How do I get web3 currentProvider HTTP URL? I'm using web3 1.0.0-beta.34. I tried many functions and already looked at the docs - but still couldn't find the right way to get the URL of the current HTTP RPC node.

The pseudocode that I'm looking for:

if (is_using_http_rpc_fn) {
  return currentProvider.url;
}

What functions to call for is_using_http_rpc_fn and currentProvider.url in above pseudocode?

  • I looked for an answer myself, but I don't think that it is possible. When you connect to e.g. ropsten using MetaMask, MetaMask will connect to a URL like https://ropsten.infura.io/TOKEN, where TOKEN is unique for the MetaMask application. If you could read out the URL, you'd get the private token, which is why I think that there are security reasons for why this it not possible. What you can do is call web3.version.getNetwork(result => console.log(result)) to see the Network version – Peter Aug 13 '18 at 16:42

I think you can simply use:

web3.currentProvider.connection._url

Confirmed this works for web3 1.0.0-beta36.
