## What it is
Dynamoose is a modeling tool for Amazon's DynamoDB, heavily inspired by Mongoose, providing a high-level, type-safe API for defining schemas and interacting with DynamoDB in Node.js. It supports features like strict data validation, transactions, conditional filtering, multi-region access, and DynamoDB Streams.

## Use cases
- model DynamoDB tables with schemas in Node.js
- validate and transform data before saving to DynamoDB
- run DynamoDB transactions with a high-level API
- query and filter DynamoDB items with a Mongoose-like syntax
- implement single table design in DynamoDB
- access DynamoDB across multiple AWS regions
- consume DynamoDB Streams in JavaScript

## When to choose
- you use DynamoDB from Node.js and want schema-based modeling
- you are familiar with Mongoose and want similar ergonomics for DynamoDB
- you need strict validation, transactions, or multi-region support for DynamoDB

## When to avoid
- you use a relational database instead of DynamoDB
- you prefer raw AWS SDK control over DynamoDB requests
- your project is not JavaScript/TypeScript on Node.js
