## What it is
Zapatos is a TypeScript library providing zero-abstraction, fully typed access to Postgres. It generates a TypeScript schema from your database and offers typed helpers for arbitrary SQL, CRUD, nested LATERAL JOINs, and transactions.

## Use cases
- write type-safe SQL queries in TypeScript against Postgres
- generate TypeScript types from a Postgres schema
- run typed CRUD queries without an ORM
- build nested JSON results from LATERAL JOINs
- manage and retry Postgres transactions in TypeScript
- avoid ORM abstractions while keeping type safety

## When to choose
- you know SQL and want Postgres-first, type-safe queries in TypeScript
- you want automatic types generated from your actual database schema
- you need complex nested JSON query results without an ORM
- you find traditional ORMs too heavy or leaky

## When to avoid
- you need multi-database support beyond Postgres
- you want a full ORM with migrations, models, and change tracking
- your project is not TypeScript or JavaScript with type checking
- you prefer query-builder abstractions over raw SQL

## Facets
