A proof of concept of a frontend-only block explorer for ganache.
See live demo at https://ganache-explorer-poc.fvictorio.now.sh/
Go to the configuration tab and set the RPC URL of your local instance (http://localhost:8545 is used by default).
You can also add known ABIs. When a transaction is inspected, all events that belong to a known ABI will be properly parsed.
There's a sort of "address book" where you can associate names to addresses. These names show up in the "From" and "To" fields of the transaction. (It would be nice to also show them in the parsed events data).
Add a custom network in MetaMask and use https://ganache-explorer-poc.fvictorio.now.sh/# as the explorer (the trailing # is important!). That way you can open transactions in the explorer directly from MetaMask.
For this to work, you need to use an RPC URL different from http://localhost:8545, because that URL comes by default with MetaMask and cannot be edited. You can start ganache in another port by doing ganache-cli -p 8555.
