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.

@sisu-ai/mw-context-compressor

Middleware that compresses long conversation context using the model itself.

Wraps ctx.model.generate to summarize older messages when the context grows beyond a size threshold.
Preserves the last keepRecent messages unmodified.
Keeps essential facts and URLs; emits a compact assistant summary message that replaces older history.

Usage

import { contextCompressor } from '@sisu-ai/mw-context-compressor';

agent.use(contextCompressor({ maxChars: 200_000, keepRecent: 8, summaryMaxChars: 12_000 }));

Options

maxChars (default 200k): approximate character budget before compressing.
keepRecent (default 8): number of most recent messages to retain verbatim.
summaryMaxChars (default 12k): target maximum size of the generated summary message.

Note: This is a best-effort char-based heuristic; exact token accounting varies by model.
