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 🙏

@effectstream/bitcoin-core

A pinned Bitcoin Core binary, packaged for npm. Installing this drops a versioned bitcoind and bitcoin-cli into node_modules/.bin so the EffectStream orchestrator and E2E tests can boot a local regtest without each developer running their own install script.

  • Pins Bitcoin Core 28.1 for local regtest.
  • Linux / macOS, x64 and arm64.
  • Pairs with @effectstream/bitcoin-contracts for generate-blocks and wait-for-block.
  • Used by the orchestrator's Bitcoin step.

Install

bun add @effectstream/bitcoin-core
# or
npm install @effectstream/bitcoin-core

Currently pins Bitcoin Core 28.1.

Standalone usage

Once installed, the binary is on your local PATH (via node_modules/.bin).

# Start a regtest daemon
bunx bitcoin-core -regtest -daemon

# Or invoke through this package directly
bun run --bun @effectstream/bitcoin-core/start -- -regtest -daemon

The package downloads the pinned tarball for your OS/arch on first run:

| Platform | Architecture | |---|---| | linux | x64, arm64 | | darwin | x64, arm64 |

Pair with @effectstream/bitcoin-contracts for the generate-blocks and wait-for-block helpers.

Inside EffectStream

The orchestrator (@effectstream/orchestrator) declares this as a dependency of its bitcoin-core step, so bun packages/build-tools/orchestrator/src/cli.ts start brings up a regtest chain automatically. The Bitcoin E2E suite at e2e/bitcoin/ runs against this same binary.
