# Settings

> TypeScript SDK reference

> **Settings** = `object`

Defined in: [src/settings.ts:3](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/settings.ts#L3)

## Properties

### attributes

> `readonly` **attributes**: `Record`\<`string`, `any`>

Defined in: [src/settings.ts:14](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/settings.ts#L14)

### genai

> `readonly` **genai**: `object`

Defined in: [src/settings.ts:23](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/settings.ts#L23)

#### batchOptions?

> `optional` **batchOptions?**: `BufferConfig`

`BatchSpanProcessor` configuration. Ignored unless `spanProcessor === 'batch'`.

#### spanProcessor?

> `optional` **spanProcessor?**: `"batch"` | `"simple"` | `SpanProcessor`

How GenAI spans are exported.

* `'batch'` (default): `BatchSpanProcessor`, suitable for production
  agents and long-lived processes.
* `'simple'`: `SimpleSpanProcessor`, one HTTP POST per span. Useful for
  tests and short-lived CLIs where deterministic flush matters more than
  throughput.
* `SpanProcessor` instance: a user-supplied processor. The caller owns
  its lifecycle; the Weave OTLP exporter targeting `/agents/otel/v1/traces`
  is not used.
