How to use Claudia.js to Deploy a Serverless API to AWS

In this tutorial, we’ll demonstrate how to use Claudia.js to deploy a Serverless API to AWS. Learn how to build and deploy an Express.js application to AWS Lambda.

Learn how to use Claudia.js to deploy a serverless API to AWS and build and deploy an Express.js application to AWS Lambda.

AWS Lambda is a serverless technology that lets you run code without provisioning or managing servers. It supports most popular programming languages, including Node.js.

Why go serverless? The benefits of deploying a serverless API include auto-scalling, zero server administration, the ability to pay only for what you use, increased velocity, etc. Running your Express.js API on AWS Lambda is a great way to take advantage of all these benefits.

However, Lambda doesn’t have direct support for frameworks such as Express.js built with programming languages such as Node.js. That’s where an adapter such as Claudia.js comes in.

Claudia.js sits between AWS Lambda and your Express.js app and converts Lambda invocation events from various AWS sources, such as API gateways or application load balancers, into HTTP events that your Express app can listen to.

In this tutorial, we’ll demonstrate how to use Claudia.js to deploy a serverless API to AWS. We’ll show you how to build and deploy an Express.js application to AWS Lambda.

Here’s what we’ll cover:

  • What is Claudia.js?
  • Getting started with Claudia.js
  • Generating an Express.js app
  • Configuring your Express.js app
  • Deploying to AWS Lambda

The tutorial assumes that you’re conversant with Node.js, Express.js, and Lambda. Lambda expects your code to be structured a certain way. So if you want to use it to host something like an Express app, you’ll need to use an adapter like Claudia.js.


What is Claudia.js?

Claudia.js is a tool designed to simplify deployment of Node.js projects to AWS Lambda and API Gateway. It automates deployment tasks so you don’t need to worry about introducing errors and configures everything the way you would expect it to be set up out of the box.

According to the official website, Claudia’s primary objective is to help JavaScript developers get started using Lambda microservices easily so they can “focus on solving important business problems instead of dealing with AWS deployment workflows.”
