## What it is
LiveSvelte is an Elixir library that integrates Svelte components into Phoenix LiveView, providing seamless end-to-end reactivity over websockets. It supports server-side rendering of Svelte, a sigil-based DSL, TypeScript, Tailwind, and slot interoperability.

## Use cases
- build real-time chat UIs in Phoenix with Svelte components
- add client-side interactivity to a LiveView app without a separate SPA
- server-side render Svelte components inside an Elixir web app
- sync complex local frontend state with a Phoenix server over websockets
- use Svelte animations and scoped CSS in a LiveView project
- create hybrid apps where LiveView handles forms and Svelte handles rich UI

## When to choose
- you use Phoenix LiveView and want Svelte's DX, animations, and scoped CSS
- you need complex client-side state alongside server-driven real-time updates
- you want SSR for Svelte within an Elixir stack

## When to avoid
- your project is not built on Phoenix or Elixir
- you need a fully client-side SPA without a server-rendered backend
- your production environment cannot run Node.js 19+ for SSR
