If you are using Typescript, dynamo-easy might be a good option. Just add some decorators to your model and start using it.

import { Model, PartitionKey, DynamoStore } from '@shiftcoders/dynamo-easy'

@Model()
export class Person {
  @PartitionKey()
  id: string
  name: string
  yearOfBirth: number
}

const personStore = new DynamoStore(Person)

personStore
  .scan()
  .whereAttribute('yearOfBirth').equals(1958)
  .exec()
  .then(res => console.log('ALL items with yearOfBirth == 1958', res))

It uses the AWS DynamoDB sdk but takes care of the mapping between JS and DynamoDB types and provides a simple to use fluent API.
