Redux: Hook, Line, and Simple

Redux: Hook, Line, and Simple

The React Redux guides are a bit verbose, to say the least, so I am hoping this quick start guide is simpler.

If you are familiar with React (you should be if you want to understand this) then you understand the trouble of managing state through multiple components and props in what my instructor called ‘prop drilling’. Redux is a great solution for this single source of truth conundrum; however, class component Redux is a lot. You need to map and then dispatch actions from props and it’s just a bit much for how lazy I want to be. Lucky for us, the beautiful people that write Redux gave us Hooks for our functional component lifestyle.

This is not intended as a replacement for the official docs but as a supplement to focus on the relevant points. I have omitted imports and code snippets that are not a factor in making Redux hooks work properly so the focus is on Redux only.

## If you use npm:

npm install react-redux
## Or if you use Yarn:
yarn add react-redux

index.js

In your index.js file, you will do some Redux setup found in their quickstart guide. You create a store and pass your reducer into it. You can have more than one reducer and using combineReducers. You can also compare to their example code.

import { Provider } from "react-redux";
import { createStore } from "redux";
import reducer from "./reducer";

const store = createStore(reducer);
ReactDOM.render(
    <Provider store={store}>
        <App />
    </Provider>
document.getElementById("root")
);

React and React Redux — Connecting to Redux
