Kite Language Quick Reference

// Imports
import * from "common.kite"
import ServerConfig from "configs.kite"

// Type alias
type Environment = "dev" | "staging" | "prod"

// Schema definition
schema ServerConfig {
  string   host     = "localhost"
  number   port     = 8080
  boolean  ssl      = true
  string[] tags
}

// Resource instantiation
@provider("aws")
@tags({Environment: "production"})
resource ServerConfig webServer {
  host = "api.example.com"
  port = 443
  ssl  = true
  tags = ["web", "production"]
}

// Component definition
component WebServer {
  input string name = "default"
  input number replicas = 1
  output string endpoint = "http://${name}.example.com"
}

// Component instantiation
component WebServer api {
  name = "payments"
  replicas = 3
}

// Variables
var region = "us-east-1"
var cost = calculateCost(5, "production")
