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

Haybarn extension: ossie

The Apache Ossie (incubating) reference implementation for DuckDB. Reads Ossie semantic model files in YAML or JSON and answers semantic queries against the tables in DuckDB, from a single binary, with no infrastructure. Also exposes the semantic layer via MCP.

Source: https://github.com/iqea-ai/duckdb-ossie
Catalog: Haybarn community extensions

Install

npm install @haybarn/ext-ossie-h1-5-5
# or use the exact version:
npm install @haybarn/[email protected]

npm picks the matching platform binary from the leaves below via its os / cpu / libc fields. No postinstall scripts, no network calls after npm install.

Available platforms (this version)

Installed automatically by npm install @haybarn/ext-ossie-h1-5-5 (npm picks the one matching your os/cpu/libc):

  • @haybarn/ext-ossie-h1-5-5-linux-arm64
  • @haybarn/ext-ossie-h1-5-5-win32-x64
  • @haybarn/ext-ossie-h1-5-5-darwin-arm64
  • @haybarn/ext-ossie-h1-5-5-linux-x64
  • @haybarn/ext-ossie-h1-5-5-darwin-x64

WebAssembly (duckdb-wasm)

Also built for duckdb-wasm. These are not installed by the meta above (npm has no wasm os/cpu to match) — install the variant matching your duckdb-wasm bundle (mvp / eh / threads) and point duckdb-wasm at the bundled asset:

  • @haybarn/ext-ossie-h1-5-5-wasm-threads
  • @haybarn/ext-ossie-h1-5-5-wasm-mvp
  • @haybarn/ext-ossie-h1-5-5-wasm-eh
npm install @haybarn/ext-ossie-h1-5-5-wasm-threads
import extUrl from '@haybarn/ext-ossie-h1-5-5-wasm-threads/bin/ossie.duckdb_extension.wasm?url';
await conn.query(`INSTALL ossie FROM '${extUrl}'`);
await conn.query(`LOAD ossie`);

Use it

Once installed, the .duckdb_extension binary lands in your project's node_modules/ tree under the matching leaf. The Haybarn engine auto-discovers it at startup; from a Haybarn SQL session:

LOAD ossie;
