I'm trying to test on Rinkeby so I ran the following command

geth --rpc --rpcaddr localhost --rpcport 8545

Within my Javascript file I have the following code

if (typeof web3 !== 'undefined') {
        window.web3 = new Web3(web3.currentProvider);
        console.log(`Web 3 is: ${web3}`);
    } else {
        console.log('No web3? You should consider trying MetaMask!')
        window.web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
        console.log(window.web3);
    }

However it still logs No web3? You should consider trying MetaMask! What exactly am I doing wrong here? I set Rinkeby to be on localhost 8545.

Here is my Terminal Log

  • If the javascript code you are linking is being ran through a web browser, than you should double check that metamask is installed, and pointing to the rinkeby network. If the javascript code you are linking is being ran on a server, I would opt for connecting to the IPC endpoint. – hextet Dec 22 '17 at 23:10

Try adding the below flags too. I assume web3 part of rpcapi was not loaded with the command that you have run. --rpcapi db,eth,net,web3,personal and --rpccorsdomain "*"

Complete command be like

geth --rinkeby --rpc --rpcapi db,eth,net,web3,personal --cache=2048  --rpcport 8545 --rpcaddr 127.0.0.1 --rpccorsdomain "*"
  • That actually solved it! The question is how to I connect MetaMask to it now? And how do I get the default account? – JorahFriendzone Dec 24 '17 at 1:32
  • There are two things here, 1. if you use metamask, you don't need a local geth node. 2. If you want to connect metamask to your local node, you can click on the Drop down next to the label "main network" from where you can choose localhost 8545. – Rajesh Dec 25 '17 at 15:50
  • If I use metamask how do I connect to it? I've tried doing the if (typeof web3 !== 'undefined') to try and see if I'm connected to Rinkeby, but it always shows that I'm not connected. – JorahFriendzone Dec 26 '17 at 22:26
  • You need to have logged in to metamask and have connected to the rinkeby network in it. You can also import your account into it. – Rajesh Dec 27 '17 at 1:38
