Define a data model. Get a full API. Scale to events, realtime, auth, permissions, and jobs.
Quick Start Composing an App Examples

Hello, world

Section titled “Hello, world”
app.config.ts
import { defineApp, defineEntity, definePackage, entity, field } from '@lastshotlabs/slingshot';


const Task = defineEntity('Task', {
  namespace: 'app',
  fields: {
    id: field.string({ primary: true, default: 'uuid' }),
    title: field.string(),
    done: field.boolean({ default: false }),
  },
});


export default defineApp({
  port: 3000,
  packages: [definePackage({ name: 'app', entities: [entity({ config: Task })] })],
});

Five routes, request validation, OpenAPI docs, and swappable storage — from one definition.

What are you building?

Section titled “What are you building?”
Quick Start Paste, run, curl, done. A route, an entity, and auth in 3 steps.
I need a feature Data, events, realtime, auth, permissions, or jobs — pick one, get working code.
I want complete app examples SaaS, forum, collaboration, content platform, game engine — find your use case.
I want to understand the model How app roots, packages, and entities fit together.

What you get

Section titled “What you get”

Generated CRUD

Define a model with defineEntity. Get GET, POST, PATCH, DELETE routes with validation and OpenAPI docs.

Operations

Add domain actions like publish, archive, complete alongside CRUD. Each generates a typed, documented route.

Events and the Event Bus

One event triggers many effects — welcome email, search index, admin notification. No coupling between packages.

Realtime

SSE for live updates. WebSockets for chat and collaboration. Both built in.

Auth and Permissions

Sessions, OAuth, MFA, passkeys, RBAC, and resource-level access control.

Swappable Storage

Memory for dev, SQLite for prototyping, Postgres for production. Same entity code.
