## What it is
Pongo is a TypeScript library that provides a MongoDB-compatible document API backed by PostgreSQL, offering strong consistency guarantees. It supports both a typed Pongo client and a MongoDB-compliant shim so existing Mongo-style code can run on Postgres.

## Use cases
- use MongoDB syntax but store data in PostgreSQL
- migrate a Node.js app from MongoDB to Postgres without rewriting queries
- get strong consistency guarantees for document storage
- store JSON documents in Postgres with typed collections
- replace MongoDB with an existing Postgres infrastructure

## When to choose
- you want Mongo-like developer experience with PostgreSQL reliability
- your team already runs Postgres and wants document-style queries
- you need strong consistency that MongoDB deployments may not provide
- you want TypeScript-typed document collections

## When to avoid
- you need MongoDB-specific features like replica sets, sharding, or aggregation pipelines beyond the supported subset
- you want a pure document database without operating Postgres
- your project is not on Node.js/TypeScript
