var total = voters.find() meteor.methods({'generate_pdf': function() { console.log("--------inside pdf generation module----------"); var fs = npm.require('fs'), future = npm.require('fibers/future'), fut = new future(), filename = "report.pdf", voters = total, data = { voters: voters } ssr.compiletemplate('layout', assets.gettext('layout.html')); ssr.compiletemplate('report', assets.gettext('report.html')); var html_string = ssr.render('layout', { template: "report", data: data }); var options = { "papersize": { "format": "letter", "orientation": "portrait", "margin": "1cm" }, sitetype: 'html' }; console.log("------------commencing webshot-----------"); webshot(html_string, filename, options, function(err) { fs.readfile(filename, function (err, data) { if (err) { return console.log(err); } fs.unlinksync(filename); fut.return(data); }); }); console.log("------------waiting till pdf generated-----------"); let pdfdata = fut.wait(); let base64string = new buffer(pdfdata).tostring('base64'); console.log("------------return result-----------"); return base64string; } }); triggerpoint button : home.html
<template name="home"> <div class="container"> <div class="row"> <div class="col-sm-6 col-sm-offset-3"> <a href="#" class="generate-pdf">generate pdf</a> </div> </div> </div> </template> home.js
template.home.events({ 'click .generate-pdf': function(e, tmpl) { e.preventdefault(); meteor.call('generate_pdf', function(err, res) { if (err) { console.error(err); } else if (res) { window.open("data:application/pdf;base64, " + res); } }) } }); error log on console :

- while not able read file might not generated. can me out this, if case solved many in benefit ready boiler plate code here.
initially had below meteor packages create pdf using phantomjs , display on seperate tab: [for meteor version 1.3.2.4]
1. dfischer:phantomjs
2. meteorhacks:ssr
3. jaredmartin:future
4. meteorhacks:npm
5. bryanmorgan:webshot
after hours of debugging, found out had remove package bryanmorgan:webshot , manually add package entry "webshot":"0.15.4" in project/packages.json file. in short, had add npm's webshot meteor project.
then, had restart meteor , worked.
