# ObjectRef

> TypeScript SDK reference

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

Represents a reference to a saved Weave object.

Generally, end users will not need to interact with this class directly.

An ObjectRef contains the project ID, object ID, and digest that uniquely identify
a saved object in Weave's storage system.

## Example

```ts twoslash theme={null}
// @noErrors
const ref = new ObjectRef('my-project', 'abc123', 'def456');
const uri = ref.uri(); // weave:///my-project/object/abc123:def456
```
