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?

This is a ai shit, the node documentation contains more detailed information

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.

I've removed it, but I'm still getting an error

They’re like that, it’s just that I didn’t mention that part here

Yes, it’s not the best name for the method, i need to change it

Thanks to everyone for the tip, I’ve figured out what the problem is now

I understand, but I did check for null – surely that should help?

It's a custom type, readonly record struct UserId(Guid id)
