4. Why Clojure? Monday, April 29, 13
5. Clojure as Ecosystem • Mature ecosystem of JVM • Interactive development (REPL) • ClojureScript • Leiningen • Emacs/Vim/SublimeText?? • Datomic Monday, April 29, 13
6. Clojure as Language • Rapid development • Concurrency • FP • Metaprogramming • DSL • Data centric Monday, April 29, 13
7. Clojure + Web Monday, April 29, 13
8. Clojure + Web • Ring - HTTP abstraction (WCGI, Rack, Hack) • Compojure - routing DSL (Sinatra, Scotty, Scalatra) Monday, April 29, 13
9. Functional Web Architecture https://speakerdeck.com/weavejester/functional-web- architecture Monday, April 29, 13
10. Clojure Web Toolbox • Auth - Friend • JSON - data.json, cheshire • Validation - lib-noir, Validateur • Testing - Kerodon, Peridot • Logging - tools.logging • XML - data.xml, data.zip • SQL - Korma, clojure.java.jdbc • Deploy - Leiningen • HTML - ... • CRUD - ? • Performance - Grinder Monday, April 29, 13
11. Libraries vs Frameworks Monday, April 29, 13
12. Libraries • Easy to compose • You have to know ecosystem • You are not limited what you can build and how to build it • You have to create your own architecture Monday, April 29, 13
13. Frameworks • Take care of users (security, ...) • Basic architecture • Defaults (Libraries) • Docs, tutorials, guides, ecosystem • Habits • Limitations (what..., how...) Monday, April 29, 13
14. Existing Frameworks • Conjure • Noir • Joodo • Pedestal • Luminus Monday, April 29, 13
15. Origins • Noir • Noir + lib-noir • lib-noir • lib-luminus + Luminus • lib-noir + Luminus Monday, April 29, 13
16. Luminus • Freedom (up to you what and how) • Utilize existing Clojure ecosystem • Libraries composability • Flexible templates • Basic architecture • Defaults • Documentation • Take care of newcomers Monday, April 29, 13
17. Improvements • Improve profiles system • Improve architecture • Add profiles* • Write guides, tutorials, docs Monday, April 29, 13
