开源软件介绍：

This package:

• Exports a global class named IpfsConnector available only on server
• Downloads ipfs binaries
• Can start ipfs process
• Can send commands to ipfs api server

Example

• On server side create a global variable just before Meteor.startup:

   // for global access on server side
   ipfsObj = false;
  
   const testIpfs = function () {
     // start ipfs daemon
     let started = ipfsObj.start();
     // wait for process to start
     if (started) {
       // test api calls https://www.npmjs.com/package/ipfs-api
       ipfsObj.api.add(new Buffer('random stuff'), (err, data)=> {
         console.log('ipfs hash ' + data[0].Hash);
       });
     }
   };
  
   Meteor.startup(function () {
     ipfsObj          =  IpfsConnector.getInstance(); //singleton
     ipfsObj.setLogLevel('info'); // info is default
     testIpfs();
   });

• Available IpfsConnector methods:

start(); // start ipfs daemon
stop();
setLogLevel('*'); // one of ['trace', 'fine', 'debug', 'info', 'warn', 'error']
api.*; // access ipfs-api https://www.npmjs.com/package/ipfs-api

• Server methods for client

Meteor.call('ipfsCat', ipfsHash, function(err,resp){ ... // get contents from ipfs hash

Meteor.call('ipfsAdd', string or Uint8Array, function(err,resp){ ... // upload contents to ipfs

• FileReader example

    let reader = new FileReader();
    reader.onload = function(){
      let arrayBuffer = new Uint8Array(reader.result);

      Meteor.call("ipfsAdd", arrayBuffer, function(err, result){console.log("ipfs hash ",result);});
    };
    reader.readAsArrayBuffer('inputFileField'[0]);
