Run Public Site Without Exposing 8545

What would need to be changed in the settings or the code to make the app handle its RPC calls internally and now expost them to the WebUI?

I want to run this as a public blockchain explorer but don't want to expose my RPC port publicly. (I assume that rpccors is supposed to protect it but that seems like a small barrier).

Can't seem to get it to work

It always says that i have to execute geth with
geth --rpc --rpccorsdomain "http://localhost:8000"
My geth node is fully synced and up to date.
Found this link to a demo somewhere, it seems to not work aswell.
http://whitjack.me/explorer

How to run it on mobile browser?

npm install doesn't work.

For me npm start fails on:
404 Not Found: natives@^1.1.0.

[BOUNTY] Improved Installation Instructions

Part of group #2

We need better documentation on how to get the explorer up and running including Geth setup, NPM/bower, and using the application

Cannot connect to chain on port other than 8545

Hi all

Although I've changed the app.js configuraton file to my IP address and RPC port running the private Ethereum I still cannot see blockcs/transactions.

Can you help?

Regards,

What version of nodejs and npm should you be using for this to operate/work/function?

I'm currently running the new version of geth w/ POA instead of PoW. I've tried installing the new nodejsv10.7 and also tried running it with v8.1.3... both of them didn't work. The 8.1.3 compiled and ran but the block explorer remained empty and wouldn't display blocks nor balances in wallets. I'm wondering whats the proper version to get this working.

Errors while installing. geth -rpc -rpccorsdomain "http://localhost:8000"

Found some troubles with installation. After following instructions up to "npm start" got errors in console and message geth -rpc -rpccorsdomain "http://localhost:8000" in browser.

To solve this issue you need to install g++ (sudo apt install g++), then run npm audit fix --force.

Now npm start will start correctly.

Error message not going away

I want to use this explorer at my private dev network. However, I'm not able to get rid of the error message

geth --rpc --rpccorsdomain "http://localhost:8000"

Do I have any geth argument which might prevent this explorer to connect?

./geth --identity "DevNode" --genesis ~/git/eth/dev/custom_genesis.json --rpc --rpcport "8102" --rpccorsdomain "http://localhost:8000" --datadir "~/git/eth/data/" --port "30301" --nodiscover --ipcapi "admin,db,eth,debug,miner,net,shh,txpool,personal,web3" --rpcapi "db,eth,net,web3" --autodag --networkid 7682878 --nat "any" --dev --ipcpath "~/.ethereum/geth.ipc" --mine --minerthreads=1 --unlock 0x69B7900537449e862c19aAF1D08b648e76629EBa console

Add AddressInfo?

Any ideas on how to add AddressInfo in? This is what I have so far:

angular.module('ethExplorer')
    .controller('addressInfosCtrl', function ($rootScope, $scope, $location) {

        $scope.init=function()
        {


            $scope.addressId=$routeParams.addressId;

            if($scope.addressId!==undefined) {
                getAddressInfos()
                    .then(function(result) {
                        var wallet = web3.fromWei(eth.getBalance("addressId"), "ether");
                        $scope.result = result;

                    })

            }
        }

    });

How to create prod build

Can you please add script to create prod build so that it can be deployed in any domain?

Add transaction trace page

This is a feature request for adding the transaction trace page similar to Etherscan's transaction trace https://rinkeby.etherscan.io/vmtrace?txhash=0x2e77009bda0fc9c07a01a4589d9b426382521c6e04b84008ffda637a4268824f

The page should show Step, PC, Operation, Gas, GasCost, Depth, optionally memory, stack, and storage.

debug_tracetransaction can be used to get the traces https://ethereum.stackexchange.com/questions/9434/calling-debug-tracetransaction-from-web3-api

Private blockchain?

Hello,
Does this explorer run on private ethereum networks?
I tried to run it but i cannot see any tx,address on it (blank page)

Welcome to use my explorer: http://eth.luchenqun.com/

can I use to allow anyone explore my own testnet chain?

Maybe I'm misunderstanding something, but it seems that opening the RPC to all the internet is not such a good idea... can I use etherparty to allow anyone to browse my own testnet? Or do I need a different software for that...?

Error: Allow Access to Geth and Refresh the Page

The server starts and is viewable at port 8000, but there is an error message saying:

Allow Access to Geth and Refresh the Page

I have tried several invocations of geth, including this one:

geth --dev --datadir "<path/to/dir>" --networkid --rpc --rpcaddr localhost --rpcport 8545 --rpcapi "web3,eth" --rpccorsdomain "http://localhost:8000"

I am fairly new to ethereum so this might simply be a silly user error. But regardless, it's still a "bug" in that the error message isn't specific enough to debug. What form of "access" is missing, specifically.

Note that I can see geth at port 8545.

list (latest) transactions/blocks

Hello,

any plans to list the latest transactions/blocks on the home page (for example) ?

Regards,

does not work with the version v1.10.17 of geth

geth --rpc --rpccorsdomain "http://localhost:8000" does not work in version v1.10.17 (geth) which I must replace to make it work with --http --http.api 'web3,eth,net,debug,personal' --http.corsdomain '*'

tx display issue

Hi,

Thanks for creating the explorer, it's very useful while working with testrpc. I haven't found any competitors to this package.

Want to point to the minor bug we have, whenever I want to search for the transaction, for example:
0x1bb91a7f0c59d4a0f1193bb8cb7bf0b3d9aabe147c075367986165545052b3f8

I put it to the search field, but the 0x part of the transaction is cut out and nothing is shown.

However, in case I place full transaction hash in the url, the explorer would successfully find it:

Would be very cool if you apply a fix for that :)

Regards,

Etherparty Explorer deployed on IPFS

I have deployed the explorer for mainnet on IPFS. IPFS and Infura are used for web hosting and RPC connection respectively. Have a look.
/ipfs/QmS8y5dZ7ugdDfiU2GmrjBRzbfcTBQMdA2bhUt4rPrvX4Q/

Implement lazy loading

If the explorer is communicating with a remote node, it can take a really long time for the front page to load as there are multiple requests for each block.

It would be really great if the page was populated as the data came in instead of waiting for all of it.

Make Blocks display realtime

I am interested in this project. Can we make blocks display real time. For example if new blocks is created in blockchain, it gets pushed on top. How can use socket or any such thing here. I was making same project myself and I am facing with this challenge. Any suggestions will be greatly apriciated.

What can I do in order to move forward?

Explorer not loading properly/showing blockchain

Running on Linux, with Firefox.

I'm currently syncing, ran npm start, open web page to "localhost:8000" and this is what it shows. It just got done syncing block #2469264. Searching for that block or any previous block returns the same empty page.

Page http://localhost:8000 did not loaded on browser

I installed everything as per the readme and everything went fine!

http-server ./app -a localhost -p 8000 -c-1
Starting up http-server, serving ./app on port: 8000
Hit CTRL-C to stop the server

But the http://localhost:8000 did not come up. I have local geth running on http://localhost:8545

Anything missing? Kindly suggest!

How can I use the explorer if geth is inside a container?

I'm trying to use the explorer for a geth light node behind a container. I try to add the --rpccorsdomain "http://0.0.0.0:8000" param to the entrypoint of the container, but how can this have an effect on the host side of the container?

Information about peers

Is there a way we can extend this code to show the details of the peers that we are having in our private network

What should i do if i want to watch this page from other computers in a same local area network

sorry ,my English is not good.
I changed "localhost" to "0.0.0.0" in the file explorer/package.json
and change ' --rpccorsdomain "localhost:8000" ' to '--rpccorsdomain "http://192.168.1.105:8000"'.
"192.168.1.105" is ip of the computer which running geth
When i input "192.168.1.105:8000" on the computer which running geth , it is done,
but if i input "192.168.1.105:8000" on another ,it return "allow access to geth and refresh the page"
so , what should i do if i want successful watch this page from other computers?

Does it only run in google chrome ? I've try run it in firefox , ie and safari ,none of them work

The explorer cannot be deployed at AWS.

The explorer works fine in my local machine. However, the explorer cannot work in my AWS machine.
The IP address of AWS machine is 10.10.78.X, but the machine's public IP is 52.40.25.X. It seems due to some "IP:port forwarding mechanism" I think. Is it possible to run the explorer in AWS machine? How? Thanks.

Still getting "Allow Access to Geth and Refresh the Page"

even if --rpccorsdomain "http://localhost:8000" is set ....

can't run up with external IP

When trying to install it on a VPS, and expose 0.0.0.0 to external access, geth configuration can't communicate with web server. So it forever it popup message like
"geth --rpc --rpccorsdomain "http://104.198.101.250:8000"

How to configure if it's for public web access? maybe very simple, but I didn't get it through even after changes.
