Things I wish I knew about MongoDB a year ago I’ve used MongoDB for over a year at scale at both Heyzap and Bugsnag and I’ve found it to be a very capable database. As with all databases, there are some gotchas, and here is a summary of the things I wish someone had told me earlier. Selective counts are slow even if indexed For example, when paginating a users feed of activity, you might see something like, In MongoDB this count can take orders of magnitude longer than you would expect. Inconsistent reads in replica sets When you start using replica sets to distribute your reads across a cluster, you can get yourself in a whole world of trouble. This is compounded if you have performance issues that cause the replication lag between a primary and its secondaries to increase to minutes or even hours in some cases. You can control whether a query is run on secondaries and also how many secondaries are replicated to during the insert, but this will affect performance and could block forever in some cases! Mongo’s BSON ID is awesome Profiler
UK Web Archive BOWER React Modules · nodejs/node-v0.x-archive Wiki This page is deprecated. Feel free to add to it, but be advised that it is, at best, a faded relic of Node modules that were written before npm was a dominant force in the Node.js ecosystem. It is not all that useful any more. If you are a newcomer, it can be handy to at least get a starting point. So, this list is long enough to be intimidating, but still only captures a tiny sliver of the Node.js modules you can use with your program. Search for modules with npmjs.org, node-modules, and nipster. The archaic contents of this once-useful page now follow. Adding to this page When you add a framework to this page, have a look at how others have done so, it should be a single item, with a link to the project's source code, and a short description (one line after formatting has been applied). If you see a module without a description, feel free to edit the page and add it in, any contributions are appreciated.

Alexander Luksidadi's Blog » ExpressJS without Jade? Use Underscore template! Many of you must have felt like a burden knowing that Express recommended you to learn another template language (Jade). Don’t worry, you can code all your templates on HTML using underscoreJS! Oh yay? Let’s take a look on how you implement that on your express app. First install express package, create your express app: $ npm install -g express $ express . Install your underscore package $ npm install -d underscore If you edit Now, all you need to do is, to comment out 1 line and register underscorejs: Now, go to routesindex.js : $ vi routes/index.js Change the template name from ‘index’ to ‘index.html’: Next, go to views directory and create layout.html And last, still in views directory, create another file called index.html And there you go.. you can write your HTMl code in peace =)
