Summary: Connect a Lakebase Postgres database to a Koyeb-deployed Node.js application using Prisma as the ORM and a DATABASE_URL environment variable. Use this guide when you need a managed Postgres backend on Koyeb without running your own database server. Covers both the Koyeb control panel and CLI deployment paths, including Prisma schema sync and database seeding.

Learn how to connect a Lakebase Postgres database to an application deployed with Koyeb

Koyeb is a developer-friendly, serverless platform designed to easily deploy reliable and scalable applications globally. Koyeb offers native autoscaling, automatic HTTPS (SSL), auto-healing, and global load-balancing across their edge network with zero configuration.

This guide describes how connect a Lakebase Postgres database to an application deployed with Koyeb. To follow the instructions in this guide, you require:

• A Koyeb account to deploy the application. Alternatively, you can install the Koyeb CLI if you prefer to deploy the application from your terminal.
• A Neon account to deploy the Postgres database. If you do not have one, see Sign up.

The example application connects to your database using Prisma as an ORM. Prisma synchronizes the database schema with the Prisma schema included with the application and seeds the database.

1. Navigate to the Neon Console.
2. Select Create a project.
3. Enter a name for the project (neon-koyeb, for example), and select a Postgres version and region.
4. Click Create project.

A dialog pops up with your Neon connection string, which appears similar to the following:

postgresql://[user]:[password]@[neon_hostname]/[dbname]

Store this value in a safe place. It is required later. The connection string specifies neondb as the database. This is the database created with your Neon project if you did not specify a different database name. You will use this database with the example application.

You can deploy on Koyeb using the control panel or the Koyeb CLI.

To deploy the application from the Koyeb control panel, follow these steps:

1. Navigate to the Apps tab and select Create App.
2. Select GitHub as the deployment method.
3. When asked to select the repository to deploy, enter https://github.com/koyeb/example-express-prisma in the Public GitHub repository field.
4. Keep example-express-prisma as the name and main as the branch.
5. In Build and deployment settings, enable the Override setting and add the following Build command: npm run postgres:init
6. Select the region closest to your Neon database.
7. Under Advanced > Environment variables, add a DATABASE_URL environment variable to enable the application to connect to your database on Neon. Set the value to the Neon connection string provided to you when you created the Neon project.
8. Enter a name for your app. For example, express-neon
9. Click Deploy.

Koyeb builds the application. After the build and deployment have finished, you can access your application running on Koyeb by clicking the URL ending with .koyeb.app.

The example application exposes a /planets endpoint that you can use to list planets from the database. After your deployment is live, you should see the following results when navigating to https://<YOUR_APP_URL>.koyeb.app/planets:

[
  {
    "id": 1,
    "name": "Mercury"
  },
  {
    "id": 2,
    "name": "Venus"
  },
  {
    "id": 3,
    "name": "Mars"
  }
]

You can also deploy your application using the Koyeb CLI. To install it, follow the instructions in the Koyeb CLI documentation.

Using the CLI requires an API access token, which you can generate in the Koyeb control panel, under Organization Settings > API. Once generated, run the command koyeb login and enter the token when prompted.

To deploy the example application, run the following command in your terminal. Make sure to replace the DATABASE_URL with your Neon connection string.

koyeb apps init express-neon \
--instance-type free \
--git github.com/koyeb/example-express-prisma \
--git-branch main \
--git-build-command "npm run postgres:init" \
--ports 8080:http \
--routes /:8080 \
--env PORT=8080 \
--env DATABASE_URL="{}"

To track the app deployment and visualize build logs, execute the following command:

koyeb service logs express-neon/express-neon -t build

After the build and deployment have finished, you can retrieve the public domain to access your application by running the following command:

$ koyeb app get express-neon
ID          NAME         STATUS         DOMAINS                                CREATED AT
b8611a1d    express-neon HEALTHY        ["express-neon-myorg.koyeb.app"]       16 Feb 23 18:13 UTC

The example application exposes a /planets endpoint that you can use to list planets from the database. After your deployment is live, you should see the following results when navigating to https://<YOUR_APP_URL>.koyeb.app/planets:

[
  {
    "id": 1,
    "name": "Mercury"
  },
  {
    "id": 2,
    "name": "Venus"
  },
  {
    "id": 3,
    "name": "Mars"
  }
]

To delete the example application on Koyeb to avoid incurring any charges, follow these steps:

1. From the Koyeb control panel, select the App to delete.
2. On the Settings tab, select Danger Zone and click Delete.

To delete your Neon project, refer to Delete a project.
