This tutorial will teach you how to make Crud Application using Nodejs Mongodb Cloud Crud Application.
Create the Node Js Project Type on type command prompt
npm init
and press enter key.after that you have the fill configation of project.after done stuff you
will get the package.json file.
after that you have to install the following dependencies
npm i Express
npm i body-parser
npm i mongoose
After done the stuff you have to create the file index.js
index.js
const express = require("express")
const mongoose = require("mongoose")
var routers = require('./routes/routes');
const bodyParser = require("body-parser")
const app = express()
const port = 5000;
const mongodatabaseURL ="mongodb+srv://kobiram:mongoabc@cluster0.cqfkrbj.mongodb.net/?retryWrites=true&w=majority";
mongoose.connect(mongodatabaseURL,{
useNewUrlParser: true,
useUnifiedTopology: true
});
const connection = mongoose.connection
app.listen(port,()=>{
console.log("Server is running port" +port);
})
connection.once("open",()=>{
console.log("MongoDb Connected!!!......")
});
app.use(bodyParser.json());
app.use(routers);
routes.js
const express = require("express")
const router = express.Router();
var studentModel = require('../src/student/studentModel');
//Add Rrcords
router.post('/student/create', async(req,res)=>{
const student = new studentModel(req.body)
try{
await student.save();
res.status(201).send(
{
"status" : true,
"message" : "Student Created!!!!!!!!!!!!!!!!"
});
}
catch(error)
{
res.status(400).send(error);
}
});
//View Records
router.get('/students', async(req,res)=>{
try{
const students = await studentModel.find({});
res.send(students);
}
catch(error)
{
res.status(400).send(error);
}
});
//find records
router.get('/students/:id', async(req,res)=>{
try{
const _id = req.params.id;
const students = await studentModel.findById({_id});
if(!students)
{
return res.status(404).send();
}
return res.status(200).send(students);
}
catch(error)
{
res.status(400).send(error);
}
});
//update records
router.patch('/students/:id', async(req,res)=>{
try{
const _id = req.params.id;
const body = req.body;
const updatestudents = await studentModel.findByIdAndUpdate(_id,body,{new:true});
if(!updatestudents)
{
return res.status(404).send();
}
res.status(201).send(
{
"status" : true,
"message" : "Student updateddd!!!!!!!!!!!!!!!!"
});
}
catch(error)
{
res.status(400).send(error);
}
});
//delete records
router.delete('/students/:id', async(req,res)=>{
try{
const _id = req.params.id;
const deletestudents = await studentModel.findByIdAndDelete(_id);
if(!deletestudents)
{
return res.status(404).send();
}
res.status(201).send(
{
"status" : true,
"message" : "Student Deletedd!!!!!!!!!!!!!!!!"
});
}
catch(error)
{
res.status(400).send(error);
}
});
