this is my mean code.
const express = require('express');
const router = express.Router();
const passport = require('passport');
const jet = require('jsonwebtoken');
const Contact = require('../models/contacts');
// retrieving Data
router.get('/contacts',(req,res,next)=>{
// res.send('Retriving the contact list');
console.log('contacts page');
Contact.find(function(err, contacts){
res.json(contacts);
})
});
// to add the content
router.post('/contact',(req, res, next)=>{
// logic to add contact
let newContact = new Contact({
first_name: req.body.first_name,
last_name: req.body.last_name,
email_id: req.body.email_id,
password: req.body.password
});
Contact.addRegistry((err, contacts)=> {
if(err) {
res.json({msg:'faild to add register'});
}
else{
res.json({msg:'registry added sucessfully'});
}
});
});
// to delete the content
router.delete('/contact/:id',(req, res, next) =>{
// logic to delete contact
Contact.remove({_id:req.params.id}, function(err, result){
if(err){
res.json(err);
}
else {
res.json(result);
}
});
})
module.exports = router;
the above file is route.js. the below code is from contact.js
// Database code.
var express = require('express');
var app = express();
var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');
// database schaema
var ContactSchema = new mongoose.Schema({
first_name: String,
last_name: String,
id: String,
location: String,
profile_picture_url: String,
email_id: String,
phone: String,
job_title: String,
company: String,
education: String,
password: String,
savedjobslist: {
title: [],
subtitle: []
},
appliedjobslist: {
title: [],
subtitle: []
},
failedjobslist: {
title: [],
subtitle: []
}
});
const Contact = module.exports = mongoose.model('Contact', ContactSchema);
module.exports.getUserById = function(id,callback) {
Contact.findById(id,callback);
}
module.exports.getUserById = function(username,callback) {
const query = {username: username}
Contact.findOne(query,callback);
}
module.exports.addRegistry = function(newContact,callback) {
bcrypt.genSalt(10, (err,salt) => {
bcrypt.hash(newContact,salt, (err,hash) => {
if (err) {
console.log(err);
}
newContact.password = hash;
newContact.save(callback);
});
});
}
I'm trying to post the data from postman it is shoing the error as
"there was error connecting to http://localhost:3000/api/contact "
and in the command prompt it is showing the error as

You have an issue here:
bcrypt
for generating is throwing an error because of wrong parameters. You can't pass object (newContact) to bcrypt
.
Try to generate a hash using the following code:
const salt = bcrypt.genSaltSync(10);
const hashedPassword = bcrypt.hashSync(password, salt);
You can use pre save function of mangoose to generate hashedPassword while storing this. Personally, I don't prefer as this adds new check everytime you save the object
find() takes query as an argument to search all pass {}
Contact.find({},function(err, contacts){
res.json(contacts);
})
Contact.addRegistry waits newContact as first parameter, but you do not pass it on your route.js
I think you want to do something like this
ContactSchema.pre('save', function(next) {
const user = this;
// generate a salt
bcrypt.genSalt(10, function(err, salt) {
if (err) return next(err);
// hash your password
bcrypt.hash(user.password, salt, function(err, hash) {
if (err) return next(err);
// store hash on the password field
user.password = hash;
next();
});
});
});
