Lambda-backed REST API

A simple API demonstrating an integration between AWS API Gateway (REST) and AWS Lambda.

Deploying and running the program

This example provides API endpoints which are executed by lambda using TypeScript and AWS.

This sample uses the following AWS products:

Prerequisites

  1. Install Pulumi

  2. Create a new stack:

    $ pulumi stack init aws-ts-apigateway-lambda-serverless

  3. Set the AWS region:

    $ pulumi config set aws:region us-east-2

  4. Install NPM modules via npm install or yarn install.

Deploy the App

  1. Run pulumi up to preview and deploy changes:

Outputs:
    endpointUrl: "https://***.execute-api.us-east-2.amazonaws.com/stage/"

Resources:

Duration: 36s`
  1. To view the runtime logs of the Lambda function, use the pulumi logs command. To get a log stream, use pulumi logs --follow.

Clean Up

  1. Run pulumi destroy to tear down all resources.

  2. To delete the stack itself, run pulumi stack rm. Note that this command deletes all deployment history from the Pulumi Console.

Summary

In this tutorial, you built a lambda-backed API on AWS using API Gateway, lambda functions, and Pulumi. This serverless solution is highly scaleable, resilient, and stateless.
