Dynamometer

A library to easily work with DynamoDB and enforces single table design approach.

Introduction

Inspired by Firestore SDK.

Managing your data with a single design approach in DynamodDB can sometimes be difficult. Dynamometer uses so-called " Collections" and "Docs" to structure your data in an comprehensible way.

const db = Dynamometer.create({
  tableName: "dataTable"
})
Dynamometer is intended for simple, low-complexity projects and is designed to allow an architect to immediately take a
single-table approach with a DynamoDB table without having to think much about access patterns.

db.collection('USERS')
  .doc("xspvLRiJ")
  .collection("TODOS")
  .add({
    text: "Makes managing your data a breeze."
  })
