## Slim Play App [![Build Status](https://travis-ci.org/lloydmeta/slim-play.svg?branch=master)](https://travis-ci.org/lloydmeta/slim-play)

Wanna build a really, really slim Play project?

This project demonstrates how you can easily build a non-blocking, threadsafe, and fast Play app without having to

use the default `routes` file. The end-result should be familiar territory for people who are used to the simplicity of Sinatra/Bottle

but want to take advantage of Scala's concurrent, type-safe and scalable nature.

### Templates

In case you want to get up and running right away, use the following Slim-Play templates:

For [Giter8](https://github.com/n8han/giter8): `$ g8 lloydmeta/slim-play`

### How to run

1. Git clone this project or use [a template](#templates)

2. `sbt run` from the project's root directory

3. Open a browser and hit:

  - [Hello $name endpoint](http://localhost:9000/hello/beachape)

  - [Async Sqrt calculator](http://localhost:9000/sqrt/1764)

### How it was built

All I did was:

1. Use `sbt new` to generate a new Play app (`$ sbt new playframework/play-scala-seed.g8 --name=slim-play`)

2. Delete the auto-generated controller, public, and view directories (won't be using them)

3. Create a `AppLoader.scala` file in the `./app` directory, which holds an ApplicationLoader and the router, which is

  super simple:

  ```scala

  val router = Router.from {

    case GET(p"/hello/$to") => Action {

      Ok(s"Hello $to")

    }

    /*

     Use Action.async to return a Future result (sqrt can be intense :P)

     Note the use of double(num) to bind only numbers (built-in :)

     */

    case GET(p"/sqrt/${double(num)}") => Action.async {

      Future {

        Ok(Math.sqrt(num).toString)

      }

    }

  }

  ```

4. Add `play.application.loader=AppLoader` to `./conf/application.conf` so that Play knows to load our custom app (that

  contains our simple router)
