What is the recommended plugin type by test runners?

There is a gherkin parser called yadda. We have a hard time to figure out how to use karma with this parser to run our tests in browsers. We need to parse the feature files with yadda and run the step definitions using the info we extracted from the feature files. As far as I know (I am just trying to contribute) it is not possible to serialize the parsed gherkin files and transfer the info from nodejs to the browser, thus it is required to parse the files in the browser. Current solutions use jquery and ajax to get the feature files and parse them. I assume there is a much better and faster way to do that. What is the recommended way to list and parse the .cucumber files and use the extracted information to run the tests? In other terms which type of plugin should we use from the list?
