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.

pi-show-diff

Pi extension for local development: open a visual Diff2Html view of what your current branch would contribute to main.

It is not a sharing service. It does not upload diffs. It writes a temporary local HTML file and opens it in your browser.

Repository: https://gitlab.com/mjfuertesf/pi-show-diff

Screenshots

Line-by-line:

Side-by-side:

Install

pi install git:gitlab.com/mjfuertesf/pi-show-diff
pi install npm:@mjfuertesf/pi-show-diff

Usage

/show-diff

Without arguments, diffs against the remote tracking branch: origin/main, then origin/master. Falls back to the local branch only if no remote ref is found.

Pass an explicit ref to use it literally:

/show-diff develop          # local branch "develop"
/show-diff origin/develop   # remote tracking branch
/show-diff abc123           # specific commit

What it does

Runs a PR-style diff: git diff <base>...HEAD
Renders it with Diff2Html
Opens a local browser preview
Warns if the working tree is dirty
Includes committed branch changes only

Pi tool

Also registers:

show_review_diff({ base?: string })

Useful when a Pi skill or agent should open the same local review preview.

Development

npm test
npm pack --dry-run
