Hi everyone! I am looking for a js expert who has experience with node.js. Prefer someone who has worked on and contributed code to the Mozilla Popcorn Maker, Butter ,tool ([login to view URL]). I want you to make a plugin( I give the details when we meet) for that tool and show me how you make that to communicate with other parts of that tool. In your reply please let me know If you have added anything to the butter before. Thank you :)
