A solution based on a Event-Driven architecture with DDD and CQRS. The solution contains the following applications.

  • A Producer Web API which receives Commands to produce Domain Events. This one also receives Queries and returns JSON.
  • A Consumer Console App that reads the Event Stream and do a projection to a MongoDB database.
  • A Web API for authentication and JWT generation.

Requirements

Environment setup

If you already have valid connections for Kafka and MongoDB you could skip this step and go to Running the applications step.

  • Run the ./up-kafka-mongodb.sh bash script to run Kafka and MongoDB as Docker Containers. Please wait until the ~800mb download to be complete.
$ ./up-kafka-mongodb.sh

  • Check if the data layer is ready with the following commands:
$ docker images

$ docker ps

If Kafka is running well it will be working with the 10.0.75.1:9092 connection string. if MongoDB is running well it will be working at mongodb://10.0.75.1:27017 connection string.

Running the applications

You have two options to run the applications, one is by opening with Visual Studio 2017 and the other is by running dotnet core commands.

Option 1 - Running with Visual Studio 2017

Open the three solutions on three Visual Studios them run the following projects.

  • Jambo.Auth.UI.
  • Jambo.Consumer.UI.
  • Jambo.Producer.UI.

Option 2 - Running with dotnet commands

How to run the Bearer Authencation API

  1. Run the command dotnet run at source\Auth\Jambo.Auth.UI folder.
$ dotnet run
Using launch settings from C:\git\jambo\source\Auth\Jambo.Auth.UI\Properties\launchSettings.json...
Hosting environment: Development
Content root path: C:\git\jambo\source\Auth\Jambo.Auth.UI
Now listening on: http://localhost:16024
Application started. Press Ctrl+C to shut down.
  1. Navigate to the Swagger UI at (eg. http://localhost:16024/swagger).
  2. Post the following credentials:
{
  "username": "ivanpaulovich",
  "password": "mysecret"
}
  1. Store the Bearer Token because you will need the token value to log on Producer API.
{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiJhYzA4MmE3OS1lMWY3LTQ4MTktYmU1Mi1hOTQwMTBkM2VjZTciLCJzdWIiOiJzdHJpbmciLCJleHAiOjE1MTI0Nzg5ODgsImlzcyI6Imh0dHA6Ly9teWFjY291bnRhcGkiLCJhdWQiOiJodHRwOi8vbXlhY2NvdW50YXBpIn0.9YKGmKaptLBDcExHhPOQ3_j9TsdbkcRf8ZtvIkdq8Go",
  "expiration": "2017-12-05T13:03:08Z"
}

How to run the Consumer API

  1. Run the command dotnet run at source\Consumer\Jambo.Consumer.UI folder
$ dotnet run
11/5/2017 11:17:20 AM Waiting for events..
11/5/2017 11:18:20 AM Waiting for events..
11/5/2017 11:19:20 AM Waiting for events..
11/5/2017 11:20:20 AM Waiting for events..
11/5/2017 11:21:20 AM Waiting for events..
11/5/2017 11:22:20 AM Waiting for events..
  1. Attention: keep the Console App running for events processing.

How to run the Producer API

Authorization

  1. Run the command dotnet run at the source\Producer\Jambo.Producer.UI folder.
$ dotnet run
Using launch settings from C:\git\jambo\source\Producer\Jambo.Producer.UI\Properties\launchSettings.json...
Hosting environment: Development
Content root path: C:\git\jambo\source\Producer\Jambo.Producer.UI
Now listening on: http://localhost:16959
Application started. Press Ctrl+C to shut down.
  1. Navigate to the Swagger UI (eg. http://localhost:14398/swagger).
