Five Minute Tutorial

The following assumes we have a working installation of Aerie in a directory called aerie-webapp

Inside aerie-webapp execute ant server. This will start an instance of Jetty, the web server that comes packed with Aerie, on port 8080.

Create the following file:

aerie-webapp/src/controllers/Hello.groovy :

import aerie.controller.Controller

class Hello extends Controller {

  public greeting

  def index() {
    greeting = "Hello World"
    render ("hello/index.html")
  }

}

The above code defines a Controller named Hello, with an Action named index. We are telling the index Action to render a Page - hello/index.html, so let's create it.

aerie-webapp/pages/hello/index.html :

<html>
  <head>
    <title>Hello</title>
  </head>
  <body>
    <h1><%= greeting %></h1>
  </body>
</html>

greeting is the public field we defined in the Hello Controller. All Controller fields that are declared public will be available to the views, i.e. the Pages.

Point a web browser to http://localhost:8080/hello and lo the results of our labour.

TDD Hello World In Aerie demonstrates our preferred, Test-First version of the above example.
