/ˈɡruːpi/, noun (informal)
"A fan following a band's events with the hope of meeting them."
Description: A node.js crawler for following (Ethereum smart contract) events and making them available via LMDB.
Solidity contracts are emitting events as state transition markers for off-chain applications to stay synchronized.
An out-of-band synchronization of a large Ethereum smart contract can be technically challenging. Downloading block event logs can fail, event parsing can be ambiguous and follow-up downloads can complicate the pipeline.
@attestate/groupie is an embeddable process that keeps an ordered record of
specified Ethereum events in a thread-safe LMDB. Developers can spin up groupie
to synchronized to Ethereum's latest state while thread-safely reading the
entries from disk using LMDB.
