Financial Chat

Simple browser-based chatroom app that supports requesting financial data from the Stooq API by using the command /stock=stock_code

Setup

In order to run this application, the following tools are required:

• PostgreSQL
• RabbitMQ
• Node.js
• .NET Core

Database

After you have installed PostgreSQL from its official site and configured the server, create a database called chatroom. In a new terminal, access the psql CLI and execute
CREATE DATABASE chatroom;
No further steps are required as the tables and relationships should be automatically created by the Entity Framework code-first migrations. Of course, migrations could be manually run at any time by executing dotnet-ef database update after navigating to the \FinancialChat.Domain folder.

Node.js

Node.js is required for running the frontend, which has been built with React/Redux.

RabbitMQ

The app uses RabbitMQ as a message broker. You can install RabbitMQ via Chocolatey by running
choco install rabbitmq
or by downloading the official installer from the official page

Before running the app, make sure that both postgresql and rabbitmq services are running. On a Windows terminal run
net start postgresql
net start rabbitmq
also check that the npm and dotnet programs are added to the PATH.

Running the app

1. First, run the Bot service by accessing \FinancialChat.Bot and start this console project app with by running
   dotnet run
   This will start the server from this simple RPC communication system and listen to requests in the queue.

2. Next, cd to \FinancialChat.Web and start the Web project by running
   dotnet run
   This should internally run an npm install command (to recover all packages required for the frontend) and also run the database migrations, which are going to be run only the first time the app is run pointing to that particular database. The app should run at the port specified in launchSettings.json, which in this case are 5000 and 5001. Therefore, the URL will be localhost:5000 or localhost:5001.

3. Since the API and the SignalR hub require authorization, a user has to be created in order to obtain the token. The UI only supports login, we'll have to create a user with the API. For that, make a request to
   POST /api/account/register
   with the following body

   {
   	"username": <username>,
   	"password": <password>
   }
   

   After that, you should be able to log in via the UI or make other API calls with the obtained Bearer token.

4. Finally, go to either https://localhost:5000/ or https://localhost:5001/ to access the chatroom application.
