Module | Sinatra::Reloader |
In: |
lib/sinatra/reloader.rb
|
Extension to reload modified files. Useful during development, since it will automatically require files defining routes, filters, error handlers and inline templates, with every incoming request, but only if they have been updated.
To enable the reloader in a classic application all you need to do is require it:
require "sinatra" require "sinatra/reloader" if development? # Your classic application code goes here...
To enable the reloader in a modular application all you need to do is require it, and then, register it:
require "sinatra/base" require "sinatra/reloader" class MyApp < Sinatra::Base configure :development do register Sinatra::Reloader end # Your modular application code goes here... end
By default, the reloader is only enabled for the development environment. Similar to registering the reloader in a modular application, a classic application requires manually enabling the extension for it to be available in a non-development environment.
require "sinatra" require "sinatra/reloader" configure :production do enable :reloader end
You can refine the reloading policy with also_reload and dont_reload, to customize which files should, and should not, be reloaded, respectively.
Simply call the methods:
require "sinatra" require "sinatra/reloader" if development? also_reload '/path/to/some/file' dont_reload '/path/to/other/file' # Your classic application code goes here...
Call the methods inside the configure block:
require "sinatra/base" require "sinatra/reloader" class MyApp < Sinatra::Base configure :development do register Sinatra::Reloader also_reload '/path/to/some/file' dont_reload '/path/to/other/file' end # Your modular application code goes here... end

When the extension is registered it extends the Sinatra application klass with the modules BaseMethods and ExtensionMethods and defines a before filter to perform the reload of the modified files.
