wkhtmltopdf-flask-aas's Issues

Render react.js pages

Current result: blank or black pages instead expected content. May be need wait few seconds (for page loading and script execution) before rendering?

Make the port configurable by config file, defaults to 80

Unicode encode error

I got the following UnicodeEncodeError:

[2017-03-10 13:21:05,861] ERROR in app: Exception on /pdf [POST]
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1988, in wsgi_app

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: ordinal not in range(128)

This is how I did the request:

response = requests.post(
    'http://localhost:5000/pdf', data={
    'html': 'áááááá',
    'options': {'encoding': 'UTF-8'},
})

Any advices?

Filter health checks in log

When you configure health checks in docker/kubernetes/whatever the log gets "spammed" with these requests.
It would be neat to filter that from the requestlogging.

I don't know the stack, so I have no clue where to start.
I was able to add a simple health endpoint by adding

@app.route("/health", methods=['GET'])
def health():
return Response("{healthy: 'true'}", mimetype='application/json')

to the app.py, but I don't know where to skip the access-log for the endpoint.

BTY: a health endpoint is a good idea, even docker itself supports that now

pages

Hi! I love your work. I am trying to make page numbers alternately appear at the bottom left for odd pages and bottom right for even pages. Is there a way to do that?
What I have so far is this...

wkhtmltopdf_path = 'C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=wkhtmltopdf_path)
options = {
    'footer-center': '~ [page] of [topage] ~',

Add testing using travis-ci

We should provide some testing using travis-ci

Reduce docker image size

The current size is 830MB, it should be smaller

Adding logs to console for successful calls and errors as well

Add logs to flask in order to know what is happening when the microservice is in production server.

'unicode' is not defined with alpine

I got the following error when generating a PDF from HTML with the "alpine" tag:

I tried with the docker image with "latest" tag based on Debian, it works as expected.

How can I update the dockerfile or app.py to make it works also on alpine?

It's time to upgrade docker image
