Building sources

By default, apps run on the following ports:

Application	Port
Squirrel.Core	5050
Squirrel.Notifier	5070
RabbitMQ	5672

Tip: If you want to connect to the specific service outside of docker, then use "localhost" as a service name, but if both services are inside docker, use service_name from a "docker-compose" file instead.

Code quality

Make sure you read and follow .NET Quality Criteria. Also, there are some best practices for frontend development: Angular and Typescript

Docker:

1. Make sure you have Docker and Docker Compose.
2. Pull this repo to your machine.
3. You can build and run all application containers via docker-compose -f docker-compose.apps.yml up -d command.
4. You can pull and run all 3rd-party services (MSSQL Server, RabbitMQ) via docker-compose -f docker-compose.services.yml up -d command.
5. Happy coding! 😎

Setup environment for local development:

1. Download and install .NET 6 SDK.
2. It might be useful to have EF CLI. Install via command: dotnet tool install --global dotnet-ef
3. Download and install LTS version of Node.js
4. Install Angular-CLI via: npm install -g @angular/cli. What is Angular-CLI?

Extensions for frontend development (required):

• ESLint (analysis tool that checks TypeScript\JavaScript code for readability, maintainability, and functionality errors)
• EditorConfig (helps maintain consistent coding styles for multiple developers working on the same project)

Some extra extensions which can significantly help to work with Angular:

• Angular Language Service (intelliSense for Angular templates)
• Angular Snippets
• Angular Schematics (working with Angular schematics via UI)

Environment variables

This is a list of the required environment variables:

RabbitMQ

RABBIT_MQ_USERNAME - RabbitMQ username

RABBIT_MQ_PASSWORD - RabbitMQ user password

MSSQL Server

SA_PASSWORD - MSSQL Server "SA" user password

SQL Server Database Schema
