Market trade processor

A NodeJS \ Express \ Socket.io application that receives JSON messages sent via HTTP POST request. JSON input messages are validated before the request is completed. Posted messages will be added to a frontend table and paginated dynamically with Datatable. Messages are store in json files and their names have the format of a MySQL timestamp.

Frontend

I'm using swig template engine. All html views are in the views directory.

This endpoint will accept a raw POST string in JSON format:
