nodejs stream finish callback after pipe is not launched
If pdf is a proper NodeJS stream, you can simply pipe it into the write stream and be done. If you want to quit your program after the file is saved, you could do this on 'close'.Notice: there is no "after saving" state (because you end the process). That console.log("After save") line in your code is called before the file is saved!
docx2pdf(doc, function (pdf) { console.log("saving file"); var pdfFile = fs.createWriteStream("./test2.pdf"); pdf.pipe(pdfFile); pdfFile.on('close',function(){ console.log("Finished"); process.exit(); });}, true, true);
