Picobrew Server Lines of Code Analysis

How much code went into building the chiefwigms/picobrew-pico server? If you don't know, now you know... Picobrew Server Edition

Picobrew Server Lines of Code Analysis

A bunch of people have now asked me how many lines of code did it take to build out the Picobrew server that we are using that is multi-platform and provides a fairly simple bundled image for bootstrapping people with a RaspberryPi (again the server isn't platform dependent feel free to get it setup on Win/Mac/Linux/etc).

So what did I do... well I programmatically measured out how many lines of code written in our shared community repo that was started by Pete Marinec (not me BTW!).

Server Code

The code that answers the API from both your web browser and from the Picobrew machines attached to the server.

Python Lines (including tests)

Python Lines (only tests...)

yeah test coverage sucks... yay side projects

Base Recipes (Zymatic only)

The Zymatic had a way for Picobrew to push some base utilities that later were bundled in the firmware for the ZSeries devices this is for Utilities > Cleaning v1, Utilities > Rinse v3, and Utilities > New Clean Beta v6 while connecting to the "mothership" can be edited remotely by Picobrew staff and sent updated to your device just like your recipe instructions... after all a clean or rinse is just a brew with no grains and no hops.

git ls-files | grep "\.json" | xargs wc -l
      90 app/recipes/zymatic/Cleaning_v1.json
     139 app/recipes/zymatic/New_Clean_Beta_v6.json

Static Code / Website

All the markup and javascript that powers the web experience you see at http://raspberrypi or http://picobrew.com or http://192.168.72.1 or http://<ip-of-flask/python-server> depending on your setup.

Javascript (dynamic code powering experience)

The majority of this code is libraries so I'll split that out separately like test coverage above. Though for now still including all of these libraries (which some have been minified meaning all lines are collapsed to a single set of them instead of "source" it won't do much...)

Binary (firmware...)

No this isn't code anyone from the community has written nor anyone really... this is compiled and packaged code that is shipped to your Picobrew devices via our server and thus included in the repository... wanted to include just for simple data collection (I personally love data even the "useless" kinds).

git ls-files | grep "\.bin" | xargs wc -l

Contribution Info and Statistics

The server as it exists today is largely built on top of another OSS project, hotzenklotz/picobrew-server, that had only support for Zymatic with no web UI or graph/visualization support. Pete took it from there as a prototype and a learning bed for new stuff (what us engineers like to do all the time). A few members from the community, myself included, have been working on adding additional features and fixes along the way. Now numbering 11 total people have contributed code where even more have been submitting feedback, bugs, and feature requests.

Can't quite comprehend what this means and want to see a video of it instead... well your wish is my command. Here is a fairly cool animation showing the actual server being built and maintained over time.

Additional thanks to the 34 additional people who have filed Github Issues some more detailed than others, but each are appreciated and glad you are finding value and helping to push for a better overall experience for everyone.

Much appreciated, Cheers 🍻!
