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 🙏

@umbra-privacy/nimbus-storage-solana

The Solana wallet's storage: an ordered key-value port with all-or-nothing conditional commits, the row envelope every store writes, the stores built on it, and the backends that implement the port.

Most apps don't install it directly. It is a storage engine of @umbra-privacy/nimbus-solana-web, which installs it for you.

Pre-release (0.x): every API, type and behaviour is subject to change at any time, as and when the Nimbus Privacy team (built by Umbra Privacy) decides or requires.

Install

pnpm add @umbra-privacy/nimbus-storage-solana

Entry points

  • @umbra-privacy/nimbus-storage-solana: The storage port, the row envelope and ordered key encoding.
  • @umbra-privacy/nimbus-storage-solana/note-store: The note store: the wallet's notes, their nullifiers, leases, attempts, balances and feed positions.
  • @umbra-privacy/nimbus-storage-solana/record-store: The record store: the wallet's records judged from the records feed, and its history.
  • @umbra-privacy/nimbus-storage-solana/commitment-tree-store: One pool's commitment tree, built locally from the feeds, for the wallet's own Merkle paths and roots.
  • @umbra-privacy/nimbus-storage-solana/nullifier-set-store: One turnstile's nullifiers as an indexed tree, to answer whether a nullifier is spent.
  • @umbra-privacy/nimbus-storage-solana/indexeddb: The IndexedDB backend, for browsers.
  • @umbra-privacy/nimbus-storage-solana/sqlite: The SQLite backend, over a synchronous driver the caller supplies.
  • @umbra-privacy/nimbus-storage-solana/memory: The in-memory backend, for tests and short-lived tools.
  • @umbra-privacy/nimbus-storage-solana/testing: The conformance suite every backend must pass, and the contract suites of the tree and nullifier stores.
