Maybe switch to use slightlyoff/cassowary.js?!

Seems to be a replacement for the old version, claims to be very fast and future safe :) https://github.com/slightlyoff/cassowary.js

It's already been using cassowary.js, from the start

Sorry, i was confused due the npm version 0.0.2 and the git project has no tag or realese, which seems to be very old actually. Maybe use a more recent direct git repo reference as the grid style sheet does?

Last time I tried, I couldn't get the master build working, got all kinds of crazy and vague errors, so aborted on that. But if you're saying that it is working for others, then it might be worth investigating. Also, there is another version in the 'dist' folder. It uses the 'kiwi' constraint solver, which is waaaayy faster than cassowary.js. Benchmarks show about 8x performance improvement.

The kiwi impl used is this https://github.com/nucleic/kiwi/tree/feature-js?

Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. 

Sounds impressive, but last commit Apr 22, 2014

[IjzerenHein]

Yeah, the feature.js branch.

The 10x to 500x statement refers to the C++ version.

This is the current progress of the kiwi JS version: https://github.com/IjzerenHein/kiwi/tree/feature-js/ts

The original kiwi maintainer has yet to accept any pull requests, I think he's busy or has other priorities.

[mcbain]

So the kiwi dist uses your fork of kiwi?! 79 commit ahead :) .... Glad to know, that you were able to understand the code base.

[IjzerenHein]

Yeah, it uses my fork. The maintainer of the original kiwi TS version, never got around finishing it, so he asked whether I could help. I added a bunch tests, tooling, benchmarks, docs, and a higher level API for creating constraint expressions, and fixed some bugs..

[mcbain]

+100 :)
