, e.g. Pretty simple right? It’s worth noting that this would then be stored in a database, e.g. It is stored in a single JavaScript object. It provides as a ‘single source of truth’ of our applications data. The place where we ‘store’ all of our applications data (aka state). Now we have that image in mind, let's walk through each of the above and see if you can make a connection between it and each of the concepts. Having completed what you need you leave the bank!

#Make visuals great again and redux update#
The bank teller returns to update you that your money had been stored. They then walk to the bank vault and store your money inside. The teller opens the briefcase, read’s slip of paper and picks up the cash. You go into the bank and give the teller at the desk the briefcase. You have a briefcase which has £100,000 in cash and a slip of paper in it that says, “Deposit this money”. Imagine you have a large amount of money and want to deposit it in your bank. As you work through the list, it will help build an image in your mind of what is going on. Within this library there are a few key concepts we should understand.īefore explaining each of them, read the below metaphor which I use to understand what is happening. It allows us to add, edit and remove state in a logical, scalable and secure way. It is a library that has evolved over years of research into how best to manage large, complicated state. Put simply, Redux is a JavaScript library, which manages the state (aka data) of our application. Redux is based on the concepts of functional programming and it will help you follow along.

If you don’t understand functional programming, I would recommend reading my two part series on it – Functional Programming Part 1.

Of course you aren’t expected to be able to understand it from looking at that, but you should take confidence that the concepts, when boiled down are relatively simple.īefore reading this article, I would advise that you should have a good understanding of JavaScript and also of functional programming. As you can see there isn’t too much off it.

Take a look at this code written by Dan Abramov, the creator of Redux – Redux Simplified. Redux is a surprisingly small library, and at it’s most basic it can be written in 97 lines of code.

Having provided some context to where Redux sits in the web development let's look at it in more detail. It's also worth noting that Redux isn't always necessary, whereby if an application has a simple data structure, the React state management, such as the Context API, or just passing it down through props, is often enough. The front end developer will likely utilise a user interface library such as React which they connect to Redux to create an automatically updating User Interface.Ĭonsidering redux is just plain JavaScript, it is possible that the backend developer could use Redux to store data in the database but there are much better methods for the back end of the application so I would advise you just think of Redux as a front end library. The front end developer will then use Redux to pull this data into the front end of the application. An example of the REST API may be the WordPress API, Netlify or Mongo DB. To clarify, let's look at an example example use case.Ī back end developer has implemented a REST API which opens up the applications database for use on the front end. It exists in a strange space between the front and back end of an application which often confuses beginners about its role in an application. Redux is a state management tool which helps us manage data for our applications.
