Hey! In case you missed it, Turborepo launched 1.0 a few months ago[1].

This 1.2 release is important, as it includes --filter[2] (highly requested). You're able to much more easily filter tasks, instead of the previous --scope, --include-dependencies, --since, and --no-deps flags.

Happy to answer any questions about Turborepo or monorepos in general (recently wrote an entire post about them[3]).

any way you're going to solve the linting problem? I had having to install eslint and produce a config on every little package in my repository.

Yes I can use a generator to handle this and other boilerplate, but why? Can't turbo just spawn eslint in sub processes to lint each package and stitch the input back together?

leerob7• 4 years ago

If I'm hearing you correctly, your pain is having to configure ESLint manually, correct? Are you wishing for ESLint to be included in Turborepo natively? My opinion is that giving folks the option on their linter of choice is a good thing, even though ESLint is very popular.

Hello! We are using pnpm (which as I understand it has some overlap with what turborepo can do when it comes to monorepo management).

Some teams are considering turborepo for the remote caching feature. I'm a security guy, and I'm a little worried that remote caching basically means that all dev are able to run arbitrary code on other devs computer (by poising the cache). Am I missing something? Or are there security workarounds? Would, for example, only allow master build from the CI to push to the remote cache and only read only access for the devs work and still provide enough benefits? (I expect most dev to branch from master, so I'd assume the cache would be good enough?)

Thanks and congrats on the release!

Hey! Yeah, we recommend using pnpm. Excellent tool. You might be interested in this feature from 1.2:

"You can enable Turborepo to sign artifacts with a secret key before uploading them to the Remote Cache. Turborepo uses HMAC-SHA256 signatures on artifacts using a secret key you provide. Turborepo will verify the remote cache artifacts' integrity and authenticity when they're downloaded. Any artifacts that fail to verify will be ignored and treated as a cache miss by Turborepo"

Turborepo is a high-performance build system for JavaScript and TypeScript codebases.
Vercel, the well-funded front-end development platform from the team behind Next.js, today announced that it has acquired Turborepo, a high-performance build system for JavaScript and TypeScript monorepos, an increasingly popular way for organizing source code into a single repository that includes all of the necessary packages to build an application.

galaxyLogic• 4 years ago

What does it mean that Vercel has "acquired" Turborepo?

Isn't Turborepo open source? How do you acquire open-source?

bzxcvbn• 4 years ago

How do you acquire open-source?

You buy the company that develops it (or the main fork at least) and provides support for it.

tough• 4 years ago

Im pretty sure the acquisition was mentioned already a few months back

jvolkman• 4 years ago

The main page says it's for JavaScript and TypeScript codebases. Will it support other languages?

Fiahil• 4 years ago

Probably not, or it would become a Make competitor

tazjin3• 4 years ago

Your best bet for monorepo building across a variety of languages is Nix. If money is no object you can also make do with Bazel.

bamazizi• 4 years ago

Curious as to why "if money is no object" regarding Bazel? Where are the hidden costs? Appreciate it if you could elaborate

I haven't used it before but i'm considering Bazel, Please.Build or Nix for our monorepo.

leerob7• 4 years ago

From what I've seen, Nix[1] is exciting and has some innovative ideas, some of which we're learning from with Turborepo. I believe Replit uses it[2].

infamouscow• 4 years ago

I think you can benefit from using Nix and Bazel together.[1]

lhorie3• 4 years ago

From what I've seen, the scope of this project is to compete directly against the likes of Rush and Lerna. I spoke to the creator last year and my impression was that general language support akin to Bazel's was not a primary/immediate goal.

leerob7• 4 years ago

We're discussing more native support for other languages. It would likely be a commitment to a small subset of popular languages (e.g. Rust, Go, C++, Python) while still maintaining our goal of nearly zero configuration.

Well done and congrats to the Turborepo team on the launch as well as the Vercel merger, which I think is a great thing for the JS ecosystem!

We now have a healthy competition between several JS domain-specific build tools bit.dev, Nx, Turborepo, and Rush. This is in addition to plugins to general purpose monorepo tooling like rules_nodejs (Bazel). I'm looking forward to the seeing the new ideas that come out from the community as this field matures.

However, I feel a bit sad at the state of general purpose build tools (Bazel/Pants/Buck, make, GitHub Actions, Maven, Nix) or cloud-based IDEs (Cloud9, Codespaces). These tools come off as too complex to operate and build on top of such that we, the JS community, seem to be choosing to build JS-specific tooling from scratch instead. There are a huge number of mostly non-JS-specific problems that monorepo tooling eventually needs to solve: distributed build artifact and test result caching, distributed action execution, sandboxing, resource management and queuing, observability, and integration with other CI tools to name a few. I wish somehow we could reorganize around a smaller set of primitives instead of what appears to be reinventing the wheel.

Regardless, I think all of this effort and attention has lent credence to the monorepo thesis, and I'm very excited to see what's next.

Turborepo author/founder here....

I agree. I built Turborepo because existing tools weren’t meeting our needs.

To solve these problems and still be flexible, many existing build tools end up with lots of configuration bloat. We’re trying to avoid that. We want to reimagine the developer experience of monorepo tooling and make it accessible for everyone.

dfabulich• 4 years ago

Is it possible to integrate Turborepo with general-purpose monorepo build tools? Bazel, in particular?

(Is Bazel designed in a way that make it impossible to do JS monorepos well?)

pleasegod123• 4 years ago

Hey. Off topic but would you consider handing Formik and TSDX to a community member? Huge appreciation for turborepo and your work on these other libraries -- they have become key parts of the ecosystem and turborepo could follow.

However, this is all the more reason why it could be super helpful to address the governance issue on those projects. Thanks and sorry for disturbing!

qbasic_forever4• 4 years ago

I'm sad JS needs a build step. The best build system is none at all IMHO. I'd love to see native support everywhere for typescript or other things we typically depend on a build for today.

krapp3• 4 years ago

Good news: JS doesn't need a build step. Modern webdev wants a build step mostly because it wants Javascript to feel more like a "serious" language. There are technical benefits to compiling to Javascript, most of which can be served by other means, but the unnecessary complexity of the Javascript ecosystem is mostly about gatekeeping and aesthetics and i will die on that hill.

I'd love to see native support everywhere for typescript or other things we typically depend on a build for today.

Typescript is part of the problem. You can literally just accept Javascript for what it is - dynamically typed - and write it like any other scripting language.

This (controversial) feature is currently at stage 1 in TC39.

I definitely agree, although I've found Please (please.build) to potentially be a solution in this area. It is a lot simpler, smaller, and more modern than Buck and Bazel, but shares similar properties as to be familiar (I.e. the buildfile syntax). I think it is supposed to be easier to extend with other languages, but I haven't tries that myself.

andrew_• 4 years ago

bare-metal pnpm (what Rush is built upon) has never let me down. Handles rather large monorepos without issue.

darepublic• 4 years ago

I like github actions better than learning a new monorepo framework

bastardoperator• 4 years ago

I'm working with some fairly large monorepos and compile times. To be completely honest, JS is the least of our concerns when it comes to build time, things are pretty snappy when compared to other code bases like C, and Java even with tools like Bazel.

leerob7• 4 years ago

While we're initially focused on JavaScript and TypeScript codebases, you can already use Turborepo with any language as long as you define tasks through `package.json` scripts and use npm/pnpm/yarn workspaces. Turborepo is written in Go and uses `turbo` to build `turbo` in its own monorepo[1].

rattray• 4 years ago

This was my hunch, but it'd be awesome to make that a little more clear on the homepage! Especially if you can link to an FAQ with more detail on the tradeoffs.

When considering adopting a tool like this vs something more general-purpose like Bazel, I'd like to have a rough idea of how screwed I'll be when some non-JS/TS code gets added in the future.

wdb• 4 years ago

Please consider .net / msbuild support too :)

hiimshort• 4 years ago

Turborepo has been a welcome addition to the JavaScript tooling sphere.

Funnily enough, at nearly the same time as the initial version of Turbo became available, I had just about finished building my own monorepo tool for similar reasons (contemporary tools' inadequacies, etc). Haven't had a reason to switch personally, but I'm glad there are finally fast, small tools with good defaults (and minimal required configuration if any).

renke12• 4 years ago

Turborepo is really good, but there are a few things I like to see implemented:

* tasks on the root package (e.g. tsc -b that typechecks all packages)

* treat tasks such as lint:eslint, lint:pretter as a single task lint (or maybe lint:*)

These are probably niche features though.

palmdeezy3• 4 years ago

Turborepo author here...

* tasks on the root package (e.g. tsc -b that typechecks all packages)

We are working on this as we speak! The first step is to add the ability to restrict hashing `inputs`[1] to the Turborepo `pipeline`. After that we are going to be adding root task running in the next minor release.

However, as your monorepo grows, you will likely want to move away from running tasks like tsc from the root and instead run them on a per-package basis. The reason is that tools like Bazel, Buck, Turborepo, etc. can become more incremental (and thus faster) as your dependency/task graph becomes more granular (as long as you maintain or reduce the average affected blast radius of a given change). The other argument against root tasks is that they break hermeticity and encapsulation of the package abstraction. That being said, root tasks are very useful for fast migration to Turborepo and also for smaller repos. Futhermore, we're happy to tradeoff academic purity for productivity with features like this.

treat tasks such as lint:eslint, lint:pretter as a single task lint (or maybe `lint:*`)

You can run multiple tasks at the same time and Turborepo will efficiently schedule them at max concurrency.

turbo run eslint prettier --filter=@acme/...

However, it sounds like you like to see glob fan out of tasks. This is a really cool idea. I created a GitHub issue for it here [2] if you'd like to follow along.

renke12• 4 years ago

Perfect!

However, it sounds like you like to see glob fan out of tasks.

Yes, the idea here being that I don't want to list all similar tasks (such as linting) explicitly in the turborepo config. Teams should be free to add any additional lint task if they think it's useful for them (and possibly only for them). Similar to Maven(Java) where additional goals can be bound to the standard lifecycle phases.

no_wizard3• 4 years ago

Is there anything in the works to make this more feature fleshed like `nx` with plugins?

`nx` had alot of potential, but it falls really really short for non happy path projects when I tried integrating (this is as of 15 days ago) into a relatively simple monorepo. I really disagree with its plugin interface and the idea of separating your tests from your src folders (I don't want to litter a folder `e2e` every time I need to write some tests, just feels wrong. I also then have to publicly export certain things for testing if I'm doing it right)

In particular, I feel like using go templates to do something like `plop` does would be super nice.

wanderr• 4 years ago

Am I in the minority in thinking that we should stop trying to optimize for huge monorepos? The problems created by them seem far worse and more expensive than the problems they purportedly solve.

slively• 4 years ago

I’ve been wanting something like this but there’s a few big things that stick out to me. Why is it configured via json instead of scripting? Declarative task/build tools are just not as nice as something where you can write code. Specifying a task input/output seems very limited and is where so much optimization comes from. The remote cache seems to only be available through some hosted service?

I use Gradle a lot (bazel a little) and would love a tool that’s got an api that’s easier to understand, but this seems like 100 steps backwards without a good path forward.

leerob7• 4 years ago

You can self-host your remote cache if you'd like. For example, with GitHub Actions. We're working on better docs for this.
