This is a simple visualization project for my ApolloChain demo/prototype.
It is based on web3.js and communicates directly with the local Ethereum node running on your machine. You should run your node with parameters like those:
geth --networkid 42 --nodiscover --rpc --rpccorsdomain "*" console
In order to allow the browser to communicate with the RPC API.
To build the project, run:
browserify viz.js -o main.js
You need to change the
account variable to your account address, and
contractAddress to the address of the ApolloTrade smart contract deployed on your blockchain.
If your Ethereum client's RPC port is different than the default, change the following line:
var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
abi.js contains the ABI for the smart contract.
The web3 API is used to display some information about the account:
ApolloTrade smart contract functions are called to display specific information:
Then a filter is set up to scan all new blocks for transactions and display their contents.
findFunctionByHash() are used to decode the function hash found in the
input parameter for the transaction. Then, web3's
SolidityCoder internal class is used to decode the parameters for the function. This allows us to display the details of the ApolloTrade smart contract functions.
