GitHub - actions/github-script: Write workflows scripting the GitHub API in JavaScript Write workflows scripting the GitHub API in JavaScript - actions/github-script

TIL about github.com/actions/gith...

Which allows you to run a bit of JS in your #github actions pipeline, and sets up some default context values for you

I needed to run a bit of logic to extract some information from the tag name that executed a build... this was just what I was looking for

Thinking we know it all is very dangerous!

What will stop us from learning?

GitHub - Tyrrrz/CliWrap: Library for running command-line processes Library for running command-line processes. Contribute to Tyrrrz/CliWrap development by creating an account on GitHub.

Even better if you use CliWrap
github.com/Tyrrrz/CliWrap

let! result = Cli.Wrap("path/to/exe")
.WithArguments([
"--foo"
"bar"
])
.WithWorkingDirectory("work/dir/path")
.ExecuteAsync()

3. Javascript automation script can do anything you can think of.

Personally I hate writing shell scripts because of weird syntax, hard to reuse, zero testability, mostly I think I am not smart enough for it and I am more than ok with it. For me, simplicity wins.

Instead of writing shell scripts for automation, write them in Typescript or JavaScript and run them with node:

1. Way easier to write and maintain and AI will happily do it for you with higher correctness than the shell scripts

2. Its platform agnostic! Node runs the same way on windows/Linux/mac

Zero mocks means less code to maintain. Tests ignorant of implementation details are also remarkable easy to write and maintain, and they bring freedom to refactoring which lead to easy to read maintainable code.

testing the .net webapi backend(ef and postgres) from the outside using Testcontainers library and .net’s WebApplicationFactory also give us very high degree of confidence. Game changer.

Being able to test the whole web application as a black box from outside with Playwright is a project saver. Its like having tons of QAs checking everything all the time. Docker is one the best thing happened to the software industry!

The complexity of a distributed microservice architecture with event sourcing and document db is probably 100 times more than a modular monorepo with relational databases!

Take away: ef core 9 support value object in many ways, however I ended up not using any of them:

1. eager loading collection of value object causes performance issue

2. the non-collection value object are treated as stealth entity, polluting audit trails.

I do not like the look of the audit log with an implementation detail like owned entity jamming up the audit trail. So with regret, I unpacked the all and use regular properties instead for cleaner audit trails.

Moving on, I also implementation audit trails to record all transactions, for the capability of being able to roll back transitions. Then I found that The single owned entity in the domain is being treated as separate entitiy by ef core therefore they uses one entry in the audit log…

I am happy with middle ground achieved above where I can apply DDD and enjoy the best performance, with a bit of hack.

However these operators are not without downsides. I ended up using regular entities for collection of value object and make them inaccessible from the DBContext to force the use of aggregate. Those entity models can so implementation ValueObject behaviors, Id being one of the property for equality

Collection of value objects are mapped to separate tables and they are always eager loaded with the aggregate, this causes potential performance issue. For read only queries, we can use AsNonTracking to improve performance and for commands we can use AsSplitQuery.

I am having so much fun with dotnet 9 and ef core 9. Ef core have very good support Domain Driven Design, we can use owned entities to model value objects and they are mapped in the database sensiblely. Ef core has good default rules, but we can configuration to the teeth.🧵

Just fixed a bug, the remix app rerun the root loader on every page. Turns out we have a link loading favicon and the icon file is missing, adding it fixes the problem.

My guess is the browser tries to reload the missing favicon which is a navigation action, causing a reloading the app.

Maybe the news is too new, did a search, seems no other news reporting the same. Scaled back but nothing about stopping the production.

I can remember what I asked ChatGPT for help in the past few months:

In one of my project, I send messages via SignalR when data updated, react query would invalidate the relevant query, so simple to do and improved user experience by a mile.

Missing the power of react-query in the remix app I am working on. Cannot wait for TanStack Start!

Wait for it, AI will start generating typos…
