Sinatra (C) 2007 By Blake Mizerany
|
|
|
|
= Classy web-development dressed in a DSL
|
|
|
|
== Install!
|
|
|
|
sudo gem install sinatra -y
|
|
|
|
== Use!
|
|
|
|
I'm going to move quick. I'll let you drool at your own pace.
|
|
|
|
- Create a file called lyrics.rb (or any name you like)
|
|
|
|
- Add
|
|
require 'rubygems'
|
|
require 'sinatra'
|
|
|
|
- Run (yes, with just ruby)
|
|
% ruby lyrics.rb
|
|
== Sinata has taken the stage on port 4567!
|
|
|
|
- Take a moment and view the default page http://localhost:4567. Go ahead and bask in it's glory.
|
|
|
|
* Notice:
|
|
* It didn't create any page to show you that default page (just a cool thing to see, that's all)
|
|
* There was nothing generated other than a log file
|
|
* Sinatra is a really cool name for a web-framework that's a DSL
|
|
|
|
- Modify lyrics.rb by adding:
|
|
|
|
get '/' do
|
|
'Hello World'
|
|
end
|
|
|
|
- Refresh (no need to restart Sinatra):
|
|
|
|
http://localhost:4567
|
|
|
|
- Modify again (then refresh):
|
|
|
|
get '/' do
|
|
<<-HTML
|
|
<form action='/' method="POST">
|
|
<input type="text" name="name" />
|
|
<input type="submit" value="Say my name!" />
|
|
</form>
|
|
HTML
|
|
end
|
|
|
|
post '/' do
|
|
"Hello #{params[:name] || 'World'}!"
|
|
end
|
|
|
|
- Homework:
|
|
|
|
Use the Sinatra::Erb::EventContext or Sinatra::Haml::EventContext to do the same. Do them inline and as template files.
