Create an PDF Converter Website

Step 1: Project Setup

Tools/Technologies you will need:

  • Node.js (for the backend)
  • React.js (for the frontend)
  • Express.js (backend server framework)
  • MongoDB (for storing user data)
  • AWS S3/Google Cloud Storage (for file storage)
  • JWT (for user authentication)
  • Python (for file conversion scripts)

Step 2: Frontend (React.js)

  1. Create a React app: If you don’t have Node.js installed, you can download and install it from here. Then, create your React app using:
bash

npx create-react-app free-file-convert
cd free-file-convert
npm start

2. Basic File Upload UI: In your src/App.js, create a file upload and conversion UI.

jsx

import React, { useState } from 'react';

function App() {
  const [file, setFile] = useState(null);
  const [conversionType, setConversionType] = useState('pdf-to-word');
  
  const handleFileChange = (e) => {
    setFile(e.target.files[0]);
  };

  const handleConversion = async () => {
    const formData = new FormData();
    formData.append('file', file);
    formData.append('conversionType', conversionType);

    const response = await fetch('http://localhost:5000/convert', {
      method: 'POST',
      body: formData
    });

    if (response.ok) {
      const blob = await response.blob();
      const url = URL.createObjectURL(blob);
      window.location.href = url; // To download the converted file
    }
  };

  return (
    

      
      
    

  );
}

export default App;

Step 3: Backend (Node.js + Express.js)

  1. Create the Node.js backend:
    • First, initialize the project:
bash

mkdir backend
cd backend
npm init -y
npm install express multer body-parser
  • Create the backend structure:
bash

backend/
├── controllers/
├── models/
├── routes/
├── services/
└── server.js

2. Set up file upload with Multer (file handling):

Install Multer to handle file uploads:

bash

npm install multer

Inside server.js:

javascript


const express = require('express');
const multer = require('multer');
const path = require('path');
const { convertFile } = require('./services/fileConversion');

const app = express();
const upload = multer({ dest: 'uploads/' });

app.post('/convert', upload.single('file'), async (req, res) => {
  const { file, body } = req;
  if (!file) {
    return res.status(400).send('No file uploaded');
  }

  try {
    const convertedFilePath = await convertFile(file.path, body.conversionType);
    res.download(convertedFilePath, 'converted-file.pdf');
  } catch (error) {
    res.status(500).send('Error converting file');
  }
});

app.listen(5000, () => console.log('Server is running on port 5000'));

3. File Conversion Logic: Inside services/fileConversion.js, write a basic function to handle file conversion. For simplicity, let’s convert PDFs to images:

javascript


const { exec } = require('child_process');
const path = require('path');

function convertFile(inputFilePath, conversionType) {
  return new Promise((resolve, reject) => {
    const outputFilePath = path.join('output', 'converted-file.jpg'); // Example for PDF to JPG

    exec(`pdftoppm ${inputFilePath} ${outputFilePath} -jpeg`, (err, stdout, stderr) => {
      if (err) {
        reject('Conversion failed');
      }
      resolve(outputFilePath);
    });
  });
}

module.exports = { convertFile };

Step 4: File Storage (AWS S3 or Google Cloud Storage)

  1. Integrate file storage (AWS S3 or Google Cloud) for uploading and saving converted files.
    • Install AWS SDK (for S3):
bash


npm install aws-sdk
  • Set up AWS credentials in your .env file:
ini


AWS_ACCESS_KEY_ID=your-access-key
AWS_SECRET_ACCESS_KEY=your-secret-key
AWS_REGION=your-region
S3_BUCKET_NAME=your-bucket-name
  • Example of uploading a file to S3:
javascript


const AWS = require('aws-sdk');
const s3 = new AWS.S3();

function uploadFileToS3(filePath) {
  const params = {
    Bucket: process.env.S3_BUCKET_NAME,
    Key: path.basename(filePath),
    Body: fs.createReadStream(filePath),
  };

  return s3.upload(params).promise();
}

2. Cloud storage integration allows users to save and fetch files from cloud services like Google Drive or Dropbox.

Step 5: User Authentication (JWT)

  1. Install JWT and bcrypt:
bash


npm install jsonwebtoken bcryptjs
  1. JWT Authentication Example:
javascript


const jwt = require('jsonwebtoken');
const bcrypt = require('bcryptjs');

function generateToken(user) {
  return jwt.sign({ id: user.id }, 'your-secret-key', { expiresIn: '1h' });
}

// Signup example:
function signUp(req, res) {
  const { username, password } = req.body;
  const hashedPassword = bcrypt.hashSync(password, 10);
  // Save user to the database (MongoDB or SQL)
  const newUser = { username, password: hashedPassword };
  const token = generateToken(newUser);
  res.json({ token });
}

Step 6: Frontend Integration

  • Link the frontend (React) with the backend (Node.js):
    • In your React app, use fetch or Axios to make HTTP requests to the backend.
    • Display the converted files or error messages on the frontend.

Step 7: Deployment

  1. Frontend Deployment:
    • Use platforms like Netlify or Vercel for hosting the React app.
  2. Backend Deployment:
    • Deploy the backend using Heroku, AWS EC2, or DigitalOcean.
  3. Database:
    • Use MongoDB Atlas or AWS RDS for storing user data.
