// You can configure it manually as well, the most important parts are:
// const projectRoot = __dirname;
// const workspaceRoot = path.join(__dirname, '..', '..');
// #1 - Watch all files within the monorepo
// config.watchFolders = [workspaceRoot];
// #2 - Try resolving with project modules first, then hoisted workspace modules
// config.resolver.nodeModulesPaths = [
//   path.resolve(projectRoot, 'node_modules'),
//   path.resolve(workspaceRoot, 'node_modules'),
// ];

// Use turborepo to restore the cache when possible
config.cacheStores = [
  new FileStore({ root: path.join(__dirname, 'node_modules', '.cache', 'metro') }),
];
