Sruja Cheatsheet

Elements

import { * } from 'sruja.ai/stdlib'

User = person "User"
App = system "App" {
    Web = container "Web"
    API = container "API"
    DB = database "DB"
}
User -> App.Web "Uses"
App.Web -> App.API "Calls"
App.API -> App.DB "Reads/Writes"

view index {
    include *
}

Tip

The import { * } from 'sruja.ai/stdlib' line provides all standard kinds. You can also declare kinds manually if needed: person = kind "Person", system = kind "System", etc.

import { * } from 'sruja.ai/stdlib'

App = system "App" {
    Web = container "Web" {
        Cart = component "Cart"
    }
}

Scenario

import { * } from 'sruja.ai/stdlib'

User = person "User"

App = system "App" {
    Web = container "Web"
    API = container "API"
    DB = database "Database"
}

scenario Checkout "Checkout Flow" {
    User -> App.Web "adds items"
    App.Web -> App.API "validates"
    App.API -> App.DB "stores order"
}
