The article explains how to integrate a React frontend with a Rails API, highlighting that the process is easier than commonly perceived. It guides the reader through the steps of setting up a local React app that communicates with a Rails backend running on different ports. The importance of configuring CORS and efficiently managing the application's loading states and error handling is discussed. This practical example aims to demystify the connection between these technologies and provide readers with a clearer understanding of how they can collaborate.
Connecting a frontend React app with a Rails API is more straightforward than expected, especially when using Docker to handle the setup efficiently.
Throughout the article, I'll demonstrate how to create a React app that seamlessly fetches user data from a Rails backend running on a local server.
With separate ports designated for React and Rails applications, plus proper CORS configurations, the integration process becomes smooth and manageable.
Managing the application's state with loading indicators and error handling is also covered, adding another layer of functionality to the user data fetching process.
