## What it is
PgTyped is a TypeScript library that generates static types for raw SQL queries against a running PostgreSQL database. It parses queries from SQL or TS files and produces typed query functions without requiring schema definitions or acting as an ORM.

## Use cases
- generate TypeScript types for raw SQL queries
- use raw SQL with type safety in a Node.js app
- avoid writing an ORM schema mapping for Postgres
- prevent SQL injection when writing parameterized queries
- auto-generate query result and parameter interfaces from a live Postgres database
- write SQL in .sql files and get typed query functions

## When to choose
- you prefer writing raw SQL over query builders or ORMs
- you want compile-time type checking of query parameters and results
- your team uses PostgreSQL with TypeScript and wants minimal runtime overhead
- you want the live database schema to be the source of truth for types

## When to avoid
- you need an ORM with relations, migrations, and schema management
- you use a database other than PostgreSQL
- you don't want a running database connection during development for type generation
- you need runtime query building or dynamic SQL composition
