• Code:

    var Web3 = require('web3');
    var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
    var sender = web3.eth.accounts[0];
    console.log('Sender: ' + sender);

  • Question:

From the above, commands like web3.eth.accounts[0] works fine, however web3.personal.listAccounts; doesn't. Why might that be the case?

    How did you launch geth? It can be that you have missed enabling the personal api from the command line, try adding personal to the --rpcapi something like this geth --rpc --rpcapi eth,web3,net,ssh,db,debug,personal enable serveral apis.

    Note that this can be very unsafe; there is a reason why the personal interface isn't exposed over RPC by default. You can do this more safely over IPC ethereum.stackexchange.com/questions/1413/… Commented Jul 3, 2017 at 19:45
  • oh thanks @TjadenHess this is really important. I'll try out the method in that post there. Would leaving the --rpc in geth --rpc also cause a security risk? or was it just the --rpcapi ...?
