Introduction

Dtube is a video plateform based on the steem blockchain that store videos on IPFS. Because most of users doesn't use ipfs. Dtube is a central point that will store content on IPFS node.

Dtube community support is a bot that will "listen" for new dtube content for a specific steem tag and store the video on a local IPFS node. Plus it stores metadata about dtube content like title (steem post) / video size / permlink / author. The main goad is to persist dtube content of your favorite community on IPFS.

DCS will retrieve 480p videos. if not available, it will retrieve the source file.

New-features

here is the list of new features :

• List all content (by date, by size, by author)
• List all content with a markdown format
• Add specific content based on the dtube url
• remove specific content based on the pinset
• failover script
• log file for the collector

README contains more informations about the usage.

About the failover script

In the first version, DCS was configured by default on 'api.steemit.com'. I have added a failover script to use another api endpoint (in the config.json)

Failover script function (utils/utils.js)

exports.failover = function() {
if(config.rpc_nodes && config.rpc_nodes.length > 1) {
var cur_node_index = config.rpc_nodes.indexOf(steem.api.options.url) + 1;
if(cur_node_index == config.rpc_nodes.length)
cur_node_index = 0;
var rpc_node = config.rpc_nodes[cur_node_index];
steem.api.setOptions({ transport: 'http', uri: rpc_node, url: rpc_node });
}
}

Plus, api endpoint is randomly selected at startup.

steem.api.setOptions({ transport: 'http', uri: config.rpc_nodes.random(), url: config.rpc_nodes.random() });

Array.prototype.random = function () {
return this[Math.floor((Math.random()*this.length))];
}

code structure

index.js is used for the collector.

app.js is a collection of command that will be used manually by the user to query, add and delete content :

• action/list.js : used to return the content stored
• action/add.js : used to add manually specific content
• action/del.js : used to delete manually specific content

The following script has been declared in the package.json :

• start : start the colletor
• list : list all content
• listAuthor : list all content for the specified author (passed in argument)
• show : Display metadata for the specified pinset (passed in arguent)
• report : Display content in markdown format
• add : Manually add content for the specified dtube url (passed in argument)
• rm : Manuelly remove content for the specified pinset (passed in argument)
