name: dbc-schema description: Generate Effect Schema definitions for WoW DBC tables. Use when adding new game data tables or updating existing schemas.

DBC Schema Generator

Generate Effect Schema definitions for WoW database tables.

Schema Location

packages/wowlab-core/src/internal/schemas/dbc/

Schema Template

// {TableName}Schema.ts
import * as Schema from "effect/Schema";

export class {TableName} extends Schema.Class<{TableName}>("{TableName}")({
  ID: Schema.Number,
  // Other fields - preserve CSV column order!
  Name: Schema.String,
  Description: Schema.String,
  Flags: Schema.Number,
  // ...
}) {}

export const {TableName}Schema = Schema.Array({TableName});

Important Rules

1. Preserve CSV column order - perfectionist sorting is disabled for DBC schemas
2. Use Schema primitives - Schema.Number, Schema.String, Schema.Boolean
3. Nullable fields - Use Schema.NullOr(Schema.Number) for optional numeric fields
4. Arrays - Use Schema.Array(Schema.Number) for array columns

Column Type Mapping

Registration

After creating schema, register in DbcTableRegistry.ts:

import { {TableName} } from "./internal/schemas/dbc/{TableName}Schema.js";

// Add to registry type
export type DbcTableName =
  | "Spell"
  | "{TableName}"  // Add here
  | ...;

// Add to row type mapping
export type DbcRow<T extends DbcTableName> =
  T extends "{TableName}" ? {TableName} :
  ...;

Instructions

1. Get CSV headers from DBC table
2. Map columns to Schema types
3. Generate schema class (preserve column order!)
4. Register in DbcTableRegistry
5. Re-export from Schemas.ts if public API
