PKU426: Config Type Not Found

Error Message​

[PKU426] Could not find Config type in typesLookup. Make sure you have a Config interface extending CoreConfig in your codebase.

What Went Wrong​

Pikku couldn't find a Config interface in your TypeScript codebase. Pikku requires a Config type to understand your application's configuration structure.

How to Fix​

Create a Config interface that extends CoreConfig:

// src/config.ts or src/types.ts
import { CoreConfig } from '@pikku/core'

export interface Config extends CoreConfig {
  // Add your custom config properties
  apiKey: string
  databaseUrl: string
  environment: 'development' | 'production'
}

Then export it in your services setup:

// src/services.ts
import { CreateConfig } from '@pikku/core'
import type { Config } from './config'

export const createConfig: CreateConfig<Config> = async () => {
  return {
    apiKey: process.env.API_KEY!,
    databaseUrl: process.env.DATABASE_URL!,
    environment: (process.env.NODE_ENV as any) || 'development',
  }
}

Minimal Example​

If you don't need custom config, you can use an empty interface:

import { CoreConfig } from '@pikku/core'

export interface Config extends CoreConfig {
  // No custom properties needed
}

Common Mistakes​

  • Forgetting to extend CoreConfig
  • Naming the interface AppConfig or Settings instead of Config
  • Not exporting the Config type
  • Placing the Config type in a file that's not scanned by the CLI

Where to Place Config​

The Config interface should be in one of your srcDirectories specified in pikku.config.json:

{
  "srcDirectories": ["src"],
  "outDir": ".pikku"
}
