Modules

• Pipeline — pipeline orchestrator with fluent API
• Source — array and generator source factories
• Transform — map, filter, validate, flat-map transforms
• Sink — array, null, callback, and batch sinks
• EtlError — structured errors with stable codes
• Schemas — Zod schemas for pipeline types
• Types — shared TypeScript interfaces

Quick Start

import { createPipeline, arraySource, mapTransform, ArraySink } from "@suaveplan/etl";

const sink = new ArraySink<number>();
const result = await createPipeline({ source: arraySource([1, 2, 3]) })
  .pipe(mapTransform((n) => n * 2))
  .to(sink)
  .run();

console.log(result.stats.loaded); // 3
console.log(sink.records); // [2, 4, 6]
