ExBuilder

Simple library to support Ruby style jbuilder-like JSON templates. Templates should be placed into web/templates directory and have builder extension. All templates will be compiled into functions and available via ExBuilder.Template module. Parameters, passed to the generated function as a keyword list, are available inside template via assign/1 macro.

Sample test cases:

iex> document do
iex>	object(:sample, %{name: "Joe"})
iex> end
%{sample: %{name: "Joe"}}

iex> document do
iex>   name = assign(:name)	
iex>   property(:name, name)
iex> end
%{sample: %{name: "Joe"}}

iex> document do 
iex>	object(:sample, %{name: "Joe"}) do
iex>		object(:children) do
iex>			object(:child, %{name: "Phil"})
iex>		end
iex>	end
iex> end
%{sample: %{name: "Joe", children: %{child: %{name: "Phil"}}}}

Using ExBuilder.Template with simple Plug application

1. Place following code into template file in web/templates/sample.builder. Note that Eex style variables @var_name can be used inside templates in the same way assign(var_name) is used

	names = assign(:children)

	object(:person) do
	    property :name, @name 
	    object(:company, @company)
	    array(:children, names) do
	    	%{name: item}
	    end
	end

1. Add use statement for ExBuilder.Template

	
	defmodule MyApp.Api do
		use Plug.Router

		plug :match
		plug :dispatch

		use ExBuilder.Template
		
		get "/info" do
		
			send_resp(conn, 200, render_json("sample", name: "John Smith", children: ["Jeff"], company: %{name: "Company Name"}))
		end
	
	end
