So far as I could find, none of them discuss how to get Promise objects out of an SDK call. AWSJavaScriptSDK latest AWS DynamoDB DocumentClient.html.AWSJavaScriptSDK latest AWS DynamoDB.html.sdk-for-javascript v2 developer-guide/welcome.html.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. 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. And, by 8:30 PM this blog post was written. 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.īy 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 Let’s now start testing if everything works as expected.With the Serverless Framework it's possible to quickly implement Node.js Lambda functions using any AWS service. We already made all required adjustments.
Node.js how to connect to the local dynamodb Offline#
Function testingĪll other sources in this project look exactly the same as they would without using offline plugins, and therefore are not relevant for this article. With this mechanism, the endpoint used in local mode is different than in normal (“cloud”) mode, namely the one we defined in the serverless.yml file as environment variable CONFIG_DYNAMODB_ENDPOINT. You should at least know the basics of the Serverless framework and also have it installed.
Node.js how to connect to the local dynamodb code#
The idea behind it is simple: the code you execute locally is also executed in the cloud. If you already work with the Serverless framework, you can benefit from the variety of available offline plugins to get your cloud project up and running on your local machine. When the development environment is moved completely to a cloud provider, it usually takes more time and effort until a code change finally becomes visible in the product. Going serverless: How to move files from on-prem SFTP to AWS S3 demonstrates how to switch from FTP to cloud-based storageįor developers, new obstacles are emerging that have been less critical in classical approaches.The article Google Cloud Function for Machine Learning shows how to implement some cloud-based machine learning.Our blog contains a lot of great examples, maybe you want to have a look at these: There are many reasons for using cloud-based services. I will get an AWS stack up and running locally, based on Node.js, API Gateway, lambdas, and DynamoDB. I will provide an example reduced to the bare necessities, and will only go into detail on the relevant parts of the offline plugins. In this article, I will show you how to get started easily. You are using the Serverless framework on AWS? Did you know that you can develop on your local machine as well with little effort? For this purpose, a variety of Serverless offline plugins are available which make it possible to use services like Lambda, DynamoDB or S3 locally.
