Meteor: Dynamic pdf generation with pdfKit and FlowRouter - meteor

Question

I'm using pdfKit and FlowRouter on my meteor App. I would like to generate a pdf file without saving it an the server. In the docs there is an example for that:
Router.route('/getPDF', function() {
var doc = new PDFDocument({size: 'A4', margin: 50});
doc.fontSize(12);
doc.text('PDFKit is simple', 10, 30, {align: 'center', width: 200});
this.response.writeHead(200, {
'Content-type': 'application/pdf',
'Content-Disposition': "attachment; filename=test.pdf"
});
this.response.end( doc.outputSync() );
}, {where: 'server'});
But this is for Iron Router usage. As I'm using FlowRouter, I don't know how to display/download the pdf directly to the user without saving the file on the server.

Answer 1

Use the server side router from meteorhacks picker. Then something along the lines of
Picker.route('/generate/getPdf', function(params, req, res, next) {
var doc = new PDFDocument({size: 'A4', margin: 50});
doc.fontSize(12);
doc.text('PDFKit is simple', 10, 30, {align: 'center', width: 200});
res.writeHead(200, {
'Content-Type': 'application/pdf',
'Content-Disposition': 'attachment; filename=test.pdf'
});
res.end(doc.outputSync());
});
UPDATE: now that outputSync is deprecated, use:
Picker.route('/generate/getPdf', function(params, req, res, next) {
var doc = new PDFDocument({size: 'A4', margin: 50});
doc.fontSize(12);
doc.text('PDFKit is simple', 10, 30, {align: 'center', width: 200});
res.writeHead(200, {
'Content-Type': 'application/pdf',
'Content-Disposition': 'attachment; filename=test.pdf'
});
doc.pipe(res);
doc.end();
});

Answer 2

Here's how to do it now that outputSync() has been removed:
Picker.route('/generate/getPdf', function(params, req, res, next) {
var doc = new PDFDocument({size: 'A4', margin: 50});
doc.fontSize(12);
doc.text('PDFKit is simple', 10, 30, {align: 'center', width: 200});
res.writeHead(200, {
'Content-Type': 'application/pdf',
'Content-Disposition': 'attachment; filename=test.pdf'
});
doc.pipe(res);
doc.end(res);
});
