Environment Variables

That that we have our project cloned, and database set up, we need to set up our environment variables. To do this, we will need to create a .env file in the root of our project.


To retrieve the Supabase variables, we can run the following command in our terminal:

supabase status
Supabase must be running in order for this command to work.

This will return a list of urls and keys about our project. We will need to add the following variables to our .env file:


Github OAuth

For local authentication we will be using GitHub. To set this up, we will need to create a GitHub OAuth app. Go to your GitHub settings and click on “Developer Settings” in the sidebar. Then click on “OAuth Apps” and “New OAuth App”. Fill out the form with the following information:

  • Application Name: Development
  • Homepage URL: http://localhost:3000
  • Authorization callback URL:

Once you have created the app, you will be given a Client ID and Client Secret. Add these to your .env file:

GITHUB_CLIENT_ID= # client id
GITHUB_CLIENT_SECRET= # client secret


This is optional. If you do not need to send emails, you can skip this step.

To send emails, we will be using Resend. Create an account and add your API key to your .env file:

RESEND_API_KEY= # api key


We will also need to add one other variables to our .env file:

NEXT_PUBLIC_ROOT_DOMAIN= # root domain (e.g. localhost:3000)

Next Steps

Now that we have everything set up, we are ready to start the development server and begin building.

pnpm dev
