In this article, we’ll explore how to seamlessly integrate a Node Express backend with a React application created using create-react-app. This step-by-step guide aims to empower developers looking to build full-stack applications effortlessly.
Prerequisites
- Node.js installed on your machine.
- Basic understanding of React and Node.js.
Getting Started
Let’s dive into the steps required to set up your project.
1. Install Nodemon Globally
Nodemon is a utility that automatically restarts your Node application when it detects changes in the filesystem. Install it globally using the following command:
npm i nodemon -g
2. Set Up Server and Client Dependencies
Now, create the directories and install the necessary dependencies. Navigate into the client directory and install packages:
yarn
cd client
yarn
3. Start the Server and Client Simultaneously
To run your server and client at the same time, execute the following command from the root of your project:
yarn dev
4. Running the Production Build
To create a production build and run it on localhost, use the command below:
NODE_ENV=production yarn dev:server
Understanding the Integration
The magic happens through the use of a proxy in your setup. This configuration allows your React application to communicate with your Node Express backend easily.
By adding a proxy field in your client/package.json file like below:
"proxy": "http://localhost:5000"
you instruct the Webpack development server to forward API requests to your Express server, which runs on localhost:5000. This removes the hassle of dealing with CORS issues during development.
Troubleshooting
If you encounter issues, here are some troubleshooting tips:
- Ensure that Nodemon is installed correctly.
- Check for typos in your
package.jsonconfiguration. - Make sure the server is actually running on
localhost:5000. - For any further clarification or assistance, feel free to reach out.
