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.

convex-duckdb-sync

CLI client for syncing Convex data into a local DuckDB database through a Convex DuckDB proxy.

npx convex-duckdb-sync install
npx convex-duckdb-sync status
npx convex-duckdb-sync refresh
npx convex-duckdb-sync refresh --full

Config

The CLI reads only:

.convex-duckdb/config.json

Create it with:

npx convex-duckdb-sync install

Required keys:

| Key | Purpose | | --- | --- | | CONVEX_DUCKDB_PROXY_URL | Mirror proxy URL | | CONVEX_DUCKDB_ACCESS_TOKEN | Bearer token for mirror data routes |

The CLI does not load environment variables or .env files.

Sync behavior

Incremental sync fetches document deltas from /api/document_deltas.
Full restore downloads collection snapshots through /api/json_schemas and /api/list_snapshot, then builds .convex-duckdb/data.duckdb.
If the mirror retention window expired, refresh performs a full restore automatically.

Query with the DuckDB CLI:

duckdb -readonly .convex-duckdb/data.duckdb -markdown <<< "SELECT count(*) FROM table_name;"

See the root README for proxy setup and skills/convex-duckdb-sync for reusable agent query patterns.
