About

High-Velocity Content Engine (HVCE) is a Node.js framework that turns JSONL catalogs into crawlable directory sites—faceted listings, entity profiles, sitemaps, and AI-readable twins—sold under annual license tiers.

What this site is

This domain (hypersonicseo.com) is the public demo for High-Velocity Content Engine (HVCE), a software framework that builds multi-dataset directory and catalog websites from flat JSONL data files.

It shows how HVCE renders in production: sample catalogs, sales documentation as entity profiles, and licensing information for operators who want to run the same stack on their own domains.

What HVCE does

HVCE reads structured datasets from data/*.jsonl and produces:

  • A landing hub and per-dataset catalog indexes with faceted browse
  • Individual entity profile pages
  • Optional map and proximity tooling when a dataset enables it
  • Side-by-side compare (/compare/)
  • Embed / widget feeds
  • Automatic sitemap.xml, robots.txt, llms.txt, semantic-manifest.jsonl, and markdown twins (?format=md or index.md on static export)
  • JSON-LD structured data aligned with the same source values as the HTML and markdown outputs

There is no separate database or Redis layer for the public catalog: JSONL is the source of truth. Catalogs load into memory at boot (or at build time for static export).

Delivery modes

The same templates and SEO surfaces support two modes:

  1. Live SSR — Node.js + Express serves fully formed HTML; facet URLs stay crawlable on the server.
  2. Static export — npm run build writes a dist/ tree of HTML, assets, and discovery files for CDN or nginx hosting with no Node process at request time.

Operators manage content and site chrome through the Control Deck at /control (datasets, home directory, main nav, site pages, license panel).

Who it is for

HVCE is aimed at operators who need directory or catalog sites driven by structured rows—product matrices, geo directories, research or heritage collections, affiliate hubs, and similar inventories—without maintaining a separate SPA frontend for public pages.
