FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

First couple things I thought about when migrating after reading the docs

So migrating my existing app wasn't as troublesome as I originally thought. First thing I did was take a look at my router and routes and figure try to make a mental model of all the files where I had nested routes in the existing app because those components/containers will contain {this.props.children}. So I need to replace those with the nested <Match /> components.

So just to give an example:

In v2:

<Router history={history}>
  <Route path="/" component={App}>

Installing Cassandra on Mac OS X

Install Homebrew

Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

var db = mongoose.connect('mongodb://localhost:27017/DB'); 

// In middleware
app.use(function (req, res, next) {

  // action after response
  var afterResponse = function() {
   logger.info({req: req}, "End request");

    // any other clean ups
