Create PDF from HTML Template Using IronPDF for Node.js

IronPDF for Node.js offers a feature that allows users to create PDFs from either an HTML template or an HTML page. This functionality enables users to populate these templates with inputs provided by the user.

The code provided below will demonstrate how to generate and write a PDF document using an HTML template.

import { PdfDocument } from "@ironsoftware/ironpdf";
import readline from 'readline';

// Function to generate a PDF document based on user input and an HTML template
const generatePdf = async (userInput, fileName) => {
  // HTML template with placeholders for dynamic content
  const htmlTemplate = `
<!DOCTYPE html>
  <html>
  <body>
    <h1>${userInput.title}</h1>
    <p>User's name: ${userInput.userName}</p>
    <p>User's email: ${userInput.userEmail}</p>
  </body>
  </html>
`;

  // Create a PDF from the modified HTML template
  const pdf = await PdfDocument.fromHtml(htmlTemplate);

  // Save the PDF document under the specified file name
  await pdf.saveAs(fileName);
  console.log(`PDF saved as ${fileName}`);
};

// Create an interface for reading data from the terminal
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

// Collect user input for the PDF document
rl.question('Enter title: ', (title) => {
  rl.question('Enter user name: ', (userName) => {
    rl.question('Enter user email: ', async (userEmail) => {
      // Store user-provided data in an object
      const userInput = {
        title,
        userName,
        userEmail
      };

      // Generate the PDF using the user input
      await generatePdf(userInput, "output.pdf");

      // Close the readline interface
      rl.close();
    });
  });
});
import { PdfDocument } from "@ironsoftware/ironpdf";
import readline from 'readline';

// Function to generate a PDF document based on user input and an HTML template
const generatePdf = async (userInput, fileName) => {
  // HTML template with placeholders for dynamic content
  const htmlTemplate = `
<!DOCTYPE html>
  <html>
  <body>
    <h1>${userInput.title}</h1>
    <p>User's name: ${userInput.userName}</p>
    <p>User's email: ${userInput.userEmail}</p>
  </body>
  </html>
`;

  // Create a PDF from the modified HTML template
  const pdf = await PdfDocument.fromHtml(htmlTemplate);

  // Save the PDF document under the specified file name
  await pdf.saveAs(fileName);
  console.log(`PDF saved as ${fileName}`);
};

// Create an interface for reading data from the terminal
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

// Collect user input for the PDF document
rl.question('Enter title: ', (title) => {
  rl.question('Enter user name: ', (userName) => {
    rl.question('Enter user email: ', async (userEmail) => {
      // Store user-provided data in an object
      const userInput = {
        title,
        userName,
        userEmail
      };

      // Generate the PDF using the user input
      await generatePdf(userInput, "output.pdf");

      // Close the readline interface
      rl.close();
    });
  });
});
JAVASCRIPT

The above code example defines a JavaScript program that takes user input for a title, user name, and user email through the command line using the readline module. The generatePdf() method is defined to create a PDF document using a provided HTML template and save it with the given file name. The HTML template includes placeholders for the title, user name, and user email, which are filled in with the user-provided data. The PdfDocument class from the @ironsoftware/ironpdf package is used to create the PDF from the HTML template. After generating the PDF, it is saved with the specified file name and a message confirming the save is logged to the console.

The readline module is used to prompt the user for relevant data as input, asking for the title, username, and user email in a sequence of questions. The user's responses to these prompts are collected and stored in an object called userInput. The generatePdf() method is then called with this user input and a default file name "output.pdf" to create and save or download the PDF document based on the provided data. Finally, the readline interface is closed, ending the program.
