EXPRESS JS TUORIAL | UPLOAD EXCEL DATA KE DATABASE

Welcome to our tutorial on how to upload excel data to a database using Express JS. Express is a popular web application framework for Node.js that provides a robust set of features for building web applications and APIs. In this tutorial, we will guide you through the process of creating an Express JS application that allows users to upload excel data and store it in a database.

Setting up the Environment

Before we begin, make sure you have Node.js and npm installed on your computer. You can download and install them from the official website if you haven’t already done so. Once you have Node.js and npm installed, create a new directory for your project and navigate to it in your terminal or command prompt. Run the following command to initialize a new Node.js project:


npm init -y


This will create a new package.json file in your project directory. Next, install Express and other required dependencies by running the following command:


npm install express multer mysql exceljs --save


Creating the Express Application

Now that we have set up the environment, let’s create our Express application. Create a new file called app.js in your project directory, and add the following code to it:


const express = require('express');
const multer = require('multer');
const mysql = require('mysql');
const ExcelJS = require('exceljs');
const app = express();

// Add code for handling file uploads and database storage here


Handling File Uploads and Database Storage

Now we will add the code for handling file uploads and storing the excel data in a database. We will use the multer middleware to handle file uploads and the mysql package to interact with the database. The ExcelJS package will be used to read the uploaded excel file and extract the data from it. Here is an example of how to handle file uploads and database storage in Express:
