Express.js Tutorial: Generate PDF File Degnan Data Dinamis

Express.js is a popular web application framework for Node.js that makes it easy to build web applications and APIs. In this tutorial, we will learn how to generate a PDF file from dynamic data using Express.js.

Setup

Before we start, make sure you have Node.js and npm installed on your machine. You can install Express.js by running the following command:

npm install express

Generate PDF File

To generate a PDF file from dynamic data in Express.js, we can use a library like pdfkit. First, install the library by running the following command:

npm install pdfkit

Once the library is installed, we can use it to create a PDF file with dynamic data. Here’s an example of how to generate a simple PDF file in Express.js:

const express = require('express');
const PDFDocument = require('pdfkit');
const fs = require('fs');

const app = express();

app.get('/generate-pdf', (req, res) => {
  const doc = new PDFDocument();
  doc.pipe(fs.createWriteStream('output.pdf'));

  doc.text('Hello, this is a PDF file generated from Express.js.');

  doc.end();
  res.send('PDF file generated successfully!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
  

In this example, we create a new PDF document using PDFDocument from the pdfkit library. We then pipe the document to a file using fs.createWriteStream and write some text to the document using doc.text.

Conclusion

Generating a PDF file from dynamic data in Express.js is straightforward with the help of libraries like pdfkit. In this tutorial, we learned how to install pdfkit and generate a simple PDF file in Express.js.
