downflux / BaseTransformer

Class: BaseTransformer<TExec, TResult>

Defined in: packages/base/BaseTransformer.ts:33

Fetches a target URL and converts parser output into execution metadata.

Remarks

Transformers sit between HTTP fetching and pipeline building. They combine common parser output with provider-specific parser output, then provider subclasses can map those raw fields into stable public result types.
