#data

Discover named datasets and run their generators using the selected Viteval configuration and selected destination providers. Evaluation tasks and scorers do not run during generation.

#Usage

viteval data [pattern] [options]

#Arguments

Quote patterns to prevent your shell from expanding them before Viteval runs.

#Options

#Discovery and persistence

Modules can use default exports, named exports, or multiple defineDataset() calls. Datasets inside evaluation files are discovered even when not exported. Aliases and re-exports of the same dataset generate it once. Distinct dataset objects with the same name fail instead of overwriting each other.

Existing datasets are preserved unless --overwrite is passed. Datasets with providers: [] run their generators without writing persisted files. Modules that fail during import do not publish their datasets.

Module-level code still runs on import. Keep expensive calls inside dataset generators or evaluation tasks.

#Examples

viteval data
viteval data "src/user-questions.dataset.ts"
viteval data --overwrite
viteval data --root ./app --config viteval.config.ts

See datasets for storage modes and defineDataset() for the generator API.
