Installation

``bash npm install @neural-trader/backend`

The package will automatically install the correct platform-specific binary for your system.

`Usage`

`javascript const backend = require('@neural-trader/backend');

// Example: Calculate technical indicators const prices = [100, 102, 101, 103, 105, 104, 106]; const indicators = backend.calculateTechnicalIndicators(prices);

console.log('Indicators:', indicators);

// Example: Run backtest const strategy = { type: 'momentum', params: { shortPeriod: 10, longPeriod: 20 } };

const backtestResults = backend.runBacktest(strategy, prices); console.log('Backtest results:', backtestResults);`

`Building from Source`

If pre-built binaries are not available for your platform:

`bash

`Clone the repository`


git clone https://github.com/ruvnet/neural-trader.git
cd neural-trader/neural-trader-rust/packages/neural-trader-backend
Install dependencies

npm install
Build for your platform

npm run build
Run tests

npm test


Security
$3
Before running this package, you MUST configure these security-critical environment variables:

#### 1. JWT_SECRET (REQUIRED)`bash

`Generate a secure 64-byte secret`


openssl rand -hex 64
Set in your environment

export JWT_SECRET="your-generated-secret-here"


⚠️ CRITICAL: The application will refuse to start if JWT_SECRET is not set. Never use default or weak secrets in production.

#### 2. API Key Management`bash

`API keys should be generated with high entropy`


export API_KEY_MASTER="your-secure-master-key"


$3
This package includes multiple layers of security:
- Authentication & Authorization
  - JWT token-based authentication
  - Role-Based Access Control (RBAC)
  - API key validation with expiration
  - Session management
- Input Validation
  - SQL injection prevention
  - XSS sanitization
  - Path traversal prevention
  - Comprehensive input sanitization
- Rate Limiting
  - Token bucket algorithm
  - Per-API-key rate limiting
  - DDoS protection
  - Configurable limits
- Audit Logging
  - All security events logged
  - Failed authentication attempts tracked
  - API access audited
$3

1. Always use HTTPS in production 2. Rotate secrets regularly (JWT_SECRET, API keys) 3. Use parameterized queries - never concatenate SQL 4. Enable rate limiting for all public endpoints 5. Monitor audit logs for suspicious activity 6. Keep dependencies updated - runnpm audit` regularly
