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 🙏

EntityManager implements rational indexing & cross-shard querying at scale in your NoSQL database so you can focus on your application logic.

The Typescript refactor is still in flux, but stabilizing! Still fleshing out the demo & documentation.

If you have any questions, please start a discussion. Otherwise stay tuned!

Why?

Traditional relational database systems like MySQL or SQL Server implement indexing & scaling strategies at a platform level based on schemas defined at design time.

NoSQL platforms like DynamoDB offer far better performance at scale, but structured index & shard keys must be defined as data elements and exploited by application logic in data retrieval & cross-shard queries. They shift the burden of complexity from the database platform to the developer!

EntityManager encapsulates a provider-agnostic, highly opinionated approach to the single-table design pattern.

With EntityManager, you can:

  • Define related data entities & structured keys wth a simple, declarative configuration format.

  • Specify a partition sharding strategy that maximizes query performance while permitting planned, staged scaling over time.

  • Add or remove structured index keys from entity data objects with a single method call.

  • Perform paged, cross-shard, multi-index queries with a single method call.
