turborepo VS go

GitHub: vercel/turborepo

When you setup a monorepo using turbo, the basic template gives you 3 packages by default. This can be found in turborepo/examples/basic.

Next, let’s create monorepo with Turborepo.

> Look at the dependency tree for a next

Looks ok to me: https://npmgraph.js.org/?q=next

Ironically, most of the dependencies are actually Rust crates used by swc and turbopack [1]. Try running cargo tree on either of those crates, it's enlightening to say the least. And of course, Node has a built in file watcher, and even the most popular third party package for file watching (Chokidar) has a single dependency [3].

Turborepo: Smart build system for JavaScript/TypeScript monorepos

We’ve only scratched the surface of what we can do with Turborepo. You can find more examples in the Turborepo examples directory on GitHub. Skill Recordings on GitHub is also another great resource that has been around since Turborepo was first released.

git clone https://github.com/vercel/turborepo.git

I use https://turborepo.org/ to facilitate my monorepo. Essentially it's a way of structuring your configs, UI; apps etc and you consume each like an internal package. I find benefits for this as the kinds of sites I make will generally have an internal app, an admin panel and a marketing site. I can write UI, config etc in one place and consume them over the three projects to keep everything consistent.

The latest addition to the Composer Suite monorepo, Turborepo optimizes monorepo workflows by caching build artifacts. This may sound a little abstract and boring, but what this actually means is that when you build something within your monorepo, Turborepo will make sure only the things that it depends on are rebuilt; everything else will be retrieved from a cache that either lives on your local computer, or a remote cache server. Adding Turborepo to the Composer Suite monorepo pretty much halved CI build times, but it was also a way to teach Vercel, which I use for hosting the various example apps in the repo, to only actually deploy the ones that have changed since their last deployment. And that's really cool!

> I didn't realize how important order was to type inference.

I was unclear, I'm afraid. You can reorder the type parameters, it just changes which of them you need to specify: https://go.dev/play/p/oDIFl3fZiPl

The point is that you can only leave off elements from the end of the list, to have them automatically inferred.

> Are there any real packages out there using these techniques?

I think so far, the usage of generics for containers in Go is still relatively sparse, in public code. I think in part that is because the documentation of how to do that is relatively sparse. That is part of the motivation for the post, to have a bit of somewhat official documentation for these things, so they become more widely known.

The standard library is just starting to add generic containers: https://github.com/golang/go/issues/69559 And part of that is discussing how we want to do things like this: https://github.com/golang/go/issues/70471

That being said, I have used the pointer receiver thing in my dayjob. One example is protobuf. We have a generic helper to set a protobuf enum from the environment. Because of how the API was designed, that required a pointer receiver constraint.

Source code for sync.Cond.Wait() (Go standard library) https://github.com/golang/go/blob/master/src/sync/cond.go For those who want to go under the hood and see how Wait() really works internally (with runtime_notifyListWait).

> Lack of proper enums is hurting so much I can't describe it.

Do you mean sum types? Its enums function just pretty much like enums in every single other language under the sun. If anything, Go enums are more advanced than most languages, allowing things like bit shifts. But at the heart of it all, it's all just the same. Here are enum implementations in both Go and Rust:

[Go] https://github.com/golang/go/blob/f18d046568496dd331657df4ba...

[Rust] https://github.com/rust-lang/rust/blob/40daf23eeb711dadf140b...

While Go leans on the enumerator value produced by `range`, while Rust performs explicit incrementing, the outcome is no different — just plain [n=0, n++].

This is one of the many things where Go just takes care of automatically. Since Go 1.19, if you import the os package, on startup, the open file soft limit will be raised to the hard limit: https://github.com/golang/go/commit/8427429c592588af8c49522c...

For a deeper dive, check out the source code for sync.Cond.

> But is know that the current way of Go (that is a insignificant improvement over the C way) sucks and ANY of the other ways are truly better […]

This is a bold statement for something so subjective. I'll note that the proposal to leave the status quo as-is is probably one of the most favorably voted Go proposals of all time: https://github.com/golang/go/issues/32825

Go language design is not a popularity contest or democracy (if nothing else because it is not clear who would get a vote). But you won't find any other proposal with thousands of emoji votes, 90% of which are in favor.

I get the criticism and I agree with it to a degree. But boldly stating that criticism as objective and universal is uninformed.
