README
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.
[Checkout the Source Code on GitHub](https://github.com/ivanpaulovich/jambo)
#### Requirements
* [Visual Studio 2017 + Update 3](https://www.visualstudio.com/en-us/news/releasenotes/vs2017-relnotes)
* [.NET CORE SDK 2.0](https://www.microsoft.com/net/download/core)
* [Docker](https://docs.docker.com/docker-for-windows/install/)
#### 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
REPOSITORY TAG IMAGE ID CREATED SIZE

```
$ 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.
```
2. Navigate to the Swagger UI at (eg. http://localhost:16024/swagger).
3. Post the following credentials:
```
{
"username": "ivanpaulovich",
"password": "mysecret"
}
```
4. __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..
```
3. __Attention:__ keep the Console App running for events processing.
#### How to run the Producer API
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.
```
2. Navigate to the Swagger UI (eg. http://localhost:14398/swagger).
