Execjs
Execjs
allows you run JavaScript from Elixir. It can automatically pick the
best runtime available on the system.
Runtimes
Execjs
supports the following runtimes:
Use the application environment (application key: :execjs
, key: :runtime
)
to set the runtime Execjs
uses. Alternatively, the EXECJS_RUNTIME
environment variable can also be used to set the runtime.
Usage
eval
iex> Execjs.eval "'red yellow blue'.split(' ')"
["red", "yellow", "blue"]
compile
/call
iex> {source, 0} = System.cmd("curl", ["-sL", "--compressed", "https://rawgit.com/jashkenas/coffeescript/master/extras/coffee-script.js"])
iex> context = Execjs.compile(source)
iex> Execjs.call(context, "CoffeeScript.compile", ["square = (x) -> x * x"])
"(function() {\n var square;\n\n square = function(x) {\n return x * x;\n };\n\n}).call(this);\n"
