API

erb(opts)

opts is a simple JSON object with these properties:

• timeout (optional, integer) - number of milliseconds (defaults to 5000) to wait for the template evaluation to finish before terminating with error
• data (optional, object) - an object that contains these properties:
  • fields (optional, object) - the keys of this object are instance variable names to be used in the ERB template and values are the values of the instance variables
  • values (optional, object) - the keys of this object are variable names to be used in the ERB template and values are the values of the variables
  • functions (optional, object) - the keys of this object are function names to be used in the ERB template and values are special arrays - the items match the function call arguments with the last item being the value returned by the function when called with these arguments.
• template (required, string) - the ERB template to be compiled
