-# Servable: a simple web framework
-
-[![CI](https://github.com/rm-dr/servable/workflows/CI/badge.svg)](https://github.com/rm-dr/servable/actions) 
-[![Cargo](https://img.shields.io/crates/v/servable.svg)](https://crates.io/crates/servable) 
-[![API reference](https://docs.rs/servable/badge.svg)](https://docs.rs/servable/)
-
-A tiny, convenient web micro-framework built around [htmx](https://htmx.org), [Axum](https://github.com/tokio-rs/axum), and [Maud](https://maud.lambda.xyz).
-Inspired by the "MASH" stack described [here](https://yree.io/mash) and [here](https://emschwartz.me/building-a-fast-website-with-the-mash-stack-in-rust).
-
-
-
-## Features
-
-`servable` provides abstractions that implement common utilities needed by an http server. \
-
-- response headers and cache-busting utilities
-- client device detection (mobile / desktop)
-- server-side image optimization (see the `image` feature below)
-- ergonomic [htmx](https://htmx.org) integration (see `htmx-*` features below)
-
-
--------------------
-
-
-## Quick Start
-
-```rust,ignore
-use servable::{ServableRouter, servable::StaticAsset, mime::MimeType};
-
-#[tokio::main]
-async fn main() {
-	let route = ServableRouter::new()
-		.add_page(
-			"/hello",
-			StaticAsset {
-				bytes: b"Hello, World!",
-				mime: MimeType::Text,
-			},
-		);
-
-	// usual axum startup routine
-	let app = route.into_router();
-	let listener = tokio::net::TcpListener::bind("0.0.0.0:3000")
-		.await
-		.unwrap();
-
-	axum::serve(listener, app).await.unwrap();
-}
-```
-
-# Core Concepts
-
-## The `Servable` trait
-
-The `Servable` trait is the foundation of this stack. \
-`servable` provides implementations for a few common servables:
-
-
-- `StaticAsset`, for static files like CSS, JavaScript, images, or plain bytes:
-	```rust
-	use servable::{StaticAsset, mime::MimeType};
-
-	let asset = StaticAsset {
-		bytes: b"body { color: red; }",
-		mime: MimeType::Css,
-	};
-	```
-
-- `Redirect`, for simple http redirects:
-	```rust
-	use servable::Redirect;
-
-	let redirect = Redirect::new("/new-location").unwrap();
-	```
-
-- `HtmlPage`, for dynamically-rendered HTML pages
-	```rust
-	use servable::{HtmlPage, PageMetadata};
-	use maud::html;
-	use std::pin::Pin;
-
-	let page = HtmlPage::default()
-		.with_meta(PageMetadata {
-			title: "My Page".into(),
-			description: Some("A great page".into()),
-			..Default::default()
-		})
-		.with_render(|_page, ctx| {
-			Box::pin(async move {
-				html! {
-					h1 { "Welcome!" }
-					p { "Route: " (ctx.route) }
-				}
-			})
-		});
-	```
-	`HtmlPage` automatically generates a `<head>` and wraps its rendered html in `<html><body>`.
-
-
-
-## `ServableRouter`
-
-A `ServableRouter` exposes a collection of `Servable`s under different routes. It implements `tower`'s `Service` trait, and can be easily be converted into an Axum `Router`. Construct one as follows:
-
-```rust
-# use servable::{ServableRouter, StaticAsset, mime::MimeType};
-# let home_page = StaticAsset { bytes: b"home", mime: MimeType::Html };
-# let about_page = StaticAsset { bytes: b"about", mime: MimeType::Html };
-# let stylesheet = StaticAsset { bytes: b"css", mime: MimeType::Css };
-# let custom_404_page = StaticAsset { bytes: b"404", mime: MimeType::Html };
-let route = ServableRouter::new()
-	.add_page("/", home_page)
-	.add_page("/about", about_page)
-	.add_page("/style.css", stylesheet)
-	.with_404(custom_404_page); // override default 404
-```
-
-# Features
-- `image`: enable image transformation via query parameters. This makes `tokio` a dependency. \
-	  When this is enabled, all `StaticAssets` with a valid mimetype can take an optional `t=` query parameter. \
-	  See the `TransformerEnum` in this crate's documentation for details.
-
-	When `image` is enabled, the image below...
-	```rust
-	# use servable::{ServableRouter, StaticAsset, mime::MimeType};
-	let route = ServableRouter::new()
-		.add_page(
-			"/image.png",
-			StaticAsset {
-				bytes: b"fake image data",
-				mime: MimeType::Png,
-			}
-		);
-	```
-	...may be accessed as follows:
-
-	```r
-	# Original image
-	GET /image.png
-
-	# Resize to max 800px on longest side
-	GET /image.png?t=maxdim(800)
-
-	# Crop to a 400x400 square at the center of the image
-	GET /image.png?t=crop(400,400,c)
-
-	# Chain transformations and transcode
-	GET /image.png?t=maxdim(800);crop(400,400);format(webp)
-	```
-
-
-- `htmx-2.0.8`: Include htmx sources in the compiled executable. \
-	  Use as follows:
-	```rust
-	# use servable::ServableRouter;
-	# #[cfg(feature = "htmx-2.0.8")]
-	let route = ServableRouter::new()
-		.add_page("/htmx.js", servable::HTMX_2_0_8)
-		.add_page("/htmx-json-enc.js", servable::EXT_JSON_1_19_12);
-	```
-
-
-
-## Caching and cache-busting
-
-Control caching behavior per servable:
-
-```rust
-use chrono::TimeDelta;
-use servable::HtmlPage;
-
-let page = HtmlPage::default()
-	.with_ttl(Some(TimeDelta::hours(1)))
-	.with_immutable(false);
-```
-
-Headers are automatically generated:
-- `Cache-Control: public, max-age=3600`
-- `Cache-Control: immutable, public, max-age=31536000` (for immutable assets)
