This is an example of how to set up a Deno application to deploy on Kinsta’s Application Hosting services from a GitHub repository.

Deno is a JavaScript, TypeScript, and WebAssembly runtime that allows you to run code outside of a web browser that allows you to build secure server-side applications. More information is available at the Deno website.

During the deployment process, Kinsta automatically installs dependencies defined in your package.json file.

  1. Log in to GitHub and create a new repository from this template (Use this template > Create a new repository): Kinsta – Hello World – Deno.
  2. In MyKinsta, add an application with the Hello World – Deno. The Start command can be left blank for the web process as Kinsta automatically detects the required command during the first deployment.

The app is available as soon as the build finishes, and a Hello World page loads at your application’s URL.

Web Server Setup

Port

Kinsta automatically sets the PORT environment variable. You do not need to define it or hard-code it into the application.

Start Command

When you deploy the application, Kinsta automatically creates a web process with npm start as the Start command.

Deployment Lifecycle

Whenever a deployment is initiated (through creating an application or re-deploying due to an incoming commit), the npm build command is run, followed by the npm start command.
