What is AWS Cloud Development Kit (CDK)

 // 1️⃣ Resources are imported from 'aws-cdk-lib'
import { App, Stack, StackProps } from 'aws-cdk-lib';
import * as s3 from 'aws-cdk-lib/aws-s3';

// 2️⃣ Definition of the stack to be provisioned
export class MyStack extends Stack {
  constructor(scope: App, id: string, props?: StackProps) {
    super(scope, id, props);

    // 3️⃣ Creates a bucket, using this L3 construct for S3 resources
    const myBucket = new s3.Bucket(this, 'my-bucket');
  }
}

// 4️⃣ App instantiation
const app = new App();

// 5️⃣ Stack instantiation
new MyStack(app, `cdk-stack-dev`, {
  stackName: `cdk-stack-dev`,
  env: {region: process.env.CDK_DEFAULT_REGION},
});

import * as s3 from 'aws-cdk-lib/aws-s3';

const myBucket = new s3.Bucket(this, 'my-bucket', {
  blockPublicAccess: BlockPublicAccess.BLOCK_ALL,
  bucketName: ``, // ⚠️ Here is defined the s3 bucket name
  encryption: BucketEncryption.S3_MANAGED,
  enforceSSL: true,
  eventBridgeEnabled: true,
  removalPolicy: RemovalPolicy.RETAIN,
  versioned: true,
});
