**Miso** is a small [isomorphic](http://nerds.airbnb.com/isomorphic-javascript-future-web-apps/) [Haskell](https://www.haskell.org/) front-end framework featuring a virtual-dom, diffing / patching algorithm, event delegation, event batching, SVG, Server-sent events, Websockets, and an extensible Subscription-based subsystem. Inspired by [Elm](http://elm-lang.org/), [Redux](http://redux.js.org/) and [Bobril](http://github.com/bobris/bobril). `IO` and other effects (like `XHR`) can be introduced into the system via the `Effect` data type. *Miso* makes heavy use of the [GHCJS](https://github.com/ghcjs/ghcjs) FFI and therefore has minimal dependencies.

## Getting Started
```haskell
{-# LANGUAGE RecordWildCards #-}
module Main where
import Miso
type Model = Int
main :: IO ()
main = startApp App {..}
where
model = 0
update = updateModel
view = viewModel
events = defaultEvents
subs = []
updateModel :: Action -> Model -> Effect Model Action
updateModel AddOne m = noEff (m + 1)
updateModel SubtractOne m = noEff (m - 1)
data Action
= AddOne
| SubtractOne
deriving (Show, Eq)
viewModel :: Int -> View Action
viewModel x = div_ [] [
button_ [ onClick AddOne ] [ text "+" ]
, text (show x)
, button_ [ onClick SubtractOne ] [ text "-" ]
]
```
