I'm working on a new project and I'm new with baucis for node.js. This is the code:
var name = 'order'
, baucis = require('baucis')
, controller = baucis.rest(name)
, paths = config.paths;
controller.request(function (req, res, next) {
if (req.isAuthenticated())
return next();
return res.send(401);
});
controller.documents(function (req, res, next) {
if (typeof req.baucis.documents === 'number') return next();
[...]
next();
});
And this is the error:
/Users/fil/[...]/order.js:31
controller.documents(function (req, res, next) {
^
TypeError: Object function router(req, res, next) {
router.handle(req, res, next);
} has no method 'documents'
at Object.<anonymous> (/Users/fil/[...]/order.js:31:12)
at Module._compile (module.js:456:26)

at /Users/fil/[...]/app.js:29:5
at Array.forEach (native)
at Object.<anonymous> (/Users/fil/[...]/app.js:27:57)
Any idea of the reason why this happends?
Hard to say 100% for sure, but I am guessing you are trying to use the controller.documents method with a new version of baucis, one that does not support this middleware stage.
If this is so, read about using outgoing stream transforms in the README.md file.

Hello I'm having a silly problem but I can't find the solution. When I try start my localhost I get an error saying this :
Error: Cannot find module 'passport'

}
I understand that it is not finding the passport.js file, I have checked the path name more than 10 times and I saw another problem where the guy had not installed the passport module, so I did that as well but it is still throwing the same error. This is what my index.js looks like :
var express = require('express');
var router = express.Router();
var Product = require('D:/Other/Projects/Code/Powershell/shopping-cart/models/product');
var csrf = require('csurf');
var passport = require('D:/Other/Projects/Code/Powershell/shopping-cart/config/passport.js');
var csrfProtection = csrf();
router.use(csrfProtection);
/* GET home page. */
router.get('/', function(req, res, next) {
Product.find(function(err, docs) {
var productChunks = [];
var chunkSize = 3;
for (var i = 0; i < docs.length; i += chunkSize) {
productChunks.push(docs.slice(i, i + chunkSize));
}
res.render('shop/index', { title: 'Shopping Cart', products: productChunks });
});
});
router.get('/user/signup', function (req, res, next) {
res.render('user/signup', {csrfToken: req.csrfToken()});
});
router.post('/user/signup', passport.authenticate('local.signup', {
successRedirect: '/user/profile',
failureRedirect: '/user/signup',
failureFlash: true
}));
router.get('/user/profile', function(req, res, next) {
res.render('user/profile');
});
module.exports = router;
Any help would be appreciated, thanks! Also , I have another problem , can I post another question in like one hour? (is it allowed to have more than 1 questions posted?)

Here is my ..models/category(category schema)
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const CategorySchema = new Schema({
name: { type: String, unique: true, uppercase: true}
});
module.exports = mongoose.model('Category', CategorySchema);
add-category Route in admin.js file
const router = require('express').Router();
const Category = require('..models/category');
// add-category route
router.get('/add-category', function(req, res, next) {
res.render('admin/add-category', { message: req.flash('success') });
});
router.post('/add-category', function(req, res, next) {
var category = new Category();
category.name = req.body.name;
category.save(function(err) {
if (err) return next(err);
req.flash('success', 'Successfully added a category');
return res.redirect('/add-category');
});
});
Here also server.js file to include the category
const Category = require('./models/category');
app.use(function(req, res, next) {
Category.find({}, function(err, categories) {
if (err) return next(err);
res.locals.categories = categories;
next();
});
});
const adminRoutes = require('./routes/admin');
app.use(adminRoutes);
when i run my server or route the add-category url then show module.js:549 throw err; this problem.
Here is my problem details and i check my code different times.
Then how can i solve this problem.
Seems to me that you forgot a /:
require('..models/category');
require('../models/category');
This is why ..models/category throws an error. From a general point of view, when require can't find a local module, don't "check the code", just check where the file is, and what path you wrote, it's always one or the other. ;)
i am learning node and i have two get request in my index.js
var express = require('express');
var router = express.Router();
router.get('/', function(req, res, next) {
res.status(200)
.json({
status: 'success',
message: 'Welcome to EverestApi!'
});
});
var db = require('./queries');
router.get('/api/users', db.getAllUsers);
router.get('/api/pref', db.getAllPref);
module.exports = router;
and my query.js
var promise = require('bluebird');
var options ={
promiseLib : promise
};
var pgp = require('pg-promise')(options);
var db = pgp({
host: 'localhost',
port: 5432,
database: 'nari',
user: 'postgres',
password: 'pes'
});
function getAllUsers(req, res, next) {
db.any('SELECT * FROM office.users')
.then(function (data) {
res.status(200)
.json({
status: 'success',
data: data,
message: 'Retrieved all users'
});
})
.catch(function (err) {
return next(err);
});
}
function getAllPref(req, res, next){
db.any('SELECT * FROM core.preferences')
.then(function(data){
res.status(200)
.json({
status: 'success',
data : data,
message : 'Retrieved all preferences'
});
})
.catch(function(err){
return next(err);
});
}
module.exports ={getAllUsers: getAllUsers};
module.exports={getAllPref : getAllPref};
I have two GET Action in here.One getAllUsers() and another getAllPref().Starting the server gives error .

in your query.js
export the functions in a object
module.exports = {
getAllUsers: getAllUsers,
getAllPref: getAllPref,
}
I want to add a script in app.js file here is the code:
app.helpers({
renderScriptsTags: function (all) {
if (all != undefined) {
return all.map(function(script) {
return '<script src="/javascript/' + script + '"></script>';
}).join('\n ');
}
else {
return '';
}
}
});
app.dynamicHelpers({
scripts: function(req, res) {
return ['canvasjs.min.js'];
}
});
while executing its give me an error shown below:
app.helpers({

As your error is showing app does not have helper funtion. Memeber functions of app are listed here http://expressjs.com/en/api.html
if you want to use helpers you will have to create them explicity like
//helper.js
module.export = function(){
// Your logic here
};
//usage
var helper = require('./relative/path/to/helper');
var getValueFromHelper = helper();
hope it helps :)
I am new to nodeJS. I am trying to use different middlewares with connect middleware.
this is my code:
var connect = require('connect');
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var app = connect()
.use(connect.bodyParser())
.use(connect.cookieParser('tobi is a cool ferret'))
.use(function(req, res){
console.log(req.cookies);
console.log(req.signedCookies);
res.end('hello\n');
}).listen(3000);
I have installed every middleware through npm.
I am getting this error while running this file.
/home/dipesh/Desktop/temp/temp.js:5
.use(connect.bodyParser())
^
TypeError: Object function createServer() {
function app(req, res, next){ app.handle(req, res, next); }
merge(app, proto);

app.route = '/';
app.stack = [];
return app;
} has no method 'bodyParser'

Any suggestions?
.use(bodyParser())
not
.use(connect.bodyParser())
You have required body-parser, but then never used it.
You are essentially doing
var a = function(){};
var b = {};
b.a();
which is not correct because b has not 'a' property.
