This approach is absolutely appropriate because it implements the paradigm of error handling at the source 👍

The next vid should be: A Beautiful Way To Deal With LOGGING in Golang

This is beautiful. The only thing i'd say you're missing is generating a request id per request so that if a bug report is filed either by a consumer or a user of the frontend, they can included that request id in their report and you can look up the log messages for their specific request(s).

I am learning a lot from this channel. You're giving a lot of experience for free. Thank you so much.

This is such an elegant organization. I'm sorry, I'm stealing this :) Your Make() function translates beautifully to Echo's HTTPErrorHandler callback. Very, very useful video. Thank you so much for this Anthony

You're the daddy of golang. Keep it GOing!! 💪💪💪💪💪

Even thought I'm not completely convinced with returning errors as a default, i see how this can be very clean, more so if you implement this useful error types.

Can you make an updated API series where you build a complete JSON api with the std library router with postgres and error handeling like this? That would be awesome

As a typescript / nextjs dev transitioning to Go, this is GOld. Cheers!

Is there any reason why you're not using `errors.As()` to check if your error is an ApiError?

The beauty of errors in golang is its open to different implementations. I always try to improve my handling and get new ideas. For now my take is the following. There are three type of errors I want to handle 1. User validation errors, or sql errors that are results of a query 2. Server errors that are expected (for example server is down) 3. Server errors that should not happen. For example Json marshal/unmarshal Which means my validation is wrong somewhere. The last 2 are internal server errors, which I want to bubble and wrap as they get to the handler, since it will create the path trace. I also might want to trigger some action (for example special log or email to the admin to handle it asap). The first one should have a fixed response for each error and will not wrap. So the error message from the origin of the error bubbles up intact. Of course there is a another issue to solve when the api is multilingual.

How can I access this code?

The Make() function is absolutely useful, but I wish you would name it differently.

I love your content and this new layout of videos where you just pick one topic and just keep the video short and concise is really good 🎉❤

What VSCode ext for Rest Api calls are you using?

Nice vid! I was working on this earlier today. Side note - some people have 2 letter names

5:38 we can check for err == nil and do early return I am new to programming but we can use Make(logger ,func) to pass in the logger to make this more useful ? depending that you are using custom logger and not using slog global value but can we change slog output destination anywhere? or we have to route os.Err stream to some file from linux

Is there a reason why you do not use the http.Error() function of net/http package? I use it like 'if err != nil {http.Error(w, responseErr.Message, responseErr.Status) return}'

This is the reason why I use Fiber instead of standard library or Gin.

Great video, thanks for share! I have one concern about return a message string sometimes and others an object, seems a little confuse. Could you comment about, please?

your ob'ekt instead of object sounds like ... a music to my russian ears ))

Hello! I've read in the docs of body for HTTP request that it's closed automatically by a server, so it's not necessary to call defer r.Body.Close() in any HTTP handler.

This is pretty clean

Great episode as usual, Just I have one concern what if you make the invalidJSON veridic func then u can throw away the InvalidJSONData and ur code will be very idiomatic

I do wonder why `defer r.Body.Close()` is after error check for JSON)) Won't it cause troubles?

which theme in vs code do you use? i am searching this theme veeeery long

Just curious how the request validation is done. Is it a custom implementation?

What happens if i dont close r.Body?

strange, I am doing this without having the handler throw an error. I guess its all about preference.

What is this "TC" file or something for sending requests? I see it for the first time, I am always using Postman to do these, but sometimes running one request for quick test inside VSC could be handy and I don't want to run "curl" :P

GOat

Just commenting to comment. This feels really convenient but not very go like. This ads a lot of inderection and unnecessary layers when the same functions could just write directly to the response writer. Which would be much simpler and clearer and do away with two or three unnecessary layers of inderection. But this is pretty much the same discussion for the 10th time on if handlers should returns errors our write to the response.

So what I currently do with the net/http library is use panic in controllers and recover it in a central error handling middleware. I can pass my custom error interface which the middleware can use to send data. Any problems with this approach?

Again we discover the wheel aye :P? Just use a framework do your job and that's all. Time is money you are not special, make it worthy.

is there real people that make money from Golang outside of back end jobs
