How to minimize library size if I want to use only line charts functionality ?

[happytm]

I am running your excellent chart code on ESP32 micro controller but I do not need all features except simple line charts. Since it is running on micro controller with limited flash I would like to reduce size of javascript and css files.

Is it possible to make it barebones like around 20kb? If so how can I do it.

Thanks.

20kb might be tricky. it really depends on what features you need.

if you only need the line rendering, other renderers are easy to exclude. you can also exclude the points renderer and the uPlot.join() util func.

you can edit the feats.js file and run npm run build to make a custom build.

i wouldn't recommend excluding time or legend features, it will probably cause errors since those are more deeply integrated and i havent checked if all the necessary ifdefs are there currently.

i just tried it and this only saves about 7kb in total (50kb -> 43kb). looking through what remains, there are no obvious things that can be removed easily i'm afraid
