1. Pull repository locally and run the API in Visual Studio or deploy all necessary files in IIS.

2. Configure connection string and Token options in AppSettings.{env}.json. "DefaultConnection": "Host=localhost;Port=5432;Username=;Password=;Database=;"

3. Install Postgress where the DB will be deployed. If the database will run in a local machine, run "cmd.exe" on ~/JobsityFinancialChat.Domain and run the following command "dotnet ef database update". It will run all necessary migration files to create and put the database up-to-date. (note 1)

4. Once the WebApi is deployed, go to the Frontend folder and run the UI. Click on "init.html" and enter your user credentials**. If the WebAPI is running in a local environment, a new user must be created with:

Host: localhost:57092
Content-Type: application/json
cache-control: no-cache
Postman-Token: af0dcf4c-91ce-4f10-822a-76a19282831d
{
  "firstName": <firstName>,
  "firstName": "string",
  "email": "user_2@company.com",
  "password": <password> // Password must have at least 8 characters, an Uppercase letter, a symbol and a number. (i.e."A$2WEe_1")
}     

5. After the user is authenticated, the UI saves the user token which is retrieved from the login endpoint. This process is automatic.

6. The user will see a list of available chatrooms, where he/she can join in (note 3). After the user selects a chatroom, the API retrieves the last 50 messages sorted by created date.

7. The user can post messages as commands into the chatroom with the following format /stock=stock_code. The message will be a stock quote using the following format: “APPL.US quote is $93.42 per share.

8. All users that belong to the chatroom should see all the messages, but the command messages are not stored in the DB.

(note 1) There's a remote server DB that can be used. Please send an email to ddonari@gmail.com to get access.

(note 2) There are preexisting users in the remote database. Please send an email to ddonari@gmail.com to get access.

(note 3) The API provides an endpoint that can be used to create new chat rooms:

Host: localhost:57092
Content-Type: application/json
Authorization: Bearer <<BEARER TOKEN>>
User-Agent: PostmanRuntime/7.18.0
Accept: */*
