## What it is
Hypernova is a Node.js service from Airbnb that renders JavaScript views (e.g., React components) on the server via HTTP, returning HTML strings that clients can hydrate in the browser. It lets teams write view code once while keeping server-side rendering benefits like faster content delivery and SEO.

## Use cases
- server-side render React components from a Ruby or Node backend
- improve SEO by rendering JavaScript views as HTML on the server
- avoid duplicating markup in server templates and client JavaScript
- progressively enhance server-rendered pages with client-side JavaScript
- batch-render multiple views in a single HTTP request

## When to choose
- you maintain an existing Hypernova integration and need reference material
- you want a forkable base for a custom SSR microservice
- your stack renders JS views from a non-JavaScript backend like Ruby

## When to avoid
- you are starting a new project - the repository is archived with no updates or support
- your framework has built-in SSR (Next.js, Nuxt, Remix)
- you need actively maintained tooling or community support
