Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.


Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

DR Opinionated Constructs to get resources





This package contains DR specific implementations of most of the types above. This will take some opinions from Accelerate, for example, using the SSM Parameter Store to retrieve ARN values for IAM roles.


| Name | Description | --- | --- | Encryption | Reads an Encryption Key from SSM /dr/global/encryption/{keyName} where Keyname is a property passed | IAM | Reads 7 different IAM roles from SSM all in /dr/global/iam. CodeBuild (NonProd and Prod), CodePipeline (NonProd and Prod), CloudFormation (NonProd and Prod) along with Lambda Execution Role (read during build from the appropriate account) | SsmProperties | Class to read SSM properties. | VpcConfig | Given a VpcId, SecurityGroup Ids and Subnet Ids it will read these resources from the account/region given to the stack. VPC requires concrete values to be read (cannot come from SSM or other dynamic sources) | VpcEndpoint | Given a VpcConfig, it can read an existing VPC Endpoint or create a new one.


The following factories exist to build their corresponding construct above. This allows these factories to be passed to the main stack allowing you to customize construction of the objects or supply your own object with your implementation.

  • EncryptionFactory
  • EncryptionFactoryProps (takes properties to specify region or a different key)
  • IamFactory
  • SsmPropertiesFactory
  • VpcConfigFactory


import { VpcConfigFactory } from '@makemydeal/cdk-dr-constructs';

const factory = VpcConfigFactory({
    // VPC Configuration coming from the process.env variables from CodeBuild.  These NEED to be concrete, cannot come from SSM directly in the stack

Parameter Store Dependencies

All Deployments

| Key | Construct | Description | --- | --- | --- | /dr/global/iam/code-build-service-role | IAM | Code Build Service Role | /dr/global/iam/crossaccount-build-role | IAM | Role used for cross account builds (production) | /dr/global/iam/code-pipeline-service-role | IAM | Code Pipeline Service Role | /dr/global/iam/crossaccount-deploy-role | IAM | Role used for cross account deployment (production) | /dr/global/iam/cfn-service-role-prod | IAM | Production Account CloudFormation role | /dr/global/iam/cfn-service-role | IAM | Non-Production Account CloudFormation role | /dr/global/iam/lambda-execution-role | IAM | Lambda Execution Role | /dr/global/iam/s3-replication-role | IAM | Role used to set up replication between s3 buckets | /dr/global/certificates/makemydealcom | DRCertificate | Default ARN to use for Certificate | /dr/global/network/hosted-zone-ids/makemydealcom | DRHostedZone | Default Hosted Zone ID

Single Region Deployments

To support backward compatibility, we will support the existing keys when a region is not specified.

| Key | Construct | Description | --- | --- | --- | /dr/global/encryption/basicKey | Encryption | KMS key used for encryption

Multi Region Deployments

For multi region deployments, we need to support a region for these values. This is used in the pipeline only so the keys change

| Key | Construct | Description | --- | --- | --- | /dr/global/cdk/regions/${region}/encryption/basicKey | Encryption | KMS key used for encryption
