«Hello World» tutorial demo
Hello World
This is a minimal Sails program that returns the classic "hello world" greeting.
Sails lets you organize a program into services and expose methods that users and applications can call. This example defines a service named HelloWorld.
Build the program into WebAssembly, then deploy it to Vara before sending messages to its service methods.
Deployments and state-changing messages use gas. You can develop and test locally before uploading the program to a network.
The tutorials cover the full workflow: project setup, program logic, testing, deployment, and frontend integration.
A simple interaction
Services can expose queries like greeting(). Getters are special external interface functions that allow users to query information from the contract. Try to call the getter by pressing the Run button. Calling getters is free and does not cost gas.
