Dapr is a portable runtime that gives your applications APIs for durable workflows, AI, messaging, state and more, in any language; this repository holds small, runnable samples for each of those APIs.
If you are new to Dapr and haven't done so already, it is recommended you go through the Dapr Getting Started instructions.
Pick a building block API (for example, PubSub, state management, etc) and rapidly try it out in your favorite language SDK (recommended), or via HTTP. Visit the Dapr Docs Quickstarts Guide for a comprehensive walkthrough of each example.
| Dapr Quickstart | Description |
|---|---|
| Workflow | Durable execution with Dapr Workflow: the workflow saves its progress as it runs, so a long-running, stateful process picks up where it left off after a crash or restart |
| AI | A durable AI workflow that has an LLM (OpenAI, Gemini or Anthropic) review a contract and pauses for human approval when the risk is high |
| Conversation | Send prompts to large language models (LLMs) from different providers through one consistent API, including tool calling |
| Publish and Subscribe | Asynchronous communication between two services using messaging |
| Service Invocation | Synchronous communication between two services using HTTP |
| State Management | Store a service's data as key/value pairs in supported state stores |
| Search | Index documents and search their content using the Search API (C# only) |
| Bindings | Work with external systems using input bindings to respond to events and output bindings to call operations |
| Secrets Management | Securely fetch secrets |
| Actors | Create stateful, long running objects with identity |
| Configuration | Get configuration items as key/value pairs or subscribe to changes whenever a configuration item changes |
| Cryptography | Perform cryptographic operations without exposing keys to your application |
| Resiliency | Define and apply fault-tolerant policies (retries/back-offs, timeouts and circuit breakers) to your Dapr API requests |
| Jobs | Dapr Jobs enable you to manage and schedule tasks |
The SDK quickstarts use the Dapr SDKs for Python, Go, .NET, Java and JavaScript. To build AI agents on top of Dapr, see Dapr Agents.
Go deeper into a topic or scenario, oftentimes using building block APIs together to solve problems (for example, build a distributed calculator, build and deploy an app to Kubernetes).
| Tutorials | Description |
|---|---|
| Hello-world | Demonstrates how to run Dapr locally. Highlights service invocation and state management. |
| Hello-kubernetes | Demonstrates how to run Dapr in Kubernetes. Highlights service invocation and state management. |
| Distributed-calculator | Demonstrates a distributed calculator application that uses Dapr services to power a React web app. Highlights polyglot (multi-language) programming, service invocation and state management. |
| Pub-sub | Demonstrates how to use Dapr to enable pub-sub applications. Uses Redis as a pub-sub component. |
| Bindings | Demonstrates how to use Dapr to create input and output bindings to other components. Uses bindings to Kafka. |
| Observability | Demonstrates Dapr tracing capabilities. Uses Zipkin as a tracing component. |
| Secret Store | Demonstrates the use of Dapr Secrets API to access secret stores. |
| Workflow | Demonstrates how to author and manage Dapr workflows. Includes workflow patterns, resiliency, and common challenges & tips. |
