AWS Serverless Infrastructure with Pulumi and Typescript— Tutorial

This guide will walk you through creating a simple serverless AWS infrastructure using Pulumi with TypeScript. By the end of this tutorial, you’ll have a working API connected to Lambda functions with DynamoDB storage and an S3 bucket.

Architecture Overview

Here’s how our AWS services connect and communicate:

Prerequisites

Before starting, ensure you have:

1. Node.js and npm installed
2. AWS CLI installed and configured with proper credentials
3. Pulumi CLI installed

Step 1: Create a new Pulumi project

# Create a directory for your project
mkdir pulumi-aws-serverless
cd pulumi-aws-serverless

# Initialize a new Pulumi TypeScript project
pulumi new aws-typescript

During initialization, you’ll be asked to provide:

• Project name (e.g., pulumi-aws-serverless)
• Project description
• Stack name (e.g., dev)
