nova_json_schemas

Nova plugin for validating input data against JSON schema.

Usage

First include nova_json_schemas in your rebar.config file:

{deps, [
        {nova_json_schemas, {git, "https://github.com/novaframework/nova_json_schemas.git", {branch, "master"}}}
	]}.

Update your router to make use of this plugin and to tell where JSON-schemas for each route will be located:

routes(_Environment) ->
    [
      #{prefix => "",
        security => false,
	plugins => [
		   {pre_request, nova_json_schemas, #{render_errors => true}},
                   {pre_request, nova_request_plugin, #{decode_json_body => true}}
		   ],
	routes => [
	       {"/my_route", {my_controller, do_something}, #{extra_state => #{json_schema => "./schemas/my_schema.jsons"}}}
	         ]
	}
    ].

Note! You need to invoke the nova_request_plugin with decode_json_body set to true AFTER the nova_json_schemas in the list since Nova runs the plugins bottom-up.

Then put my_schema.jsons that contains the schema in your priv/schemas/ directory (json schemas is read related from priv-directory of your main nova application).
