Deploying Express App to AWS Lambda

Question

I've built a REST API using Express and Node.js. I've broken it up into the three-tier architecture and I'm looking to deploy it to AWS Lambda, but am completely overwhelmed about where to start; articles I've read and videos I've watched don't account for completed REST APIs. I know my code needs a handler function, and that's about it.

Accepted Answer

To deploy your Express-based REST API to AWS Lambda, first, create a Lambda handler function that adapts your Express app to work with Lambda. Then, package your app and its dependencies into a deployment package. Finally, deploy the package to Lambda and configure API Gateway to trigger your Lambda function to handle HTTP requests. You can follow the documentation [Building Lambda functions with Node.js](https://docs.aws.amazon.com/lambda/latest/dg/lambda-nodejs.html)
