A Rack middleware to make URLs in one-page webapps easier.
In a couple of recent projects, I've needed to avoid full page refreshes as much as possible. In the first, I wanted to keep an embedded music player active while the user was browsing. In the second, I just wanted fancier transitions between pages.
It's possible to do this in an ad-hoc way, but I very quickly got tired of hacking things together. Enter Onesie.
Onesie congealed from these requirements:
I want a one-page web app,
But I want the back button to work,
And I want search engines to still index some stuff,
And I (mostly) don't want to change the way I write a Rails/Sinatra app.
If someone visits example.org/meta/contact, I want them to be redirected to example.org/blah/#/meta/contact, but after the redirection I still want the original route to be rendered for search engine indexing, etc.
When Onesie gets a request, it looks to see if under your preferred one-page app path (“blah” in the example above). If it's not, Onesie sets the current request's path in the session and redirects to your app path.
If a request is under the one-page app path, the “real” request's path is retrieved from the session and used for subsequent routing and rendering. This means that, as above, a request for
Will be redirected to
But still render the correct action in the wrapped app, even though URL fragments aren't passed to the server.
This is a terrible explanation. I'll write a sample app or something soon.
require "onesie" # in config.ru, after any session support use Onesie # in Rails unless Rails.env.test? config.middleware.insert_before ActionDispatch::Flash, "Onesie" end
$ gem install onesie
