moon vs turbo

[alexn-s]

i just found moon and it looks really promising with a ton of features.

currently i am using multiple monorepos with pnpm and turbo which works really well for me.
i am interested in how moon compares to turbo or lerna for example and what the experiences of other devs using moon are.

looking forward for moon to become the next monorepo manager 💖

Thanks for starting this. It's on my to do list, but definitely will require some deep investigative work. I would love to hear others thoughts on this matter.

I've never used Turborepo myself, so I can't compare at this time. The development of moon actually started before Turborepo was acquired by Vercel and released, so any similarities are coincidental. But in the grand scheme of things, a "build system" is typically a directed acyclic graph that is processed in topological order. The same could be said for Nx, Bazel, etc.

With that said, I have used Nx extensively, and plan on writing an in-depth comparison article in the future. Right now, we're trying to lock down the initial feature set for moon and stabilize it.

I've put together this comparison doc: https://moonrepo.dev/docs/comparison It's very high-level, but a good place to start. I will get more in-depth in the future once I've had time to investigate things further.

Thanks for comparing, looking great.

Maybe adding an entry to https://monorepo.tools would be an option: https://github.com/nrwl/monorepo.tools

[milesj]

@jase88 Yeah it's on my to do also! It's a great resource.

Finally got around to writing this: https://moonrepo.dev/docs/comparison#turborepo

Hi @milesj, I have two question about moon vs nx comparison. Can moon now or in the future:

• extend the graph with deps from another language like java via gradle or maven
• add a dynamic output for a task, for example for maven the output for a build is:{m2RepoPath}/{projectGroupId}/{projectName}/{projectVersion}

Both this features are covered by nx with createNodes and createDependencies functions.
Thanks

Hey 👋

extend the graph with deps from another language like java via gradle or maven

Do you have an example of what this looks like exactly?

add a dynamic output for a task

In the next release, outputs can be defined using token vars & env vars. That's the extent of the dynamic support at the moment.

I am referring to this Extending the Project Graph of Nx.
I made a plugin for maven, the idea was to parse pom.xml files and complete the graph with maven projects. Was asking if we can do the same with Moon.

[milesj]

At this time, there is not.

We plan to support toolchain plugins hopefully by EOY. This will allow users to create their own "go", "ruby", "zig", etc integration.

We also plan to update extension plugins (https://moonrepo.dev/docs/guides/extensions) in the future, to do just that, extend things. Right now they are very basic.
