Re: [ClojureScript] Re: Any chance we can fit ClojureScript into Webpack ecosystem?

It would be nice if we can require ClojureScript in JavaScript, and let
Webpack to handle so many issues.

For Webpack use cases, I tried to sell ClojureScript to other front-end
developers around me, but saw some problems:

* IMPORTANT: hard to install JVM. For JavaScript projects, installing
Node.js(with npm inside) would be okay. It's very hard for JavaScript
developers to pick up JVM and Boot(or Leiningen).
* IMPORTANT: long time caching and code splitting. We use these features in
production for years. But I don't see a good solution in ClojureScript.
* Async code loading. For large projects some code can be loaded when a
router is activated. No good solution found in ClojureScript.
* Assets bundling. Now we rely on Webpack to do that, result in using 2
tools.

Not sure if they can be solved if we have a ClojureScript running on
Webpack. But there are many compiled-to-js languages support those features
in by supporting Webpack already. That's the purpose behind the post.

Didn't try `node-jre`. I'm guessing we still need to debug JVM stuffs since
it's running JVM?

I'm from the JS side as well, so I'm glad to see this question!  Are you 
imagining something like the following?  We should probably start by imagining 
why someone would want to require cljs this way and if it would even make sense 
to:

```
require('cljs!./src-cljs') // return all goog.provided namespaces?
require('cljs!./src-cljs/foo/core.cljs') // return a single goog.provide 
namespace?
```

Either way I think it would need Closure Compiler to return a single asset for 
each require statement, if I understand webpack correctly.

It's worth mentioning that the recent "node-jre" package allows users to 
install/use the full cljs JVM compiler in its fully glory through npm without 
any external dependencies, which I've tested here: https://github.com/cljs/tool

I think it's possible—just unsure of webpack use-cases.  Thoughts?

[ClojureScript] Any chance we can fit ClojureScript into Webpack ecosystem?

2017-05-11 Thread Jonas Kello 
ReasonML can be compiled by bucklescript loader AFAIK. However I think that 
will make it compile slower.

[ClojureScript] Re: Any chance we can fit ClojureScript into Webpack ecosystem?

2017-05-11 Thread Thomas Heller 
IMHO the webpack ecosystem and CLJS can live happily side by side, why is it 
important that they know about each other? Good JS interop ensures that both 
sides can interact well.

What would you expect from a loader that you'd be willing to give up the 
Closure Compiler?
