What is the procedure to change a docx file to PDF using "docxjs" in Angular 15?

edit

To convert a docx file to PDF using "docxjs" in Angular 15, you can follow these steps:

1. Install docxjs library: Use npm to install "docxjs" package by running the following command in your Angular project directory:

   npm install docxjs --save
   

2. Import docxjs library: In the component where you want to perform the conversion, import the "Docx" class from the "docxjs" library.

   import { Docx } from 'docxjs';
   

3. Load the docx file: Use the Docx class to load the docx file using its "load" method. This method returns a promise that resolves with the loaded document object.

   const doc = new Docx();
   doc.load('path/to/document.docx').then(document => {
      // Conversion logic goes here
   });
   

4. Convert the docx to PDF: To convert the loaded document to PDF format, call the "toBufferPDF" method on the document object. This method returns a promise that resolves with the converted PDF buffer.

   const pdfBufferPromise = document.toBufferPDF();
   pdfBufferPromise.then(pdfBuffer => {
      // Save or display the PDF buffer as per your requirement
   });
   

5. Handle errors: Handle any errors that may occur during the loading or conversion process.

   pdfBufferPromise.catch(error => {
      console.error('Error while converting to PDF:', error);
   });
   

Note: Make sure to update the path to the docx file in step 3 to match the location of your actual file. Also, you may need to install additional dependencies (such as "jszip") for "docxjs" to function properly.
