I can't explain just how good the quality of this video is. The Go team should just point to this video for anyone who needs to know about these routing patterns.
Go really is a lot of fun! I think it's simplicity and the power of the standard library help to make it so. You get to spend more time building and less time fighting the compiler or re implementing things.
@@dreamsofcode I'm just glad I'm not doing extremely verbose object oriented stuff like I did in java. Oh and Go basically feels like c on steroids. The decision to not include header files in Go is awesome, coming from c.
You'll be very surprised how simple and straightforward the language is for the kind of performance it offers. That is why Go is called a "boring language" lol.
@@smnomad9276 these days I'm less concerned about performance and more concerned about developer productivity and code maintainability - luckily Go provides both!
@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.
Thank you! I had the most annoying discussions with people who were like: "net/http has no middlewares we need to adopt a framework and 15 fancy libs bla bla". In the future ill just link this video & tell em to learn the basics (because I still don't feel like dealing with them in a overly constructive way)
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.
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.
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.
@@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.
Coming from PHP & Laravel and just started playing around with Go 2 weeks ago and now I have this sweet video landed on my recommendation. I am so happy, I will stick to making quality Go + std lib videos in the future. Thank you, subbed!
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, could you please pin your response to this comment! I was following along with the video and ran into this also, it makes sense that we should pass v1 router instead of the original, but I wasn't sure if there was some fancy go magic that was supposed to be happening here Thank you for the amazing video!
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.
Thanks for the awesome content. Your videos are short but packed with valuable knowledge, which is more helpful than lengthy courses. Would love to see more Go programming videos from you.
The biggest reason I still use Echo, is for the middlewares they have available, especially for security, i don't need to write them or search for third party middlewares one by one I'm new to Golang, maybe there is a good pkg that handles all the security things i need, especially when using HTMX, security is very important since it's server side sending html
This was such an incredible wealth of information and it came at just the right time for me haha. Keep up the quality work!! This channel is slowly becoming invaluable to me as I'm learning Go.
Given the (excellent!) quality of this video I was hoping your channel was a Go focused channel teaching all the good design patterns to be used in Go. It would be SO valuable!!
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.
great video! quick tip: you can use a custom type as a key on context, this way there is no risk (due to type safety) of other packages accessing or overwriting your value
I think this is a really good video. I started using Gin for my current project that I'm working on. I only did this because it had clear documentation on how to test. Maybe if there were a video on how I could write tests for this stuff, I would definitely choose the standard library for the next project.
It seems a bit odd to download a private key… I'd rather generate one locally and request it to be signed. But then again, the goal here is simplicity I guess.
as the std library extends, other frameworks / library will slowly die.. though I think it's natural.. Great content. it makes me want to have another try with go
I'm learning Golang and creating some SSR website to apply it, and you literally covered every question I had. I was just done writing logging middleware when I was wondering how to pass information (request id and context to sqlc) downstream...
Thank you for the feedback! It's tough to balance between keeping it engaging and concise whilst also ensuring it's understandable. I'll aim to do better in future;
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?
I am a few months late on this comment but, a tutorial for a complete backend of a simple twitter-type app using only the standard library would be awesome. I'd love to see how you would expand the examples here even further to include database connections and even some testing.
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.
I appreciate the new visuals, they are pretty.cool, buy the stream of short phrases with filling space cut out feels like a Fireship video and I had trouble following it.
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.
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.
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("

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?
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.
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?
11:22 it runs the middleware but it still creates the invoice. Is this just because you didn't actually implement auth for the demo, or what's going on there?
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
The trick with wrapping the ReponseWriter to get the statusCode fails with stackoverflow if using the "/v1" Handle func that strips the prefix. Try that scenario with /v1/ and without in the path and you'll see the app crashing.
Hmm, I just tested this and couldn't get it to crash. http.StripPrefix only affects the request, not the response. If you're on discord (or anywhere else), mind sharing your code with me so I can take a look?
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!
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!
@@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.
Hi. If I have to implement a monthly or yearly subscription model for my mobile application. Then is it mandatory to use In-App-Purchases ? I mean we cannot use an external payment gateway. How Netflix is redirecting users to its website to avoid 30% fees. Please talk about this.
Gin does provide a lot of helper functionality to do things with less lines of code, but for me it breaks the contract with the standard library, so I prefer net/http.
idk the font or the theme but a theme that is similar is tokyonight. the editor is neovim. Unfortunately there are probably a thousand themes and dozens that are similar lol

I don’t think most of the established routers and such provide enough now to use over the std library for the most part. I really like Huma for APIs since it’s giving you OpenAI for free which I think is worth it for sure.
Hey Dreams of Code and other fellas, i am confident with express node and am thinking of learning a new backend lang but am pretty torn atm between golang and rust , could you suggest me or guide me here? it would really help me. Thanks and cheers 🍻🍻
I think it depends what you're looking for. Go is probably one of the best technologies to learn if you're interested in primarily building web applications, server side, infra and MPAs On the other hand, if you want more systems level programming, Rust will take you further. But Rust is much more challenging to learn and use than Go.

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

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!
@@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 ended up making a function that merges routers, works like a charm. clarifies that section much more so future me isn’t confused. 😄
Should a new router be run in the main gorutine or should it be run in a separate gorutine for max performance?
at 10:00, what can we do if there are multiple stacks?

"If you do it like this, your code will start to look like lisp, so instead..." proceeds to implement a damn trampoline.
Man, this is so cool.
Thank you!
Nice video sir. I'm just learning golang, and this video is useful.
8:58 would be a nice PR
I appreciate this soooo so much. a wonderful video. Told me just enough to run with it.
Glad to hear it!
Please make a video on certbot.
I really want to see a full Microservices code in go from scratch to production. Please make it happen.
I am working on a course looking exactly at this!
@@dreamsofcode i would be really really happy. Your contents are out of the world.
Dream how to I get to use my terminal with those numbers 1.Nvim, 2.Proyect, I’m using I term on Mac and using nvim as my editor also
A question, Is the `net/http` package in Go 1.22 fully capable of replacing the Gin framework?
It is
Most needed video right now for me ❤
Hi. If I have to implement a monthly or yearly subscription model for my mobile application. Then is it mandatory to use In-App-Purchases ? I mean we cannot use an external payment gateway. How Netflix is redirecting users to its website to avoid 30% fees. Please talk about this.
Which OS do you use? Could you also share your config for nvim, terminal?
@dreamsofcode
Given the updates of net package, is the framework like gin still necessary for some good reason?
Gin does provide a lot of helper functionality to do things with less lines of code, but for me it breaks the contract with the standard library, so I prefer net/http.
Question: Is there a framework for GO that is like svelt? Or svelte like?
The closest thing would be Templ, but it's still rendered on the server rather than rendered on the client.
hey look, go is finally maturing to the level of all the web stacks that came before it....
What is that color theme and font family? I need it.
idk the font or the theme but a theme that is similar is tokyonight. the editor is neovim. Unfortunately there are probably a thousand themes and dozens that are similar lol
brb upgrading my side project to go 1.22 and migrating away from gin.
I would pay for classes from this guy
You can super thanks the video, unless you're all talk of course
Does the other libraries like, echo, go, chi, mux use net/http, or are they all a complete reimplementation of http in go?
Some use a lot of the net/http package underneath. I believe chi has it's own router implementation internally.
Hey, which mic are you using? I loved the sound quality
Thank you! I use the Sennheiser MKH 50. It's a really great mic but not cheap.
Great video! Thanks!
Can you please make a video with certbot and http2 (can I also ask how to make my nvim chad theme to have more keywords highlighted)
Ball’s in Deno’s court now.
Excellent vid always!
Love your content, great job!
❤ amazing explanation
What about error handling?
any one know what font and theme are used on this video?
idk the font or the theme but a theme that is similar is tokyonight. the editor is neovim. Unfortunately there are probably a thousand themes and dozens that are similar lol
Bro tell me how I opened PorkBun before his ad played.
This is beautiful
OMG, I learned a lot from this.
This video was 🔥🔥. Subscribing
didnt quite get - first we write statusOk , but then we read different statusCodes in wrapped
Correct, the next handler in the chain will either modify the status code if there was a different one to 200.
I don’t think most of the established routers and such provide enough now to use over the std library for the most part. I really like Huma for APIs since it’s giving you OpenAI for free which I think is worth it for sure.
What's Huma?
thanks, man!
Hey Dreams of Code and other fellas, i am confident with express node and am thinking of learning a new backend lang but am pretty torn atm between golang and rust , could you suggest me or guide me here? it would really help me. Thanks and cheers 🍻🍻
I think it depends what you're looking for.
Go is probably one of the best technologies to learn if you're interested in primarily building web applications, server side, infra and MPAs
On the other hand, if you want more systems level programming, Rust will take you further. But Rust is much more challenging to learn and use than Go.
