Javascript - PDF file creation using html-pdf

To create a PDF file using the html-pdf package in Node.js, you'll need to first install the package and then use it to convert HTML content into a PDF file. Here's a step-by-step guide:

  1. Install html-pdf: If you haven't already installed the html-pdf package, you can do so via npm:

    npm install html-pdf

  2. Create HTML Content: Create the HTML content that you want to convert into a PDF. This can be a simple HTML string or a file containing HTML content.

    <!-- index.html --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>PDF Example</title> </head> <body> <h1>Hello, PDF!</h1> <p>This is a sample PDF created using html-pdf package.</p> </body> </html>

  3. Create PDF Using html-pdf: In your Node.js script, use the html-pdf package to convert the HTML content into a PDF file.

    const pdf = require('html-pdf'); const fs = require('fs'); // Read HTML file const htmlContent = fs.readFileSync('index.html', 'utf8'); // Options for PDF creation const options = { format: 'Letter' }; // Convert HTML to PDF pdf.create(htmlContent, options).toFile('output.pdf', function(err, res) { if (err) return console.log(err); console.log('PDF created successfully:', res.filename); });

    This script reads the HTML content from the index.html file, converts it into a PDF using the specified options (format: 'Letter' specifies the page format), and saves the PDF as output.pdf.

  4. Run the Script: Run the Node.js script:

    node your_script.js

    After running the script, you should see a message indicating that the PDF was created successfully.

That's it! You've now created a PDF file using html-pdf in Node.js. Adjust the HTML content and options according to your requirements.
