Validation of Inputs in the Node ExpressJS Framework

I am using node 0.10.8 and expressJS 3.2.5.

Recently, I installed the express-validator package:

npm install express-validator

In my app.js file:

var express = require('express')
  , i18n = require('i18next')
  , routes = require('./routes')
  , user = require('./routes/user')
  , http = require('http')
  , path = require('path');
  , expressValidator = require('express-validator');

....  

app.set('port', process.env.PORT || 3000);
app.use(i18n.handle);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(expressValidator);
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));

...

The issue I have encountered is that no page will load in the browser. Interestingly, when I remove the line

expressValidator = require('express-validator')
and also the line app.use(expressValidator);, the application starts working properly again.

Could there be a conflict with the version or another module that I am using?

Thanks for any help!

Answer №1

expressValidator is a unique middleware function.

To utilize its functionality, you should include the following line of code:

app.use(expressValidator());
