Community driven repository for Dapr samples
Note: The Dapr samples have been recently reorganized. Samples that are aimed for newcomers and are meant to help users get started quickly with Dapr have been migrated to a separate repository dapr/quickstarts.
Samples in this repository showcase Dapr capabilities using different languages and address wide array of common scenarios. Some focus on specific usage patterns or particular Dapr capability while others are end-to-end demos leveraging several Dapr building blocks and capabilities.
If you are new to Dapr, you may want to review following resources first:
Note, these samples are maintained by the Dapr community and are not guaranteed to work properly with the latest Dapr runtime version.
| Sample | Details | |------|-------| | Twitter Sentiment Processor | Code sample used to demo Dapr during Microsoft's Build 2020 conference showing a polyglot distributed application which performs sentiment processing for tweets | | Hello world slim (no Docker dependency) | This sample is a version of the hello-world quickstart sample showing how to install initialize and use Dapr without having Docker in your local environment | | Hello TypeScript | This sample is a version of the hello-world quickstart sample showing how to use Dapr in a TypeScript project. | | Docker compose sample | Demonstrates how to get Dapr running locally with Docker Compose | | Dapr, Azure Functions, and KEDA | Shows Dapr being used with Azure Functions and KEDA to create a polygot Functions-as-a-Service application which leverages Dapr pub/sub | | OAuth Authorization to external service | Demonstrates how to inject a service principal OAuth Bearer Token within a Dapr service-to-service invocation to call secured APIs | | Read Kubernetes Events | Shows Dapr being used with the Kubernetes Input binding to watch for events in Kubernetes cluster | | Batch File Processing | This sample demonstrates an end-to-end sample for processing a batch of related text files using microservices and Dapr. Through this sample you will learn about Dapr's state management, bindings, Pub/Sub, and end-to-end tracing. | | Dapr integration in Azure APIM | Dapr configuration in Azure API Management service using self-hosted gateway on Kubernetes. Illustrates exposing Dapr API for service method invocation, publishing content to a Pub/Sub topic, and binding invocation with request content transformation. | | Distributed Calendar | Shows use of statestore, pubsub and output binding features of Dapr to roughly create a distributed version of a MVCS architecture application. |
| Sample | Details | |------|-------| | Dapr RetroPOS | Dapr Retro Point of Sales is a sample of backend workflow based on microservices. | | Dapr Traffic Control | Simulated traffic-control system with speeding cameras using Dapr pub/sub and service-to-service invocation. |
Each sample includes README.md which provides information about the validated versions of Dapr for that sample.
If you would like to have a sample updated or better yet, update it yourself to a newer version of Dapr, please see the contribution guide to learn more about opening issues and submitting pull requests to this repository.
Note, over time, for maintainability reasons, some samples may be removed from this repository.
If you want to contribute a sample to this repo, please see the sample contribution guide for details on the PR process.
Samples should follow these high-level guiding principles:
Along with the sample code and README, samples should be listed in this page in the above samples table
Sample info section at the top of the main sample README should follow the following template:
| Attribute | Details | |--------|--------| | Dapr runtime version | vX.X | | Language | [Languages used in the sample code] | | Environment | [Environment name] |
Note: If you are not sure what Dapr runtime version you are running, use the Dapr CLI commanddapr --version
| Attribute | Details | |--------|--------| | Dapr runtime version | v0.7.1 | | Language | Go, C# (.NET Core), Node.js | | Environment | Local or Kubernetes |
