I published a helpful reference:
• Service worker-first architecture (not just PWA features)
• Offline data update batching w/IndexedDB staging
• Multi-user optimistic concurrency control with 3-way merge
• Docker Testcontainers w/cov
• Vanilla JS

Just replaced gulp in a legacy #NodeJS project with #NBS (node-build-stream). Fixed all CVEs, reduced legacy deps, works with #AI agents, no-load mental transition, and a little bit faster to boot. Easy, no-brainer win.
npm: node-build-stream

jam-build v2.13.0: Gulp is officially retired. The entire #webdev build pipeline now runs on *node-build-stream* — no deps, direct tools, a pure-stream fingerprinting revision stage, and logging.

node-build-stream is out: a zero-dep, Node 24+ streaming build runner that replaces Gulp's core (~20% faster) while staying compatible with existing Gulp plugins. File-stream oriented, not Vite-style module-graph: batch arbitrary files, automate any task.

Clients should know what an AI job costs and how long it takes before it runs. My method: rehearse on a local model, meter every token with a proxy, convert to a hosted-API cost range, time it, then check against a small paid pilot. Packaging it as a reusable kit next.

Messy data is the norm. My "location" column had blanks, "Earth", bare cities, 65 languages. My tool gives three answers: confident, unstated, unresolved. A wrong confident label costs more than an honest "I don't know." Zero wrong confident calls across thousands of tests.

Reminder: Claude Code can test if a skill or plugin actually improves Claude's answers.
> claude plugin eval init
Tell Claude what a good result looks like in your plugin's folder and it writes the test cases for you.
> run claude plugin eval .

🚀 agent-skills: Compiles a curated rule corpus into tiered agent skills for Copilot + AGENTS.md. Every rule has evidence anchors into your repo, so drift becomes a named rule ID, not silent rot. Pure Node, zero deps.

🚀 #localnerve jam-build v2.12.2 emits JSON-LD data islands per page, generated from the same source that renders the human markup — one dataset, two outputs: what people read and what AI agents parse.
Built for Agentic Browsing. No drift.

🚀 web-component-build v4.0.0
* Multi-template components go first-class — `templates` is the only API, outputs are a named map (result.html[name]), per-template CSS overrides
* Syntax-aware injection

Trusted Types Bootstrap v1.0.0 🚀
One import + one config call replaces the ~90-line inline bootstrap every app writes for require-trusted-types-for 'script'. Escaping createHTML, same-origin scripts, opt-in DOMPurify tier.

Hand-maintained Trusted Types drift as your app grows.
@localnerve/trusted-types-rules v1.0 audits every injection sink, finds createPolicy() registrations in minified bundles, and emits the trusted-types #CSP directive — catching escapes at build time.

🚀 @localnerve/web-component-build v3.5.0:
HTML/CSS injection into your JS string literals is now syntax-aware (acorn AST) — markup w/quotes, backticks & ${} won't break your code. Multi-template support w/ `templates`. Non-breaking.

jam-build v2.12.1 🎉
Playwright tests now run against the real production build — fingerprints, minified bundles, hash-CSP, Trusted Types, TLS. All three browsers, full coverage. We test what we ship.

Trusted Types shouldn't be hand-computed CSP policy lists.
A new package fixes that:

Open source foundations don’t run on “magic piles of money.”
Registries, CDNs, CI pipelines, security response and compliance work all require sustained support. Read why OpenJS joined peers in signing “Open Infrastructure is Not Free.”

The new if() selector in CSS lets you write conditional styles inline.
You can also switch based on custom properties:

LocalNerve published a rather detailed, full featured JAM stack reference project showing how to build a full featured webapp around a service worker with minimal code and technical debt.
