Load document from stream Leave feedback

There might be a case when your file is not physically located on the disk. Instead, you have the file in the form of a stream. In this case, to avoid the overhead of saving the stream as a file on disk, GroupDocs.Conversion enables you to convert the file streams directly.

To load a file from a stream, follow these steps:

1. Specify the method to obtain the file stream.
2. Pass the method’s name to the Converter class constructor.

The following code snippet serves this purpose:

const fs = require('fs')
const outputPath = "LoadDocumentFromStream.pdf"

try {
  const readStream = fs.createReadStream("sample.docx")
  const stream = await groupdocs.conversion.readDataFromStream(readStream)
  const converter = new groupdocs.conversion.Converter(stream);
  const convertOptions = new groupdocs.conversion.PdfConvertOptions()

  console.log(`Source document converted successfully to ${outputPath}`)
  return converter.convert(outputPath, convertOptions)

} catch (error) {
  throw new Error(error)
}

The snippet above uses the createReadStream method. Similarly, you can use any other type of stream. Just make sure that the source stream contains any of the supported file formats.
