SafeQL

SafeQL is an ESLint plugin for TypeScript developers that analyzes raw SQL query strings in your code. It checks your queries for syntax errors and, more importantly, automatically infers the exact TypeScript types for the data those queries will return. This means you get compile-time type safety for your database operations, catching potential bugs before they ever reach your database.

The tool works by statically analyzing your code to find SQL template literals. It then connects to your actual database to understand your schema and validates that your queries are syntactically correct. It generates precise TypeScript interfaces for your query results, making the return data fully typed. It's designed to be database client-agnostic, working with popular PostgreSQL libraries like Prisma, Sequelize, pg, and Postgres.js.

This is a major productivity boost for backend developers and full-stack engineers working with TypeScript and PostgreSQL. It eliminates a whole class of runtime errors related to malformed SQL or incorrectly typed query results. If you've ever been frustrated by a typo in a column name that only shows up at runtime, or spent time manually defining types for database responses, SafeQL automates that safety net directly into your development workflow.
