## What it is
Nerv is a virtual-dom based JavaScript/TypeScript UI library with an identical React 16 API, offering high performance, a tiny ~9KB gzipped bundle, and IE8 compatibility. It supports isomorphic rendering, Error Boundaries, Portals, and ships with Redux bindings, devtools, and server-rendering packages.

## Use cases
- build a React-style SPA that must support legacy browsers like IE8
- replace React with a smaller, faster drop-in alternative
- server-side render React-compatible components
- use Redux with a React-compatible library
- ship a tiny frontend bundle for performance-critical pages

## When to choose
- you need React's API but must support IE8 or very old browsers
- bundle size and rendering performance are critical
- you want a drop-in React 16-compatible renderer

## When to avoid
- you need a modern, actively maintained ecosystem - the project has had no releases since 2021
- you rely on the latest React features or the broader React ecosystem
- legacy browser support is not a requirement - use React or Preact instead
