Just a quick example I've thrown together for a blog post. This is aimed at giving you a feel how easy it is to get up and running with Fastify. For the sake of the example I've used Postgres.

Get set up with a .env file if you need to override the defaults:

PGUSER=myusername
PGPASSWORD=mypassword
PGDATABASE=mydatabase

Then run:

  npm i
  npm run dev  

I've used node 20 for this example.
