  function render(file) {         pdfjs.getdocument(file.path).then(function (pdf) {             pdfdoc = pdf;             totalpages = pdf.numpages;             renderpage(pagenumber)         }).catch(function (reason) {             console.error(reason);         });     }

and using worker 

pdfjs.workersrc = '//mozilla.github.io/pdf.js/build/pdf.worker.js';

the version of pdf.js using 1.7.225 lastest stable version.

use specific version of worker

pdfjs.workersrc = 'https://npmcdn.com/pdfjs-dist@1.7.225/build/pdf.worker.js';
