node.js-domains

How can I create Express/Connect middleware which wrap each request in its own domain? This set of slides on Speaker Deck gives a succinct overview: Domains in node 0.8 Express middleware code from the slides: var createDomain = require('domain').create; app.use(function(req, res, next) { var domain = createDomain(); domain.on('error', function(err) { // alternative: next(err) res.statusCode = 500; res.end(err.message + '\n'); domain.dispose(); }); domain.enter(); next(); }); UPDATE: The approach described below has been implemented in the connect-domain NodeJS module, which can be used in

I want to use Node.js Domains to catch exceptions. It is working so far, but there is one place I can't get domains to catch the exception. exception2 in the callback is caught and handled in the domain.on('error') handler, but exception1 is not caught. The odd thing is that when exception1 is thrown, it doesn't shutdown Node like I would expect. Here is my example app: var domain = require('domain'); var request = require('request'); var express = require('express'); var serverDomain = domain.create(); serverDomain.on('error', function(err) { console.log("Server Domain Error: " + err); });
