## What it is
Slonik is a Node.js PostgreSQL client library written in TypeScript that emphasizes writing raw SQL with strict runtime validation and build-time type safety. It provides safe connection and transaction handling, query retrying, interceptors, and detailed logging.

## Use cases
- query postgres from nodejs with type safety
- write raw sql queries safely in typescript
- manage postgres connection pools and transactions
- prevent sql injection with safe value interpolation
- add logging and interceptors to database queries
- retry failed queries and transactions automatically

## When to choose
- you prefer writing raw SQL over query builders or ORMs
- you want runtime validation of query results in TypeScript
- you need robust transaction and connection pool handling
- you want detailed query logging and debugging

## When to avoid
- you want an ORM with automatic schema-to-object mapping
- you need dynamic SQL generation like Knex.js
- you are not using Node.js or PostgreSQL
