New Features

I would like to introduce version 0.2.0 a minor release which has so many improvements and reliable stream algorithm
also, it has some new features and has faster process algorithms and better catch for each target for all methods as well as some breaking changes.

Account Mentions

commit
If someone mentioned an account in a comment or a post it will be detected directly thanks to this new method, it also comes with multiple accounts support instead of creating an instance for each account

Also, a simple regex is being used to filter the comment/post body then it being matched with the user input mentions accounts.

The following code is the core operation for this method.

const transactions = await blockchain.getTransactions();
for (const trx of transactions) {
  const [txType, txData] = trx.operations[0];
  if (txType === 'comment') {
    const mentionAccounts = txData.body.match(/\B@[a-z0-9-.]+/gm);
    const mentionTargets = accounts
      ? accounts.map(name => {
        return `@${name}`;
      })
      : [];
    const setMentions = accounts ? mentionAccounts.some(name => mentionTargets.includes(name)) : true;
    if (mentionAccounts && setMentions && trx.transaction_id !== latestCatch) {
      latestCatch = trx.transaction_id;
      yield trx;
    }
  }
}

Account Counter

commit
This method is supposed to stream each count when someone signs up
by a simple algorithm

let latestCatch;
const count = await api.getAccountCount();
if (count && latestCatch !== count) {
  latestCatch = count;
  yield count;
}

Now when any new account register will be streamed directly by using the iterator stream algorithm.

Funds Tracker

commit
I've made some improvements for this method to be reliable and faster, I also have prepared this method for multi-tracking by using an options parameter as an object. it will handle the multi variable as a boolean
Also, I've implemented the async iterator stream algorithm.

The multi-tracking for future I've been working on it but I didn't publish it yet it will be ready in next versions.

Support multiple accounts

Now all single account params methods now accepting multiple accounts.
This gonna be an array which contains an account name instead of just a single account string as a parameter.

Then this code for multiple accounts validation

accounts.every(account => validateAccountName(account) === null)

New Structure & Iterator streams

commit

In the old version, I've been using a blockchain as a helper file for each method, all in one file.
But now I've separated all methods for easier maintenance and development.

Also, the module has been moved from dsteem as a dependency to steem-js as dsteem no longer updated since 6 months ago.
and also because some utilities not available in dsteem also I can see that steem-js is currently stable and reliable for SteemRadar.js.

The folder structure has been changed now blockchain is a prototype for the scan class beside utopian.

Breaking changes

The following methods have been renamed.

//old
scan.blockchain.accounts()
//new
scan.blockchain.accountActivity()

//old
scan.blockchain.security()
//new
scan.blockchain.accountSecurity()

I've made some improvements to existing methods to be an alternative for others.
The following methods have been removed from SteemRadar as there are other alternatives.

Utopian vote stream

// Removed
scan.utopian.vote()
// Alternative
scan.blockchain.votes()

Memo stream

// Removed
scan.blockchain.memo()
// Alternative
scan.blockchain.transfers()

Implementation

if you already have the older version you can update this package by the following command

$ npm update

or you can install the package by the following command

$ npm install steemradar

Create new instance

const steemradar = require('steemradar');

const scan = new steemradar.Scan();

I'm going to explain how to implement the new features only for other features please read the documentation

Stream or detect any account mentions from blockchain comments/posts

  const accounts = ['utopian-io'] || null;

  const stream = scan.blockchain.accountMentions(accounts);
  stream.on('data', trx => {
    stream.pause(); // Pause this operation use resume() to resume
    stream.destroy(); // Destory this operation
  });

Stream account counting from blockchain

  const stream = scan.blockchain.accountCounter();
  stream.on('data', trx => {
   console.log(trx);
    stream.pause();
    stream.destroy();
  });

Testing

For testing all methods please use the following command

npm test

What's next?

A new major release:

• Some breaking changes
• Rename all scan aliases to start with get
• Complete funds tracking algorithm for multi-tracking
• A new method for comments
• A new method for posts
• Full streaming methods for utopian.rocks
• Improve library code readability & documentation
• Reduce the dependencies (by built-in alternatives)
• Sperate command-line utility in a different repository to reduce the dependencies and library size.
