db.js

create db.js file to connect with the ms sql Server. Remember to to first authenticaiton at ms sql server, then you will get user and password.


const sql = require('mssql');

const config = {
  server: 'localhost',
  user: '',        // Your MS SQL Server username
  password: '',    // Your MS SQL Server password
  database: 'testing',  // Your database name
  pool: {
    max: 10,
    min: 0,
    idleTimeoutMillis: 30000,
  },
  options: {
    encrypt: true,
    trustServerCertificate: true,
    trustedConnection: true,
    connectionTimeout: 30000,
  },
};

const pool = new sql.ConnectionPool(config);

const connectToDatabase = async () => {
  try {
    await pool.connect();
    console.log('Connected to the database!');
    return pool;
  } catch (error) {
    console.error('Error connecting to the database:', error.message);
    throw error;
  }
};

module.exports = connectToDatabase;

app.js

creat app .js file first install the package


npm install @shamigondal/csv-uploader

Now write the following connectToDatabase


const express = require('express')
const path = require('path')
const bodyparser = require('body-parser')
const multer = require('multer')
const {uploadCsv} = require('csv-uploader')
const connectToDatabase = require('./db');



const app = express();

app.use(bodyparser.urlencoded({ extended: false }))
app.use(bodyparser.json())

const PORT = 4000 || 3000;
const localhost = `http://localhost:`

const storage = multer.diskStorage({

    destination: (req, file, callback) => {
        callback(null, './uploads')
    },
    filename: (req, file, callback) => {
        callback(null, file.fieldname + '-' + Date.now() + path.extname(file.originalname))
    }
})

const uploads = multer({
    storage: storage
})


app.get('/', (req, res) => {

    res.sendFile(__dirname + '/index.html')
})

app.post('/post-Csv-file', uploads.single('file'), async (req, res) => {
  try {
      console.log(req.file.path);
      const tableName = 'users'; // Replace with your table name
      const columnNames = ['userId', 'userName', 'userEmail', 'userPass']; // Replace with your column names
      await uploadCsv(path.join(__dirname, 'uploads', req.file.filename), tableName, columnNames, connectToDatabase);
      res.sendFile(__dirname + '/success.html');
  } catch (error) {
      console.error('Error processing CSV file:', error);
      res.status(500).send('Internal Server Error');
  }
});
  

app.listen(PORT, (req, res) => {

    console.log("CSV Faker listening at PORT " + localhost + PORT)
})
