Group-level transactional support in javascript using promises.
View transaction.js
Q = require('Q');
* Store a promise for each `group` of function calls; the existence of a
* promise for a given key indicates a lock on that group, and subsequent
* calls in that group are delayed until that promise is resolved. After the
* last call is complete, the lock (i.e. key) is cleared.

Make node's winston logger print stack traces
View winstonConfig.js
// Extend a winston by making it expand errors when passed in as the
// second argument (the first argument is the log level).
function expandErrors(logger) {
var oldLogFunc = logger.log;
logger.log = function() {
var args =, 0);
if (args.length >= 2 && args[1] instanceof Error) {
args[1] = args[1].stack;
return oldLogFunc.apply(this, args);
You can’t perform that action at this time.
