 npm i @ironsoftware/ironpdf

This command will download and install the IronPDF library, making it available for use in your project. To install the IronPDF engine that is required for using IronPDF Library, run the following command on the console:

npm install @ironsoftware/ironpdf-engine-windows-x64

4. HTML to PDF generation

Now that IronPDF is downloaded and installed, let's explore how to use it for HTML to PDF conversion. We'll walk through three common scenarios: converting a URL to PDF, converting an HTML string to PDF, and converting an HTML file to PDF.

4.1. Creating PDF files from URL using IronPDF

Converting a web page to a PDF is a frequent requirement, especially when dealing with dynamic content generated by a server. IronPDF makes this process simple. Here's a basic code example:

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

(async () => {
  // URL of the web page to convert to PDF
  const url = "https://google.com";

  // Create a PDF document from the specified URL
  const pdf = await PdfDocument.fromUrl(url);

  // Save the PDF to a file
  await pdf.saveAs("output_from_url.pdf");
})();

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

(async () => {
  // URL of the web page to convert to PDF
  const url = "https://google.com";

  // Create a PDF document from the specified URL
  const pdf = await PdfDocument.fromUrl(url);

  // Save the PDF to a file
  await pdf.saveAs("output_from_url.pdf");
})();

This code uses the IronPDF library to convert a web page (Wikipedia's PDF page) into a PDF file. It sets the page provided URL, helps generate PDF with PdfDocument.fromUrl() method, and saves it as "output_from_url.pdf". The entire process is wrapped in an asynchronous function, ensuring sequential execution. This snippet showcases the simplicity of leveraging IronPDF for HTML to PDF conversions in Node.js. For output refer to the below screenshot.

4.2. HTML String to PDF File

If you have HTML content as a string and need to convert it to a PDF, IronPDF provides a convenient method for this scenario as well:

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

(async () => {
    // Create a PDF from an HTML string
    const pdf = await PdfDocument.fromHtml("<h1>Hello Developers THis is an Example PDF created with IronPDF</h1>");

    // Export the PDF to a file
    await pdf.saveAs("output.pdf");
})();

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

(async () => {
    // Create a PDF from an HTML string
    const pdf = await PdfDocument.fromHtml("<h1>Hello Developers THis is an Example PDF created with IronPDF</h1>");

    // Export the PDF to a file
    await pdf.saveAs("output.pdf");
})();

This code example uses the IronPDF library to quickly convert a simple HTML string (a heading tag) into a PDF document. It then saves the generated PDF as "output.pdf." The script is concise, employing an asynchronous function for sequential execution. This showcases the simplicity of creating PDFs from HTML using IronPDF in a Node.js environment.

4.3. HTML File to PDF

For situations where the HTML content is stored in a file, IronPDF provides a straightforward method to convert it to a PDF. Here's an example:

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

(async () => {
    // Render the HTML file
    const pdf = await PdfDocument.fromHtml("label.html");

    // Export the PDF document
    await pdf.saveAs("output.pdf");
})();

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

(async () => {
    // Render the HTML file
    const pdf = await PdfDocument.fromHtml("label.html");

    // Export the PDF document
    await pdf.saveAs("output.pdf");
})();

This code snippet utilizes the IronPDF library to convert the content of an HTML file ("label.html") into a PDF document. The rendered PDF is then saved as "output.pdf." The simplicity of this process is highlighted by the concise script, which employs an asynchronous function for sequential execution in a Node.js environment.
