Decent.bet channels backend module

Module used to manage state channels on the backend for slots running on the Decent.bet platform.

Requirements

• node.js
• redis
• mongodb
• Running Vechain Thor node

Prerequisites

To run the games API you will need to have the following setup

• A running redis instance
• A running MongoDB instance
• A running Vechain Thor node

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({
    web3,
    db,
    redisClient,
    config
})
const slotsValidator = new SlotsValidator({
    web3,
    db,
    config
})

try {
    slotsChannelHandler.watchEvents()
    slotsChannelHandler.watchPastEvents()
    slotsChannelHandler.watchExpiredChannels()
    
    await slotsValidator.initChannel(data)
    await slotsHandler.initChannel(
        initialDeposit,
        channelNonce,
        initialUserNumber,
        finalUserHash,
        userTxs,
        blockRef,
        blockNumber,
        address
    )
} catch (e) {
    console.error(`Received error: ${e.message}, ${e.stack}`)
}

Tests

Deploy test contracts to testnet and copy contract JSONs to ./build/contracts. To run tests run npm test. For module specific tests:

• npm run test-slots-channel-handler for SlotsChannelHandler
• npm run test-slots-validator for SlotsValidator
