Stake Engine Client

Lightweight TypeScript client extracted from Stake Engine web-sdk for RGS (Remote Gaming Server) API communication. Contains only essential backend communication code without Svelte dependencies or slot game scripts.

Features

• 🚀 Lightweight: Only essential RGS communication code
• 📱 Framework Agnostic: Works with any JavaScript framework
• 🔒 Type Safe: Full TypeScript support with auto-generated types
• 🎯 Simple API: High-level methods for common operations
• 🔧 Configurable: Low-level access for custom implementations
• 💰 Smart Conversion: Automatic amount conversion between formats

Installation

npm install stake-engine-client

Quick Start

import { requestAuthenticate, requestBet } from 'stake-engine-client';

// Authenticate player
const auth = await requestAuthenticate({
  sessionID: 'player-session-123',
  rgsUrl: 'api.stakeengine.com',
  language: 'en'
});

console.log('Player balance:', auth.balance?.amount);
console.log('Available bet levels:', auth.config?.betLevels);

// Place a bet
const bet = await requestBet({
  sessionID: 'player-session-123',
  currency: 'USD',
  amount: 1.00, // $1.00 (automatically converted)
  mode: 'base',
  rgsUrl: 'api.stakeengine.com'
});

console.log('Round ID:', bet.round?.roundID);
console.log('Payout multiplier:', bet.round?.payoutMultiplier);

API Reference

Authentication

requestAuthenticate(options)

Authenticate a player session with the RGS.

const auth = await requestAuthenticate({
  sessionID: string,
  rgsUrl: string,
  language: string
});

Returns: AuthenticateResponse

• balance - Player's current balance
• config - Game configuration including bet levels
• round - Active round information (if any)
• status - Operation status

Betting

requestBet(options)

Place a bet and start a new round.

const bet = await requestBet({
  sessionID: string,
  currency: string,
  amount: number,      // Dollar amount (e.g., 1.00 for $1)
  mode: string,        // Bet mode (e.g., 'base')
  rgsUrl: string
});

Returns: PlayResponse

• round - Round details including payout and multiplier
• balance - Updated player balance
• status - Operation status

requestEndRound(options)

End the current betting round.

const result = await requestEndRound({
  sessionID: string,
  rgsUrl: string
});

Balance Management

requestBalance(options)

Get current player balance.

const balance = await requestBalance({
  sessionID: string,
  rgsUrl: string
});

Game Events

requestEndEvent(options)

Track a game event for bet progress.

const result = await requestEndEvent({
  sessionID: string,
  eventIndex: number,
  rgsUrl: string
});

Testing & Debugging

requestForceResult(options)

Search for specific game results (useful for testing).

const results = await requestForceResult({
  mode: string,
  search: {
    bookID?: number,
    kind?: number,
    symbol?: string,
    hasWild?: boolean,
    wildMult?: number,
    gameType?: string
  },
  rgsUrl: string
});

Advanced Usage

Custom Client Instance

import { StakeEngineClient } from 'stake-engine-client';

const client = new StakeEngineClient();

// Make custom API calls with full type safety
const response = await client.post({
  url: '/wallet/authenticate',
  rgsUrl: 'api.stakeengine.com',
  variables: {
    sessionID: 'player-123',
    language: 'en'
  }
});

Low-level HTTP Client

import { fetcher } from 'stake-engine-client';

const response = await fetcher({
  method: 'POST',
  endpoint: 'https://api.stakeengine.com/wallet/play',
  variables: { sessionID: 'abc123', amount: 1000000 }
});

const data = await response.json();

Amount Conversion

The client automatically handles amount conversion between different formats:

import { API_AMOUNT_MULTIPLIER, BOOK_AMOUNT_MULTIPLIER } from 'stake-engine-client';

// API format: 1,000,000 = $1.00
const apiAmount = 1.00 * API_AMOUNT_MULTIPLIER; // 1000000

// Book format: 100 = $1.00  
const bookAmount = 1.00 * BOOK_AMOUNT_MULTIPLIER; // 100

Type Definitions

The package includes comprehensive TypeScript definitions:

import type {
  StatusCode,
  BalanceObject,
  RoundDetailObject,
  ConfigObject,
  AuthenticateResponse,
  PlayResponse,
  BetType,
  BaseBetType
} from 'stake-engine-client';

Status Codes

The RGS API returns standard status codes:

• SUCCESS - Operation completed successfully
• ERR_IPB - Insufficient player balance
• ERR_IS - Invalid session token/timeout
• ERR_ATE - Authentication failed/expired
• ERR_GLE - Gambling limits exceeded
• ERR_BNF - Bet not found
• ERR_UE - Unknown server error
• And more...

Bet Types

For game-specific betting logic:

interface MyGameEvent {
  symbol: string;
  multiplier: number;
  position: [number, number];
}

type MyGameBet = BetType<MyGameEvent>;

// Use in your game logic
const processBet = (bet: MyGameBet) => {
  bet.state.forEach(event => {
    console.log(`Symbol ${event.symbol} at ${event.position}`);
  });
};

Error Handling

All methods return responses with status information:

const bet = await requestBet({
  sessionID: 'player-123',
  currency: 'USD',
  amount: 1.00,
  mode: 'base',
  rgsUrl: 'api.stakeengine.com'
});

if (bet.status?.statusCode === 'SUCCESS') {
  // Handle successful bet
  console.log('Bet placed successfully!');
} else if (bet.status?.statusCode === 'ERR_IPB') {
  // Handle insufficient balance
  console.log('Insufficient balance');
} else {
  // Handle other errors
  console.log('Error:', bet.status?.statusMessage);
}

Package Extraction
