Setup Redux for Large React Projects — without Tears

Setup Redux for Large React Projects — without Tears

For small React projects, it’s cool passing props between React components, from the Arctic to Antarctica 😃

For small React projects, it’s cool passing props between React components, from the Arctic to Antarctica 😃. With increasing complexity, we pass a bit more props and possibly throw in React Context to manage some state data between nested sibling components.

As the project grows, the need for a proper state management tool becomes unavoidable. This is the sweet spot for a tool like Redux in React projects. However, setting up Redux is considered herculean due to the amount of boilerplate required.

In this post, we’ll set up a redux store suitable for large projects without shedding tears. This post’s scope doesn’t cover setting up Thunk middleware for async actions or persisting a store.

We’ll focus mostly on store creation, project composition, entity reusability, and manageability. A considerable concern amongst developers using Redux in React projects is the convolution of the codebase with the increase in state variables.

What is Redux?

Quick director cut for those unfamiliar with Redux. Redux is a robust state container for JavaScript applications. Peep the barrels in the banner image. Like they hold wine possibly in your cellar, Redux creates a box for application data in your JavaScript application.

Redux creates an application data store and provides logic to retrieve and modify the stored data. Wondering how state management works on the bare minimum? I wrote this post about it using HTML and JavaScript.

With accompanying tools like React-Redux, state management in React apps becomes seamless. With state hoisted from components into the application layer, interactivity in your frontend app becomes almost limitless.

Prerequisites

Knowledge of JavaScript and React.js is required to follow through with this post. We’ll create a simple counter app on CodeSandbox with data from the application state.
