# Low-level Pipeline API

> Build custom task pipelines with the pipeline namespace exported by @cognee/cognee-ts.

The original pipeline engine API is available under the `pipeline` namespace:

```ts theme={null}
import { pipeline, init } from '@cognee/cognee-ts';

init();

const task = pipeline.createTask((input: pipeline.CogneeValue, ctx: pipeline.TaskContext) => {
  // process input …
  return input;
});

const p = new pipeline.Pipeline("my pipeline");
p.addTask(new pipeline.TaskInfo(task));

const [result] = await p.execute([pipeline.CogneeValue.fromString("hello")], ctx);
```

All pipeline symbols are also available as flat re-exports at the top level of
`@cognee/cognee-ts`:

```ts theme={null}
import {
  Pipeline,
  TaskInfo,
  createTask,
  CogneeValue,
  TaskContext,
  RunHandle,
  CancellationHandle,
  CancellationToken,
  createCancellationPair,
  ProgressToken,
  Watcher,
  createWatcher,
  createNoopWatcher,
} from '@cognee/cognee-ts';
```
