Extract Text From PDF using PDF.js Library

There are many situations where you may need to extract text from a PDF document. One way to do this is by using the PDF.js library along with JavaScript. PDF.js is a popular open-source PDF viewer that also includes text extraction capabilities.

Here’s a small piece of code that demonstrates how to use PDF.js to extract text from a PDF document:

      
        
        
          const url = 'your_pdf_document.pdf';

          const loadPdf = async () => {
            const pdfData = await fetch(url).then(res => res.arrayBuffer());
            const loadingTask = pdfjsLib.getDocument({ data: pdfData });
            const pdf = await loadingTask.promise;
            const textContent = await pdf.getPage(1).getTextContent();
            textContent.items.forEach(item => {
              const text = item.str;
              console.log(text);
            });
          };
          loadPdf();
        
      
    

This code fetches the PDF document, loads it using PDF.js, and then uses the `getTextContent` method to extract the text from the first page of the PDF document. It then logs the extracted text to the console.

You can modify this code to meet your specific requirements. For example, you can extract text from all pages of the PDF document, or apply additional processing to the extracted text.

By using PDF.js and JavaScript, you can easily extract text from PDF documents and use it in your applications or processes. This can be useful in scenarios such as document parsing, content analysis, or search indexing.
