How to Read PDF Files in Node.js

In this tutorial, developers learn how to read PDFs using Node.js with the IronPDF Library. The process begins with installing the library using the command npm install iron-pdf and ensuring the binaries are installed. The tutorial walks through importing necessary modules such as PDFDocument and PDFGlobalConfig from the IronPDF library, which are crucial for accessing and manipulating PDF files.

Below is the corrected and well-documented example code:

// Import the necessary modules from the IronPDF library
const { PDFDocument, PDFGlobalConfig } = require('iron-pdf');

// Asynchronous function to create and process PDFs
async function createPDFs() {
  try {
    // Specify the path to the PDF file you want to open
    const pdfPath = 'label.pdf';

    // Load the PDF document
    const pdfDoc = await PDFDocument.fromFile(pdfPath);

    // Ensure the PDF is fully loaded and ready for manipulation
    await pdfDoc.init();

    // Extract text content from the PDF document
    const textContent = await pdfDoc.extractText();
    console.log('Extracted Text:', textContent);

    // Fetch the metadata of the PDF document
    const metadata = pdfDoc.getMetadata();
    console.log('PDF Metadata:', metadata);
  } catch (error) {
    // Handle any errors during the PDF processing
    console.error('Error processing the PDF:', error);
  }
}

// Execute the function to process the PDF
createPDFs();

Key Points:

1. Install IronPDF Library: Use the command npm install iron-pdf to add the IronPDF library to your Node.js project.

2. Import Modules: Import PDFDocument and PDFGlobalConfig from the IronPDF library, enabling PDF file manipulation and configuration.

3. Load PDF Document: Utilize the PDFDocument.fromFile() method to load the PDF. Ensure the document is initialized with pdfDoc.init().

4. Extract Text: Call pdfDoc.extractText() to retrieve all readable text from the PDF file.

5. Get Metadata: Use pdfDoc.getMetadata() to fetch essential information like author and creation date.

6. Error Handling: Implement error handling to manage any issues during the PDF processing.

The tutorial concludes by running the code to log the extracted text and metadata. This process highlights the potential of integrating PDF handling capabilities in Node.js applications, making it a valuable tool for developers.
