New Project: SteemPlus backend

What is the project about?

We are working hard to bring the whole lot of new tools that the community needs but in some cases, querying the blockchain can be too slow to present results in a timely manner. That is why we have decided to start using SteemSQL for some of our features.

SteemSQL is a well maintained and frequently synchronized database proposed by @arcange that allows to access blockchain data in a super fast way.

Since SteemSQL is a paying service (10SBD/month) and requires login credentials, I couldn't expose those information directly on the extension and had to create a backend. The primary purpose of this backend will be to provide APIs that fetch the SteemSQL data.

Existing features

As of today, the backend returns data on the two following endpoints:

• /api/get-witness/[username] : Gets a lot of data on a witness : its rank, last mined block, missed block and much more (See result hereunder)

{"lastBlockTimestamp":"2018-04-15T09:22:06.000Z","rank":"81","name":"stoodkev","votes_count":403,"created":"2018-01-24T03:55:09.000Z","url":"https://steemit.com/witness-category/@stoodkev/my-witness-thread","votes":"3618732607143144","total_missed":4,"last_aslot":"21649642","last_confirmed_block_num":"21584758","signing_key":"STM7wEZ2Sj1embiofddWjkRHDDA5EZfcEPmdLN7Pbc4X8afrRCX9n","account_creation_fee":0.2,"account_creation_fee_symbol":"STEEM","maximum_block_size":131072,"sbd_interest_rate":0,"sbd_exchange_rate_base":2.674,"sbd_exchange_rate_base_symbol":"SBD","sbd_exchange_rate_quote":1,"sbd_exchange_rate_quote_symbol":"STEEM","last_sbd_exchange_update":"2018-04-15T11:04:45.000Z","running_version":"0.19.2","hardfork_version_vote":"0.0.0","hardfork_time_vote":"2016-03-24T16:00:00.000Z"}

• /api/get-mentions/[username] : Gets mentions of [username], both from posts and comments. Body is truncated for a better execution speed.

Technology Stack

We used Node.js and Express framework to create our backend.

Roadmap

In a first time, we will keep using this backend to fetch more information from SteemSQL such as:

• Wallet information
• Delegation received
• Witness votes received
• Whatever else I will think of during my sleepless nights!

In the future, it might also include some non-SteemSQL algorithms, but I ll keep that a secret for now!

List of commits

• Detailed README including instructions to run it locally and information about the endpoints.
• config file
• API
