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.

flowstate finance accounting ynab double-entry

@epicdm/flowstate-finance-core

Pure-functional library bridging YNAB primitives (synced via flowstate-connector) to the double-entry accounting model used by flowstate-app-finance.

What this package owns

Canonical journal-entry types (JournalEntryDraft, JournalLineDraft, JournalEntrySource)
Balance utilities (isJournalEntryBalanced, calculateAccountBalance, calculateTrialBalance)

Future phases (per docs/specs/2026-05-02-flowstate-finance-core-posting-engine-design.md) will add:

posting/ — pure projection from YNAB primitives to JournalEntryDraft
mapping/ — source-account → COA resolver + Suspense fallback
schemas/ — VCA Zod schemas for source_account_mappings and org_settings
post-batch.ts — orchestrator (postYnabTransactions)

Why

The flowstate-app-finance reports (P&L, Balance Sheet, Trial Balance, GL) consume journalentries + journallines. YNAB syncs into raw records. This package is the bridge — and the canonical owner of the types both layers share.

Status

Phase 1: Package scaffold + lifted types (this commit)
Phases 2-10: see the design spec

Install

This is an internal monorepo package. Consumers reference it via workspace protocol:

{
  "dependencies": {
    "@epicdm/flowstate-finance-core": "workspace:*",
  },
