And then you started working on your outset React application with Create React App, and you lot've reached the development stage when it's fourth dimension to finally deploy your app. If your tool of selection for this is Heroku, you might do some research and realize that the documentation regarding this topic contains very picayune data. Because I was recently in a similar situation while building my own React application, I figured I would mankind out the steps that I went through in order to get this done.

I will mention from the start that I decided to go with the employ-a-simple-Express-server style, so in example you prefer other means of doing this, you lot might discover useful documentation in the React deployment docs.

Pace 1: Create Your React Application (If Y'all Haven't Already)

If you lot are reading this, y'all most likely already accept a functioning React application. But if you don't and you just want to go through the whole process (from creating it to deploying it), I volition showtime with the steps required to create a very basic React app.

1. Brand sure you lot have Node.js and npm installed.
2. Open up your terminal of choice, and run the post-obit command by replacing my-app with the proper noun of your application.

          npx create-react-app my-app        

3. After the procedure is done, change directory (cd) into the binder that was created for your app, and first the development server for a quick preview of what yous created.

          cd my-app
npm start        

iv. Push your code to Github. I am going to assume you already know how to exercise that, so I won't go into these details.

Pace 2: Create an Express Server

In the root of your project, create a new folder chosen "server" (for case), and inside of it, add a file called "server.js".

The tool that I used to create the server is called Limited, which is a smashing tool for creating spider web servers with Node. There are dozens of tutorials on the web which you tin can go through in order to learn this tool, just in our case, you just need to write a few lines of code in club to generate your own server.

Then allow'south brainstorm!

1. Install the latest version of Express.

          npm install express --salve        

ii. Import Express, and create a new instance of Express.

          const limited = require('express');
const app = express();        

three. Tell Express to serve up the public folder and everything within of information technology.

                      const path = require('path');            
const express = require('express');
const app = limited();                      const publicPath = path.join(__dirname, '..', 'public');                                app.use(express.static(publicPath));                  

Basically, we laissez passer in all of the pieces of the path, and path.join puts them together. The effect is and so passed into app.utilize(express.static()), so Express volition know which files to serve.

4. Starting time the server by telling it which port to use. I am using port 3000 on my local surroundings; however, Heroku volition assign a port for your app after deploying it, so both cases should be covered.

          const path = require('path');
const express = crave('express');
const app = limited();
            const port = process.env.PORT || 3000;            
const publicPath = path.join(__dirname, '..', 'public');          app.utilize(limited.static(publicPath));                      app.listen(port, () => {
              console.log(`Server is upwardly on port ${port}!`);
});                  

5. Brand sure your index.html file is served, in case the user requests a resources currently not in the public folder.

          const path = require('path');
const express = require('limited');
const app = express();
const publicPath = path.join(__dirname, '..', 'public');
const port = process.env.PORT || 3000;          app.use(express.static(publicPath));                      app.get('*', (req, res) => {
              res.sendFile(path.bring together(publicPath, 'index.html'));
});                    app.listen(port, () => {
            panel.log('Server is upward!');
});        

At this bespeak, if everything went well, you should be able to test your server locally to make sure everything was set correctly. So you tin move on to actually deploying on Heroku.

In order to exercise that, you simply need to create your production build past running npm run build. Then go to your last and run node server/server.js, which should boot upwards your server, making your app available to utilize at http://localhost:3000.

This is basically everything that your server file should incorporate:

Pace three: Deploy on Heroku

1. In case you don't have a Heroku account already, create one here.
2. Once more, if y'all don't have this already, install heroku-cli. More details on that hither.
3. Go to your terminal, and log in to Heroku by running heroku login and entering your credentials when prompted.
4. Create your Heroku awarding by running the following command in the last (and, of course, replacing my-app with the name of your own app).

          heroku create my-app        

At this indicate, you should take ii Git remotes for your app: the original one and the one that was created by Heroku. In guild to check this, just run git remote.

5. When Heroku starts your application, it is going to try to run the start script in your package.json. Therefore, this script should be changed to:

          "start": "node server/server.js"        

half-dozen. Push your code to the Heroku remote repository.

          git push heroku principal        

And that's it! Your React app should now be deployed to Heroku!

You tin can open information technology directly from the terminal past running heroku open.

That'southward all, folks!

Please let me know if yous give this a try and run into any problem or if annihilation I wrote here is not clear or easy to follow. I am always open to feedback.
