My docker-compose and my applications should than use one configuraion file with external ports? What if I create more instances of the same container? Should I update then the shared configuraion file? It is practicable?

TeBeCo

@tebeco

via configuration

choose your preferred way

env / cli arg / file / mount / ...

who does the port mapping ? the host
who has to inform the container ? the host

that's about it

a static config file sounds like a bad idea if the host can decide to change port mapping later on

env var from compose file is a possibility of you name that properly like ASPNETCORE__WHATEVER (i don't recall if it's one or two underscore)

issue with that is that you have to put the env var into the compose file

i wish there was a way to see -e from cli

like
docker compose up -e <service>:<env>:<value> but i don't think that's a thing

Hi all, I've got a Razor Pages app where I'm trying to create the following page: /venues/{venue-name}/gigs , where {venue-name} is dynamic. The best I've come up with is to create a Venues Razor Page with a page directive like @page "{venue-name?}/{gigs?}", then check in the code behind that gigs == "gigs", but this feel pretty wrong. Any ideas/suggestions?

Marcus Turewicz

@marcusturewicz

Think I got it, TIL:

services
    .AddRazorPages()
    .AddRazorPagesOptions(options =>
    {
        options.Conventions.AddPageRoute("/Venues/Gigs", "venues/{venuePath?}/gigs");
    });

@marcusturewicz you know you can always use attribute routing, which gives much more control over routing options

WebView2?

@aloksharma1

WebView2?

will try this too

does anybody ever implemented filewatchers in asp.net core, all examples that i see are either dotnet tools or windows/service/console apps

Alberto Passalacqua

@AlbertoPa

filewatcher for? do you want to show the output in a web page?

Alok Sharma

@aloksharma1

i want to keep my css/js etc files precompressed

so I'll preface this by saying I'm probably doing something unusual

but

when using Minimal APIs to map endpoints, is there a way to have it map the params to an object?

so, when you do .MapGet("some/url/structure", (string foo, int bar) => HandleRequest(foo, bar));

instead of having to explicitly delcare all the params foo and bar there, can you just give it MyRequestObject that has properties Foo and Bar and have it do model binding?

Michał Zegan

@webczat

i think minimal api does not have advanced full featured model binding. it's minimal for a reason

Nicholas Budd

@anaximander23

hmm

maybe I could do this using the full Map methods instead

basically, I've been working with this framework I've developed for use in APIs that uses a Result<T> type to let you signal error results without exceptions, for cases where errors are expected and not exceptional

so you can do stuff like return Results.NotFound<User>(query.UserId); rather than having to throw new UserNotFoundException(query.UserId);

Michał Zegan

@webczat

minimal api is minimal for a reason... and other map methods are doing direct route mapping to a low level request delegate

Nicholas Budd

@anaximander23

so, we noticed that now that I've implemented automated mapping of Result<T> types to relevant HTTP results, all our controller methods are identical

literally just

var result = await _mediator.Send(query);
return MapToResponse(result);

in every controller method

Custom Binding

Nicholas Budd

@anaximander23

so I was wondering if there's a way to hook up something that registers that for stuff, but using different types of query

I have it working mostly, but it's complaining that the body type is inferred and that's not allowed

Custom Binding

that looks promising but might require consuming applications to write binders for everything

which... isn't the worst thing, but I was hoping to avoid it

that said... in theory I could pull the URL, body, and query params into a collection, right?

in fact that's probably already available

just a flat dictionary of values

and then use something like AgileMapper to map those onto the query object

do that in a base type

...this is all probably a horrible abuse of Minimal APIs

but if I can get it working then you can define a whole API like this

and then just write a load of handlers

(it uses MediatR under the hood)

Lari Tuomisto

@shinpou

any idea if I can somehow easily verify if model binding has occurred or not - I wish to verify that my uploaded files are actually being streamed without being loaded into memory

Taylor

@TaylorWatson

hi guys :)

If I have a URL as a string. Is there a way I can utilize the .Net's Query logic to automatically break up the parameters?
