Om Next - David Nolen

I have nothing to say on Lein vs Boot, but I'm a long-term emacers with > 10 years and I can't endorse Cursive strongly enough. I've got easily at least 1k hours in my .emacs.d. Suffice it to say, it takes a lot to take away from Emacs/SLIME. Never bought into the Textmate hype during the Ruby days, or the SublimeText hype subsequently because Emacs already had all that functionality if not out of the box, there certainly was someone with an .el I could borrow. It takes a lot for me to leave Emacs, especially for a LISP. Here's my 2 cents - Cursive is worth it . (Hey Ideogram folks, if you want an endorsement, feel free to use that paragraph in exchange for a lifetime license ;)). For one-off-scripts, for back-end solutions, and what tipped me over the edge, it's CLJS script integration goes beyond acceptable -- it's actually fun to work in-- Cursive is my go-to. Om and Figwheel (optionally with Prismatic Schema if you like type guarantees) makes web development's feedback loop a lot tighter. Rich Hickey assembled a team of just insanely talented and charismatic(1) developers who not only are a) remarkably intelligent but b) know when to steal ideas and integrate them [none of that too-proud-NIH-syndrome there], and c) know how to interact in a way to that is community-feedback-positive(2) so people contribute.

Sorry if it wasn't apparent but I agree / advocate strongly for what you mention, and we use that model at my company. If you look at how Om evolved though, it started out with that simple model of passing the state object down to child components. Then cursors were implemented to make it easier to pass around parts of your global state without having components needing to know everything. GraphQL doesn't mean moving to stateful components, it's just a nicer way to have a singleton data store because instead of chunking and passing a map around, components can declare which data they need. In that system components are still read only, and dispatch to external pure functions. David Nolen does a great job talking about the trade offs and the evolution of everything in this talk ▶ this video I highly recommend it!

> ...but right now we're focusing on building stuff instead of playing with languages Which is exactly what's so compelling with regard to ClojureScript and say Om or any one of the React wrappers out there: you guys already use Clojure and ClojureScript and its libraries are incredibly pragmatic and designed for "real work". CoffeeScript would seem more like language play than ClojureScript, but of course I'm speaking as an outsider. :) Also if you haven't already, take a look at David Nolen's recent talk on Om Next[1]. Personally if I were using Clojure on the backend, I'd be pushing hard for it on the frontend too. [1] ▶ this video

Any idea why they decided to use string-based queries for GraphQL? I feel something that can be composed programmatically without having to deal with string concatenation like Falcor's queries or the Datomic Pull syntax proposed in Om Next [1] could be more flexible and robust. I may be missing something. [1] ▶ this video
