DynamoDB-Toolbox v2 Patterns (TypeScript)

Overview

This skill provides practical TypeScript patterns for using DynamoDB-Toolbox v2 with AWS SDK v3 DocumentClient. It focuses on type-safe schema modeling, .build() command usage, and production-ready single-table design.

When to Use

  • Defining DynamoDB tables and entities with strict TypeScript inference
  • Modeling schemas with item, string, number, list, set, map, and record
  • Implementing GetItem, PutItem, UpdateItem, DeleteItem via .build()
  • Building query and scan access paths with primary keys and GSIs
  • Handling batch and transactional operations
  • Designing single-table systems with computed keys and entity patterns

Instructions

  1. Start from access patterns: identify read/write queries first, then design keys.
  2. Create table + entity boundaries: one table, multiple entities if using single-table design.
