modfin/betterpress repository overview

⁠Betterpress

Betterpress wraps openhtmltopdf⁠ in a Spark server inside a docker container. This makes for a convenient pdf generation service over http.

⁠User Guide

1. Download/run the docker image:

   docker run -p 7357:8080 modfin/betterpress
   

   Copy

2. Send files over http as multipart form data where the index file/entry point must have name property index.html. This looks something like the following:

   POST /
   User-Agent: myagent
   Accept: */*
   Host: localhost:7357
   accept-encoding: gzip, deflate
   content-type: multipart/form-data; boundary=myboundary
   content-length: 192668
   
   --myboundary
   Content-Disposition: form-data; name="index.html"; filename="myindexfile.html"
   
   [index.html binary]
   --myboundary
   Content-Disposition: form-data; name="styles.css"; filename="styles.css"
   
   [styles.css binary]
   --myboundary
   Content-Disposition: form-data; name="font.ttf"; filename="font.ttf"
   
   [font.ttf binary]
   --myboundary--
   

   Copy

   ℹ️ tip - don't write this by hand, use a http library :)

3. Betterpress will reply with the generated pdf file

⁠Notes

Betterpress always uses W3CDom().fromJsoup(indexDoc) mentioned in the openhtmltopdf integration guide⁠. I.e. make sure to send index.html in html5 format. Note that css2.1 still is a limit so e.g. for fonts we must use @font-face instead of @import.
