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:
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.
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.
Serverless Express enables you to easily host Express.js APIs on AWS Lambda and AWS HTTP API. Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more!
AWS KMS is a Key Management Service that let you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.
Serverless Proxy with AWS API Gateway and AWS Lambda. We can communicate between Public and Private instance via a Serverless Proxy thanks to AWS Api Gateway and AWS Lambda. Github Webhook calls a Public API Gateway, API Gateway triggers a Lambda attached to VPC.
