Recently I announced a new opensource project: https://steemit.com/onsteem/@mahdiyari/announcement-onsteem-a-better-interface-on-the-steem-blockchain

I started developing back-end for this project called Dblog.io (new name)!
We will have a back-end here and a front-end here

A demo will be available here: https://dev.onsteem.com (back-end and front-end connected)

Codes

Note: if you are not a developer, you can skip this part!

Explaining the structure of dblog-backend:
Main server file is api.js which will be started with npm start
The config file is config.js which includes all needed variables!
Under the /conf/ folder, needed configurations will be added. Currently, we have steemconnect/index.js for initializing steemconnect and /mysql/index.js for creating a MySql connection.
Under the /blockchain_apis/ needed RPC calls will be added. Currently, there is a database API get_dynamic_global_properties.js
Under the /login_apis/ needed functions for the login process will be added. Currently, we added a confirm_process.js for assigning a unique hex string (called hashKey) to the logged in users.
We will keep that unique hashKey instead of access_token (access_token provided by steemconnect and used to upvote, comment, and etc) in the database for validating other operations which will help to reduce security concerns.
confirm_process will check to see there is any hashKey in the request, then it will check that hashKey against the database. if there was not a hashKey in the request, confirm_process will assign a new hashKey for that user after checking login credentials.
We will use dynamic_global_properties in the front-end for some calculations. Like converting VESTS to the STEEM
