Rapid Dapr



Rapid Pub/Sub Approach to aid in getting started with Dapr, .NET and Bicep.

## The idea

In a previous repo, A Pub/Sub model was introduced but having in mind 

the goal of bringing about a great development experience. An integrated development experience was not always the case in the plethora of Dapr examples

that inhabit the internet.

However, In this repo I take a step further into actualizing, bringing the actual 

solution to market, or in other words live. A great inspiration to this idea was [awesome-azd.](https://azure.github.io/awesome-azd/?name=dapr)

While the templates in this portal are compelling, There was an envisioned use case that was not to be found there. 

This use case involved the following ingredients: Azure Service Bus - Multiple Topics, Multiple Subscriptions, .NET Shared Class Libraries -

with a common library for avoiding magical strings on topics.

This boilerplate uses the concept of bicep templates and the azd cli toolkit

to bring to production a working solution. The bicep templates are used to create the infrastructure and the azd cli toolkit 

is used to deploy the application. 

## Enhance

Introduce or remove additional topics in the servicebus.bicep file. 

For instances under the *serviceBusNamespace* resource, topics could be define as follows:

```bicep

param activityTopic string = 'activity'

param subName string = 'sub'

resource serviceBusNamespace 'Microsoft.ServiceBus/namespaces@2021-06-01-preview' = {

  name: serviceBusNamespaceName

  location: location

  .....

  resource topic 'topics' = {

    name: activityTopic

    properties: {

      supportOrdering: true

    }

    resource subscription 'subscriptions' = {

      name: subName

      properties: {

        deadLetteringOnFilterEvaluationExceptions: true

        deadLetteringOnMessageExpiration: true

        maxDeliveryCount: 10

      }

    }

  }

}

```

Finally, ehance the Subscriber and Publisher controllers to produce and emit the

desired event based on the subscriptions. 

#### Publisher

```csharp

        [HttpPost(DaprTopics.Activity)]

        public async Task PostMessage([FromBody] ActivityMessageDTO message)

        {

            Console.WriteLine($"Calling Publish Action:- {message.Key}, DateTime: - {DateTime.Now}");

            await activityHelper.PublishToTopic(DaprTopics.Activity, message);

            return Ok();

        }

```

#### Subscriber

```csharp

        [Topic(DaprActivityConfig.PUBSUB, DaprTopics.Activity)]

        [HttpPost(DaprTopics.Test)]

        public IActionResult Post([FromBody] ActivityMessageDTO message)

        {

            Console.WriteLine($"Published topic:{DaprTopics.Test} Action:- {message.Key}, DateTime: - {DateTime.Now}");

            return Ok();

        }

``` 

## Deploy

Thanks to the azd cli toolkit, the deployment of the application is as simple as running the following command:

```bash

azd login

azd up

```
