Build a Full Stack Web App with Node.js and React: A Step-by-Step Guide

React and Node JS are the most talked-about technologies right now, especially when you look at the trends in technology. Many developers in the field of web development use React and Node.js to produce creative solutions. A dynamic website is essential in the modern digital era since it serves as an organization’s public persona.

Given this, combining Node.js with React technology can result in incredible outcomes. You can create reusable user interface elements using React, thanks to its flexible design philosophy. Because of their event-driven nature, they can handle high traffic levels more effectively than other frameworks. React full-stack web app development combined with Node lets developers create web apps that are simple to upgrade.

If this inspires you to develop a full-stack application like Netflix but you are unsure how to start, we will walk you through the process in this blog post using React and Node.js.

Perks of Using Node.js with React for Full-Stack Web App Development

When it comes to full-stack web application development, using both nodes.js and React gives you the following benefits:

●       Less Code To Learn: Since both React and Node.js use JavaScript, you just have to master one language to create a front-end and back-end web application.

●       Smooth And Speedy Apps: Node.js makes real-time apps operate swiftly, while React helps manage large numbers of users on your website.

●       Build More Quickly: React and Node.js work well together since they share the same language, which will save you time and money when developing.

●       Create Single-Page Apps: SPAs for modern websites that load quickly and dynamically to improve user experience.

●       Simple To Use: Consider React and Node.js as instruments (such as a hammer and saw) that you may use to create any kind of JavaScript website from the ground up.

How Do You Create A Full-Stack Web App With React and Node.js? Step-by-Step Guide

Building a full-stack web app becomes simpler once you understand these steps:

Step 1: Creating a Backend using Node.js

Create a project folder. Then name it anything you desire. One good example is Node-React-App.

Launch the code editor by dragging the newly generated folder inside.

In your terminal, create a Node project:

●       Kind: npm init -y

●       This generates a package.json file for project management.

Later server code:

●       A server folder and its corresponding index.js file will be created. The server is located here.

Express: Express is useful for developing web servers.

●       In your terminal, execute npm i express to begin using it.

Make the server run:

●       To use npm, start to start the server and add a script to package.json.

●       After obtaining the script, use npm start to launch the server.

Step 2: Creating an API Endpoint

It is now recommended that you utilize your Node and Express server as an API to feed data into your React application so that you can modify it or perform other server-only functions.

Mobile app developers must restart the server because we made some changes to the Node scripts. Additionally, developers can quickly launch the script by simply pressing Command/Ctrl+C. Run npm and start again to restart it after that.

Step 3: Create An App Frontend With React

In this step of the full stack web application development, proceed to the frontend development by utilizing React. Using create-react-app, you must first open a new terminal tab and start a new React project called client in order to develop a front using REACT.

npx create-react-app client

You will then have an installed React app along with all of its dependencies. Because the app code needs to be changed, you can engage a mobile app developer to construct a front end. Here, you must update your package.json file with a property named proxy.

By including this property in your app code, developers will be able to send requests to the Node server without needing to supply the origin when submitting a network request.

To begin with, make sure you cd into the newly generated client folder. Next, you can instruct developers to launch the application at localhost:3000.

Here, we have included the command that you may type straight into the terminal to make things easy to follow.

cd client

npm start

Compiled successfully!

You can now view clients in the browser.

Local: [http://localhost:3000](http://localhost:3000)

Step 4: Make the HTTP Requests From React To Node

It’s likely that up until this point, your full stack with React and Node.js frontend and backend are ready; now, it’s time to add functionality and enable API interaction for your app. Developers should go to the App.js component in the src folder and learn how to get data from the previously constructed /API endpoint now that you have a functional React APP.

They must utilize useEffect to send an HTTP request after gaining access to the src folder. Here, all you have to do is use the Fetch API to make a straightforward GET request to your backend, and you should receive your data back as JSON.

The message property will be available once developers have converted the data back to JSON, and you can then save it in a state variable named data. Developers will be able to show that message on the app page by using this command. Here, we advise utilizing a JSX conditional to indicate that, in the event that our data is not yet available, the message “Loading” should be displayed.

Step 5: Build and Deploy Your Application

Taking your React application online

●       We used Node.js to develop your React app. Now, let’s use Heroku to publish it.

●       Initially, remove the Git repository (in the client folder) that create-react-app created. A fresh one will be configured in the primary project folder.

Getting everything to function together

●       Make sure the React frontend and Node.js backend are delivered on the same domain (such as when developers post.

●       You can link your React app to the Node.js API, which processes requests with the assistance of an app development business.

●       When people visit your website, they can contribute code to your server that will allow your React app to be served.

Getting ready for the Heroku

●       Update the package.json file on your server using a build script. As a result, your React app will become production-ready.

Using Heroku for deployment

●       Use the Heroku login on your terminal to access Heroku.

●       For your app, adhere to Heroku’s deployment guidelines (located under the “deploy” page).

●       Use these commands to push your code to Heroku (change insert-your-app-name-here with the name of your app):

So, your Node.js and React apps are now live!


Now that you know that combining Node JS with React can really help you reach new heights, what are you going to do next? Hiring full-stack developers, node.js with a ton of expertise and skill is the ideal method to build a dynamic website. What about creating a web application with NodeJS and React? You won’t want to look back once you work with top developers!
