How to use (In NodeJS)

(Requires a MongoDB to be installed on the local machine)

    this.tinyFox = new TinyFox()
    await this.tinyFox.init({suffix: 'development'})



    let tinyfoxConfig = {
        contractType: 'ERC20',
        contractAddress: '0xab89a7742cb10e7bce98540fd05c7d731839cf9f' ,
        startBlock: 1316824,
        
        courseBlockGap: 1000, 
        fineBlockGap: 50,
        indexRate: 10000,
        updateBlockNumberRate:60000
    } 

    this.tinyFox.startIndexing( this.web3, tinyfoxConfig )  
    
    this.tinyFox.stopIndexing()   
    
    this.tinyFox.resetState()  
    
    
    

As tinyfox indexes, it starts at 'startBlock' and is collecting events at a pace of 'courseBlockGap' blocks read per 'indexRate' of time.
It stores these events inside of a mongo database named 'tinyfox_{{suffix}}' and inside of a collection named 'event_data'

Once tinyfox synchronizes to the front of the blockchain data (current state) then it will use the 'fineBlockGap' to remain synchronized.

As tinyfox is scraping chaindata for the ERC20/ERC721 token, it is also building a cache of user balances in the tables named 'erc20_balances' and 'erc721_balances'.
