[nodejs] performance issue with express-validator

[Sebastian M Cheung]

After adding express-validator, the app slows down dramatically: why is 
that?

// mongoose config
require('./database');

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
//var expressValidator = require('express-validator');

var routes = require('./routes/index');
var users = require('./routes/users');
var form = require('./routes/form');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
//app.use(expressValidator);

[nodejs] How to pass value from one screen to another in Nodejs project?

[Sebastian M Cheung]

AlsoI created a simple test.js file inside NodeJS project, not sure where 
to start

I would also like to create app as per attached, with form validation and 
dropdown from JSON file
, once submitted, creates a new MongodB data row 

Also how to run test.js just by itself. Is there a REPL ?

[nodejs] Javascript and DataTables

[Sebastian M Cheung]

Following instructions how to use dataTables

http://www.datatables.net/examples/ajax/custom_data_flat.html

Following this example but where should I place my source data 
objects_root_array.txt in project directory? 

[
  {
"name": "Tiger Nixon",
"position": "System Architect",
"salary": "$320,800",
"start_date": "2011/04/25",
"office": "Edinburgh",
"extn": "5421"
  },
  {
"name": "Garrett Winters",
"position": "Accountant",
"salary": "$170,750",
"start_date": "2011/07/25",
"office": "Tokyo",
"extn": "8422"
  },...
]
I am using Flask, and I have placed in 

1. same location as my loadjson.js
2. top of project root directory data/objects_root_array.txt







loadjson.js

$(document).ready(function() {
$('#example').dataTable( {
"ajax": {
"url": "data/objects_root_array.txt",
"dataSrc": ""
},
"columns": [
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "start_date" },
{ "data": "salary" }
]
} );
} );
But it is always file cannot be found with a 404 status?
