express.json() middleware issue about swagger-node

[reverb-bot]

Hi! I'm a noob too :-) but I was just reading something yesterday that I
think might help with the recent express.js changes:
http://webapplog.com/migrating-express-js-3-x-to-4-x-middleware-route-and-other-changes

Good luck!

I'm having trouble following the
https://github.com/wordnik/swagger-node-express tutorial. I'm getting
the "Error: Most middleware (like json) is no longer bundled with
Express and must be installed separately" error, running node v0.10.22.
As per the instructions at
https://github.com/senchalabs/connect#middleware I have tried installing
https://github.com/expressjs/body-parser but now I am not sure how to
execute the |app.use(express.json() );| line. How does this work?

Thanks for your time, sorry for the noob post.

Very interesting, thanks for the link. There's a quick block about code conversion between 3.x and 4.x, so I've translated that into the init from the tutorial:

var express         = require("express")
  , logfmt          = require("logfmt")
  , EventSource     = require('eventsource')
  , http            = require('http')
  , fs              = require('fs')
  , url             = require('url')
  , cors            = require('cors')
  , bodyParser      = require('body-parser')
  , json            = require('json')
  , urlencode       = require('urlencode')
  , swagger         = require('swagger-node-express')
  , swmodels        = require('./swagger-models.js')
  ;

var app = express();
app.use(bodyParser() );
//app.use(express.json() );
//app.use(express.urlencoded() );
app.use( json() );
app.use( urlencode() );

Still throwing errors, investigation continues.

Turns out that you don't need to app.use() them! The errors I was working through were due to foreman and some module stuff. New (working) config looks like so:

var express         = require("express")
  , logfmt          = require("logfmt")
  , EventSource     = require('eventsource')
  , http            = require('http')
  , fs              = require('fs')
  , url             = require('url')
  , cors            = require('cors')
  , bodyParser      = require('body-parser')
  , json            = require('json')
  , urlencode       = require('urlencode')
  , swagger         = require('swagger-node-express')
  , models          = require('./swagger-models.js')
  ;

var app = express();
app.use(bodyParser() );
//app.use(express.json() );
//app.use(express.urlencoded() );
//app.use( json() );
//app.use( urlencode() );
