# Cosmiconfig Setup Set up cosmiconfig for hierarchical config loading. ## Capabilities - Configure cosmiconfig search paths - Set up format loaders (JSON, YAML, TOML) - Create TypeScript config support - Implement config caching - Handle config validation ## Generated Patterns ```typescript import { cosmiconfig, cosmiconfigSync } from 'cosmiconfig'; import { TypeScriptLoader } from 'cosmiconfig-typescript-loader'; const moduleName = 'myapp'; const explorer = cosmiconfig(moduleName, { searchPlaces: [ 'package.json', `.${moduleName}rc`, `.${moduleName}rc.json`, `.${moduleName}rc.yaml`, `.${moduleName}rc.yml`, `.${moduleName}rc.js`, `.${moduleName}rc.ts`, `.${moduleName}rc.cjs`, `${moduleName}.config.js`, `${moduleName}.config.ts`, `${moduleName}.config.cjs`, ], loaders: { '.ts': TypeScriptLoader(), }, }); export async function loadConfig(searchFrom?: string) { const result = await explorer.search(searchFrom); if (!result || result.isEmpty) { return { config: getDefaultConfig(), filepath: null }; } return { config: { ...getDefaultConfig(), ...result.config }, filepath: result.filepath }; } ``` ## Target Processes - configuration-management-system - cli-application-bootstrap - mcp-server-bootstrap
