Download PDF Files from URL Using IronPDF for Node.js
IronPDF for Node.js provides a powerful feature allowing the rendering of PDFs directly from URLs and subsequently saving them in the local file system. Essentially, it operates as a comprehensive PDF downloader, offering the capabilities of a full-version PDF downloader.
The following code can create and save PDF files from a URL using IronPDF for Node.js.
import { PdfDocument } from "@ironsoftware/ironpdf";
// Asynchronously render and save a PDF from a URL
(async () => {
try {
// Define the URL of the web page to be rendered as a PDF
const url = "https://ironpdf.com/";
// Render the web URL to a PDF document
const pdf = await PdfDocument.fromUrl(url);
// Save the PDF document to a file
await pdf.saveAs("pdf-from-url.pdf");
console.log("PDF successfully downloaded and saved as 'pdf-from-url.pdf'");
} catch (error) {
console.error("An error occurred while downloading the PDF:", error);
}
})();
import { PdfDocument } from "@ironsoftware/ironpdf";
// Asynchronously render and save a PDF from a URL
(async () => {
try {
// Define the URL of the web page to be rendered as a PDF
const url = "https://ironpdf.com/";
// Render the web URL to a PDF document
const pdf = await PdfDocument.fromUrl(url);
// Save the PDF document to a file
await pdf.saveAs("pdf-from-url.pdf");
console.log("PDF successfully downloaded and saved as 'pdf-from-url.pdf'");
} catch (error) {
console.error("An error occurred while downloading the PDF:", error);
}
})();
The provided code is a JavaScript program that utilizes the IronPDF for Node.js library to generate a PDF from a specified URL and save it as a PDF file. Let's break down the code step-by-step:
Importing the
PdfDocument
class from IronPDF:import { PdfDocument } from "@ironsoftware/ironpdf";
import { PdfDocument } from "@ironsoftware/ironpdf";
JAVASCRIPTThis line imports the
PdfDocument
class from the IronPDF library, which is used to work with PDF documents.Using an asynchronous
IIFE
(Immediately Invoked Function Expression):(async () => { /* Code here */ })();
(async () => { /* Code here */ })();
JAVASCRIPTThis structure defines an immediately invoked function expression that is marked as
async
, allowing the use ofawait
within the function. It invokes itself immediately after declaration.Rendering a web URL to PDF:
const pdf = await PdfDocument.fromUrl("https://ironpdf.com/");
const pdf = await PdfDocument.fromUrl("https://ironpdf.com/");
JAVASCRIPTThis line uses the
fromUrl
static method of thePdfDocument
class to render a web page URL (in this case, "https://ironpdf.com/") as a PDF document.Exporting the PDF document:
await pdf.saveAs("pdf-from-url.pdf");
await pdf.saveAs("pdf-from-url.pdf");
JAVASCRIPTThis line uses the
saveAs
method of the PDF document to save the generated PDF to a file named "pdf-from-url.pdf". Theawait
keyword is used to wait for the save operation to complete.
Overall, this script uses IronPDF to fetch a web URL, render it as a PDF document, and save the downloaded PDF file as a local file with the specified filename "pdf-from-url.pdf". The use of async/await
allows for handling the asynchronous nature of PDF generation and file saving.
