This page summarizes the action plan for the Kiwix Google Zürich Hackathon 2018.



In Kiwix-js:

  • Stabilize and optimize the ServiceWorker mode, to try to make it the default mode (on platforms that support it). This mode should be much more sustainable in the long term.
  • Improve performance by using WebAssembly (on platforms that support it) for the bzip2 decompression. Preliminary tests let us hope around 30% performance improvement.
  • Investigate on compiling the libzim to WebAssembly. If it's technically possible, it would allow to benefit from all the features and optimizations of this library, without the need of re-implementing them. If the people from Google know this technology, it might be a topic where they would be helpful.


In Kiwix-Android:

  • Work on 3.0
  • Download improvements (improve stability)
  • Search Improvements / Discussions


In Kiwix-Android:

  • Implement test code coverage report in Travis see
  • Help to reduce the number of crashes occurring for our users. Isaac agree the download manager code is the epicentre of many of the problems and he's planning to revise it during the hackathon. I'm happy to help with testing the changes.



  • Release Kiwix-plug installer 2.0
