How to Use Redux with React for Decentralized Apps?

In this post we have explained how the developers use redux with react a popular JS library for writing smart contracts for decentralized exchanges.

Decentralized exchanges (DEXs) are a rapidly growing sector of the cryptocurrency industry, offering users a secure and decentralized platform for buying and selling digital assets. Here we are going to give you an overview about the use of Redux with React for cryptocurrency exchanges or decentralized exchanges. How it’s used, its importance and necessity to help DEX record real-time data and so on so forth.

Let’s assume you have to build a DEX using React, you may be wondering how to manage your application’s “STATE” in a way that is both performant and scalable at the same time. Sounds tricky, right? It’s not that much. See the best example of using Redux with React here.

One option to consider is using Redux, a popular library for managing state in JavaScript applications and it works perfectly fine for React powered app.

Redux is a predictable state container for JavaScript apps that helps you write applications that behave consistently and are easy to test. It’s a great choice for building DEXs because it allows you to manage your application’s state in a single location, making it easier to track changes and debug any issues that may arise.

To use Redux with React, you would need to install the ‘react-redux’ library, which provides a set of bindings that allow you to use Redux with React. Once you have it installed, you would need to create a Redux store then and provide it to your React components using the ‘Provider’ component that we would show you in the example so you could have a better idea about it.

import { createStore } from 'redux';
import { Provider } from 'react-redux';

const store = createStore(reducer);

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

With the store provided to your React components via the ‘Provider’ you can use the ‘connect’ function to connect specific components to the store and specify which pieces of state should be passed as props. See this example for a better understanding for instance:

import { connect } from 'react-redux';

function mapStateToProps(state) {
  return {
    exchangeRates: state.exchangeRates
  };
}

function mapDispatchToProps(dispatch) {
  return {
    fetchExchangeRates: () => dispatch(fetchExchangeRates())
  };
}

export default connect(mapStateToProps, mapDispatchToProps)(ExchangeRates);

In this example, the ‘ExchangeRates’ component is connected to the Redux store and will receive the ‘ExchangeRates’ piece of state as a prop. It will also receive the ‘fetchExchangeRates’ action creator as a prop, which it can use to dispatch an action to update the ‘ExchangeRates’ in the store.

Using Redux with React can greatly simplify the process of managing state in your DEX and make it easier to scale as your application grows. It’s a powerful tool that is definitely worth considering for your next project.

This is how we can use Redux with React for writing our DEX smart contracts. All such smart contracts built on top of React and Redux are done this way. For detailed tutorials about React and Redux you can visit laramatic.com
