Introducing TypoKit

We’re excited to introduce TypoKit — an AI-native, schema-first TypeScript API framework built for the next generation of backend development.

Why TypoKit?

Modern API development demands more than just a request handler. Teams need type safety from database to client, performance that scales, and tooling that works with AI coding assistants — not against them.

TypoKit was designed from the ground up to address these challenges:

Schema-First Types — Define your API schema once and get TypeScript types, runtime validation (via Typia), OpenAPI specs, and client SDKs generated automatically.
Rust Build Pipeline — A high-performance native transform pipeline powered by napi-rs processes your schemas in milliseconds, not seconds.
AI-Native Architecture — File-per-concern layout, structured error output, and machine-readable inspection commands make TypoKit the ideal framework for AI-assisted development.

Schema-First by Design

At the heart of TypoKit is a simple idea: your TypeScript types are the single source of truth. Define a type, and the build pipeline generates everything else:

// types/User.ts — this is all you write
export interface User {
  id: string;
  name: string;
  email: string;
  createdAt: Date;
}

From this single definition, TypoKit generates:

Runtime validators with detailed error messages
OpenAPI 3.1 schema definitions
Type-safe route handlers with full IntelliSense
Test stubs and fixtures
Client SDK types

The Rust Advantage

TypoKit’s build pipeline isn’t just fast — it’s native-speed fast. By leveraging Rust via napi-rs, the transform pipeline processes your entire API schema in a fraction of the time traditional TypeScript tooling requires.

The build pipeline flows through well-defined stages — parse, extract, route table generation, OpenAPI generation, and more — each orchestrated through a tapable hook system that plugins can extend.

Bring Your Own Stack

TypoKit adapts to your infrastructure, not the other way around:

Server Adapters — Run on Express, Fastify, Hono, or the built-in native HTTP server
Platform Adapters — Deploy to Node.js, Bun, or Deno
Database Adapters — Connect with Drizzle, Kysely, Prisma, or raw SQL
Plugin System — Extend TypoKit with WebSocket support, debug tooling, and custom plugins

What’s Next

We’re just getting started. Here’s what’s on the roadmap:

More client generators — React Query and SWR adapters are available today, with more coming
Enhanced AI tooling — Deeper integration with coding assistants through structured output and llms.txt
Performance benchmarks — Detailed comparisons showing TypoKit’s compiled router performance
Community plugins — A growing ecosystem of community-built plugins
