## What it is
DynamoDB-Toolbox is a lightweight, type-safe query builder and abstraction layer over the AWS DynamoDB Document Client for TypeScript. It provides rich schema definitions with validation, defaults, and portability to Zod/JSON Schema, with strong support for single-table designs.

## Use cases
- build type-safe DynamoDB queries in TypeScript
- validate items pushed to and fetched from DynamoDB against schemas
- implement single-table design patterns in DynamoDB
- replace the awkward AWS Document Client with a friendlier API
- share schemas between Zod, JSON Schema, and DynamoDB
- keep serverless bundle sizes small with a tree-shakable DynamoDB library

## When to choose
- you use DynamoDB with TypeScript and want end-to-end type safety
- you need schema validation and defaults for DynamoDB items
- you're building serverless applications on AWS with DynamoDB
- you query multiple entities from a single DynamoDB table

## When to avoid
- you use a relational or non-AWS database
- you want a full ORM with migrations and joins rather than a query builder
- your project doesn't use TypeScript and you don't need type safety

## Facets
- artifact type: library
