Getting started with Neon and Cloudflare Workers

This is the code repository for the guide on how to deploy a Cloudflare worker application using Neon. Follow the guide to set up the Neon project and your Cloudflare application.

Store your Neon credentials

Run the command below to copy the .env.example file to a .dev.vars file in the code directory:

cp .env.example my-neon-worker/.dev.vars

Store your Neon credentials in this .dev.vars file.

DATABASE_URL="postgresql://neondb_owner:[email protected]/neondb?sslmode=require"
  • user is the database user.
  • password is the database user’s password.
  • endpoint_hostname is the host with neon.tech as the TLD.
  • dbname is the name of the database. “neondb” is the default database created with each Neon project.
  • ?sslmode=require an optional query parameter that enforces the SSL mode while connecting to the Postgres instance for better security.

Important: To ensure the security of your data, never expose your Neon credentials to the browser.

Test the application locally

Navigate to the my-neon-worker directory, and install the dependencies:

cd my-neon-worker && npm install

Now, run the command below to deploy the application locally:

npx wrangler dev

Deploy the application to Cloudflare platform

Follow the guide for instructions on how to deploy the application to the Cloudflare Workers platform. Make sure to add the Neon connection string as a secret to your Worker application.
