1. A Simple Plan
   Building a small web API in something

2. The Reason
   I'm hosting a get-together in a few weeks* for folks
   to experiment with non-typical programming languages.
   I wanted to experiment as well.
   * - More on this later.

3. The API
   GET /attendees - All the attendees
   POST /attendees - Create an attendee
   GET /attendee/:id - Get a single attendee
   GET /languages - Get all the languages
   GET /languages/:lang - All the attendees interested

4. The options
   » Crystal & Kemal
   » Rust & Iron
   » Swift & Vapor
   » A few other attempts in Elixir, Haskell ... but
   let's not talk about those

5. Crystal
   It's like compiled, statically-typed Ruby. With type-
   inference.
   Most Ruby exercism solutions can move over with just
   a few tweaks.
   Love.
   puts "Hello World!"

6. Kemal
   Sinatra, but in Crystal.
   require "kemal"
   get "/" do
   "Hello World!"
   end
   This might become a theme.

7. Downfall
   » This thing is young and everything is in a
   perpetual state of semi-broken right now.
   » As a Rubyist, writing it really isn't a stretch at
   all.
   » Did I mention everything is kinda broken?

8. Rust
   A systems programming language sponsored by Mozilla.
   Also statically-typed and compiled with type-
   inference.
   fn main() {
   println!("Hello World!");
   }

9. Iron
   Um. Kinda Sinatra in Rust.
   extern crate iron;
   use iron::prelude::*;
   use iron::status;
   fn main() {
   fn hello_world(_: &mut Request) -> IronResult {
   Ok(Response::with((status::Ok, "Hello World!")))
   }
   let _server = Iron::new(hello_world).http("localhost:3000").unwrap();
   println!("On 3000");
   }

10. Downfall
    » Docs. Ugh. Docs, man.
    » Big, big jump to persistence ... because, docs.
    » unwrap() literally everywhere.

11. Swift
    Not just for phones! Compiled, type-inference ... but
    closures!
    print("Hello, world!")

12. Vapor
    A web framework for running Swift on the server -
    including Linux servers. And Heroku!
    import Vapor
    import HTTP
    let drop = Droplet()
    drop.get("hello") { request in
    return "Hello, world!"
    }
    let port = drop.config["app", "port"]?.int ?? 80
    drop.serve()

13. Bonuses
    » Better docs than most.
    » Built-in ORM - with relationships!
    » Built-in deployment pipeline to Heroku
    » Type-safe routing(!)

14. Downsides
    » Moving target
    » vapor new includes a lot of garbage
    » MySQL only at the moment (unless you roll your
    own)
