# I built a type-safe SQL library for Bun — no ORM, no codegen, just SQL (using Claude Code)

I've been using Bun for a while and kept running into the same problem: every SQL library either requires Node.js internals, leans heavily on an ORM abstraction I don't want, or generates types from a schema file at build time.

So I built squn — a lightweight, type-safe SQL query library that works natively with Bun's built-in database clients.

The core idea

Every query goes through a tagged template literal called sql. Interpolated values always become bound parameters — they are never concatenated into the SQL string. SQL injection is structurally impossible by design.

import { createDb, PostgresAdapter, sql } from "@phonemyatt/squn";
