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.

About

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 🙏

Export Cognito app client credentials to SSM Parameter store

Background

Amazon Cognito is a powerful service for application authentication, authorization, and user management . When working with µservice applications, we can use AWS Cognito user pool authentication to implement a fine-grained service-to-service access control where each service has a dedicated resource server with pre-defined scopes for its resources(API Gateway, Lambda etc), and a dedicated app client with limited scopes it needs to access external resources. This service-to-service interaction normally starts with a user pool sign-in with the app client credentials where a JWT token will be returned from Cognito to the initiator for external resource access. We used to copy the app client credentials from AWS console and put to the configuration for each µservice manually. With the increasing number of µservices, we need a tool to do this securely and automatically for us.

How it works

A serverless hook will be triggered after the deployment to pull the app client credentials includes url, clientId, and clientSecret which will be merged as part of the application configuration(auth.cognito) stored in the configured SSM parameter. Note: Only when there are changes for any of these three fields will this plugin update the SSM parameter.

Installation

npm install serverless-app-client-credentials-to-ssm --save-dev

Configuration

plugin registration

Inside your project's serverless.yml file add following entry to the plugins section:

plugins:
  - serverless-app-client-credentials-to-ssm

plugin configuration

Then you need to add the plugin configuration to the custom section:

custom:
  serverless-app-client-credentials-to-ssm:
    userPoolId: ${ssm:/layered-apis/userPoolId}
    appClientName: ${self:custom.appClientName}
    parameterName: /layered-apis/${self:service}/${self:provider.stage}

Sample parameter

{
  "auth": {
	"cognito": {
	  "url": "https://asdfafdsa-systems-idp-nonprod.auth.ap-southeast-2.amazoncognito.com/oauth2/token",
	  "clientId": "h3p4a1sr9pu",
	  "clientSecret": "s1oglveco0hsfraoag90ebr107rmvo9g7u36h"
	}
  },
  "database": {
	"url": "https://asdfafdsa–instance1.123456789012.us-east-1.rds.amazonaws.com",
	"username": "9g7u36h",
	"password": "eco0hsfraoag90ebr107rmvo"
  }
}
