DyanMoCo + MoCoQuery

DynamoDB is great but the way you interact with it is not really great. DynaMoco is small but mighty, wrapper that is strong enough to get what you want out of DynamoDB and gentle enough to act like bowling with bumpers on.

Writeen in Typescript it should help you with auto-complete etc - if that is of interest.

The DynaMoco Problem

1. The API of Dyanmo has a steep learning curve.
2. Its flexibiltiy creates too much complexity to comprehend at thge outset.
3. Dynamoco optimizes for a few use-cases that seem noramtive, making those very easy.
4. If you need to do the more complicated parts, it attempts to move out of the way.

The DynaMoco Solution

Use this package if:

• You need to just get going with DynamoDB
• You find the Dynamo API difficult and seemingly optimzed for AWS engineers and not it's users.
• You enjoy flexible streamlined modules.

Installation

npm install dynamoco
# or
yarn add dynamoco

Usage

There are two independent functions that work nicely together in dynamoco.

The first is the gentle wrapper - dynamoco

The second is a nice query builder - mocoquery

Each of them cover some ground on the API surface area exposed by Dyanmo.

Get Item (Full Monty)

import {Dynamo} from 'aws-sdk'
import {dynamoco} from 'dynamoco'
import {credentials} from './credentials'

;(async ()=>{
    const d = new Dyanmo({credentials})
    const moco = dynamoco(d)
    // using a table that is already available
    const resutls = await moco.getItem('MyTable', {MyKey: 'SomeValue'})
    console.log(results._Item) 
        /* {    
                MyKey: 'SomeValue', 
                numberValues: 1,
                stringValues: 'strings are strings'
            } 
        */
})()

Using The Query Builder

import {Dynamo} from 'aws-sdk'
import {mocoquery} from 'dynamoco'
import {credentials} from './credentials'

;(async ()=>{
    const d = new Dyanmo({credentials})
    const queryParams = mocoquery('MyTable')
                        .select('*')
                        .where(['Year','>=',2020])
                        .extract()
    // using the regular Dyanmo Client 
    const regularResults = await d.query(queryParams)
    console.log('regularResults', regularResults.Items)
    
    // using the regular Dyanmo Client 
    const ezResults = await dynamoco(d).query(queryParams)
    console.log('ezResults', ezResults._Items)
})()

Technical

Single dependency

By design, this module has a single, external, run-time dependency (aws-sdk). And it uses a few other packages while running tests. It is a stated goal of the project to keep the dependencies as small as reasonable. (different than as small as possible)

Dependency

• aws-sdk

Codebase

This is a Typescript codebase, and aims to be relatively up to date with the latest version. Adopting new typescript version will likely comence after some hardening period, but hastened if a new language feature has been added that substantially supports this project.

Roadmap

See the open issues for a list of proposed features (and known issues).
