Hi, building on the work by Bas Couwenberg back in 2015 I have packaged node-socket.io-parser, see the ITP I am CC-ing and the repo: https://anonscm.debian.org/git/pkg-javascript/node-socket.io-parser.git
Besides node-socket.io and closure-util mentioned above in the ITP, this is also a requirement for packaging etherpad-lite (https://bugs.debian.org/576998). Please someone more experienced than me review it and if it's OK sponsor its upload. Thanks, Paolo
