V8 engine for Elixir with pools
Home Page: http://leopard.in.ua/elixir_v8/
My name is Oleksii Vasyliev.
I work as a Software Engineer. For more information about me, check out this links:
I am trying to run this within phoenix and I get the error: Could not compile dependency erlang_v8, ~/.mix/rebar command failed. If you want to recompile this dependency, please run: mix deps.compile erlang_v8. Any ideas?
In my personal project, after I put {:elixir_v8, "~> 0.2.2"} as deps in mix.exs, hit $ mix deps.get and $ iex -S mix, I see this:
Erlang/OTP 19 [erts-8.2] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false]
Compiling 1 file (.ex)

Did I miss something?
Have you had any success including node libraries like 'request' or others? I would like to add the ability to make http calls? what about jquery?
Here is a simple elixir script running totally fine.
ElixirV8.create_pool(:main, 10, file: "a.js")
IO.inspect ElixirV8.eval({:global, :main}, "a()")
But when the "a.js" gets larger, it shows error like this.
[pig@localhost phoenix_react]$ ls -lh a.js ; mix run run.exs
-rw-r--r-- 1 pig pig 130K Feb 25 10:40 a.js

It's nicer when it prints kinder error message or document about it in readme.
