Add more configurable event options about drizzle-legacy HOT 3 CLOSED

#40

from drizzle-legacy.

Hi I think this is merged and the Issue can be closed.

What I am missing though is a simple usage example of configuring the DrizzleStore aswell as getting the event data. it seems to confuse a lot of people.

@soundyogi I am not sure if this question was directed towards this particular merge or just the package in general. Here is an example of passing event options to the configs:

Ex: Contract named Escrow with an event named FundsWithdrawn and FundsAvailableForWithdraw.:

contracts: [
    Escrow
],
events: {
    Escrow: [
        'FundsAvailableForWithdraw',  // listen for 'latest' events
        {
            eventName: 'FundsWithdrawn',
            eventOptions: {
                fromBlock: 0 // ideally contract creation block, but listen for events from block '0' to 'latest'
            }
    ]
}

If you need help reading data from the DrizzleStore you might reference drizzle-react-components.
