AWS CDK Constructs

Pipedream AWS CDK Constructs

A collection of CDK constructs used in various blog posts and other public-facing examples.

Usage

See the AWS CDK TypeScript guide for general information on the AWS CDK.

import { Stack, StackProps } from "aws-cdk-lib";
import { Construct } from "constructs" 
import { DDBDeletedItemsToHTTPS } from "@pipedream/cdk-constructs"

export class DDBDeadMansSwitch extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    new DDBDeletedItemsToHTTPS(this, 'DDBDeletedItemsToHTTPS', {
      notificationURL: "https://pipedream.com",
    });
  }
}

Growthbook

Growthbook provides an open-source, Bayesian experimentation platform. We use Growthbook at Pipedream and have released the ECS deployment we use as a CDK construct:

import { Stack, StackProps } from "aws-cdk-lib";
import { Construct } from "constructs" 
import { Growthbook } from "@pipedream/cdk-constructs"

export class GrowthbookStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    new Growthbook(this, 'Growthbook', {
      hostedZoneName: "yourdomain.com",
      growthbookHost: "growthbook",
      emailHost: "smtp.sendgrid.com",
      emailPort: "587",
      emailFromAddress: "noreply@yourdomain.com" 
    });
  }
}

This stack assumes you have your own hosted zone in Route53 where DNS records can be created, and a MongoDB cluster accessible from the Growthbook ECS instance. See the Growthbook docs for more information.

The stack also pulls secrets from AWS Secrets Manager, and assumes the following secrets have been created prior to creating the stack:

prod/mongo/secretMongoURI
prod/mongo/secretJwtSecret
prod/mongo/secretEncryptionKey
prod/email/secretUsername
prod/email/secretPassword

Useful commands

• npm run build - Compile Typescript to JS
• npm test - Run CDK infra tests
