adapter-lint-staged

Generates a .lintstagedrc.json config file that maps glob patterns to commands. This is a setup-only adapter: lint-staged is invoked by husky, not by lodestar directly.

Package: @retemper/lodestar-adapter-lint-staged

Managed file: .lintstagedrc.json

Config Options

Option	Type	Description
commands	Record<string, string | readonly string[]>	Glob pattern to command mapping -- e.g., {"*.ts": "eslint --fix"}

Example

import { lintStagedAdapter } from '@retemper/lodestar-adapter-lint-staged';

lintStagedAdapter({
  commands: {
    '*.{ts,tsx}': 'eslint --fix',
    '*.{css,scss}': 'stylelint --fix',
    '*.{ts,tsx,css,scss,json,md}': 'prettier --write',
  },
});

How verifySetup Works

1. Checks that .lintstagedrc.json exists in rootDir.
2. Reads the file content and compares it against the JSON that lodestar config produces from the commands mapping.
3. Returns a missing violation if the file does not exist.
4. Returns a drift violation (with a diff of expected vs actual) if the content does not match.
5. Returns no violations if .lintstagedrc.json matches.

Drift means the .lintstagedrc.json file was manually edited or overwritten by another tool, so it no longer reflects the lodestar config. Running lodestar check --fix regenerates the file to resolve the violation.

Note: This adapter does not implement check(). lint-staged is triggered by husky git hooks, not by lodestar check.
