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 🙏

Readme

MergeBrake

MergeBrake catches database-breaking pull requests before merge. It maps schema changes to the application code they will break, detects AI-generated PR signals, and gives reviewers a safe rollout plan instead of a generic warning.

npx mergebrake scan "prisma/migrations/**/migration.sql" \
  --commits ./.git/COMMIT_EDITMSG

For PR-style checks, scan only migration files changed since the base branch:

npx mergebrake scan "prisma/migrations/**/migration.sql" \
  --changed-since origin/main

For deploy-order checks, compare the PR checkout with a base-branch checkout:

npx mergebrake scan "prisma/migrations/**/migration.sql" \
  --base-repo ../my-app-base

Output formats:

  • terminal for local development
  • markdown for PR comments
  • github for GitHub Actions annotations
  • json for custom tooling
