** Introduction

This document describes the architecture of GN2. Because GN2 is
evolving, only a high-level overview is given here.

** Webserver

The main [[https://github.com/genenetwork/genenetwork2][GN2 webserver]] is built on [[http://flask.pocoo.org/][Python flask]] and this GN2 source
code can be found on [[https://github.com/genenetwork/genenetwork2/tree/master/wqflask/wqflask][github]] in the wqflask directory. The routing
tables are defined in [[https://github.com/genenetwork/genenetwork2/blob/master/wqflask/wqflask/views.py][views.py]]. For example the main page is loaded
from a template named [[https://github.com/genenetwork/genenetwork2/blob/master/wqflask/wqflask/templates/index_page.htm][index_page.html]] in the [[https://github.com/genenetwork/genenetwork2/tree/master/wqflask/wqflask/templates][templates]] directory. In
the template you can find get the form gets filled by a Javascript
routine defined in [[https://github.com/genenetwork/genenetwork2/blob/master/wqflask/wqflask/static/new/javascript/dataset_select_menu.js][data_select_menu.js]] which picks up a static JSON
file for the menu. This static file is generated with
[[https://github.com/genenetwork/genenetwork2/blob/master/wqflask/maintenance/gen_select_dataset.py][gen_select_dataset.py]].  Note that this JSON data will soon be served
by gn_server, see [[#gnserver-rest][GnServer (REST)]].

** GnServer (REST)

The [[https://github.com/genenetwork/gn_server][GnServer REST API]] is built on high performance [[http://elixir-lang.org/][Elixir]] with [[https://github.com/falood/maru][Maru]].
