## What it is
Deepkit is a modular, high-performance TypeScript framework that preserves TypeScript types at runtime via a compiler plugin, enabling validation, serialization, ORM, HTTP, RPC, and dependency injection from a single type definition. It ships as 40+ independent packages including an ORM, HTTP/RPC servers, broker, and filesystem abstractions.

## Use cases
- build a type-safe backend web application in TypeScript
- avoid duplicating types as Zod schemas and ORM entities
- validate and serialize data from TypeScript types at runtime
- define a type-first ORM schema for Postgres, MySQL, SQLite, or MongoDB
- set up type-safe binary RPC over WebSockets or TCP
- add pub/sub, queues, caching, and distributed locks via a broker abstraction
- build CLI tools with automatic argument validation and DI
- serve an Angular SSR application with a Deepkit backend

## When to choose
- you want one TypeScript type definition to drive validation, serialization, database, and API layers
- you need a full-stack enterprise backend framework comparable to Spring or Laravel but in TypeScript
- performance matters and you want JIT-compiled validation and serialization
- you prefer modular packages you can adopt incrementally

## When to avoid
- your project is plain JavaScript without a TypeScript build step
- you need a framework with a much larger ecosystem and community than Deepkit
- you cannot adopt a custom compiler transform in your build pipeline
- you only need a minimal HTTP router without runtime types
