Down and dirty PDF rendering in Node.js
npm install nodepdf
- PhantomJS
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
});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.
{
'viewportSize': {
'width': 2880,
'height': 1440
},
'paperSize': {
'format': 'A4',
'orientation': 'portrait',
'margin': {
'top': '1cm',
'right': '1cm',
'bottom': '1cm',
'left': '1cm'
}
},
'outputQuality': '80', //set embedded image quality 0 - 100
'zoomFactor': 1,
'args': '',
'captureDelay': 400
}You can set all the properties from here: http://phantomjs.org/api/webpage/
var NodePDF = require('nodepdf');
var pdf = new Pdf('http://yahoo.com', 'yahoo.pdf', {
'cookies': [
{
'name': 'Valid-Cookie-Name 1', /* required property */
'value': 'Valid-Cookie-Value 1', /* required property */
'domain': 'localhost', /* required property */
'path': '/foo',
'httponly': true,
'secure': false,
'expires': (new Date()).getTime() + (1000 * 60 * 60) /* <-- expires in 1 hour */
},
{
'name': 'Valid-Cookie-Name 2',
'value': 'Valid-Cookie-Value 2',
'domain': 'localhost'
}
]
