Step-by-step setup

When deploying this template, the sequence of steps is important. Follow the steps below in order to get up and running.

Configure Auth

Follow this guide to set up an OAuth app with GitHub and configure Supabase to use it as an auth provider.

In your Supabase project, navigate to auth > URL configuration and set your main production URL (e.g. https://your-deployment-url.vercel.app) as the site url.

Next, in your Vercel deployment settings, add a new Production environment variable called NEXT_PUBLIC_SITE_URL and set it to the same URL. Make sure to deselect preview and development environments to make sure that preview branches and local development work correctly.

Develop locally

If you haven't already done so, clone your Github repository to your local machine.

Install dependencies

Ensure you have pnpm installed and run:

pnpm install

Local development with Supabase

It's highly recommended to use a local Supabase instance for development and testing. We have provided a set of custom commands for this in package.json.

First, you will need to install Docker. You should also copy or rename:

.env.local.example -> .env.local
.env.example -> .env

Next, run the following command to start a local Supabase instance and run the migrations to set up the database schema:

pnpm supabase:start

The terminal output will provide you with URLs to access the different services within the Supabase stack. The Supabase Studio is where you can make changes to your local database instance.

Copy the value for the service_role_key and paste it as the value for the SUPABASE_SERVICE_ROLE_KEY in your .env.local file.

You can print out these URLs at any time with the following command:

pnpm supabase:status

To link your local Supabase instance to your project, run the following command, navigate to the Supabase project you created above, and enter your database password.

pnpm supabase:link

If you need to reset your database password, head over to your database settings and click "Reset database password", and this time copy it across to a password manager! 😄

🚧 Warning: This links our Local Development instance to the project we are using for production. Currently, it only has test records, but once it has customer data, we recommend using Branching or manually creating a separate preview or staging environment, to ensure your customer's data is not used locally, and schema changes/migrations can be thoroughly tested before shipping to production.

Once you've linked your project, you can pull down any schema changes you made in your remote database with:

pnpm supabase:pull

You can seed your local database with any data you added in your remote database with:

pnpm supabase:generate-seed
pnpm supabase:reset

🚧 Warning: this is seeding data from the production database. Currently, this only contains test data, but we recommend using Branching or manually setting up a preview or staging environment once this contains real customer data.

You can make changes to the database schema in your local Supabase Studio and run the following command to generate TypeScript types to match your schema:

pnpm supabase:generate-types

You can also automatically generate a migration file with all the changes you've made to your local database schema with the following command:

pnpm supabase:generate-migration

And push those changes to your remote database with:

pnpm supabase:push

Remember to test your changes thoroughly in your local and staging or preview environments before deploying them to production!

Use the Stripe CLI to test webhooks

Use the Stripe CLI to login to your Stripe account:

pnpm stripe:login

This will print a URL to navigate to in your browser and provide access to your Stripe account.

Next, start local webhook forwarding:

pnpm stripe:listen

Running this Stripe command will print a webhook secret (such as, whsec_***) to the console. Set STRIPE_WEBHOOK_SECRET to this value in your .env.local file. If you haven't already, you should also set NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY and STRIPE_SECRET_KEY in your .env.local file using the test mode(!) keys from your Stripe dashboard.

Run the Next.js client

In a separate terminal, run the following command to start the development server:

pnpm dev

Note that webhook forwarding and the development server must be running concurrently in two separate terminals for the application to work correctly.

Finally, navigate to http://localhost:3000 in your browser to see the application rendered.

Going live

Archive testing products

Archive all test mode Stripe products before going live. Before creating your live mode products, make sure to follow the steps below to set up your live mode env vars and webhooks.

Configure production environment variables

To run the project in live mode and process payments with Stripe, switch Stripe from "test mode" to "production mode." Your Stripe API keys will be different in production mode, and you will have to create a separate production mode webhook. Copy these values and paste them into Vercel, replacing the test mode values.

Redeploy

Afterward, you will need to rebuild your production deployment for the changes to take effect. Within your project Dashboard, navigate to the "Deployments" tab, select the most recent deployment, click the overflow menu button (next to the "Visit" button) and select "Redeploy" (do NOT enable the "Use existing Build Cache" option).

To verify you are running in production mode, test checking out with the Stripe test card. The test card should not work.
