Express has no method configure error
Tom in his blog post new-features-node-express-4 provides examples of how to convert from using app.configure in express version 3.x to removing it in express version 4.0.
For convenience I added the code example below.
Version 3.x
// all environmentsapp.configure(function(){ app.set('title', 'Application Title');})// development onlyapp.configure('development', function(){ app.set('mongodb_uri', 'mongo://localhost/dev');})// production onlyapp.configure('production', function(){ app.set('mongodb_uri', 'mongo://localhost/prod');})Version 4.0
// all environmentsapp.set('title', 'Application Title');// development onlyif ('development' == app.get('env')) { app.set('mongodb_uri', 'mongo://localhost/dev');}// production onlyif ('production' == app.get('env')) { app.set('mongodb_uri', 'mongo://localhost/prod');}
The configure method has been removed from express as of version 4.0.0 (including 4.0.0-rc2). See the changelog at https://github.com/strongloop/express/blob/master/History.md#400--2014-04-09
