Backend Deployment

Genezio offers a seamless and efficient solution for deploying backend logic. The platform leverages a function-as-a-service infrastructure, allowing users to deploy their backend classes easily with a simple command: genezio deploy.


You can deploy classes written in TypeScript, JavaScript, and Dart (experimental).

Code Structure

To deploy with genezio, your code has to be structured in classes. Mark your classes for deployment with the GenezioDeploy decorator. This decorator also enables you to set the default type of the methods implemented in the specific class to jsonrpc, http or cron.


Our recommendation is to use the official genezio templates and examples to be provided with fully written configuration files without having to write one from scratch.

Check out this tutorial to learn how to create-your-first-project with genezio.

A snippet of a class that can be deployed with genezio is below:

import { GenezioDeploy } from "@genezio/types";

export class HelloWorldService {
hello(name: string, sender: string): string {
`Hello world request received with name ${name} from ${sender}!`
return `Hello, ${name}, from ${sender}!`;

Configuration file

To deploy your code, your project needs a minimum configuration file that sets various configurations for the project such as name, region to deploy to, and so on. A minimum genezio.yaml to deploy a project should look like this:

name: my-project-backend
region: us-east-1
language: ts
cloudProvider: genezio
packageManager: npm

For more details on the genezio.yaml file, check the genezio-configuration-file section.


For Dart backend code, a classes list should also be set in the genezio.yaml. Check the classes section from #configuration-file for more information.

Deploy your project

The command to deploy has to be executed at the same path where genezio.yamlis saved:

genezio deploy

Executing genezio deploy will deploy the HelloWorldServiceclass implemented in the snippet above.


webhooks You can make requests to the remote server either by using the testing functionality from the genezio dashboard, or by using a client application - such as a React app.

To call the methods implemented in the HelloWorldService, you can make use of the genezio generated SDK for your project. Check generated-sdk section to find out how to install it in your project.

Now let's see how to schedule the execution of a function as a cron job, or implement HTTP Webhooks:
