Swiftype snippet in CoffeeScript

swiftype.coffee

# Swiftype relies on the creation of the global variable window.Swiftype.
# Due to CoffeeScript's top-level function safety wrapper, the snippet requires
# modification in order to make the Swiftype variable break free of lexical
# scope hell.



# I would love some feedback on whether the existential operator is a better
# choice than simply using `or`
Swiftype = window.Swiftype ? {}
Swiftype.key = 'api key here'
Swiftype.inputElement = '#st-search-input'
Swiftype.resultContainingElement = '#st-results-container'
Swiftype.attachElement = '#st-search-input'
Swiftype.renderStyle = 'overlay'
