Running it locally

  1. Make sure you have the latest version of Wasp installed by running curl -sSL https://get.wasp-lang.dev/installer.sh | sh in your terminal.
  2. Run wasp new <project-name> -t saas to create a new app using this template.
  3. Rename the env.server.example file to .env.server and fill in your API keys according to the instructions in the file.
  4. Make sure you have a Database connected and running. Here are two quick options:
  • run wasp start db if you have Docker installed and running (if not, on MacOS run brew install docker-machine docker then find and run the app from your launchpad). This will start a Postgres database for you. No need to do anything else! 🤯
  • or provision a Postgres database on Railway, go to settings and copy the connection url. Paste it as DATABASE_URL=<your-postgres-connection-url> into your env.server file.
  1. Run wasp db migrate-dev
  2. Run wasp start. This will install all dependencies and start the client and server for you :)
  3. Go to localhost:3000 in your browser (your NodeJS server will be running on port 3001)
  4. Install the Wasp extension for VSCode to get the best DX
  5. Check the files for comments containing specific instructions.
  6. If you would like to test Stripe Webhooks locally, download the Stripe CLI. This YouTube video does a great job explaining how to test webhooks locally with the Stripe CLI (watch until 27:00).
  7. Enjoy and Have fun. When you create an App with this template, be kind and let me know by tagging me on twitter @hot_town

Deploying it quickly to Fly.io

  1. Create an account on Fly.io
  2. Install the Fly CLI by running curl -L https://fly.io/install.sh | sh on Linux/MacOS
  3. Run wasp deploy fly setup my-wasp-app mia
  4. Run wasp deploy fly cmd secrets set ENV_VAR_EXAMPLE=<your-env-var> --context=server, making sure to fill in all of your env vars
  5. Run wasp deploy fly create-db mia
  6. Run wasp deploy fly deploy
  7. Make sure you've updated your Stripe webhook URL in your Stripe dashboard to point to your Fly app's URL
  8. Also make sure you've updated your Google Auth callback URL to point to your Fly app's URL

You can also see the guides for deploying manually to Fly, Railway, and Netlify here.

How it works

  • 🐝 Wasp - allows you to build full-stack apps with 10x less boilerplate
  • 🎨 Tailwind CSS - CSS that's easy to work with
  • 🤖 OpenAI - GPT-3.5 turbo API
  • 💸 Stripe - for payments
  • 📧 SendGrid - for email

Wasp as the full-stack framework allows you to describe your app’s core features in the main.wasp config file in the root directory. Then it builds and glues these features into a React-Express-Prisma app for you so that you can focus on writing the client and server-side logic instead of configuring. For example, I did not have to use any third-party libraries for Google Authentication. I just wrote a couple lines of code in the config file stating that I want to use Google Auth, and Wasp configures it for me. Check out the comments main.wasp file for more.

Stripe makes the payment functionality super easy. I just used their Subscription feature. After the user pays, their hasPaid and datePaid fields are updated in the database via the webhook found in the src/server/webhooks.ts file.

Wasp's integrated Jobs feature is used to run a cron job every week to send an newsletter email. I used SendGrid for the email service.
