## What it is
Solid is a declarative JavaScript library for building user interfaces that compiles JSX templates to real DOM nodes instead of using a Virtual DOM. It provides fine-grained reactivity, so when state changes, only the code that depends on it reruns, delivering high performance.

## Use cases
- build a fast reactive single-page app without a virtual dom
- create ui components with fine-grained state updates
- build a declarative frontend with jsx and signals
- migrate from react to a more performant ui library
- build a reactive counter or interactive widget
- develop a high-performance web app with minimal re-renders

## When to choose
- you want react-like jsx ergonomics with better runtime performance
- fine-grained reactivity and no virtual dom overhead matters
- you prefer components that run once with signals for state

## When to avoid
- your team depends on the react ecosystem of libraries and tooling
- you need a framework with a huge job market and community size
- you want server-first rendering with mature full-stack conventions out of the box

## Facets
- artifact type: library
- maturity: active
- function: frontend-framework, state-management, ui-components, templating
- domain: web-development, frontend
- platform: browser, cross-platform
