I don't quite understand and it's on me, trust me :)

My reading is you were worried about length of encoding one state, so you moved to encapsulating states in a dictionary with keys of hash of State and objects of State

And this led to a decrease in size of the URL?

My guess at my misunderstanding: you kept the state dictionary server-side or at least some other storage method than the URL, and just used the URL to identify which state to use from the dictionary. I e. The bit you add to the URL is just the hash of the state, or dictionary key

Yes, in the final solution we just stored a hash sum inside the URL fragment (I think it was an MD5 sum) and the actual state inside a JS object in main memory. With a page reload you lost all states which was fine for us but you could use session storage to avoid that.
