Javascript Code For Working With Hive, Steem And Blurt

[droida]

Previous Version

Before HF24, Hive property names were the same as those from Steem, and the library that I used was this one: @droida/3-blockchains-1-program.
After that, symbols and property names changed, and some API calls were not working using the same require instruction. So I had to adapt my scripts.

Because I wanted to make the minimal amount of change in my existing scripts, I use newhive as argument for operations not working with the Steem library, eg transfer. Here is my library for working with the 3 blockchains.

chainlib.js

var currentChainName="steem";
const chain=require("steem");
const hive=require("@hiveio/hive-js");

module.exports = {
    /**
     * @argument {String} name the blockchain name (newhive for transfer and claim rewards)
     */
    getChain: function(name) {
        if (name && name!=currentChainName) {
            currentChainName=name;
            if (name=='steem') {
                chain.api.setOptions({ url: 'https://api.steemit.com' });
                chain.config.set('address_prefix','STM');

                chain.config.set('alternative_api_endpoints', ['https://api.steemit.com', 'https://api.steemit.com']);
                return chain;

};

Example

The blockchain name is passed as a command line argument.

#!/usr/bin/node
const chainlib=require("./chainlib.js");

const chain=chainlib.getChain(process.argv[2]);

chain.api.getDynamicGlobalProperties(function(err, result) {
  console.log(err, result);
});

Quicktrades

I published this small library mainly because @quicktrades now uses it for trading in Hive and Steem internal markets. The release will be out in the coming days.

Great script with useful application for the users of both chain.

I will return the 10BLURT as soon as I claim my post rewards. I would like to ask you @droida if you can help me create an account on BLURTTER.

[droida]

OK. Just write the desired nickname and the email address to send the password to, or write to droida#3806 on Discord.
