# or
pnpm add cs2inspects
# or
yarn add cs2inspects

Quick Start

Single Item Inspection

import { inspect } from "cs2inspects";

// Using Steam inspect URL
const result = await inspect(
  "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198023809011A40368145941D14586214085613790969"
);

// Using individual parameters
import { inspectFromParameters } from "cs2inspects";

const result = await inspectFromParameters({
  s: "76561198023809011", // Steam ID
  a: "40368145941", // Asset ID
  d: "14586214085613790969", // Definition ID
  m: "0", // Market ID (optional)
});

console.log(result);

Bulk Item Inspection

import { bulkInspect } from 'cs2inspects';

// Background processing (default)
const backgroundResult = await bulkInspect({
  items: [
          {
        s: "76561198023809011",
        a: "40368145941",
        d: "14586214085613790969",
        m: "0"
      },
      {
        url: "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198023809011A40368145942D14586214085613790970"
      }
  ],
  waitForAll: false, // Process in background
  lowPriority: false
});

// Wait for all results
const completeResult = await bulkInspect({
  items: [...],
  waitForAll: true // Wait for all inspections to complete
});

  password?: string; // Authentication password (optional)
}

BulkInspectItem Interface:

interface BulkInspectItem {
  s?: string; // Steam ID
  a?: string; // Asset ID
  d?: string; // Definition ID
  m?: string; // Market ID
  url?: string; // Full Steam inspect URL (alternative to s,a,d,m)

Utility Functions

validateInspectUrl(url: string): { valid: boolean; error?: string }

Validates a Steam inspect URL format.

parseInspectUrl(url: string): InspectParameters | null

createInspectUrl(s: string, a: string, d: string, m?: string): string

Creates a Steam inspect URL from individual parameters.

Statistics and Monitoring

getSimpleStats(): SimpleStats

Returns basic service statistics.

getServiceStats(): ServiceStats

Returns detailed service statistics including queue and worker information.

getQueueStats(): QueueStats

Returns queue-specific statistics.

Worker Management

workerManager.init(): Promise<void>

Initializes the worker system (if enabled).

workerManager.getActiveWorkerCount(): number

Returns the number of active workers.

workerManager.shutdown(): Promise<void>

Shuts down all workers gracefully.

Configuration

Environment Variables

• WORKER_ENABLED - Enable multi-threaded workers (default: false)
• MAX_WORKERS - Maximum number of worker threads (default: 4)
• QUEUE_TIMEOUT - Queue timeout in milliseconds (default: 10000)
• MAX_QUEUE_SIZE - Maximum queue size (default: 100)

Example Configuration

# Enable workers with 8 threads
WORKER_ENABLED=true
MAX_WORKERS=8

# Increase queue limits
QUEUE_TIMEOUT=30000
MAX_QUEUE_SIZE=200

Examples

Basic Usage

import { inspect, bulkInspect } from "cs2inspects";

// Single inspection
const singleResult = await inspect("steam://rungame/730/...");

// Bulk inspection
const bulkResult = await bulkInspect({
  items: [{ s: "123", a: "456", d: "789" }, { url: "steam://rungame/730/..." }],
  waitForAll: true,
});

Performance Testing

import { bulkInspect, getSimpleStats } from "cs2inspects";

// Process 50 items
const items = Array.from({ length: 50 }, (_, i) => ({
  s: "76561198023809011",
  a: (40368145941 + i).toString(),
  d: "14586214085613790969",
}));

const startTime = Date.now();
const result = await bulkInspect({ items, waitForAll: true });
const duration = Date.now() - startTime;

console.log(`Processed ${result.total} items in ${duration}ms`);
console.log("Stats:", getSimpleStats());

Error Handling

import { inspect, InspectError } from "cs2inspects";

try {
  const result = await inspect("invalid-url");

  if ("error" in result) {
    const error = result as InspectError;
    console.error(
      `Inspection failed: ${error.error} (Status: ${error.status})`
    );
  } else {
    console.log("Success:", result.iteminfo);
  }
} catch (error) {
  console.error("Unexpected error:", error);
}

Error Codes

| Status | Description | | ------ | -------------------------------- | | 200 | Success | | 400 | Bad Request - Invalid parameters | | 503 | Service Unavailable | | 504 | Gateway Timeout | | 500 | Internal Server Error |

Performance Considerations

• Bulk Processing: Use waitForAll: false for better throughput when you don't need immediate results
• Priority Queuing: Use lowPriority: true for non-urgent requests
• Worker Threads: Enable workers for CPU-intensive operations
• Queue Management: Monitor queue size to prevent memory issues

TypeScript Support

This package includes full TypeScript definitions. All interfaces and types are exported:

import {
  InspectResponse,
  InspectError,
  BulkInspectRequest,
  BulkInspectResponse,
  ServiceStats,
} from "cs2inspects";
