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 🙏

@iov/bns

npm version

This package is an implementation of the BlockchainConnection interface for the BNS blockchain (currently just as bcp-demo prototype). It should be able to adapt this code fairly easily to support any other weave based blockchain as well.

This provides a reference implementation of the full feature set of BlockchainConnection, so it is also a good read when starting support of another blockchain.

Simplest usage, to use auto-detecting tendermint client and standard bns transaction parser:

const connection = await BnsConnection.establish(
  "wss://rpc-private-a-x-exchangenet.iov.one",
);

API Documentation

https://iov-one.github.io/iov-core-docs/latest/iov-bns/

The main entry point is the BnsConnection, which creates a Tendermint client (from iov-tendermint-rpc) and a codec to parse transactions. The BNS codec for reading and writing transactions (also useful for MultiChainSigner) is exported as top-level bnsCodec.
