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

Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults and a great developer experience. The key features include:

  • TypeScript out of the box: First-class support for TypeScript – no need to spend hours configuring things that break as soon as you update a dependency.
  • Great all-in-one tooling: Built-in linter, code formatter, ability to build a self-contained executable, test runner, IDE integration, and more.

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

  1. Fork the following GitHub 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


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.
