What are the steps to generate a production build directory in a React project?

Currently, I am developing a website utilizing react for the frontend and node.js for the backend. However, I'm unsure of how to deploy it to the live server. After conducting some research, I learned that I need to create a build folder. To provide a clearer picture, let me explain how my folders are set up. I have a main folder called "FRONTEND" where all the react code is stored, and right outside this FRONTEND folder, I have files like server.js, package.json, etc. Should I create separate build folders for the frontend and backend, or is there a way to merge them into one? Additionally, I am using nodemon to run both react and node.js concurrently. Any suggestions or guidance on this matter would be greatly appreciated.

Thank you for your assistance.

If you're looking for a simple and effective way to set up a node backend that handles API requests and also serves frontend files, then your current setup is on the right track. This approach works well for single page applications (SPAs) or basic websites. Essentially, all you need to do is configure Node to serve static files from the FRONTEND folder and default to FRONTEND/index.html (or whatever your main app page is).

For a clear example of how to implement this setup, check out this helpful guide:

If you're using Express, your code might resemble the following:

// Serve static assets
// The if statement is optional but can simplify development with nodemon
if (process.env.NODE_ENV === 'production') {
  // Set static folder
  app.use(express.static('FRONTEND/build'));
  app.get('*', (req, res) =>
    res.sendFile(path.resolve(__dirname, 'FRONTEND', 'build', 'index.html'))
  );
}

Typically, instead of 'FRONTEND', you might use a name like 'client', but there's no reason why FRONTEND wouldn't work just as effectively.

In essence, your Node.js server sets up a route for any file (via the app.get(''* part) to point to your React app file in the build folder. Keep in mind that in development, your React app won't run out of the build folder. Therefore, before uploading everything, remember to run npm run build to generate a production version of your site. Alternatively, services like Heroku may handle the react build process when deploying the files, offering flexibility in approach.
