Deploy Your React App To Heroku

Before you jump into this tutorial you do need to have a few things installed first before you can start.

🚨If your goal is to combine React UI + API (Node, Ruby, Python…) into a single app, then this tutorial is not the answer.

Requirements:

1. Node / NPM — Click the link and download the installer
2. Git — Click the link and download the installer
3. Heroku CLI — Click the link and download the installer

Steps:

1. Sign up for Heroku
2. Setup our React App for deployment
3. Create Heroku git repository

Step 1 — Sign up For Heroku

Visit Heroku for free hosting

This step explains itself, we need to sign up for Heroku before we can do any deployment. So head over to Heroku and sign up. Once you signed up make sure you head over to your email and confirm your account.

Step 2 — Setup React App

Open up your React app (I’m using create-react-app) and open up your package.json file. If your using create-react-app we’re going to add a new object called engines. Inside of our engines object, we need to specify the versions for npm and node. To do this open up your terminal and type in:

• npm -v

Press enter

• node -v

Press enter

Your versions may be different than mine, but that's fine. Once you specified your engine versions save your file.

Step 3 — Create Heroku Git Repository

With your terminal still open navigate to your React app folder and change directory into it. Now we need to connect our project to Heroku. If you haven’t already installed the Heroku CLI. To make sure it’s installed correctly run this command:

• heroku --version

You should see your Heroku CLI version. Once that is installed we need to setup up Heroku git repository by running these commands:

1. heroku login (Enter your Heroku credentials)
2. git init
3. git add .
4. git commit -m “initial commit”
5. heroku create (You should see two links after running this command. Copy the second one)
6. git remote add heroku PASTE THE LINK YOU JUST COPIED
7. git push heroku master

Once you run the last command Heroku will start to run some tests on your app. If everything goes right you should see a successful deploy message. Now you’re able to navigate to your app by running:

• heroku open

Anytime you make changes to your app and want to re-deploy the only commands you need to run are:

1. git add .
2. git commit -m “any message goes here”
3. git push heroku master

Easier Method 😁

Now that I made you go through all of that process, there is an easier method if you use Github. All you have to do is log into your Heroku account; click “new” then “create new app” and give your app a name. After clicking create you should be greeted with a dashboard for the app you just created. Navigate to the deploy tab and sync your Github account with Heroku. After syncing your Github account and can search for the repository you want to sync with Heroku by scrolling down to “App connected to Github” section and searching for the repository you want to sync. You can also set up automatic deployment, so every time you push to the master branch Heroku will rebuild your app for you.

You forgot one important step I beleive.

Before deploying the app go to:
Heroku dashboard > settings > buildpacks > add buildpacks and then add github.com/mars/create-react-app-b...

Or, in command line you can do

heroku buildpacks:set github.com/mars/create-react-app-b...

If you don't do this step, heroku will deploy the development build (which is slow) of your react app instead of the optimized production build.

[Keerthilingu]

Yes, github.com/mars/create-react-app-b... build pack is required for create-react-app template (static sites).

In Heroku dashboard, under settings> buildpack - I changed from node build pack to github.com/mars/create-react-app-b... and then react static web page started working (or buildpack can be set via Heroku CLI also).

If your app is involving, node backend , then checkout github.com/mars/heroku-cra-node

[Nobu]

I really appreciate you!
 Finally, I deployed my app to Heroku correctly.

Before deploying, I spent almost 5 hours.

[Sameer Katija]

Well, ThankYou Nitin. I wasn't able to upload, but your comment worked Thanks buddy, <3

[Thidasa Pankaja Paranavitharana]

Hey, I've deployed few projects on Heroku. But I find the app loads slow with the default buildpack (maybe it's just me).
So I'm using this builpack. It's pretty straight forward .

you just have to use

heroku create $APP_NAME --buildpack github.com/mars/create-react-app-b...

for the 5th step which you use Heroku CLI.

Just wanted to give some info :)

[Shakhor Smith]

This looks like it's for static sites. I'll definitely check this out the next time I convert one of my apps to static.

Everytime I have getting this error -
heroku : The term 'heroku' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name,

or if a path was included, verify that the path is correct and try again.

Makes the world most genious easy-to-read tutorial for deploying an App.
Tells in end there is an easier method.

I'm done! So Great :D

[Aravindakksan]

This worked out man!!

[VIPIN-creator]

I am getting 404 not found nginx .
Please Help

[siyabongagoqoza]

I was getting the same thing too....until i tried the easier method he provided us

[Nikhil Saini]

You didn't mention anything about the Procfile which is the most important thing when you deploying a react project.

[Lachlan24]

Hey, i followed all the steps but some reason heroku is displaying the default template app that is created when you first create a react app, As opposed to my app. What am i doing wrong ?

[dangsteve1]

Thanks for the write up - it was super helpful!

I admit... you got me putting the easy way in the bottom of the article. Sometimes, its better to learn the hard way.

[Abdullah Oladipo]

Thanks. This with Nitin comment dev.to/niinpatel/comment/5b6p saved me after several hours

[rinahs]

hello guy! i'm now deplyed my app in heroku ! what a doing after?

[jay]

This guide is human-friendly. So much trash out there. Thanks man 👌

[Chandrasekar]

Hey..I followed your step. Its working..but in react chrome extension indicates "This page is using the development build of React. 🚧

Any Idea.

I am having an issue. Getting “failed to push some refs” when trying to push.

[Gideon S Crawley]

Hi I'm having a hard time deploying my react app to heroku. I noticed you don't have a build folder, or a server folder.
Should i delete those before trying this method?
