NFSFU234 Open Source Day: Three Tools, One Scope

Nyuiring-yoh R. Shifu-Nfor — Tue, 25 Aug 2026 17:13:36 +0000

Today's NFSFU234 Open Source Day — the first one we've run. FormValidation and TourGuide, previously two separate unscoped npm packages built years apart, are moving under the @nfsfu234 scope. ShotSweep, a new CLI for visual regression testing, launches scoped from day one. For the first time, all three live under one namespace.

Here's what's actually in each release.

ShotSweep — new, v1.0.0

A CLI that captures screenshots of a site and diffs them between runs. A build can pass, every test can pass, a page can return 200 — and still look broken visually. This closes that gap.

npm install -g @nfsfu234/shotsweep

shotsweep capture --sitemap https://example.com/sitemap.xml --viewport 1440x900 --dark
shotsweep diff before/manifest.json after/manifest.json

Full sitemap capture, including sitemap indexes
Full-page or sectioned screenshots, multiple viewports, light/dark emulation per run
Auth support: form login with saved sessions, bearer tokens, custom headers, cookies
--replace-origin to point a production sitemap at localhost/staging without maintaining a second URL list
Deterministic pixel diffing (shotsweep diff) with configurable thresholds, non-zero exit on a real regression — built to gate CI
--resume, --concurrency, --retries for large sites; --describe for an AI-ready run summary (the diff decision itself stays fully deterministic)

We ran it against our own docs site before shipping: 28 routes, light and dark mode, 136 manifest entries per run, 0 capture errors on either run.

TourGuide v2

npm install @nfsfu234/tour-guide

defineConfig() + <TourProvider> for shared config across multiple tours instead of repeating props per instance
Real accessibility pass: focus trapping, keyboard nav, ARIA roles, screen-reader announcements
First real automated test suite (Vitest)
Tooltip positioning fixes near viewport edges; highlight cleanup now correctly restores a target element's original inline styles after a tour ends

⚠️ Breaking: package renamed from nfsfu234-tour-guide to @nfsfu234/tour-guide.

FormValidation v3

npm install @nfsfu234/form-validation

The largest release in this library's history:

.submit(), .validate(), and .validateInput() are now consistently async
File/image upload validation (type, size, dimensions)
configureForms() / autoInit() for site-wide validation rules across multiple forms from one config
Real Jest test suite, CI-gated releases

The change worth calling out on its own: we removed client-side password hashing (.hashPassword(), .verifyPassword(), .passwordMatch(), and the bcryptjs dependency) entirely. It never protected a password in transit — that's what TLS and your backend are for — so it was providing the appearance of security without the substance. Not a bugfix. A feature we decided shouldn't have existed.

Why one scope matters more than any single feature here

These three tools were built at different points over several years as separate, unrelated packages. Getting them under one @nfsfu234 namespace isn't a technical achievement so much as a bookkeeping one — but it's the thing that turns "three tools I happened to build" into "an ecosystem," and that distinction is doing real work for how we plan what comes next.

All three are MIT licensed and open for issues/PRs starting today. If you try one and something's broken, that's useful — open an issue.
