recommendedInstall

✓ import { recommendedInstall } from 'eslint-babel-migrate'

Used to get the install command for the maintained parser.

Migrates an ESLint config from babel-eslint to @babel/eslint-parser and prints the new config, changes, and install command.

import { migrateBabelEslintConfig } from 'eslint-babel-migrate'; const oldConfig = { parser: 'babel-eslint', parserOptions: { sourceType: 'module' }, plugins: ['@babel'], }; const result = migrateBabelEslintConfig(oldConfig); console.log('Migrated config:', result.config); console.log('Changes:', result.changes); console.log('Install command:', result.install);

Debug

Known issues

breakingInput config parser must be exactly 'babel-eslint'; case-sensitive.

fix

Ensure the parser string is 'babel-eslint' (lowercase).

affects: >=0.0.0

deprecatedPackage is a migration helper; it will not be updated for future parser changes.

fix

After migration, consider using @babel/eslint-parser directly.

affects: >=0.0.0

gotchaReplaces only the parser and known legacy options; custom plugins not automatically migrated.

fix

Manually review and migrate any custom Babel plugins.

affects: >=0.0.0
