Getting Started for Developers

Here's a video on how to set up the project. It covers the same steps mentioned in this document. But goes into greater detail on setting up the external services.

The external services that are required are:

We use Postgres for the database.

You can run Postgres & Redis locally using docker-compose

docker-compose up -d # -d will run the services in the background

Create your own .env file:

cp apps/web/.env.example apps/web/.env
cd apps/web
pnpm install

Set the environment variables in the newly created .env. You can see a list of required variables in: apps/web/env.ts.

The required environment variables:

  • NEXTAUTH_SECRET -- can be any random string (try using openssl rand -hex 32 for a quick secure random string)
  • GOOGLE_CLIENT_ID -- Google OAuth client ID. More info here
  • GOOGLE_CLIENT_SECRET -- Google OAuth client secret. More info here
  • OPENAI_API_KEY -- OpenAI API key.
  • UPSTASH_REDIS_URL -- Redis URL from Upstash.
  • UPSTASH_REDIS_TOKEN -- Redis token from Upstash.
  • TINYBIRD_TOKEN -- Admin token for your Tinybird workspace (be sure to create an instance in the GCP us-east4 region. This can also be changed via your .env if you prefer a different region). You can also decide to disabled Tinybird and then the analytics and bulk unsubscribe features will be disabled. Set NEXT_PUBLIC_DISABLE_TINYBIRD=true if you decide to disable Tinybird.

To run the migrations:

pnpm prisma migrate dev

To run the app locally:

pnpm run dev

Or from the project root:

turbo dev

Open http://localhost:3000 to view it in your browser. To upgrade yourself to admin visit: http://localhost:3000/admin.

Setting up Google OAuth and Gmail API

You need to enable these scopes in the Google Cloud Console:

Setting up Tinybird

Follow the instructions here to setup the pipes and datasources.

Optional: If you want to store AI usage stats in Tinybird too, then do the same in /packages/tinybird-ai-analytics.

Set up push notifications via Google PubSub to handle emails in real time

Follow instructions here.

  1. Create a topic
  2. Create a subscription
  3. Grant publish rights on your topic

Set env var GOOGLE_PUBSUB_TOPIC_NAME. When creating the subscription select Push and the url should look something like: or where the domain is your domain. Set GOOGLE_PUBSUB_VERIFICATION_TOKEN in your .env file to be the value of TOKEN.

To run in development ngrok can be helpful:

ngrok http 3000

And then update the webhook endpoint in the Google PubSub subscriptions dashboard.
