Understanding the Difference Between Create-React-App Setup with and without a Node.js Server

As a developer venturing into the realms of React, you might have encountered different setups while building full stack applications. One of the common dilemmas newcomers face is whether to use create-react-app in conjunction with a Node.js backend server, or to rely solely on create-react-app without integrating a backend server. In this guide, we'll explore these two distinct approaches, their advantages, and when you might want to choose one over the other.

The Two Approaches

There are primarily two ways to structure your application when working with create-react-app:

Combined Front-End and Back-End Code: This approach involves setting up both your front-end and back-end code together in a single project structure.

Separate Front-End and Back-End Code: This structure prefers a clean separation of concerns by keeping your front-end and back-end in different projects.

Combined Front-End and Back-End

If you choose to combine your front-end and back-end, you can make your workflow more convenient by using one command to start both the server and the React application simultaneously. Typically, you would adjust your package.json scripts to include something like:

In this setup, nodemon watches for changes in your backend code, while react-scripts spins up your React development server. This approach is beneficial for smaller projects where rapid prototyping is necessary, but it can lead to complications as your application scales.

Separate Front-End and Back-End

On the other hand, separating your front-end and back-end has several advantages, especially concerning maintenance and deployment. Here’s why you might want to consider this approach:

Clear Separation of Concerns: The front-end and back-end can evolve independently. The front-end should communicate only via APIs, meaning that it doesn't have to worry about the back-end's specific implementation details. This makes your codebase cleaner and easier to manage.

Flexibility for Future Changes: If you ever decide to switch your back-end technology, for example from Node.js to Deno.js, having them separated means fewer issues. You would only need to modify your back-end deployment without worrying about the front-end details that were tightly coupled to your original back-end.

Ease of Deployment: Keeping front-end and back-end separately allows you to deploy them independently. For instance, you might deploy your React app to a service like Netlify or Vercel, while deploying your Node.js server to Heroku or DigitalOcean.

Conclusion

Ultimately, the decision on whether to use create-react-app with or without a Node.js backend server revolves around your project’s needs. For simple, smaller projects that require quick development cycles, combining both may be enough. However, for larger projects with potential for growth, separation is the way to go. This not only promotes better coding practices but also offers flexibility for future adjustments and scalability.

By understanding the implications of each approach, you can make informed decisions that lead to a more efficient development process. Happy coding!
