Binary Store

The Dapr JavaScript SDK lets Node.js applications store, retrieve, stream, and delete binary files in a configured Dapr binary store component. Use DaprClient.binaryStore with either HTTP or gRPC to stream large files or work with bytes already held in memory.

Binary Store requires Dapr runtime 1.19 or later and JavaScript SDK 3.19.0 or later. The underlying Binary Store API is alpha.

To get started, follow the Binary Store how-to guide. See the client usage guidance for configuration, memory use, cancellation, and errors.
