javascript - jsPDF server side (node.js) usage using node-jspdf

Question

I am actually trying to include jspdf in server side and then use it for simple pdf generation(simply the text "Hello world!")(Go to the url- get the pdf localhost:8080). Now the first problem I face is

• How to include it / What to do to use jsPDF in node?
• While trying to install it using npm install node-jspdf then it gives following error-

 node-jspdf@0.0.3 install G:estmyproj
ode_modules
ode-jspdf
 sh install.sh

Can anybody help me on how to include it in node? And give a 4-5 line demo.

You can actually use jspdf directly (npm install jspdf instead of npm install node-jspdf). Jspdf is currently (v1.3.2) not built with node support in mind, but you can mock the globals like below and get it to work that way. This is a basic example and all features of jspdf will not be available.

global.window = {document: {createElementNS: () => {return {}} }};
global.navigator = {};
global.html2pdf = {};
global.btoa = () => {};

var fs = require('fs');
var jsPDF = require('jspdf');

var doc = new jsPDF();
doc.text("Hello", 10, 10);
var data = doc.output();

fs.writeFileSync('./document.pdf', data, 'binary');

delete global.window;
delete global.html2pdf;
delete global.navigator;
delete global.btoa;
