JavaScript

A client library for building Dapr apps in JavaScript and TypeScript. This client abstracts the public Dapr APIs like service to service invocation, state management, pub/sub, secrets, and much more, and provides a simple, intuitive API for building applications.

Installation

To get started with the Javascript SDK, install the Dapr JavaScript SDK package from NPM:

npm install --save @dapr/dapr

⚠️ dapr-client is now deprecated. Please see #259 for more information.

Structure

The Dapr Javascript SDK contains two major components:

  • DaprServer: to manage all Dapr sidecar to application communication.
  • DaprClient: to manage all application to Dapr sidecar communication.

The above communication can be configured to use either of the gRPC or HTTP protocols.
