@@smnomad9276 these days I'm less concerned about performance and more concerned about developer productivity and code maintainability - luckily Go provides both!

[@heldim92]

I am about to begin as well, still in doubt between Go and C#... Any insights?

[@orterves]

@heldim92 go wants to be simple - minimal hierarchy and interfaces, tests colocated with code, etc; c# wants to be formal - well-defined hierarchy with dependency injection, distinct test projects and separation of concerns. Both approaches can be productive and valuable; both approaches can be taken too far and cause issues. The right choice for any particular project comes down to business requirements, team knowledge and the deployment target and what features of the SDK and supporting ecosystem you have a need for. All that said, I think C# (especially now with .net 8) is fantastic - and yet my default these days for projects is Go.

Using Stdlib in teams still sucks. Conventions are important in teams. No one wants to read 20 different implementations of boilerplate functions

[@thisisreallyme3130]

Teams having uniform conventions and coding styles IS very important. But embracing abstractions isn't the most straightforward way to solve THAT problem. In any case, this is kind of a beginner tutorial and in THAT context it wouldn't be responsible to sidestep the std lib and just embrace framework du jour. I appreciate that in production code with large teams and churn, one needs to compromise and just use what "most" people use.

[@h4ckedneko]

The API is very similar to chi. It's like chi is now a part of the standard library, which is great. Although, it lacks centralized error handling like what in Fiber has managed to perfect.

[@TheQxY]

I hear this a lot, but I don't think it's such an issue. For small projects, centralised error handling is not really necessary. And for larger projects you can implement a middleware that wraps a handler func that returns an error, logs it, and returns an handler func that does not return an error in less than 10 lines of code.

[@h4ckedneko]

@@TheQxY That is what I do in our older projects that uses net/http + chi. I created my own custom handler signature which is close to http.Handler but it returns error. Then the wrapper will catch that error, logs it in Sentry if it's fatal, then creates an HTTP response for that error. Though once we migrated to Fiber, I never got to do all those boilerplates again because the handler signature in Fiber returns an error just like in my custom handler, and you only need to register an error handler function in the router for catching those errors, no more tedious wrapping. I agree that it's not necessary but it's convenient to have.

[@lutherwaves6929]

Thanks @dreamsofcode for the video, really well explained! I actually managed to translate my whole go chi project into stdlib upon updating to 1.22 with the help of your video! One thing that caught my eye was during the demonstration of sub-routing, the v1 mux was initialized, but then the http.Server definition below still receives router as the Handler, instead of the v1 router. This did not work for me. I am either misunderstanding how this works, or there might be something unclear/incorrect in the video. Note that I am new to Go net/http. Would appreciate your feedback on this, so we can make it clearer for everyone!

[@dreamsofcode]

This might be a simple editing mistake! You'll want to pass the v1 router as the handler to the server! Apologies for that!

8:18 one thing to note is that creating a wrapper for ResponseWriter like this may cause some issues and performance problems, because most ResponseWriter implementations also have methods that are not part of the interface (like http.Flusher, http.Pusher or http.Hijacker, used for WebSocket connections). If you want a battle-tested RW wrapper, you should take a look at the Chi router's WrapWriter middleware.

I simply use a switch statement to call the correct handler and use structures and their methods to pass middleware functionality. Like a structure with fields for a database connection and a custom logger. Then your handler method can just make calls to the structure's fields' methods.

I'm having a problem with the subrouting 10:45 The problem is that you cannot POST to "/" under the subrouter when you strip the prefix. The other routes work because there is no trailing slash, but suppose you want to POST to /v1 itself, there is no way to set up that route as far as I know. You can only set up /v1/ which is different, so http issues a redirect.

[@ahmedb.hameed3330]

I have also issues with subrouting. I thought it acts as a grouping but caused routes to return 301. Also not sure how to make multiple NewServeMux ? For me it does not work but I can't be so sure as I am a go noob.

[@ahmedb.hameed3330]

After long try and error, I managed it to work. Maybe that can help you. Note that nested subrouting can't be crouped in one string. I know it is stupid but at least can work like the example bellow by repeating few lines. route := http.NewServeMux() // Assets routes route.Handle("GET /css/", http.StripPrefix("/css/", http.FileServer(http.Dir("public/css")))) route.Handle("GET /js/", http.StripPrefix("/js/", http.FileServer(http.Dir("public/js")))) route.Handle("GET /images/", http.StripPrefix("/images/", http.FileServer(http.Dir("public/images")))) route.Handle("GET /audio/", http.StripPrefix("/audio/", http.FileServer(http.Dir("public/audio")))) // Pages API pageRoute := http.NewServeMux() pageRoute.HandleFunc("GET /", views.Home) pageRoute.HandleFunc("GET /auth/login", views.Login) pageRoute.HandleFunc("GET /live-reload", LiveReload.Run) // mux.HandleFunc("GET /*", views.Error500) // Public API route.HandleFunc("POST /register", AuthModule.SignUp) route.HandleFunc("POST /login", AuthModule.Login) route.HandleFunc("POST /verify-email", AuthModule.VerifyEmail) route.HandleFunc("GET /refresh-token", AuthModule.RefreshToken) route.HandleFunc("GET /logout", AuthModule.Logout) // Protected APIs route.HandleFunc("GET /me", middleware.Protected(AuthModule.Me)) route.HandleFunc("GET /admin/users", middleware.Protected(UserModule.ListUsers)) route.HandleFunc("GET /admin/users/{userId}", middleware.Protected(UserModule.GetUser)) route.HandleFunc("PUT /admin/users", middleware.Protected(UserModule.AdminUpdateUser)) mux := http.NewServeMux() mux.Handle("/", pageRoute) mux.Handle("/v1/", http.StripPrefix("/v1", route)) mux.Handle("/api/", http.StripPrefix("/api", mux)) // Register groups and routes // mux.RegisterGroups() APP_VERSION := services.Getenv("APP_VERSION") PORT := services.Getenv("SERVER_PORT") log.Printf(" \t✅ Server is listening to \t: localhost:%v \t✅ App version\t\t\t: %v ", PORT, APP_VERSION) http.ListenAndServe(":"+PORT, middlewareStack(mux))

9:00 why will a middleware have a status code? Status code is present when a response is returned, not during a middleware. 7:29 why is the import statement pointing to your GitHub if its included in the standard lib?

[@dreamsofcode]

1. Because you'll need access to the status code in order to log it out. 2. It's not pointing to my Github, that's the package path in the Go mod, it's a local dependency. The middleware package was created using standard library components.

[@anthonycavagne4880]

Hi ! Just one question here, why loop in inverse order in the create stack function ?

[@dreamsofcode]

Great question! This is so that the first element in the array acts as the top of the stack. The middleware isn't necessarily calling the next handler, more like wrapping each middleware inside. i.e. [a,b,c] needs to be a(b(c)) so it's easier to wrap it with a reverse iterator

[@MattRobinsonDev]

[@ashishgupta8394]

❤ amazing explanation

[@ehl-12]

Amazing video, thank you! I did have one question though: the `v1` subrouting is confusing me, because you do setup a new Muxer for it, but then you're not using that one as the handler to the `http.Server` -- it's still using the original `router`. Why does that work?

[@PanicAtProduction]

Basically, you wrote your own framework. Behind the scenes, 3rd party libraries do the same thing that you said maybe more efficient in terms of complexity. I check real world benchmarks, crud operations, caching, https routing etc before I start a project. I didn't care this before, but when we receive the invoice from AWS, we can easily see it matters and worth it. You can handle thousand of operations in a small vps with go. It is impossible to handle same operations with JS(express or koi) under the same conditions.

[@danielgospodinow]

11:13 - Can't/shouldn't we add this auth middleware not to `router` but to `adminRouter` instead? Since that way, we're adding admin-specific logic into the main router which doesn't seem ideal to me. And btw, fascinating content!

[@dreamsofcode]

It looks a little confusing, but basically we are doing that by wrapping the admin router only. It could have probably been explained a little easier if I added a /admin to that path!

[@samifouad]

@@dreamsofcode what’s confusing about it is that it seems like the admin router has not been activated. I can see where we are wrapping middleware on it, but it seems like it’s inactive … but it actually is. I think it could be made clear with a stack that merges routers, similar to the stack that merges middleware. that way it’s very obvious we are also initializing the admin router.

I keep liking the idea of paths without path variables using instead query parameters to pass any variable. The path becomes the name of a (sub) category of entities unpolluted of instance sourcing values. The query becomes the selector of the instance. Conceptually simpler IMO also method handlers specified at nested level avoid repetition because there is a one to many relationship between path and methods. Why not implementing middleware as a list of interfaces to be iterated over rather than nested calls?
