I want to write data to mongodb Database using node.js - angularjs

Question

Right now i am writing data to json file and getting that back to html page to display. Now i want to do same with mongodb Database. I have tried something but, it doesn't working.
app.get('/', function(req, res){
url = 'http://www.amazon.in/Sony-Xperia-Z3-Copper-32GB/dp/B010V448ZC/ref=pd_rhf_se_s_cp_6?ie=UTF8&dpID=419rmomR%2BjL&dpSrc=sims&preST=_SL500_SR135%2C135_&refRID=19RT23W7T48Z99XNT6GK';
request(url, function(error, response, html){
if (!error) {
var $ = cheerio.load(html)
var json = {Product_Name : "", Brand : "", Color : "", Image : "", Price : "", Rating : ""};
var P_name = $('#title').children().text();
var brand = $('#brand').text();
var color = $('.a-row').find('span.selection').text();
var price = $('#price').find('span.a-size-medium').text();
var rating = $('#averageCustomerReviews').find('span.a-icon-alt').text();
var image = $('.imgTagWrapper').children().attr('src');
/*json.Product_Name = P_name;
json.Brand = brand.trim();
json.Color = color.trim();
json.Price = price.trim();
json.Rating = rating.trim();
json.Image = image.trim();
fs.writeFile('output.json', JSON.stringify(json, null, 4), function(err){
console.log('File successfully written! - Check your project directory for the output.json file');
})*/
var insertDocument = function(db, callback) {
db.collection('proInfo').insertOne( {
"Product_Name": P_name,
"Brand":brand,
"Color":color,
"Price":price,
"Rating":rating,
"Image":image
}, function(err, result) {
assert.equal(err, null);
console.log("Inserted a document into the proInfo collection.");
callback(result);
});
};
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
insertDocument(db, function() {
db.close();
});
});
res.send('Check your console!')
} else {
console.log("We’ve encountered an error: " + error);
}
})
})
It shows some error in console.log
D:\Hemanth\Node Js\web scraper\node_modules\mongodb\lib\url_parser.js:20
throw new Error('invalid schema, expected mongodb');

Error: invalid schema, expected mongodb
at module.exports
Can anybody help me to fix this issue?

Answer 1

Use module export in your node js routes and define the method inside the module.export as mentioned below :
module.export {}
and then call the method, apply routes in the server.js under node application :
erc(app,
{
controllers: __dirname + '/routes',
routes:{'/methodnametobecalled': { action: 'routesfilename#methodname'}
}
});

Initialize Mongoose and Schema
var mongoose = require('mongoose');
mongoose.connect('mongodb://YOURVALUES.mongolab.com:11111/NAME');
var schema = new mongoose.Schema({ name: 'string', account: 'string', date: 'string' });
var accountz = mongoose.model('accountz', schema);
Create
var small = new accountz({
name: "SAMZ",
account: "Monthly",
date: "29/12/2015"
});
small.save(function (err) {
if (err){
console.log("Error in Save");
}else{
console.log("Save Sucessfully");
}
});
Read
accountz.find().exec(function(err, data){
if (err){
console.log("Error in Reading");
}else{
console.log("The value = " + data);
}
});
Update
accountz.findOne({ "_id": "0023"}, function (err, doc){
doc.name = editObj.name;
doc.account = editObj.account;
doc.date = editObj.date;
doc.save(function (err) {
if (err){
console.log("Error in Updating");
}else{
console.log("Updated Sucessfully");
}
});
});
Delete
accountz.remove({ "_id": "0023"}).exec(function(err, data){
if (err){
console.log("Error in Deleting");
}else{
console.log("Deleting Sucessfully");
}
});
