NodeJS and PDFkit: 'margin' property gives "Unexpected identifier" error?

Question

I have successfully gotten my code to output a pdf, but when I attempt to adjust the margins using the 'margin' property listed in the documentation using the following code,

var pdf = require ('pdfkit');
var fs = require('fs');

var doc = new pdf(
{
    size: [288,144]

}
);

doc.pipe(fs.createWriteStream('run.pdf'));

doc.font('Times-Roman')
   .text('Hello different Times Roman!')

doc.addPage({
    size: [288,144]
    margin : 10
});

doc.end();

I get this error:

margin : 10
^^^^^^

SyntaxError: Unexpected identifier

    at Function.Module.runMain (module.js:441:10)
    at startup (node.js:139:18)

Am I missing something obvious here?

It's JSON, just include a comma after `size: [288,144]`. – Dandy Oct 27 '16 at 04:21 — Dandy, Oct 27 '16 at 04:21

Just to ensure any future reader come here with this specific problem, this is a JavaScript Object. When listing JavaScript Objects, every property must be followed by a , except the last instance.

As an example, this:

doc.addPage({
    size: [288,144]
    margin : 10
});

becomes this:

doc.addPage({
    size: [288,144], 
    margin : 10
});

This is a little pedantic, but it's not JSON, it's a JavaScript Object. It would be JSON if it were encoded as a string (http://stackoverflow.com/questions/8294088/javascript-object-vs-json). But the same formatting and syntax applies, so the problem was still solved. +1 – caffeinated.tech Oct 27 '16 at 09:50
