Deploying a class with genezio

The main unit of deployment in Typescript is a class. The methods of your class can be called using the following ways:
Below we can see a basic example of a Typescript class deployed using genezio.
// hello.ts
export enum Season {
Winter = "Winter",
Summer = "Summer"
export class HelloWorld {
constructor() {
console.log("Constructor called!")
helloWorld() {
return "Hello world!";
hello(name: string, from: string, value: Season): string {
const message = `Hello, ${name}, from ${from} during this ${value}`;
return message

Supported types

The following types are supported as parameters or return types:
  • number
  • String
  • enums
  • classes
  • typedefs
We currently don't support importing classes and enums from other files. If you want to use a custom type as a method's parameter or return type, it has to be declared in the same file.
If you don't have any tsconfig.json next to your classes, genezio CLI will generate one for you.

Genezio configuration file

To deploy this class, you also need a genezio.yaml configuration file. Learn more about which configuration fields you can tweak.
# genezio.yaml
name: hello-world
region: us-east-1
language: ts
runtime: node
path: ../client/sdk/
- path: ./hello.ts
type: jsonrpc
