A simple module for handling Ethereum RPC filters that require watching.
npm install --save ethjs-filter
const HttpProvider = ;const Eth = ;const EthFilter = ;const eth = '';const filters = eth;const filter = delay: 300;filter;filter;const filter =filter;filter;const filter =;const watcher = filter;watcher;filter;
A simple module to help manage Ethereum RPC filters that supports both callbacks and promises.
.watch promises only fire once (as Promise standards specify), and will only fire when the watcher result has a length greater than zero (i.e. logs are present).
