ESLint Preset Configurator

Builds ESLint configuration outputs that rely on the package's bundled presets for both legacy .eslintrc and flat config formats, letting teams toggle strictness and environment flavors without re-declaring rule lists.

Capabilities

Legacy config assembly

• Given options specifying strictness and frameworks, returns a legacy config object whose extends stack starts with the package's recommended preset and layers optional strict/error emphasis and environment presets without duplicating entries. @test
• When TypeScript is enabled, the legacy config includes the package's TypeScript preset and merges parser options/resolver extensions for TypeScript without discarding existing settings. @test

Flat config assembly

• Produces a flat config array that registers the plugin once and composes the package's flat recommended preset with requested environment presets while keeping rule overrides separate from shared settings. @test

Preset toggles

• A warningsOnly flag switches the chosen package preset from strict/errors to the warnings-focused preset while preserving applied environment presets across both legacy and flat outputs. @test
