Getting Started with IronPDF for Node.js

1. Install Node.js: Download and install the latest version of Node.js from the official website.

2. Install the @ironpdf package: Use the terminal command below to install IronPDF using NPM:

   npm i @ironsoftware/ironpdf

3. Install the IronPDF Engine: Install the appropriate binary for your operating system:

   For Windows x64:

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

   For Windows x86:

   npm install @ironsoftware/ironpdf-engine-windows-x86

   For Linux x64:

   For macOS x64:

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

   For macOS/ARM:

   npm install @ironsoftware/ironpdf-engine-macos-arm64

   Tips

   IronPDF will attempt to download and install the correct binary for your system automatically when your Node.js project runs for the first time. However, in some cases, this action may be blocked by the machine. In such cases, you will need to install the binary using the commands provided above.

4. Apply a License Key (optional): In your Node.js project, set the IronPdfGlobalConfig.licenseKey property with a valid license key to use IronPDF:

   import {IronPdfGlobalConfig} from "@ironsoftware/ironpdf";
   
   (async () => {
       // Input the license key
       const IronPdfConfig = {
           licenseKey: "IRONPDF-MYLICENSE-KEY-1EF01",
       };
   
       // Set the config with the license key
       IronPdfGlobalConfig.setConfig(IronPdfConfig);
   })();

   import {IronPdfGlobalConfig} from "@ironsoftware/ironpdf";
   
   (async () => {
       // Input the license key
       const IronPdfConfig = {
           licenseKey: "IRONPDF-MYLICENSE-KEY-1EF01",
       };
   
       // Set the config with the license key
       IronPdfGlobalConfig.setConfig(IronPdfConfig);
   })();

   NODE.JS

   Please note

   A license key unlocks IronPDF's full collection of formatting and editing features and removes our tiled watermarks from your PDFs.

5. Enable Debug (optional): In your Node.js project, set the IronPdfGlobalConfig.debugMode property to true to enable debugging. This action will also create a log file in the current directory:

   import {IronPdfGlobalConfig} from "@ironsoftware/ironpdf";
   (async () => {
       var config = IronPdfGlobalConfig.getConfig();
       config.debugMode = true;
   })();

   import {IronPdfGlobalConfig} from "@ironsoftware/ironpdf";
   (async () => {
       var config = IronPdfGlobalConfig.getConfig();
       config.debugMode = true;
   })();

Using IronPDF for Node.js

Convert HTML to PDF

Use PdfDocument.fromHtml to convert raw HTML into PDFs. This method can work with a string containing HTML or a file path to an HTML document.

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

/* Convert an HTML String to a PDF */
const pdf_1 = PdfDocument.fromHtml("<h1>Hello world!</h1><p><small>A PDF brought to you by IronPDF for Node.js!</small></p>")
                         .then((pdf) => {
                            pdf.saveAs("./html-string-to-pdf.pdf");
                         });
await pdf_1;

/* Convert an HTML File to a PDF */
const pdf_2 = PdfDocument.fromHtml("./index.html")
                         .then((pdf) => {
                            pdf.saveAs("./html-file-to-pdf.pdf");
                         });
await pdf_2;

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

/* Convert an HTML String to a PDF */
const pdf_1 = PdfDocument.fromHtml("<h1>Hello world!</h1><p><small>A PDF brought to you by IronPDF for Node.js!</small></p>")
                         .then((pdf) => {
                            pdf.saveAs("./html-string-to-pdf.pdf");
                         });
await pdf_1;

/* Convert an HTML File to a PDF */
const pdf_2 = PdfDocument.fromHtml("./index.html")
                         .then((pdf) => {
                            pdf.saveAs("./html-file-to-pdf.pdf");
                         });
await pdf_2;

Convert URL to PDF

PdfDocument.fromUrl fetches a web page's content by URL and converts it into a PDF.

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

/* Convert an HTML String to a PDF */
const pdf = await PdfDocument.fromUrl("https://ironpdf.com/nodejs/");
await pdf.saveAs("./url_to_pdf.pdf");

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

/* Convert an HTML String to a PDF */
const pdf = await PdfDocument.fromUrl("https://ironpdf.com/nodejs/");
await pdf.saveAs("./url_to_pdf.pdf");
