This is my lightning talk submission to ReactiveConf 2018 https://reactiveconf.com/

In this talk, I want to share my experience gained during the development of frontend applications in several programming languages.

I think it's not a secret for anybody that developing large JavaScript applications is not so easy as it seems at first glance. We all want something simpler and more reliable. Therefore, many developers and even entire companies switch to different, compiled in JavaScript, programming languages. The bulk of such transitions is accounted for TypeScript and flow, and often, developers faced with more problems than they were before.

I wasn't the exception. Moving to a new project, I started using TypeScript and was disappointed. Luckily in my next project I used ClojureScript and it was like everything is illuminated!

Code Splitting

NOTE: This gist uses the master branch of ClojureScript. Clone ClojureScript and from the checkout run ./script/bootstrap and ./script/uberjar. This will produce target/cljs.jar which you can use to follow this guide.

As client applications become larger it becomes desirable to load only the code actually required to run a particular logical screen. Previously ClojureScript :modules compiler option permitted such code splitting, but this feature only worked under :advanced compilation and users would still have to manage loading these splits. :modules also required manual

/*
  Incredibly simple Node.js and Express application server for serving static assets.
  
  DON'T USE THIS IN PRODUCTION!
    It is meant for learning purposes only. This server is not optimized for performance, 
    and is missing key features such as error pages, compression, and caching.
  
  For production, I recommend using an application framework that supports server-side rendering, 
    such as Next.js. https://nextjs.org

;; React supports "refs" as a way for a component to get a 
;; handle to its children. Classically, refs were string-based.
;; Recent versions of React support callback attributes as a
;; more elegant variant of accessing DOM notes or components.
;;
;; This example uses a Form-3 component as per
;; https://github.com/Day8/re-frame/wiki/Creating-Reagent-Components
;; 
;; For callback refs, see React's documentation

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.
