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).

Answer 1

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;

Answer 2

In extension to the answer provided by Simon Bengtsson:

I managed to handle even latin-1 characters by sending the output of jsPdf to encoding:

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

var fs = require('fs');
var jsPDF = require('jspdf');
var encoding = require('encoding')
var doc = new jsPDF();
doc.text("HelloäöüßÄÖÜ©µ®", 10, 10);
var data = doc.output()
var buffer = encoding.convert(data, "Latin_1") 

fs.writeFileSync('./document.pdf', buffer);

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

Answer 3

I am able to install node-jspdf in Windows.

1. As suggested download jspdf-master.zip and extract it.

2. Now use the command:

   npm install <location on jspdf-master extract>
   

After that you can use npm list to see the installation success.

Answer 4

Download your jspdf folder from parallax jspdf. After installing jspdf ( "npm install jspdf" ) you get the jspdf folder inside node-modules. Go inside it and replace the jspdf.min.js by the jspdf.amd.min.js present in the /dist folder inside the jspdf downloaded from parallax

Answer 5

Node-jspdf mainly uses library jsPDF as the core library to render PDF file

but node-jspdf can only be installed on *unix system therefore you can download and install jsPDF manually by following steps in this file

I think you only need to install jsPDF to work with PDF file.
