Since 1.22, the Go standard library now has everything we need to perform advanced routing without the need of a third party dependency. However, knowing how to perform tasks such as middleware, path parameters, subrouting and more can be difficult to know. So, in this video, we look at how to do advanced routing features in Go.

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.
Been learning go as my first proper language after c and java for my university degree. Go's a lot more fun.
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.
Welcome!
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)
Using Stdlib in teams still sucks. Conventions are important in teams. No one wants to read 20 different implementations of boilerplate functions
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.
Go 1.22 is such a blessing. And this video explains everything in such a clear and concise way, it definitely deserves more views and subscribers.
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.
As a long time C# Dev just now getting into Go, it seems I picked a very good time to get into Go.
Same here. Typescript developer
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!
I am about to begin as well, still in doubt between Go and C#...
Any insights?
@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.
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!
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.
Simply put, this is a masterpiece. Well done
Thank you! I'm glad you enjoyed it!

Damn I started learning golang 3 weeks ago and I already love it. Thank you for content!
Absolutely amazing!
You've been inspired me to try go
I really want to learn golang from you.
the way you teach and express is so intuitive and natural.
Please keep making more such videos
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.
Thank you! I'm glad you enjoyed it!
This certainly feels like the year of Go, and so I'll definitely be doing more content 😁
Awesome video. I used Chi and was very happy with it but now I will try standard net/http.
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.
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...
Porkbun is awesome, it's cool to see them sponsor videos like these!
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 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.
Man, this is so cool.
Thank you!
Top quality and clear explanations
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
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!
This might be a simple editing mistake! You'll want to pass the v1 router as the handler to the server! Apologies for that!
Thanks for clarifying! Imposter syndrome picked me up as it didn't work for me 😅
Keep up the good work - awesome video!
Top-notch information, thanks DoC
Thanks for your awesome content! Would you mind making a video about your distro setup ( I guess you are using Arch with some theming )
All I need now is for Go to add a way to know what StatusCode has been written by a middleware without having to wrap the ResponseWriter
Pretty cool stuff. I definitely need to upgrade my typing skills!
Most needed video right now for me ❤
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.
Love your content, great job!
1:55 I think you could argue that because the wildcard is farther down the path specification, that path 1 is more specific than path 2.
Nice video sir. I'm just learning golang, and this video is useful.
I would love to see a comparison with some framework. It's interesting if they are still really relevant.
i really do love the standard library of go
OMG, I learned a lot from this.
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
yes please, do a video on Certbot
Excellent vid always!
This is beautiful
Excellent Video. Lots of hand holding. I like it. However in spite of two cups of coffee in my system it felt "rushed" from a cadence perspective..
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;
thanks, man!
This video was 🔥🔥. Subscribing
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'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 dont want a CertBot vid, I want a LEGO (Letsencrypt-go) vid!
Useful, TX
Should a new router be run in the main gorutine or should it be run in a separate gorutine for max performance?
Your videos are really good, I put you up there with Fireship.
Keep it up.
I'm honored. The man is a legend.
@@dreamsofcode I found your channel because of Fireship channel. It's seems that people who follow Fireship also follow you so youtube suggested that to me as well. Nice channel.
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.
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?
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.
So weird hearing an Englishman pronounce "router" like the tool, or an American. (And "status", although many do, tbf.) Great videos though! And, about time, eh?! 👍👏
Haha, believe it or not I'm actually British/American.
I get the worst parts of both languages.
@@dreamsofcode relatable
lol @@dreamsofcode! You'd never know. You have a perfect "home-counties" accent. You could present the news for the BBC! Well, except for the American "router" pronunciation! They wouldn't have that! 😉😂
at 10:00, what can we do if there are multiple stacks?
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)
8:58 would be a nice PR
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
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.
very good video
I would pay for classes from this guy
You can super thanks the video, unless you're all talk of course
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.
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?
What about error handling?
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
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.
Need a video on http client like postman within the neovim
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 look, go is finally maturing to the level of all the web stacks that came before it....
Ball’s in Deno’s court now.
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!
Bro tell me how I opened PorkBun before his ad played.
Someone should make a standard template out of this that works like Laravel works with php
🎉🎉❤
Annoying thing is that you have to manually parse data from query params, form, path etc to be type safe unlike for example echo bind where you can just bind to struct.
had hard time finding how to override 404 page
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.
certbot video for sure
Middleware chaining 🎉
brb upgrading my side project to go 1.22 and migrating away from gin.
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?
Accept for handlers that return an error
I'm actually not a fan of handlers that return an error, personally! I know some people are though!
Amazing nothing to say
Dreams of code makes really good videos but as a frontend dev learning go, I gotta watch his vids on 0.75 speed...
:sob: I apologize.
I have a much slower paced video coming out tomorrow.
im shook go std lib doesn't expose statusCode without a wrapper like that for middleware. wut.
Why the methods are written as a string? Welcome to no auto-completion and typos and the whitespace thing! LOL
can I use porkbun if I'm muslim?
Idk, why are you Muslim?
second nice
Go is catching up to C# from a decade ago 😂
No, they still need to add 500 keywords to the language
The string definition of the required method is so garbage. It requires a single space after a string defined value? Wtf is this? 1995?
