With Lispy languages, you can do whatever you want without worrying too much about underlying web server, db, etc. I use my own constructors like: (define-crud-handler :employee [:path [customers cust-id sites site-id employees] :auth-required? true] {:collection {:create (employees-create

Has anyone here had a chance to use Silk for a project they'd be willing to share? I'm a front-end web-dev newbie who has been researching server-side Om/React rendering, and it seems like Silk is ideal for this use case. However I'd be much more comfortable starting out if there were some

To be fair, Cursive doesn't yet provide a great CLJS REPL solution either, although that is coming soon. Right now, for ease of getting a CLJS REPL up and running Light Table definitely wins. On 8 October 2014 05:20, gvim gvi...@gmail.com wrote: On 11/04/2014 09:17, Colin Yates wrote: * you

It's not about 'safety' (depending on what that means in this context), but as Zach pointed out, if you aren't careful about backpressure you can run into performance bottlenecks with unrestrained async IO operations because although they let you code as if you could handle an unlimited amount

2014-10-07 Thread Laurent PETIT
