Web3 demo code for Swarm

swarmdemo.js

//
// Needs web3.js from https://github.com/axic/web3.js/tree/swarm
//

var Web3 = require('web3')
var url = require('url')

var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'))
try {
  web3.eth.defaultAccount = web3.eth.coinbase
} catch (e) {
}

var swarmPut = function (buf, enc, cb) {
  web3.bzz.put(buf, enc, function (err, ret) {
    if (err) {
      return cb(err)
    }
    cb(null, ret)
  })
}

var swarmGet = function (key, cb) {
  web3.bzz.get('bzz://' + key, function (err, ret) {
    if (err) {
      return cb(err)
    }
    cb(null, ret.content)
  })
}

swarmPut('Hello World', 'application/text', function (err, ret) {
  if (err) {
    console.log('Swarm put failed: ', err)
    return
  }
  console.log('Added to swarm: ', ret)
  
  swarmGet(ret, function (err, ret) {
    if (err) {
      console.log('Swarm get failed: ', err)
      return
    }
    console.log('Retrieved from swarm: ', ret)
  })
})

Should have an output similar to:

$ node sampleswarm.js
