This tutorial will teach you crud application using angularjs node js mongodb.node js mongodb crud along with angular is famous full stack development in the future because very easy step make restful api we will start from the node js angular install process to make the restfulapi project along with video tutorial so you easy to learn it i attached the video below of articles.

nodejs express angular Learn Learn

First Step What you have to do is you to divide the Front-End and Back-End.

Front-End – Angular JS

BackEnd – Node JS

Create the folder myprojects. inside the folder Frond end project  you maintaining with the separate folder.
Backend project you maintaining with the separate folder.

Install Node JS

Create  a new Project type  the command on the command prompt.

Type the Command on Console.

npm init

Then open the project in to the VS Code Editor by typing the following command

code .

Install the Express Server as back end server

npm i express

npm i body-parser

npm i mongoose

First Create the Application server.js which manage the ports and libraries and database connection of the project. We have created the database on mongodb atlas Cloud database service which name test.attached the db connection below.

index.js

const express = require("express")
const mongoose = require("mongoose")
var routers = require('./routes/routes');
const bodyParser = require("body-parser")

const app = express()
const cors = require('cors');
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(cors());
app.use(bodyParser.json());
app.use(routers);

After that you can run the server type by the following command.

node index.js

MongoDb Connected

after that make the new folder route and inside the folder create the page route.js. route.js page which use to manage the all the restapis related to crud operations.

Create Routes

const express = require("express")
const router = express.Router();
var studentModel = require('../src/student/studentModel');


//Add Records
router.post('/student/create',auth, async (req, res) => {
    try {
      const student = new studentModel(req.body);
      await student.validate(); // Validate the input data
  
      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.student._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);
 
    }
 });


 router.post('/students/logout',auth, async(req,res)=>{
   
    try{
            req.student.tokens = req.student.tokens.filter((token)=>{
                return token.token !== req.token;
            })

            await req.student.save()
            res.send()
    }
    catch(error)
    {
         res.status(400).send(error);
 
    }
 });

module.exports = router;

Create Model

StudentModel.js

const mongoose = require("mongoose")
const bcrypt = require( 'bcrypt' );

const jwt = require("jsonwebtoken")


var Schema  = mongoose.Schema;


var studentSchema = new Schema(
    {
        name: {
                type:String,
                required: true
        },
        address: {
            type:String,
            required: true
        },
        phone: {
            type:Number,
            required: true
        }
   
    }
)

module.exports = mongoose.model('student',studentSchema);

Angular

Angular is a front-end application we have already created the folder front end inside the folder open the command prompt and type the commands.

Installing Angular CLI

npm install -g @angular/cli

ng new frond-end

Select the SCSS Style for the Advanced CSS and Press Enter Key.

After complete the installation then run the project using following command.

ng serve

Now you see the Angular Welcome Page.

After that open the Angular project into VS code editor.

now you can see the following file structure

Creating a new Component student type by following command

ng g c student

After that Add the  Bootstrap Styles.go to the bootstrap official website and copy the CSS style then paste the style in to index.html file inside the <head> 

<head>
  <meta charset="utf-8">
  <title>FrontendProject</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">

  <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-9ndCyUaIbzAi2FUVXJi0CjmCapSmO7SnpJef0486qhLnuZ2cdeRhO02iuK6FUUVM" crossorigin="anonymous">

</head>

app.module.ts

FormModule
HttpClientModule

add these module into the app.module.ts file  then only we will manage the forms and Http requests.

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { StudentcrudComponent } from './studentcrud/studentcrud.component';
import { HttpClientModule } from '@angular/common/http';
@NgModule({
  declarations: [
    AppComponent,
    StudentcrudComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    FormsModule,
    HttpClientModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

After that open up the student.component.html

student.component.html

<div class="container mt-4" >
  <div class="card">
          <h1>Student Registation</h1>
<form>
  <div class="form-group">
    <label>Name</label>

      <input type="text" class="form-control" [(ngModel)]="phone" [ngModelOptions]="{standalone: true}" id="phone" placeholder="Enter Phone"> 
    </div>
  <button type="submit" (click)="save()" class="btn btn-primary">Submit</button>
</form>

</div>
<div class="container mt-4" >

  </tr>

<tbody>
    <tr *ngFor="let StudentItem of StudentArray">
    <td>{{StudentItem.name  | uppercase}}</td>
    <td>{{StudentItem.address }}</td>
    <td>{{StudentItem.phone }}</td>
    <td>
      <button type="button" class="btn btn-success" (click)="setUpdate(StudentItem)">Edit</button>
      <button type="button" class="btn btn-danger" (click)="setDelete(StudentItem)">Delete</button>            
    </td>
  </tr>

</table>
