I am new to node.js and jsreport, but what I am attempting to do is create a pdf in memory using node.js and then saving it to disk. I need this to be stand-along as it will be running as an AWS Lambda function.

var fs = require('fs');
require("jsreport").render("<h1>Hi there!</h1>").then(function(out) {
    //pipe pdf with "Hi there!"
    fs.writeFile('C:\\helloworld.pdf', out, function (err) {
        if (err) return console.log(err);
        console.log('Hello World > helloworld.txt');
    });
fs.close();
    console.log("The End");
});

Although this runs the output pdf will not open in Adobe Reader so I assume the file output is not a valid PDF.

this requires npm install jsreport

From what I gather from the jsreport website (although I haven't been able to verify, as none of the examples on their website work for me), it looks like out isn't rendered (PDF) data, but an object that contains—amongst other things—a stream.

Which leads me to believe that this might work:

require("jsreport").render("<h1>Hi there!</h1>").then(function(out) {
  out.result.pipe(fs.createWriteStream('c:\\helloworld.pdf'));
});
