@retemper/lodestar-config

Config loading, normalization, and merging.

import { loadConfigFile, resolveConfig, mergeConfigs } from '@retemper/lodestar-config';

loadConfigFile(dir)

Load a lodestar config file from the given directory. Searches for lodestar.config.ts, .mjs, .js in order.

const config = await loadConfigFile('/path/to/project');
// config: WrittenConfig | null

resolveConfig(written, rootDir)

Normalize a WrittenConfig into a fully resolved ResolvedConfig:

const resolved = resolveConfig(writtenConfig, '/path/to/project');

• Expands shorthand rule configs ('error' → { severity: 'error', options: {} })
• Normalizes plugin entries
• Applies defaults for include, exclude, baseline

mergeConfigs(base, override)

Merge two configs. Rules from override take precedence. Plugins accumulate.

const merged = mergeConfigs(rootConfig, packageConfig);

discoverWorkspaces(rootDir)

Discover workspace packages from pnpm-workspace.yaml or package.json workspaces field.

const packages = await discoverWorkspaces('/monorepo/root');
// [{ name: '@scope/pkg', dir: '/monorepo/root/packages/pkg' }, ...]
