I want to create an ESN and save it in my database
I'm using Nodejs and Mongodb
you can find the model, route and controller that I have created, what I want is a simple POST API to add an ESN to my data base.
Models
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const esnSchema = new Schema({
esnName: {
type: String,
required: true,
},
esnEmail: {
type: String,
required: true,
},
esnLogo: {
data: Buffer,
contentType: String,
required: false,
}
})
module.exports = mongoose.model("Esn",esnSchema);
Controllers
const Esn = require('../models/esn');
// create new ESN
const createEsn = async (req, res) => {
if (!req.body.esnName) {
res.status(400).send({ message: "Content can not be empty!" });
return;
}
const esn = new Esn({
esnName: req.body.esnName,
esnEmail: req.body.esnEmail,
esnLogo: req.body.esnLogo
});
// Save Esn in the database
esn
.save(esn)
.then(data => {
res.send(data);
})
.catch(err => {
res.status(500).send({
message:
err.message || "Some error occurred while creating the esn"
});
});
};
module.exports = {
createEsn
};
Routes
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const esnSchema = new Schema({
esnName: {
type: String,
required: true,
},
esnEmail: {
type: String,
required: true,
},
esnLogo: {
data: Buffer,
contentType: String,
required: false,
}
})
module.exports = mongoose.model("Esn",esnSchema);
index.js
const express = require('express'),
cors = require('cors'),
swaggerUi = require('swagger-ui-express'),
swaggerDocument = require('./docs/swagger.json');
const Mongo = require('mongodb');
const { default: mongoose } = require('mongoose');
const mainRoutes = require('./routes/esn')
const app = express();
var url = "mongodb://127.0.0.1:27017/";
var databasename = "skills";
Mongo.MongoClient.connect(url).then((client) => {
console.log('Database connected');
const connect = client.db(databasename);
//const collection = connect.createCollection("esn");
console.log('Database: ', connect);
}).catch((err) => {
// Handling the error
console.log(err.Message);
})
app.use(cors());
app.use(express.json());
app.listen(3000, () => {
console.log('Listening on port 3000!');
});
app.get('/', (req, res) => {
res.send('Hello World');
});
app.use('/api/', mainRoutes);
app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument));
I expected to save an esn in the database but I have this error

I am trying to make this web page to upload the books and there links but it always show the following error
const mongoose = require('mongoose');
const BookSchema = new mongoose.Schema({
name: {
type: String,
required: true
},
authour: {
type: String,
required: true
},
discription: {
type: String,
},
link: {
type: String,
required: true
}
})
const Book = mongoose.model('books', BookSchema);
module.exports = Book ;
This is the schema I am using but it keeps showing

// await newBook.save();
console.log(newBook)

})
app.listen(3000, () => {
console.log("LISTENING ON PORT 3000")
})
I have tried to resolve it but it is always giving the same error I am not able to save this to the const newbook.even the console.log shows only the id not the form data
You have to set link.required to false or send it with your request body.
You need to change your post method in something like that,
const newBook = new books({
name:req.body.name,
authour:req.body.author,
discription:req.body.description,
link:req.body.link
})
I'm new in Express.js,MongoDb and mongoose, I have created HTTP request methods, but when running the Post method, nothing is done (nothing saved in the database), and postman still loading and it stops only when I cancel. I want to know what's wrong in my code, thank you .
router.post("/v1/department", async (req, res) => {
try {
const request = req.body
const department = new Department(request)
await department.save()
res.status(200).send(department)
} catch (error) {
res.status(500).send(error)
}
});
This is my model
const mongoose = require("mongoose");
const validator = require('validator')
const Department = mongoose.model('Department', {
name: {
type: String,
required: true,
}
,
email: {
type: String,
required: true,
trim: true,//
lowercase: true,
validate(value) {
if (!validator.isEmail(value)) {
throw new Error('Invalid email!')
}
}
}
,
createdBy: {
type: String,
default: 'SYS_ADMIN'
}
,
updatedBy: {
type: String,
default: 'SYS_ADMIN'
}
,
createdAt: {
type: Date
// ,
// default: Date.getDate()
}
,
updatedAt: {
type: Date
// ,
// default: Date.getDate()
},
isDeleted: {
type: Boolean,
default: false
}
})
module.exports = Department
This is the Index.js
const express = require("express");
const app = express()
const departmentRouter = require("../src/routes/department")
app.use(express.json())
app.use(departmentRouter)
//app.use('/', require('./routes/department'))
const port = process.env.PORT || 5000;//local machine port 3000
app.listen(port, () => (`Server running on local machine port ${port} 🔥`));
The connection to the database is :
const mongoose = require("mongoose");
//Connect to the local mongoDB database for testing the API localy
mongoose.connect('mongodb://127.0.0.1:27017/openemp-api-department', {
useNewUrlParser: true,
useCreateIndex: true
})
You're missing a few things here. Mongoose is never set up in the index.js so there is no connection to the database. This should help you follow step by step
Also in your router you're sending department1 which is never assigned.
If the link doesn't work or you need more information let me know.
For the latest version of Express which is (Express v4.16.0 and higher)
Use this in your server.js file: ----->
const express = require('express');
app.use(express.json());
app.use(express.urlencoded({
extended: true
}));
// For Express version less than 4.16.0
// ------------------------------------
const bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
otherwise your post request will give you error(like not recognizing any names etc)
so make sure to use these according to to express version

I am using Nodejs, MongoDB and Mongoose and while making a POST request I am getting error:

mongoose.connect(mongodb://localhost/subscribers, { useNewUrlParser: true })
const db = mongoose.connection

Use bodyParser above app.use(express.json())
Like : app.use(bodyparser.urlencoded({ extended : false }))
I tried to make a MEAN stack app, but my API fails to give my requested data.
server.js file:
const express = require("express");
const bodyparser = require("body-parser");
const mongoose = require('mongoose');
const dotenv = require('dotenv');
dotenv.config();
const port = process.env.PORT;
const dburi = process.env.DB_URI;
//Routes
const volcanoesRoute = require('./api/routes/volcano.routes');
mongoose.Promise = global.Promise;
mongoose.connect(
dburi,
{
useNewUrlParser: true,
useUnifiedTopology: true,
useFindAndModify: false,
useCreateIndex: true,
},
).then(
() => {
console.log('Connected to mongoDB');
},
(err) => console.log('Error connecting to mongoDB', err),
{ useNewUrlParser: true }
);
//Express app
const app = express();
app.use(bodyparser.json());
app.use(bodyparser.urlencoded({ extended: false }));
app.use('/api/vulcanoes', volcanoesRoute);
app.listen(port, () => {
console.log(`running at port ${port}`);
});
Routes file:
const express = require('express');
const volcanoController = require('../controllers/volcanoController');
const router = express.Router();
router.get('/getallvulcanoes', volcanoController.getAllVolcanoes);
module.exports = router;
Controller file:
const VolcanoSchema = require('../models/volcano.models');
const getAllVulcanoes = (req, res) => {
VolcanoSchema.find((err, results) => {
if (err) {
console.log(err);
res.status(500).json({message: err});
} else {
res.status(200).json(results);
}
});
};
module.exports = {getAllVolcanoes};
Model file
const mongoose = require('mongoose');
const VolcanoSchema = new mongoose.Schema({
Volcano_name:{
type: String,
},
Country:{
type: String,
},
Type:{
type: String,
},
Latitude:{
type: Number,
},
Longtitude:{
type: Number,
},
Elevation:{
type: Number,
},
});
module.exports = mongoose.model('Volcano', VolcanoSchema);
The thing is that i have a working example but most of the code is decrepitated... but it the respond is always giving me this
It would be nice if someone point out what i am doing wrong
EDIT: I switched to postgresql for my database hopefully this will work
You should fix the Controller (VulcanoSchema.find needs an empty object as parameter):
Controller file:
const VulcanoSchema = require('../models/vulcano.models');
const getAllVulcanoes = (req, res) => {
VulcanoSchema.find({}, (err, results) => {
if (err) {
console.log(err);
res.status(500).json({message: err});
} else {
res.status(200).json(results);
}
});
};
module.exports = {getAllVulcanoes};

I've tested your app and found that your database is hanging ...
Replace your database connection with this 😃:
const url = 'mongodb://localhost:27017/cinema';
mongoose.connect(url, {
useUnifiedTopology: true,
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false
}, console.log(`DB running on ${url}`));
