lewee's Introduction

Hi there 👋

I'm a .Net engineer based in Brisbane, Australia.

I've been working in .Net since I graduated from the University of Queensland in 2007.

I am currently employed by Workday (I work on the Adaptive Planning product).

I'm a father of two, partner to one.

I enjoy watching football (soccer), but enjoy the analysis of games more than actually watching the games (maybe that's the engineer in me).

My GitHub username, TheMagnificent11, is play on words with the old "The Magnificent Seven" movie and my favourite football player at the time I signed up to GitHub, Ryan Giggs, who wore the number 11 shirt for Manchester United, which is my favourite football team.

My main software engineering interests include domain-driven design and observability.

Currently, I'm trying to get my head around OpenTelementry.Net and how to integrate it with Grafana and Loki.

  • 🔭 I’m currently working on Lewee
  • 🌱 I’m currently learning how to push traces and metrics to from .Net applications to Grafana.
  • 👯 I’m looking to collaborate on Lewee.
  • 🤔 I’m looking for help using .Net Aspire to deploy applications to Azure Container Apps while using Azure AD B2C for authentication and Azure Key Vault for secret management.
  • 💬 Ask me about domain-driven design or football.
  • 📫 How to reach me:
  • 😄 Pronouns: he/him
  • ⚡ Fun fact
    • My surname, Weerasingham, has a typo. It should start with "V".
    • In Sri Lanka, where I was born, there are two main languages, Singhalese and Tamil.
    • The Tamil spelling is "Veerasingham" and Singhalese spelling is "Weerasinghe", so mine is a mix of both because the family friend that registered my dad's birth was Singhalese and he made a mistake, but my dad decided to keep the incorrect spelling.

lewee's Issues

Upgrade to .Net 8

  • Upgrade to .Net 8
  • Upgrade all package dependencies
  • Update the README

`Lewee.Blazor.Fluxor` - Change Logging

Change the logging in Lewee.Blazor.Fluxor to use Seriloginstead of the standard Microsoft logging.

Also, implement Seq ingestion in Lewee.Infrastructure.AspNet.

Add documentation with code examples to the appropriate README files.

Simplify `Lewee.Blazor` setup

There's a lot of steps to setup Fluxor and SignalR in Lewee.Blazor.

Ideally this should be done fluently via IServiceCollection extension methods and a single "initializer" component.

`README` files for each NuGet package

Create README files for each NuGet package with code examples (or links to the sample application files).

Reference each README in the appropate csproj file.

Each README file should also contain a NuGet badge.

Dispatch domain events to a queue

Currently, an outbox pattern is used to dispatch domain events; domain events are written as JSON to the DomainEventReferences table, and a background service looks up new domain events, dispatches them and marks them as dispatched.

This happens every few seconds.

An improvements might be to leverage a post-save Entity Framework event to dispatch new domain events to a queue or service bus, probably using MassTransit (to allow the user to choose the type of queue they wish to use), and then have a worker(s)/subscriber(s) that action these domain events.

That way, dispatching doesn't need to happen using a background service that sleep for a couple of seconds before checking for new domain events.

Once dispatched to the queue, the locking and retry-logic of the queue deals with the domain events.

Postgres Support

Split Lewee.Infrastructure.Data into Lewee.Infrastructure.SqlServer and Lewee.Infrastructure.Postgres

Unit tests on `ValueObject` causes stack overflow

Unit tests on classes that inherit Lewee.Domain.ValueObject<T> classes a stack overflow because of the generic parameter causes a circular dependency.

The active test run was aborted. Reason: Test host process crashed : Stack overflow.

Aspire

  • Remove Docker Compose and replace it with Aspire
  • Remove unnecessary solution files and and only use Lewee.sln
    • Modify workflows to use Lewee.sln, ensuring only appropriate projects are packed
  • Update the README to reflect the new developer experience with Aspire

README - Logging

Add logging instructions to the README for Lewee.Infrastructure.AspNet

Fix Publish Workflow

The NuGet push task in publish.yml does not work.

Also update the main README to display the NuGet badges.

Fix intermittent test failure

GetTables_ShouldReturnTheCorrectTables passes when run with a new database.

It then fails on subsequent runs.

There seems to be an issue with resetting the database before each test.

"Authorisation behaviours" to include in `Mediatr` pipelines

There's two types of authorisation that I think needs to be addressed:

  1. Authorisation to only allow a site administrator (or super administrator) to access the query/command
  2. Authorisation that requires the user to have a "claim" to something to access the query/command
    • Tenant membership
    • Tenant role
    • A combination of tenant membership and tenant role

Possible Solution

Administrator Authorisation

Create IAdministratorRequet interface that can be added to commands and queries and then used for authorisation in an AdministratorBehavior.

Claims Authorisation
