ProcessingDataProvider

Runtime data provider for processing skills (cooking, firemaking, smelting, smithing). Builds lookup tables from recipe manifest files loaded by DataManager. Location: packages/shared/src/data/ProcessingDataProvider.ts

Overview

ProcessingDataProvider is a singleton that:

Loads recipe manifests from recipes/ directory
Builds efficient lookup tables for runtime queries
Provides methods to check requirements and availability
Falls back to embedded item data if manifests missing

getSummary(): {
  cookableItems: number;
  burnableLogs: number;
  smeltableBars: number;
  smithingRecipes: number;
  isInitialized: boolean;
}

Example:

const summary = processingDataProvider.getSummary();
console.log(`Loaded ${summary.smithingRecipes} smithing recipes`);

rebuild

Rebuild all lookup tables (for testing or after manifest reload).

rebuild(): void

Performance Optimizations

Pre-Allocated Buffers

ProcessingDataProvider uses pre-allocated buffers to reduce GC pressure:

// Pre-allocated Map for inventory counting
private readonly inventoryCountBuffer = new Map<string, number>();

// Reused across getSmeltableBarsFromInventory and getSmithableItemsFromInventory
private buildInventoryCounts(inventory): Map<string, number> {
  this.inventoryCountBuffer.clear();
  // ... populate buffer
  return this.inventoryCountBuffer;
}

This avoids creating new Map instances on every inventory query.

Manifest Loading

ProcessingDataProvider loads recipes from JSON manifests:

Loading Order

DataManager loads recipe manifests from recipes/ directory
DataManager calls processingDataProvider.loadCookingRecipes(manifest)
DataManager calls processingDataProvider.loadSmeltingRecipes(manifest)
DataManager calls processingDataProvider.loadSmithingRecipes(manifest)
DataManager calls processingDataProvider.rebuild()

Fallback Behavior

If recipe manifests are missing, ProcessingDataProvider falls back to embedded item data:

// Try manifest first
if (this.cookingManifest) {
  this.buildCookingDataFromManifest();
} else {
  // Fallback: scan ITEMS for items with cooking property
  this.buildCookingDataFromItems();
}

This ensures backwards compatibility with older manifest formats.

Usage Examples

Check if Player Can Smelt

const inventory = world.getInventory(playerId);
const smithingLevel = player.skills.smithing.level;

const availableBars = processingDataProvider.getSmeltableBarsFromInventory(
  inventory,
  smithingLevel
);

if (availableBars.length > 0) {
  console.log(`Player can smelt ${availableBars.length} bar types`);
}

Get Smithing UI Data

const inventory = world.getInventory(playerId);
const smithingLevel = player.skills.smithing.level;

const recipes = processingDataProvider.getSmithableItemsWithAvailability(
  inventory,
  smithingLevel
);

// Group by category for UI
const byCategory = new Map();
for (const recipe of recipes) {
  if (!byCategory.has(recipe.category)) {
    byCategory.set(recipe.category, []);
  }
  byCategory.get(recipe.category).push(recipe);
}

// Render UI with greyed-out items
for (const [category, items] of byCategory) {
  console.log(`Category: ${category}`);
  for (const item of items) {
    const available = item.meetsLevel && item.hasBars;
    console.log(`  ${item.name} - ${available ? "Available" : "Locked"}`);
  }
}

Validate Smelting Request

const barItemId = "steel_bar";
const smeltingData = processingDataProvider.getSmeltingData(barItemId);

if (!smeltingData) {
  console.error("Invalid bar type");
  return;
}

if (player.skills.smithing.level < smeltingData.levelRequired) {
  console.error(`Need level ${smeltingData.levelRequired} Smithing`);
  return;
}

// Check materials
const hasIron = inventory.some(i => i.itemId === "iron_ore");
const hasCoal = inventory.filter(i => i.itemId === "coal").length >= 2;

if (!hasIron || !hasCoal) {
  console.error("Missing materials");
  return;
}

// Start smelting
world.emit(EventType.PROCESSING_SMELTING_REQUEST, {
  playerId,
  barItemId,
  furnaceId,
  quantity: 10
});
