## What it is
Surface is a server-side rendering component library for the Phoenix web framework, built on top of Phoenix LiveView. It offers an HTML-centric templating language with components as modules, declarative properties, slots, contexts, and compile-time checking, enabling rich interactive UIs with minimal custom JavaScript.

## Use cases
- build server-rendered interactive UIs in a Phoenix LiveView app
- write Phoenix templates with an HTML-centric component syntax
- create reusable Elixir components with props, slots, and contexts
- get compile-time checking of template structure and component properties
- reduce the amount of custom JavaScript in a Phoenix web app
- add a component library to an existing Phoenix project

## When to choose
- you are building a Phoenix LiveView application and want a more ergonomic, HTML-centric component API
- you want compile-time validation of templates, props, slots, and events
- you prefer server-side rendering with minimal custom JavaScript
- you want components that can be stateless, stateful, renderless, or compile-time

## When to avoid
- your project is not built on Elixir/Phoenix
- you need a heavy client-side SPA with complex in-browser state
- you are happy with plain HEEx/LiveView templates and don't want an extra templating layer
- you need a framework that runs rendering in the browser rather than on the server
