Deploying DApp to Heroku: Part (4/4)

Github & Heroku

In this part of the tutorial we'll be deploying the react app we built in the previous section.

This project is hosted here.
Link to Github Repo of the project here. This will serve as a reference for you, if at some point you are not able to follow the tutorial.

For this tutorial you need to have your repo on github. If you haven't done it yet follow these instructions to do so.

Signup on Heroku and create new app.

  • Go to Heroku and signup.
  • Create a new app Heroku create new app Give a unique name and select a region.

Adding Buildpacks

Buildpacks are scripts that are run when your app is deployed. They are used to install dependencies for your app and configure your environment.

Go to app settings.


Here we need to add two buildpacks, one because the project we want to host frontend is a subdir in the project and second because heroku doesn't have a official builtpack for react.

Scroll down, click on Add Buildpacks and add

Enter fullscreen mode Exit fullscreen mode


Make sure they are in the right order as shown above.

Setting Config Vars

Config Vars

Go to Config Vars section and set up these two variables, PROJECT_PATH: frontend and REACT_APP_ALCHEMY_KEY: <YOUR_ALCHEMY_KEY>.


Now go to the deploy tab, here we have three different deployment methods. We will use the GitHub method. Click on it and it will ask you to connect to your github account.

Connect Github

Now, search for your github repo and click on connect.


Select your branch and Enable Automatic Deploys, this will enable continuous integration as and when you push new changes to your deployed branch.

After that click on Deploy Branch and we are done. We have now successfully deployed our project on heroku. Click on open app at the top to view your project.

I hope this tutorial series helped you understand things a little better and thank you for reading.
