How to Create a Serverless NodeJS REST API
A guide for creating a REST API with the Serverless Framework and DynamoDB
Interested in how to quickly build manageable serverless REST APIs? In this article, I will be demonstrating how to accomplish this for NodeJS REST APIs with the Serverless Framework. For this demonstration, we will be building a simple API that manages the users for our demonstration application. To follow along you should have the pre-requisites:
- A good grasp of JavaScript fundamentals
- An AWS account and developer credentials
- Node and npm installed locally

The pricing model is also good for new or lightly used applications because you are charged by actual use rather than for reserved capacity. So let’s say your API services 1000 requests a month. You are only going to be charged for the computing time it took to run those requests…
