Generated Patterns

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 };
}
