Mac conversion not working

[gerhardcit]

macOS Sierra 10.12.3
node 6.9.1
phantomjs: 2.1.1

var app = express();

app.get('/', function (req, res) {
    var conversion = require("phantom-html-to-pdf")({
        timeout: 5000
    });

    conversion({ html: "<h1>Hello World</h1>" }, function (err, pdf) {
        if (err) {
            console.log(err);
            res.status(200).send(err);
        } else {
            console.log(pdf.logs);
            console.log(pdf.numberOfPages);
            pdf.stream.pipe(res);
        }
    });
});

result

{ Error: connect ECONNREFUSED 127.0.0.1:56033
    at Object.exports._errnoException (util.js:1026:11)
    at exports._exceptionWithHostPort (util.js:1049:20)

  errno: 'ECONNREFUSED',
  syscall: 'connect',

  port: 56033 }

And the port number keeps changing?
Any help on that please?

Can you try to use dedicated-process strategy?
https://github.com/pofider/phantom-html-to-pdf#global-options

Also, please try to find the phantomjs executable in node_modules and run it. Does it start?

[gerhardcit]

I also solved it by doing this
npm install phantomjs-prebuilt
and then

var conversion = require("phantom-html-to-pdf")({
        phantomPath: require("phantomjs-prebuilt").path, 
        timeout: 5000
    });

but if I deploy to Ubuntu will this still work?

[pofider]

It should.

@pofider
Running this on ubuntu 16.04
node 6.10.2

package.json contains

   "phantom-html-to-pdf": "^0.5.0",
   "phantomjs-prebuilt": "^2.1.14",

Init code

var conversion = require("phantom-html-to-pdf")({
    phantomPath: require("phantomjs-prebuilt").path
});

I'm using phantomPath because on mac that's the only way for it to work as mentioned above.

exec code

 conversion({
                html: htmlText,
                footer: '<div style="text-align:center">{#pageNum}/{#numPages}</div>',
                paperSize: {
                    format: 'A4',
                    orientation: 'portrait',
                    margin: '1cm'
                }
            }, function (err, pdf) {
                if (err) {
                   console.log(err)
                    cb(err);
                }
                else {
                    console.log(pdf.logs);
                    console.log(pdf.numberOfPages);
                    cb(null, pdf);
                }
            });

getting this error

$ phantomjs -v
produces this:

Fontconfig warning: ignoring UTF-8: not a valid region tag
1.9.8

Anything you can possible help me with?

[pofider]

Try to run this

apt-get install -y libfontconfig1 libfontconfig1-dev

We use this dockerfile to run this package on ubuntu https://github.com/jsreportonline/phantom-pdf/blob/master/Dockerfile
Just that it could help you to look inside.

[gerhardcit]

@pofider here is a basic test. That I cannot get running on a basic machine fresh after setup.
https://github.com/gerhardcit/phantom-html-to-pdf-test

Would one expect that to work on a fresh Ubuntu machine setup?
Is there something about phantomjs that I don't know about?

[gerhardcit]

@pofider, I tested that on a clean Ubuntu server.. just node and nginx.. perfect..
But not on the dev mac..
So what is compatibility with prebuilt about?

This pops up on mac with same node version

@pofider , signing this off.
I had experimented with html5-to-pdf which uses electron, and that did not go well.
So after all that, this is a config that works.

"dependencies": {
    "express": "^4.15.2",
    "phantom-html-to-pdf": "^0.5.0",
    "phantomjs-prebuilt": "^2.1.14"
  }

and

var conversion = require("phantom-html-to-pdf")({
    phantomPath: require("phantomjs-prebuilt").path
});

on Development Mac and on Ubuntu 16.04
