IE Filter on Rack
What?
-
Rack middleware that denies specified versions of IE.
-
Use the default template, a custom template or redirect users to another location.
Why?
-
Because progressive enhancement only goes so far.
How?
Install:
[sudo] gem install rack-denyie
Use:
require 'rack-denyie'
With default options: (Allows IE 7 or higher and displays the default template)
use Rack::DenyIE
With custom template and modified minimum version:
use Rack::DenyIE, {
:min_version => 8, # Allow IE 8 and higher
:template => "/full/path/to/your/template.html" # Custom HTML template
}
With redirection set (not well tested):
use Rack::DenyIE, {
:redirect_url => "http://browsehappy.com/"
}
With all options:
use Rack::DenyIE, {
:min_version => 6, # Minimum Version :: Allows IE 6 and higher
:template => '/full/path/to/your/template.erb', # Custom template :: ERB or HTML
:headline => 'Sorry, old browser alert!', # Replaces "Your version of Internet Explorer is not supported."
:site_name => "My Website" # Site Name :: Replaces the default "this site" with your site name.
}
Any key/value you pass in will be available to your ERB template.
use Rack::DenyIE, {
:my_key => "my value"
}
<%= @my_key %> #=> "my value"
Todo
-
Allow HAML templates
