TypeScript Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create VPC
const vpc = new aws.ec2.Vpc("main", {
    cidrBlock: "10.0.0.0/16",
    enableDnsHostnames: true,
    tags: {
        Name: "main-vpc",
    },
});

// Create subnet
const subnet = new aws.ec2.Subnet("public", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-east-1a",
});

// Export outputs
export const vpcId = vpc.id;
export const subnetId = subnet.id;

Common Commands

# Create new project
pulumi new aws-typescript

# Preview changes
pulumi preview

# Apply changes
pulumi up

# Destroy resources
pulumi destroy

# View stack outputs
pulumi stack output

Configuration

# Set config
pulumi config set aws:region us-east-1

# Set secret
pulumi config set --secret dbPassword mySecret123

# Get config
pulumi config get aws:region

Best Practices

Use Stack References

const infraStack = new pulumi.StackReference("org/infra/prod");
const vpcId = infraStack.getOutput("vpcId");

Component Resources

class MyApp extends pulumi.ComponentResource {
    constructor(name: string, args: MyAppArgs, opts?: pulumi.ComponentResourceOptions) {
        super("custom:app:MyApp", name, {}, opts);
        
        // Create resources
    }
}
