I’ve been tempted to write a little webcomponent or polymer or so integration with it to see how it works, be a nice little bite-size thing to test with.

Nice! Let me know how it goes. I had written a small React example before for a local meetup, but never posted it online. I’m going to try to do that this week.

Hello I just published the latest version of Elixirscript. For a full list of the changes, take a look at the changelog The major changes in this version are:

• Can select between ES, CommonJS, or UMD module formats for output
• Can use and compile dependencies in mix projects (if dependency has the elixirscript compiler in its mix compilers)
• Default input and output paths in mix projects

There is now an elixirscript organization with the projects that it uses. Also there is a newly created blog with the first post giving more details about the majors changes.

Finally, a gitter room was created for the project. The elixirscript channel on the elixir-lang slack still exists and I’ll still be there. The gitter room allows for integrations and keeps the history.

• Hex: https://hex.pm/packages/elixir_script
• Release on Github: https://github.com/elixirscript/elixirscript/releases/tag/v0.25.0

Ooo, awesome an update!

Elixirscript 0.26.0 has been released. The biggest change is that output is reduced to a single file.

@OvermindDL1 I’ve been looking at BuckleScript a lot lately. I know you are a fan of it. I’m wondering how do you like its JavaScript interoperability? Redirecting to bucklescript.github.io/bucklescript

Wondering if maybe there are some things there that are worth borrowing for Elixirscript

It’s Javascript typed bindings are just done via OCaml’s normal FFI system, it just all fit very well.

But yeah, I’d probably do something similar in Elixirscript. Last I saw Elixirscript you still did the JS.import bit (though now removed according to your just-now changelog ^.^), I’d probably do something like:

defjsmodule Underscore, import_name: "_" do
  deffun blah/2
end

Or whatever, although you could add typing information like I’m doing in TypedElixir so you can cause compile-errors when interfaces are mis-used.

But yeah, OCaml’s FFI is just typing the interface, which the compiler then resolves to JS modules, it is very succinct and powerful and safe, as well as hard to borrow without having types in Elixir. ^.^

Ah that makes sense. Eventually I would like to get it to the point of requiring no JavaScript at all. It’s partially what the JS module is for right now, but could be built up to allow for more. The 2 systems that have impressed my so far are BuckleScript and Scala.js. But I guess both of those are type heavy examples. Anyways, I think there are somethings that can be done to get closer to that goal

@bryanjos: I saw docs at github and have some questions:

1. Do you support converting whole Elixir project into JavaScript app?
   I mean not only specified directory, but also config, tests and others?
2. Is it possible to prefix JavaScript calls in Elixir code? :console.log("hello") => :js.console.log("hello"). This could conflict with libraries (I mainly think about :document).
3. I have a problem with last (4144) line: export default Elixir;, I got error message: SyntaxError: export declarations may only appear at top level of a module in Firefox Nightly and Uncaught SyntaxError: Unexpected token export in Chrome.

@Eiji

1. Right now only a specific directory. I haven’t tested converting config or tests.

2. Not possible right now, but something that could be up for discussion. I know clojurescript does something similar and it may be a good idea here. There is the “JS” modules which can be the jumping off point for that.

3. Try using the “umd” format instead. The default is “es” which isn’t supported by browsers just yet

Edit: I probably need to do a good sweep of the docs to make sure they are up to date
