It would be supercool to see something like this using websockets.

nickik2• 15 years ago

I have not jet seen a ClojureScript-to-Clojure websocket library thing. Would be cool to see.

Here is a good example of ClojureScript <-> Clojure communication https://github.com/neotyk/ws-cljs It uses the Aleph Clojure library on the server side.

ClojureScript is the only compile to JS language that I'm aware that lets you fully leverage the power of modifying JavaScript prototypes w/o fear of gross incompatibilities:

http://clojurescriptone.com/documentation.html#one.color

Note that they've extended (safely because of namespaces) browser natives including Element, Array, String, as well as the custom ClojureScript data types to respond to the color function.

Thanks for putting that together, especially the documentation! I think that I would save a lot of time, eventually, using a uniform Clojure development environment for server side and client side, but I am hesitant to spend the learning curve time right now. (Clojure, Noir, and Javascript are working out really well for me.)

Your good job on documentation will get me to spend the learning curve time sooner than later.

I also do work using GWT and SmartGWT and the uniform development environment (even if it is Java :-) really helps work flow.

Don't thank me, thank fogus & Clojure/core! :)

You guys are doing excellent work. I also find what you are doing with predicate dispatch very interesting. I think that class of methods are/will be really powerful - especially for big complicated programs. Have you been able to get it to work efficiently for most cases in clojurescript and in general?

swannodette4• 15 years ago

We're not quite there yet with predicate dispatch. However if the pattern matching benchmarks are any indicator, it will be plenty efficient. Definitely excited about it, but it might be some time since it will require some well considered synergy between core.logic and core.match.

How do I [intelligently] choose ClosureScript over say, Node.js?

swannodette4• 15 years ago

You don't have to choose one or the other. You can target Node.js with ClojureScript.

rgbrgb2• 15 years ago

But then you're missing one of the best features of developing with Node.js (one less context switch).

jsavimbi2• 15 years ago

What I meant to say is "based on ecosystem, performance, scalability and learning curve, is there a compelling argument that would convince me to change from my current language/framework/platform to this one?"

rgbrgb2• 15 years ago

This is definitely a question worth asking. I think the audience ClojureScript is most appealing to is those who are already writing server-side stuff in Clojure and want to have a consistent front end or "old-school Lisp hackers" who are now writing web applications.

Personally, I'm attracted to Lisp/Clojure because of its AI history but haven't put the time in to build anything real with it yet. Are there people who have switched away from (Node || Python || Ruby) && JS who could discuss their experience?

jshen2• 15 years ago

I've done Ruby for years and I've written one large commercial project in clojure. Clojure was great, and I would love to use it more, but I haven't been able to convince people to use a lisp.

It's very strange actually, I tried really hard to do a small project in clojure at my current job and got resistance from everyone. These same people were happy to try coffee script, scala, golang, etc, etc. There seems to be a true bias against lisps.

jlongster• 15 years ago

Pros and cons. Switching away from a mainstream language is hard; you lose the community and all the work going to it. But you gain a lot of technical power, and possibly find a small community of really smart people.

Sometimes you can get the best of both worlds by doing something like ClojureScript, which is to compile to a mainstream language. That is compelling.

In the end, Lisp is really powerful, it's better than other languages, and it's worth learning. If you can deal with the lack of a huge community, you'll be fine. Clojure is gaining quite a large following, actually, so it's one of the best environments to learn Lisp.

adeelk• 15 years ago

I’m a Clojure user that switched from Python. We’re now using it at the startup I founded. So far it seems to have been a great decision.

lukev2• 15 years ago

You have to start by comparing apples to apples. ClojureScript is a programming language which compiles to JavaScript, Node.js is a runtime platform which executes JavaScript.

So in this case you can actually use both.

MatthewPhillips• 15 years ago

Looks great. What I would love to see is a ClojureScript tutorial that doesn't assume you already know Clojure.

edoloughlin• 15 years ago

ClojureScript is a subset of Clojure, so you do need to more or less know Clojure. The main benefit to ClojureScript is that you can use essentially the same language on the front- and back-ends.

amouat• 15 years ago

Yes, but it doesn't really mention that in the documentation. It would be good to something along the lines of "You will need to know Clojure to use ClojureScript One, go here to learn it".

This looks excellent though - I'll give it a go once I think of a toy project to try it with.

pavpanchekha• 15 years ago

I assume this is just-launched, but being able to do examples online would be amazing. I believe ClojureScript does not include (eval) so you'd have to route to the server and back; perhaps this is feasible?

icefox• 15 years ago

There is a clojure jail so yah it is feasible.

rman6662• 15 years ago

From a design perspective, that is one sweet looking site! Who created it? With what?

rman6662• 15 years ago

Okay, that was kind of a dumb question. I assume it's created using ClojureScript One. What I meant was how was the visual design created?

raju• 15 years ago

This podcast from Relevance - http://thinkrelevance.com/blog/2012/01/12/podcast-episode-00... talks about the development of ClojureScript One, and names a few people responsible for the visual design.

I believe Jen Myers (@antiheroine) is one of them.

c_t_montgomery• 15 years ago

View -> Source on this page. Just do it.

paulkoer• 15 years ago

Yes, do it! The people downvoting you obviously didn't!

johanmagnusson• 15 years ago

Or they did it but only on the first page. What you should look at is the source for the documentation page (http://clojurescriptone.com/documentation.html).

aveeno• 15 years ago

How good is the interop with existing js libraries? Would i be able to use webgl or three.js?

asmala• 15 years ago

The short answer is yes, ClojureScript has similar interop features for vanilla JS as Clojure for the JVM has for Java.

However, given that ClojureScript uses the Google Closure compiler to optimize production code, there are a few gotchas to be aware of. This article does a great job at explaining the details:

jcdreads• 15 years ago

Thank you very, very much for this.

Note: Installing failed for me until I replaced git:// with https:// in two places in script/deps. Then it worked.

candera• 15 years ago

Thanks for pointing that out. We've fixed it and pushed the new script.

jsofra• 15 years ago

Strange for me it was he other way around. I had to replace https:// with git:// , perhaps it depends on the git version? mine was probably pretty old.
