nodejs, jsPDF and Windows

Question

I am unable to install jsPDF in my nodejs with npm. I have npm install node-jspdf to work with nodejs, but does not install because it gives problem when running the file install.sh. Even specifying the version of the package gives problem. So I downloaded the zip from Node-jspdf (indicated in the file install.sh), unzipped and created the necessary folders, indicated in the same installation file. When running the app the module is not located. However I was able to generate a PDF referencing the module directly, but I don’t know if it works for later:

HOW THE APP WORKED IN PRINCIPLE:

var fs = require('fs');
var path = './jsPDF/';
jsPDF = require(path + 'jspdf');

var doc = new jsPDF();
doc.text('Hello world!', 10, 10);
fs.writeFile('teste.pdf', doc.output());

The PDF is created correctly in the local folder. But I intend to have it sent to the browser. But if I use the example of Githud, as shown below, the error "Navigator is not defined":

SO THE APP GAVE ERROR

var fs = require('fs');
var path = './jsPDF/';
jsPDF = require(path + 'jspdf');

var doc = new jsPDF();
doc.text('Hello world!', 10, 10);

doc.save('Test.pdf', function(err){console.log('saved!');});  // <<<<<<==== Gera o erro

Questions: 1) Can I use jspdf indicating the module path directly and saving the file the way it worked? 2) Wouldn’t this "Navigator is not defined" error be because I’m just running a script? I guess running via browser will stop the problem...

Answer 1

According to the documentation, the jsPDF is a package client-side. How are you working with node, then the package they recommend is the node-jspdf. For this I recommend uninstalling your jspdf and install node-jspdf through:

npm unistall jspdf --save
npm install node-jspdf --save

I hope it works now, hugs!

Answer 2

For registration only: I was able to run the PDF generation, but not via normal installation with npm install. I did the following: 1) I downloaded the jsPDF master ZIP file on Github, in the Releases the version compatible with my version of Nodejs, because I am not using the most current one (the reason is not the case); 2) I unzipped the file and put it right in the folder node_modules of my project; 3) In the code I pointed the package directly in the relative path: require('./meu_path_relativo/node_modules/pasta_jsPDF/jspdf');

I know it’s not the right strategy, but it was the only way to make it work on my Windows installation.
