Module: Roda::RodaPlugins::SharedVars

Defined in:

lib/roda/plugins/shared_vars.rb

Overview

The shared_vars plugin adds a shared method for storing shared variables across nested Roda apps.

class API < Roda
plugin :shared_vars
route do |r|
  user = shared[:user]
  # ...
end
end

class App < Roda
plugin :shared_vars

route do |r|
  r.on Integer do |user_id|
    shared[:user] = User[user_id]
    r.run API
  end
end
end

If you pass a hash to shared, it will update the shared vars with the content of the hash:

route do |r|
r.on Integer do |user_id|
  shared(user: User[user_id])
  r.run API
end
end

You can also pass a block to shared, which will set the shared variables only for the given block, restoring the previous shared variables afterward:

route do |r|
r.on Integer do |user_id|
  shared(user: User[user_id]) do
    r.run API
  end
end
end
