[Steem-red] - Content and Witnesses nodes for Node-RED

Steem-Red is a series of nodes from the Steem Js library that can be used in Node-Red by just dragging and dropping them into the flow chart. It allows users to quickly interact with the Steem blockchain without needing to write a big amount of code (and for simple actions, code is not needed).

Changes made

---

Methods from Content and Witnesses were added to the nodes leaving out the following nodes:

Content:

• getContent
• getContentReplies
• getDiscussionsByAuthorBeforeDate
• getRepliesByLastUpdate

Witnesses:

• getActiveWitnesses
• getMinerQueue
• getWitnessByAccount
• getWitnessCount
• getWitnesses
• getWitnessesByVote

Also, descriptions were fixed for each of the nodes and color were added to differentiate the category of each one. So, here is an example of how it looks:

Requirements

---

To run the nodes on your localhost you must have Node-RED installed on your localhost. Node-RED can be installed by running the following command in your terminal:

$ sudo npm install -g --unsafe-perm node-red

Installation

---

$ git clone https://github.com/jayserdny/node-red-contrib-steem
$ cd node-red-contrib-steem
$ npm install

To install the node modules on your localhost, install it into your Node-RED runtime.

$ sudo npm link
$ cd ~/.node-red
$ npm link node-red-contrib-steem

Run node-red.

$ node-red

Open a browser and go to the address http://127.0.0.1:1880.

Usage Example

---

Here is a quick example (not a tutorial) of how a flowchart looks if an user wants to return the number of accounts in Steem and the number of witnesses:

There is an infinite set of things that you can do with this such as create endpoints and functions to parse data from the blockchain easily, filter data in a certain query, etc.
