CoinStats - A NodeJS Cryptocurrency Statistic Bot - New Graph & Cleaning output folder

CoinStats

What feature(s) did you add?

Changelog:

• Added a new overview graph, showing the percentage change of the last 7 days for each coin
  
• Added a new config option to toggle auto posting to steemit
• Added a cleanup function and utils class to remove all images after uploading
• Graphs now have a title

How did you implement it/them?

The new utils.js which uses the file system to remove all images:

var fs = require('fs');

var clearImgFolder = function () {
    var path = './img';
    if (fs.existsSync(path)) {
        fs.readdirSync(path).forEach(function(file, index){
          var filePath = path + "/" + file;

          fs.unlinkSync(filePath);
        });
    }
}

module.exports = {
  clearImgFolder: clearImgFolder,
}

The new graph is done by changing the graphdata and the config.json got a new key 'should_post_to_steemit' which defaults to true.

if (!config.should_post_to_steemit) {
        console.log('Not uploading to Steemit - Abort');
        return;
}

Roadmap

  • Bar Charts shows only percentage change over last week
  • Toggle Steemit auto posting via config
  • Clearing img/ folder after upload
• V.0.4:
  • Layout changes
• V.1.0:

  • Running on a Server and automatically post every day
  • Custom messages for the coins
