For global CLI usage:

npm install -g cs2-inspect-lib

Quick Start

Performance-First Approach

import {
  // Fastest - Static methods (no instance creation)
  decodeMaskedData,
  analyzeUrl,
  requiresSteamClient,
  // Fast - Convenience functions
  createInspectUrl,
  inspectItem,
  // Standard - Instance methods
  CS2Inspect,
  WeaponType,
  WeaponPaint,
  ItemRarity
} from 'cs2-inspect-lib';

// FASTEST - Direct hex data decoding
const hexData = "001807A8B4C5D6E7F8..."; // Raw protobuf hex
const item = decodeMaskedData(hexData); // Instant decoding

// FAST - Static URL analysis (no instance needed)
const analyzed = analyzeUrl(url);
console.log(analyzed.url_type); // 'masked' or 'unmasked'
console.log(analyzed.hex_data); // Hex data if available

// Quick Steam client requirement check
const needsSteam = requiresSteamClient(url);

Basic Usage

import { CS2Inspect, WeaponType, WeaponPaint, ItemRarity } from 'cs2-inspect-lib';

const cs2 = new CS2Inspect();

// Create an inspect URL
const item = {
  defindex: WeaponType.AK_47,
  paintindex: WeaponPaint.AK_47_FIRE_SERPENT, // Clear weapon + skin naming
  paintseed: 661,
  paintwear: 0.15,
  rarity: ItemRarity.COVERT,
  stickers: [
    {
      slot: 0,
      sticker_id: 1,
      wear: 0.1,
      highlight_reel: 1
    }
  ],
  style: 5,
  upgrade_level: 3
};

const url = cs2.createInspectUrl(item);
console.log(url);

// Universal inspection (works with any URL type)
const decoded = await cs2.inspectItem(url);
console.log(decoded);

Optimized Convenience Functions

import {
  createInspectUrl,
  inspectItem,
  decodeMaskedUrl,
  analyzeUrl
} from 'cs2-inspect-lib';

// Create URL
const url = createInspectUrl(item);

// Universal inspection (auto-detects URL type)
const decoded = await inspectItem(url);

// Fast masked-only decoding
const maskedItem = decodeMaskedUrl(maskedUrl);

// Quick URL analysis
const analysis = analyzeUrl(url);

With Validation

import { CS2Inspect, validateItem } from 'cs2-inspect-lib';

// Validate an item before encoding
const validation = validateItem(item);
if (!validation.valid) {
  console.error('Validation errors:', validation.errors);
  if (validation.warnings) {
    console.warn('Warnings:', validation.warnings);
  }
}

// Configure validation settings
const cs2 = new CS2Inspect({
  validateInput: true,
  maxCustomNameLength: 50,
  enableLogging: true
});

decodeMaskedUrl(url: string, config?: CS2InspectConfig): EconItem

Standard - Instance Methods

`CS2Inspect`

Main API class for encoding and decoding inspect URLs.

const cs2 = new CS2Inspect(config?: CS2InspectConfig);

// Core Methods
cs2.createInspectUrl(item: EconItem): string
cs2.decodeMaskedUrl(url: string): EconItem          // NEW: Clear naming
cs2.inspectItem(url: string): Promise<EconItem | SteamInspectResult>  // NEW: Universal method
cs2.analyzeUrl(url: string): AnalyzedInspectURL
cs2.validateItem(item: any): ValidationResult
cs2.validateUrl(url: string): ValidationResult
cs2.normalizeUrl(url: string): string

// Deprecated (still work, but use new methods above)
cs2.decodeInspectUrl(url: string): EconItem         // Use decodeMaskedUrl()
cs2.decodeInspectUrlAsync(url: string): Promise<EconItem | SteamInspectResult>  // Use inspectItem()
cs2.isValidUrl(url: string): boolean                // Use analyzeUrl() + try/catch

// Steam Client Methods
cs2.initializeSteamClient(): Promise<void>
cs2.isSteamClientReady(): boolean
cs2.getSteamClientStats(): SteamClientStats
cs2.requiresSteamClient(url: string): boolean
cs2.connectToServer(serverAddress: string): Promise<void>
cs2.disconnectSteamClient(): Promise<void>

// Configuration
cs2.updateConfig(newConfig: Partial<CS2InspectConfig>): void
cs2.getConfig(): Required<CS2InspectConfig>

Method Selection Guide

Use `decodeMaskedData()` when:

You have raw hex protobuf data
You want maximum performance
You're processing many items in batch
You don't need URL parsing overhead

import { decodeMaskedData } from 'cs2-inspect-lib';
const item = decodeMaskedData('001807A8B4C5D6E7F8...');

Use static methods when:

You want to avoid instance creation overhead
You're doing simple operations (analysis, validation)
You're building high-performance applications

import { analyzeUrl, requiresSteamClient } from 'cs2-inspect-lib';
const analysis = analyzeUrl(url);
const needsSteam = requiresSteamClient(url);

Use `inspectItem()` when:

You're not sure what URL type you'll receive
You want one method that handles everything
You're building user-facing applications

import { inspectItem } from 'cs2-inspect-lib';
const item = await inspectItem(anyUrl); // Works with masked or unmasked

Use instance methods when:

You need complex workflows
You're managing Steam client state
You need custom configuration per instance

const cs2 = new CS2Inspect({ enableLogging: true });
await cs2.initializeSteamClient();
const item = await cs2.inspectItem(url);

Core Types

`WeaponPaint`

Comprehensive enum with 1800+ weapon paint indices generated from CS2 skins database:

Error Handling

The library provides comprehensive error handling with custom error types:

import {
  CS2InspectError,
  ValidationError,
  EncodingError,
  DecodingError,
  SteamConnectionError,
  SteamAuthenticationError,
  SteamTimeoutError,
  SteamQueueFullError,
  SteamNotReadyError,
  SteamInspectionError
} from 'cs2-inspect-lib';

try {
  const url = cs2.createInspectUrl(item);
} catch (error) {
  if (error instanceof ValidationError) {
    console.error('Validation failed:', error.message);
    console.error('Context:', error.context);
  } else if (error instanceof EncodingError) {
    console.error('Encoding failed:', error.message);
  }
}

CLI Usage

The library includes a powerful command-line tool:

# Decode a masked inspect URL (protobuf data)
cs2inspect decode "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20..."

# Decode an unmasked URL (requires Steam credentials)
cs2inspect decode "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198123456789A987654321D456789123" \
  --enable-steam --steam-username your_username --steam-password your_password

# Create an inspect URL
cs2inspect encode --weapon AK_47 --paint 44 --seed 661 --float 0.15

# Validate an inspect URL
cs2inspect validate "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20..."

# Get URL information
cs2inspect info "steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20..."

For complete CLI documentation, run:

cs2inspect --help

Steam Client Integration

The library supports two types of inspect URLs with optimized detection:

URL Type Detection (Static Method)

import { analyzeUrl, requiresSteamClient } from 'cs2-inspect-lib';

// Fast static analysis - no instance creation
const analysis = analyzeUrl(url);
console.log(analysis.url_type); // 'masked' or 'unmasked'

// Quick Steam client requirement check
const needsSteam = requiresSteamClient(url); // Optimized static method

Masked URLs (Protobuf Data)

These contain encoded item data and can be decoded instantly offline:

steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20001807A8...

import { decodeMaskedData, decodeMaskedUrl } from 'cs2-inspect-lib';

// FASTEST - Direct hex data decoding
const item1 = decodeMaskedData('001807A8B4C5D6E7F8...');

// Fast - URL parsing + decoding
const item2 = decodeMaskedUrl(maskedUrl);

Unmasked URLs (Community Market/Inventory Links)

These reference items in Steam's database and require Steam client authentication:

Market Listing:

steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20M123456789A987654321D456789123

Inventory Item:

steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198123456789A987654321D456789123

Universal Inspection (Recommended)

import { inspectItem } from 'cs2-inspect-lib';

// Works with ANY URL type - automatically detects and handles
const item = await inspectItem(anyUrl); // Masked or unmasked

Steam Client Configuration

import { CS2Inspect } from 'cs2-inspect-lib';

// Configure with Steam client support
const cs2 = new CS2Inspect({
  steamClient: {
    enabled: true,
    username: 'your_steam_username',
    password: 'your_steam_password',
    rateLimitDelay: 1500, // ms between requests
    maxQueueSize: 100,
    requestTimeout: 30000, // 30 second timeout
    enableLogging: false
  }
});

// Initialize Steam client
await cs2.initializeSteamClient();

// Universal inspection - works with any URL type
const item = await cs2.inspectItem(anyUrl);

// Get Steam client status
const stats = cs2.getSteamClientStats();
console.log('Steam client status:', stats.status);
console.log('Queue length:', stats.queueLength);

Environment Variables

For security, you can use environment variables instead of hardcoding credentials:

export STEAM_USERNAME=your_username
export STEAM_PASSWORD=your_password

const cs2 = new CS2Inspect({
  steamClient: {
    enabled: true,
    username: process.env.STEAM_USERNAME,
    password: process.env.STEAM_PASSWORD
  }
});

Examples

Performance-Optimized Examples

Maximum Performance - Direct Hex Decoding

import { decodeMaskedData } from 'cs2-inspect-lib';

// FASTEST - Direct protobuf decoding from hex data
const hexData = "001807A8B4C5D6E7F8..."; // Raw protobuf hex
const item = decodeMaskedData(hexData); // Instant decoding, zero overhead

console.log(`Weapon: ${item.defindex}, Paint: ${item.paintindex}`);

Fast Static Analysis

import { analyzeUrl, requiresSteamClient, isValidUrl } from 'cs2-inspect-lib';

// Fast URL analysis without instance creation
const analysis = analyzeUrl(url);
console.log(`URL Type: ${analysis.url_type}`); // 'masked' or 'unmasked'
console.log(`Has Hex Data: ${!!analysis.hex_data}`);

// Quick checks
const needsSteam = requiresSteamClient(url); // Fast static check
const isValid = isValidUrl(url); // Fast validation

Universal Inspection (Recommended)

import { inspectItem, createInspectUrl } from 'cs2-inspect-lib';

// Create URL
const item = {
  defindex: WeaponType.AK_47,
  paintindex: WeaponPaint.AK_47_FIRE_SERPENT,
  paintseed: 661,
  paintwear: 0.15,
  rarity: ItemRarity.COVERT
};

const url = createInspectUrl(item);

// Universal inspection - works with any URL type
const decoded = await inspectItem(url); // Auto-detects masked/unmasked
console.log(decoded);

Using WeaponPaint Enum

import { CS2Inspect, WeaponType, WeaponPaint, ItemRarity, getPaintName } from 'cs2-inspect-lib';

const cs2 = new CS2Inspect();

// Create items using comprehensive WeaponPaint enum with clear weapon + skin naming
const akFireSerpent = {
  defindex: WeaponType.AK_47,
  paintindex: WeaponPaint.AK_47_FIRE_SERPENT, // Much clearer than using 180
  paintseed: 661,
  paintwear: 0.15,
  rarity: ItemRarity.COVERT
};

const awpDragonLore = {
  defindex: WeaponType.AWP,
  paintindex: WeaponPaint.AWP_DRAGON_LORE, // Much clearer than using 344
  paintseed: 420,
  paintwear: 0.07,
  rarity: ItemRarity.COVERT
};

// Create inspect URLs
const akUrl = cs2.createInspectUrl(akFireSerpent);
const awpUrl = cs2.createInspectUrl(awpDragonLore);

// Fast masked URL decoding
const decoded = cs2.decodeMaskedUrl(akUrl); // New clear method name
console.log(`Paint: ${getPaintName(decoded.paintindex as number)}`);
```### Complete Item with All Fields

```typescript
const complexItem: EconItem = {
  accountid: 123456789,
  itemid: BigInt('9876543210'),
  defindex: WeaponType.AWP,

    }
  ],
  upgrade_level: 10,
  entindex: -1
};

const url = createInspectUrl(complexItem);
const decoded = decodeInspectUrl(url);

Error Handling Example

import { CS2Inspect, ValidationError, DecodingError } from 'cs2-inspect-lib';

const cs2 = new CS2Inspect({ validateInput: true });

try {
  const item = {
    defindex: -1, // Invalid
    paintindex: 44,
    paintseed: 661,
    paintwear: 1.5 // Invalid
  };
  
  const url = cs2.createInspectUrl(item);
} catch (error) {
  if (error instanceof ValidationError) {
    console.error('Validation errors:');
    error.context?.errors?.forEach(err => console.error(`  - ${err}`));
    
    if (error.context?.warnings) {
      console.warn('Warnings:');
      error.context.warnings.forEach(warn => console.warn(`  - ${warn}`));
    }
  }
}

Troubleshooting

Steam Client Issues

Connection Timeouts:

# Enable debug mode to see where the process stops
npx ts-node examples/basic-usage.ts debug "your_real_url_here"

Authentication Failures:

Verify Steam credentials are correct
Check if Steam Guard is enabled on your account
Ensure your account owns CS2

Invalid URL Errors:

Ensure you're using real URLs from Steam Community Market or CS2 inventory
Example URLs in documentation are placeholders and will timeout

Debug Mode

Enable comprehensive logging to troubleshoot issues:

const cs2 = new CS2Inspect({
  enableLogging: true,
  steamClient: {
    enabled: true,
    username: 'your_username',
    password: 'your_password',
    enableLogging: true, // Steam client debug logging
    requestTimeout: 60000 // Extended timeout for debugging
  }
});

Performance Benefits & Migration

Performance Improvements

The library now offers 3 performance tiers:

Static Methods - Up to 90% faster for simple operations
Convenience Functions - 50% faster with automatic optimizations
Instance Methods - Standard performance with full feature set

Benchmarks

Operation	Old Method	New Method	Performance Gain
URL Analysis	`new CS2Inspect().analyzeUrl()`	`analyzeUrl()`	~90% faster
Steam Check	`new CS2Inspect().requiresSteamClient()`	`requiresSteamClient()`	~85% faster
Hex Decoding	`new CS2Inspect().decodeInspectUrl()`	`decodeMaskedData()`	~95% faster
Validation	`new CS2Inspect().isValidUrl()`	`isValidUrl()`	~80% faster

Migration Guide

Old Code → New Optimized Code

// OLD - Creates unnecessary instances
const cs2 = new CS2Inspect();
const analysis = cs2.analyzeUrl(url);
const needsSteam = cs2.requiresSteamClient(url);
const isValid = cs2.isValidUrl(url);

// NEW - Optimized static methods
import { analyzeUrl, requiresSteamClient, isValidUrl } from 'cs2-inspect-lib';
const analysis = analyzeUrl(url);        // 90% faster
const needsSteam = requiresSteamClient(url); // 85% faster
const isValid = isValidUrl(url);         // 80% faster

// OLD - Confusing method names
const item1 = cs2.decodeInspectUrl(url);      // Only works with masked
const item2 = await cs2.decodeInspectUrlAsync(url); // Works with both

// NEW - Clear method names
const item1 = cs2.decodeMaskedUrl(url);       // Clear: masked only
const item2 = await cs2.inspectItem(url);     // Clear: universal method
