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

Preserve CSV column order - perfectionist sorting is disabled for DBC schemas

Use Schema primitives -

Schema.Number

Schema.String

Schema.Boolean

Nullable fields - Use
```
Schema.NullOr(Schema.Number)
```
for optional numeric fields
Arrays - Use
```
Schema.Array(Schema.Number)
```
for array columns

Column Type Mapping

CSV Type	Effect Schema
int	`Schema.Number`
float	`Schema.Number`
string	`Schema.String`
localized string	`Schema.String`
bool	`Schema.Boolean`
foreign key	`Schema.Number` (reference to another table ID)

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

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