Storacle - decentralized file storage

image


Before I begin, I must leave a link to the previous article , so that it is clear what exactly is meant.


In this article, I would like to parse the layer that is responsible for storing files, and how it can be used by anyone. Storacle is an independent library , there is no direct connection with music. You can organize the storage of any files.


In the previous article, I rolled the barrel a bit on ipfs , but this happened precisely in the context of the problem I was solving . In general, I think this project is cool. I just like the opportunity to create different networks for different tasks. This allows you to better organize the structure and reduce the load on individual nodes and the network as a whole. It is possible even within the framework of one project, if necessary, to break the network into pieces according to some criteria, reducing the overall load.


So, storacle uses a spreadable mechanism for networking. Key Features:


  • Files can be added to the repository through any node.
  • Files are saved in their entirety, not in blocks.
  • Each file has its own unique hash on the contents for further work with it.
  • Files can be duplicated for greater reliability.

const  Node = require('storacle').Node;

(async () => {
  try {
    const node = new Node({
      port: 4000,
      hostname: 'localhost'
    });
    await node.init();
  }
  catch(err) {
    console.error(err.stack);
    process.exit(1);
  }
})();

:


const  Client = require('storacle').Client;

(async () => {
  try {
    const client = new  Client({
      address: 'localhost:4000'
    });
    await client.init();
    const hash = await client.storeFile('./my-file');
    const link = await client.getFileLink(hash); 
    await client.removeFile(hash);
  }
  catch(err) {
    console.error(err.stack);
    process.exit(1);
  }
})();
