Also since we'll be using Serverless Framework to deploy our cloudformation stack, i assume that you already have installed and set up the programmatic access to your AWS account with Serverless.

Under our root folder, we'll create a folder called resources which will contain a file called dynamo-table.yml containing our code for creating DynamoDB table.

We'll call our root-folder DynamoCRUD, however feel free to call it anything you like. To kick off, we first have to define the following file structure: In this article, we'll perform basic CRUD operations using AWS Lambda and NodeJS. So from the definition, it is clear that DynamoDB is a serverless, fully-managed millisecond performance and highly scalable NoSQL database which was announced in Early 2012. I exposed needed ports and I add needed environment variables but I keep having this error: Error: connect ECONNREFUSED 127.0.0.1:8000 at TCPConnectWrap. It works with nodemon but not with 2 containers. It's a fully managed, multiregion, multimaster, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications'. Im tryng to setup a local environment with node and dynamoDB, but I cant connect inside my app container to DynamoDB container. But there is a simple workaround - wrap the function inside an await new Promise construct.AWS defines DynamoDB as 'Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. Since we all should be doing our best to use async/await functions, and to use functions that return Promise objects, having an SDK lacking support for Promises is inconvenient. So far as I could find, none of them discuss how to get Promise objects out of an SDK call.

There are three places this SDK is documented:

Supposedly, AWS SDK for JavaScript does not support Promises Namely - how to get a Promise out of AWS SDK for JavaScript method calls. Run a DynamoDB instance locally with Node.js dynamodb node aws database Node.js + MongoDB is extremely popular when you need a fast and convenient development cycle but dont need to care much about the performance even though MongoDB is quite performant. That's pretty impressive, but it is also a tangent from what we're here to do.

Plus did some other futzing around doing unrelated stuff on Facebook/Quora/YouTube.

Serverless is great, but articles sometimes sound more like a TV commercial. And, by 8:30 PM this blog post was written. There are many articles on serverless with explained ideas, benefits and so on. In other words - in about 2 hours I did rewrote one application, and then wrote a whole new Serverless Framework application. Why await new Promise? Why not just query DynamoDB using promises in the first place instead of callbacks? Good article, but the example snippets could have been better.Д«y 7:40 PM I'd read the response, had an initial response ('because the SDK doesn't support that'), then thought it would be better to see if it does support it, found the announcement that the AWS SDK for Node.js does support Promise's, digested in my mind how to implement the support in my application, updated the application for the article, tested that implementation, updated the article, then read a few posts on Quora, watched a could YouTube videos, then thought I might write this blog post, wrote a quick sample application, and debugged that application. In this case at 5:30 PM I received email notification that a reader had replied to the newly posted article on the Sourcerer blog saying:

For a simple example, see Getting started with using Node.js and the Serverless framework on AWS Lambda Access aws dynamo db from javascript/nodejs and perform CRUD operation (read/write) in dynamo db table.Js files. With the Serverless Framework it's possible to quickly implement Node.js Lambda functions using any AWS service.
