lacinia VS clj-tiles

Very specific example, but Lacinia, the primary GraphQL open source library used for Clojure apps, was developed by a guy at Walmart Labs. (He has since moved on though.)

https://github.com/walmartlabs/lacinia What I know about tech at Walmart is the Clojure lib above, which is the de facto graphql lib for the language today. Point being that tech existed for a while before big tech, and imo is going to be ever more present in more sectors of the economy. MAANG seems most relevant today in the capacities they gain from the amount of data they collect, and the importance of AWS for infrastructure (unless that's overrated, as it's starting to look like it is). What I know for sure is that the obsession with big tech as a representation of tech as a whole gives a distorted picture of things. Getting closer to reality in this matter is one big challenge.

There are some Clojure-ecosystems things that are pretty cool, too, that you'd probably miss going into Haskell. lacinia is an extremely cool GraphQL library, and there are a variety of interesting datalog-based datastores which are spiritual descendents of Datomic, notably xtdb (formerly crux) and datalevin. Also as noted, you can write the front-end in ClojureScript if you want to, and there are a lot of cool libraries for that as well.

Now, I noticed a ways back that Clojure 1.0 added the tap> function, and I vaguely knew it would be helpful for this kind of thing; I finally got around to trying it out to debug some hairy NullPointerException bugs in Lacinia.

Part of this was due to some inefficiencies in Lacinia, since corrected, but we also found other hot-spots specific to our application's code.

Physicist here. Made a kind of Physics Puzzle Game. The Github Code proofs that you do not need a backend (in a first step you only want to read and not write external files anyway). Here is what you do: 1) Sign up to and install Github, this all important step is taken for granted by any community in any language but never taught to Phyiscists. 2) Decide to use ClojureScript for your game :-) 3) Look at and reproduce the Shadow-cljs quick start 4) Using Git, clone the Shadow-cljs browser example 5) If you do not know Emacs, install VSCode+Calva 6) Understand the following two Paredit operations in Calva: ctrl+right for ForwardSexp and ctrl+left for BackwardSexp. 7) If you come to this point, try to include reagent into the shadow-cljs example.
