Deploying A Blitz Project

Deploy to Production

  1. You need a production Postgres database. Here's how to set this up on Digital Ocean.
  2. For deploying serverless, you also need a connection pool.
    1. Read the Digitial Ocean docs on setting up your connection pool
    2. Ensure you set your "Pool Mode" to be "Session" instead of "Transaction" (because of a bug in Prisma)
  3. Lastly, you need your entire database connection string. If you need, read the Prisma docs on this.
    1. If deploying to serverless with a connection pool, make sure you get the connection string to your connection pool, not directly to the DB.

Serverless

Assuming you already have a Zeit account and the now cli installed, you can do the following:

  1. Add your DB url as a secret environment variable by running now secrets add @database-url "DATABASE_CONNECTION_STRING"
  2. Add a now.json at your project root with
{
"env": {
"DATABASE_URL": "@database-url"
},
"build": {
"env": {
"DATABASE_URL": "@database-url"
}
}
}
  1. Run now

Once working and deployed to production, your app should be very stable because it’s running Next.js which is already battle tested.

Traditional, Long-Running Server

You can deploy a Blitz app like a regular Node or Express project.

blitz start --production will start your app in production mode. Make sure you provide the DATABASE_URL environment variable for your production database.
