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.

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)

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.

@IllllIIllllI Місяць тому

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.

@h4ckedneko Місяць тому

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 18 днів тому

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 18 днів тому

@@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.

@heldim92 День тому

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

@orterves День тому

@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.

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 Місяць тому

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

@iwolfman37 Місяць тому

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.

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.

@PanicAtProduction Місяць тому

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.

@dreamsofcode Місяць тому

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 ?

@dreamsofcode Місяць тому

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.
