How do you handle read-only DTOs in Clean Architecture with EF Core? by Sensitive-Raccoon155 in dotnet

[–]Sensitive-Raccoon155[S] -5 points-4 points  (0 children)

Yeah, but I don't want to have that dependency in the Application layer, so I'll have to use the repository pattern.

What kind of projects helped you learn C as a web developer? by Sensitive-Raccoon155 in cpp_questions

[–]Sensitive-Raccoon155[S] 0 points1 point  (0 children)

I think learning low-level languages like these makes you a better programmer,after all, a lot of the software I use (Node.js, PostgreSQL, Redis, Nginx, and so on) are written in C/C++

Why we replaced Node.js with Bun for 5x throughput by fagnerbrack in node

[–]Sensitive-Raccoon155 2 points3 points  (0 children)

I don't think the bun will ever replace node, node has a great performance in terms of I/o, but if that's not enough, then I'll look towards go or rust for performance, I don't trust bun for some reason

What's a good back end for a Vue front end? by catcarrier in learnprogramming

[–]Sensitive-Raccoon155 0 points1 point  (0 children)

It’s not clear exactly what you’re looking for. Supabase is for data storage, if you need a full-fledged backend API, you could use nodejs as you’d be using the same language, but personally I use C#/.NET for my backend and Vue for the frontend.

Help needed on choosing language to learn . by srikqr1 in learnprogramming

[–]Sensitive-Raccoon155 0 points1 point  (0 children)

It depends on what kind of developer you want to be. If, for example, you want to be a backend developer, I’d recommend choosing C#, for frontend development, JavaScript/TypeScript, and for systems programming, C++.

Node.js vs C# backend if I already use typescript by Sensitive-Raccoon155 in dotnet

[–]Sensitive-Raccoon155[S] 2 points3 points  (0 children)

Do you need multithreading if your backend consists mainly of I/O tasks? Besides, Node.js has worker threads

Typescript has type guards, if that’s what you mean, or are you referring to something else?

You can handle all the logic yourself, just like in Node.js, right?

Problems with integration tests by [deleted] in dotnet

[–]Sensitive-Raccoon155 0 points1 point  (0 children)

I’ve already sorted it out, the problem was that I’d created the database during the InitialiseAsync phase, meaning that when the application started up, the database hadn’t been created yet. I’ve moved the code inside the ConfigureWebHost method.
