Usage

const {
    SlotsChannelHandler,
    SlotsValidator
} = require('dbet-channels-backend')

const Web3 = require('web3')
const {thorify} = require('thorify')

const web3 = thorify(new Web3(), 'http://localhost:8669')

const mongodb = require('mongodb')
const MongoClient = mongodb.MongoClient
const redis = require('ioredis')

const db = await initDb()
const redisClient = await initRedisClient()

// Initialize config variables
const config = {
    privateKey: '',
    channelTx: {
        expiration: 32,
        gas: 1000000,
        nonce: 11111111
    }
}

const slotsChannelHandler = new SlotsChannelHandler({

    db,
    redisClient,
    config
})
const slotsValidator = new SlotsValidator({

})

try {
    slotsChannelHandler.watchEvents()
    slotsChannelHandler.watchPastEvents()
    slotsChannelHandler.watchExpiredChannels()
    
    await slotsValidator.initChannel(data)

        address
    )
} catch (e) {
    console.error(`Received error: ${e.message}, ${e.stack}`)
}
