NodePDF
Down and dirty PDF rendering in Node.js
Installation
npm install nodepdf
Dependencies
- PhantomJS
Contsructor API
You can use NodePDF two ways, one is using a contstructor that returns an instance of EventEmitter.
var NodePDF = require('nodepdf');
// last argument is optional, sets the width and height for the viewport to render the pdf from. (see additional options)
var pdf = new NodePDF('http://www.google.com', 'google.pdf', {
'viewportSize': {
'width': 1440,
'height': 900
},
'args': '--debug=true'
});
pdf.on('error', function(msg){
console.log(msg);
});
pdf.on('done', function(pathToFile){
console.log(pathToFile);
});
// listen for stdout from phantomjs
pdf.on('stdout', function(stdout){
// handle
});
// listen for stderr from phantomjs
pdf.on('stderr', function(stderr){
// handle
});Or set the content directly instead of using a URL:
var pdf = new NodePDF(null, 'google.pdf', {
'content': '<html><body><img src="https://www.google.com/images/srpr/logo11w.png" alt="google"/></body></html>',
'viewportSize': {
'width': 1440,
'height': 900
},
});You can set the header and footer contents as well:
var NodePDF = require('nodepdf');
var pdf = new NodePDF('http://yahoo.com', 'yahoo.pdf', {
'viewportSize': {
'width': 3000,
'height': 9000
},
'paperSize': {
'pageFormat': 'A4',
'margin': {
'top': '2cm'
},
'header': {
'height': '1cm',
'contents': 'HEADER {currentPage} / {pages}' // If you have 2 pages the result looks like this: HEADER 1 / 2
},
'footer': {
'height': '1cm',
'contents': 'FOOTER {currentPage} / {pages}'
}
},
'outputQuality': '80'
'zoomFactor': 1.1
});Callback API
The callback API follows node standard callback signatures using the render() method.
var NodePDF = require('nodepdf');
// options is optional, sets the width and height for the viewport to render the pdf from. (see additional options)
NodePDF.render('http://www.google.com', 'google.pdf', options, function(err, filePath){
// handle error and filepath
});
// use default options
NodePDF.render('http://www.google.com', 'google.pdf', function(err, filePath){
// handle error and filepath
});As soon the content option is set, the URL is ignored even if you set one.
