# Pulumi Components

Build reusable infrastructure components with Pulumi to create modular, composable, and maintainable infrastructure.

## Overview

Pulumi ComponentResources allow you to create higher-level abstractions that encapsulate multiple cloud resources into logical units. This enables code reuse, better organization, and more maintainable infrastructure code.

## Basic ComponentResource

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

export interface WebServerArgs {
    instanceType?: pulumi.Input<string>;
    ami?: pulumi.Input<string>;
    subnetId: pulumi.Input<string>;
    vpcId: pulumi.Input<string>;
}

export class WebServer extends pulumi.ComponentResource {
    public readonly instance: aws.ec2.Instance;
    public readonly securityGroup: aws.ec2.SecurityGroup;
    public readonly publicIp: pulumi.Output<string>;

    constructor(name: string, args: WebServerArgs, opts?: pulumi.ComponentResourceOptions) {
        super("custom:infrastructure:WebServer", name, {}, opts);

        const defaultOpts = { parent: this };

        // Create security group
        this.securityGroup = new aws.ec2.SecurityGroup(`${name}-sg`, {
            vpcId: args.vpcId,
            description: "Security group for web server",
            ingress: [
                {
                    protocol: "tcp",
                    fromPort: 80,
                    toPort: 80,
                    cidrBlocks: ["0.0.0.0/0"],
                },
                {
                    protocol: "tcp",
                    fromPort: 443,
                    toPort: 443,
                    cidrBlocks: ["0.0.0.0/0"],
                },
            ],
            egress: [{
                protocol: "-1",
                fromPort: 0,
                toPort: 0,
                cidrBlocks: ["0.0.0.0/0"],
            }],
            tags: {
                Name: `${name}-sg`,
            },
        }, defaultOpts);

        // Create EC2 inst
