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 🙏

Lambda Error SNS Sender

A simple solution to improve the CloudWatch alarm to receive Lambda error details by email. Available as CDK construct or as CloudFormation.

How does it work?

  1. Lambda is subscribed to the SNS topic where you receive your alarms. There is a message body subscription filter that limits errors based on the Lambda error metric. You must change the filter if you defied your metric in some other way, not the default one.
  2. Lambda analyzes the message, finds a log of the failed Lambda, and queries the log group for the period that the metric was configured, plus some additional safety time, so we do not miss that error message. It extracts just a number of errors that can fit in one SNS message.
  3. Lambda sends errors to the same SNS that you use for alerts. So, apart from the Alarm message for changing the error state, you will receive an additional one with detailed error messages.

The solution is in two forms:

  • CDK construct If you are building your system with CDK (or SST). Available for TypeScript, Java, C#, Python, and Go.
  • CloudFormation For existing solutions, so you do not have to modify them. You deploy and point to the existing SNS used for CloudWatch alarms.

If you are interested how to use it and how was build see the blog post.
