x2y-dev-tools-sdk

A high-performance, local-first SDK for API traffic monitoring, predictive issue analysis, and intelligent code refactoring. Designed for heavy-load systems and modern TypeScript/JavaScript development workflows.

Version: 1.0.4 | By: x2y DevTools | Support: [email protected] | Docs: https://sdk.x2ydevs.xyz/

Core Capabilities

1. API Traffic Monitoring

Records and analyzes API calls with detailed metrics including endpoint, method, response time, status code, and headers. Data is stored efficiently in memory for real-time statistical analysis.

2. Predictive Issue Analysis

Anticipates API failures before they occur. The SDK analyzes recorded traffic patterns using Standard Deviation and Coefficient of Variation (CV) to surface risk levels, rate-limit proximity, and suggested fallback endpoints.

3. Intelligent Code Refactoring

Provides line-level suggestions to improve code quality by detecting:

• Idiomatic Patterns: Modernizing var to let/const for block scoping.
• Performance Bottlenecks: Identifying N+1 database queries and DOM thrashing inside loops.
• Async Modernization: Converting legacy .then() chains into clean async/await syntax.

4. Rate Limit Detection

Monitors x-ratelimit-remaining and related headers across every recorded call. The engine predicts when limits will be reached and provides proactive warnings before requests begin failing.

Installation

npm install x2y-dev-tools-sdk

Usage Guide

Initialization

Configure the SDK with specific thresholds and rule sets for your project requirements.

const { X2YSdk } = require('x2y-dev-tools-sdk');

const sdk = new X2YSdk(
  { 
    rateLimitThreshold: 80, // Trigger warning at 80% usage
    predictionWindow: 60000 
  },
  { 
    targetLanguage: 'typescript',
    rules: ['performance', 'idiom', 'async']
  }
);

Live Traffic Monitoring & Prediction

Record real HTTP telemetry and analyze the health of your endpoints using statistical models.

// Record a live API call
sdk.recordAPITraffic({
  endpoint: '/api/users',
  method: 'GET',
  timestamp: Date.now(),
  responseTime: 120,
  statusCode: 200,
  headers: { 'x-ratelimit-remaining': '95' }
});

// Analyze the health of an endpoint
const prediction = await sdk.predictAPIIssues('/api/users');
console.log(prediction);

Expected Output:

{
  "endpoint": "/api/users",
  "riskLevel": "low",
  "predictedFailure": false,
  "rateLimitApproaching": false,
  "suggestedAlternatives": [],
  "confidence": 92
}

Intelligent Code Refactoring

Analyze strings or entire files to detect architectural flaws and modernize legacy syntax.

const legacyCode = `
function getData() {
  var results = [];
  return fetch('/api/data')
    .then(function(res) { return res.json(); });
}
`;

const suggestions = await sdk.refactorCode(legacyCode);
console.log(suggestions);

Expected Output:

[
  {
    "type": "idiom",
    "description": "Use const/let instead of var for block scoping",
    "severity": "medium",
    "line": 2
  },
  {
    "type": "async",
    "description": "Modernize legacy promise chains to async/await syntax",
    "severity": "high",
    "line": 4
  }
]

Live Production Validation

The following results were generated during a final release gate validation against the live GitHub API. This test demonstrates real-world telemetry, controlled concurrency, and dynamic confidence scoring.

Test Configuration

• Environment: Live GitHub API (api.github.com)
• Concurrency: 5 simultaneous requests per batch
• Total Requests: 15
• Rules Enabled: Performance, Idiom, Async

Validation Results

Traffic Metrics:

• Total Requests: 15
• Successful Requests: 15
• Latency Range: 77ms - 1160ms
• Average Latency: 234.8ms

Predictive Analysis Output:

      "confidence": 55
    },
    {
      "endpoint": "/repos/x2ydevs/x2y-sdk",
      "riskLevel": "low",
      "rateLimitApproaching": true,
      "confidence": 52
    }
  ],
  "refactoringAudit": {
    "totalIssues": 3,
    "performanceBottlenecks": 1,
    "asyncModernizations": 1,
    "idiomUpdates": 1
  }
}

Key Observations

1. Dynamic Confidence: Confidence scores varied between 52% and 60% based on the latency jitter and stability of each specific endpoint.
2. Rate Limit Awareness: The SDK correctly identified that the test account was approaching its hourly quota (10/60 remaining).
3. Error Handling: The system successfully captured and analyzed a real 404 error, adjusting the risk level from "low" to "medium" for that specific endpoint.

Architecture

• Local-First Processing: All monitoring and analysis occur within the local Node.js environment to ensure zero external dependencies for core logic.
• Statistical Intelligence: Uses Coefficient of Variation (CV) to differentiate between stable and erratic system behavior.
• TypeScript Native: Built with TypeScript and provides full type definitions for seamless integration into modern build pipelines.
