When I've encountered this, we've had to use another repo to keep scripts that managed this. But this was also sometimes problematic because each developer's setup had to be identical on their local file system (for the script to work) or we had to each create a config file pointing to where each repo lived.
This also impacts tracking down bugs and regression analysis; this is much easier to manage in a mono-repo setup because you can get everything at the same revision instead of managing synchronization of multiple repos to figure out where something broke.
Having a centralized configuration library (a shared Makefile that we can pull down into our repo and include into the local Makefile) helps, until you have to make a backwards-incompatible change to that Makefile and then post PRs to every branch of every repo that uses that Makefile.
Now we have almost the entirety of our projects back into one repository and everything is simpler; one PR per release branch, three PRs (typically) for any change that needs backporting. Vastly simpler process and much less room for error.
What instead, then? Explicit GitOps. Explicit, reified release specifications (think k8s resource manifests, or Erlang .relup files), one per separately-deploy-cadenced component. If you have a monorepo, then these live also as a dir in the monorepo. CD happens only when these files change.
With this approach, a single PR can atomically merge code and update one or more release specifications (triggering CD for those components), if and when that is a sensible thing to do. But there can also be separate PRs for updating the code vs. "integrating and deploying changes" to a component, if-and-when that is sensible.
How do you avoid the chicken-and-egg problem? Like if the k8s manifest contains a container tag, and the tag is created by CI when the PR is merged to main, it would seem you can’t add code and deploy that code in the same PR.
- PR creation (or any update to the PR branch by a human) would trigger a CI workflow to build+push the container;
- if this succeeds, the workflow would push a commit to the PR feature branch that pins the container ref;
- and the base branch would have a branch protection rule that makes the success of this CI workflow a prerequisite for PR mergeability.
In the explicit-GitOps-in-monorepo case, you'd probably want to do this by having the PR author modify the release spec file of each component they want to build a release for, replacing the old static ref with a temporary symbolic ref meaning "hey CI system, calculate this." Then the CI's added commit would rewrite those temporary symbolic refs into new static ones.
---
Although, that's all assuming that you even want to do CI builds in the first place. If you're developing containerized server software — rather than an operating system, a web browser, etc — then it shouldn't matter where you're building, and there isn't much impetus for deterministic, auditable builds, either. So why bottleneck builds by shoving them all onto some wimpy CI system—when every engineer already has a powerful workstation that can do builds often 4x faster, sitting there idle?
Here's what I call "local-first explicit GitOps":
1. you give your engineers the ability to push refs to the container registry (but you never use symbolic refs, always static manifest SHAs, so a malicious engineer can't do anything dangerous with this.
2. you add a script to your monorepo, that an engineer can run against their feature branch, that'll notice their current branch's local symbolic refs, and build+push containers locally in order to rewrite those into static refs.
3. On success, the script can use `gh` (or equivalent) to trigger PR creation.
Now every PR will come into existence already pinning valid new build artifacts by their static refs!
For example: build code and image, update git reference and version number in Application when build done.
You then get atomic updates of both code and configuration.
Even with a few services, we saw some pretty crunchy issues with people not understanding that service A had version 1.3.1234 of a module and Service B had version 1.3.1245 and that was enough skew to cause problems.
Distinct repos tend to have distinct builds, and sooner or later one of the ten you're building will glitch out and have to be run twice, or the trigger will fail and it won't build at all until the subsequent merge, and having numbers that are close results in a false sense of confidence.
Of course k8s not required, you can do it in straight IaC etc (i.e deploy a whole parallel system and switch).
It's still "mixed fleet" in terms of any shared external resources (queues, db state, etc) but you can change service interfaces etc with impunity and not worry about compatibility / versioning between services.
Throwing temporary compute at the problem can save a lot of busywork and/or thinking about integration problems.
This stops being practical if you get _very_ big but at that point you presumably have more money and engineers to throw at the problem.
Your software artifacts will have loose coupling if you divided them well enough on their creation. As soon as they are created, you can't do anything else to change it, except for joining or splitting them.
That is, if you’re not tied to using just Github of course.
Big monorepos and multiple repo solutions require some tooling to deal with scaling issues.
What surprises me is the attitude that monorepos are the right solution to these challenges. For some projects it makes sense yes, but it’s clear to me that we should have a solution that allows repositories to be composed/combined in elegant ways. Multi-repository pull requests should be a first class feature of any serious source code management system. If you start two projects separately and then later find out you need to combine their history and work with them as if they were one repository, you shouldn’t be forced to restructure the repositories.

Not in my experience. I use "git blame" all the time, and routinely read through commits from many years ago in order to understand why a particular method works the way it does.
Luckily, there are many tools for merging git repos into each other while preserving history. It's not as simple as copy and paste, but it's worth the extra efford.
Do you have examples of source code management systems that provide this feature and do you have experience with them? repo-centric approach of GitHub often feels limiting.
Same idea if you use some kind of versioning and release system. It's still a bit of a pain with all the PRs and coordination involved, but at every step every branch is consistent and buildable, you just check it out and hit build.
This is obviously more difficult if you have a more loosely coupled architecture like microservices. But that's self-inflicted pain
We went from monorepo to multi-repo at work and it's been a huge set back and disappointment with the devs because it's what our contractors recommended.
I've asked for a code deploy and everything and it's failed in prod due to a missing check in
> ...because it's what our contractors recommended
A startup I joined started with a multi-repo because the senior team came from a FAANG where this was common practice to have multiple services and a repo for each service.
Problem was that it was a startup with one team of 6 devs and each of the pieces was connected by REST APIs. So now any change to one service required deploying that service and pulling down the OpenAPI spec to regenerate client bindings. It was so clumsy and easy to make simple mistakes.
I refactored the whole thing in one weekend into a monorepo , collapsed the handful of services into one service, and we never looked back.
That refactoring and a later paper out of Google actually inspired me to write this article as a practical guide to building a "modular monolith": https://chrlschn.dev/blog/2024/01/a-practical-guide-to-modul...
If you just have 20-30 devs and everyone is pretty silo'd (e.g. frontend or backend, data or API, etc) having 75 repos for your stuff is just silly.
As someone who worked in the dev tooling org, getting teams to keep their deps up to date was a nightmare.
Then you are adapting your project to the properties of code repository. I don't see that as a benefit.
A github search for 'operator' in the openshift org has 178 results:
https://github.com/orgs/openshift/repositories?language=&q=o...
Not all are repos hosting one or more microservices, but most appear to be. Best of luck ensuring consistency and quality across so many repos.
Enforcing standards means actually having org level mandates around acceptable development standards, and it's enforced using tools. Those tools should be just as easily run on one monorepo than 50+ distributed repositories, nay?
If you wanted to, sure, applying enough time and money could make it work. I like to think that those resources might be better spent, though.
The difference is that past a certain level of complexity, the org will most certainly need specialized tooling to support massive codebases to make CI/CD (build, test, deploy, etc.) times sane.
On the other hand, multi-repos may work for massive orgs, but is always going to add friction for small orgs.
The point here is to understand what are the problems that are being solved, understand if they are similar to yours, and make a decision based on wether the tradeoffs are a good fit for you.
Not necessarily disagreeing with you but I just feel the pendulum on this statement has swung to far to the other side now.
Were they working with multiple services in a multi-repo? Seems like a cross-product explosion of repos. Did that configuration inhibit releases, or was the process cumbersome but just smooth because it was so rote?
So yeah, cumbersome, but established, and huge downside risk to messing with the status quo. It was basically Git applied on top of an existing “copy the source” release process.
Why? Is your framework heavily tied to client bindings? APIs I consume occasionally get new fields added to it for data I don't need. My code just ignores it. We also have a policy you cannot add a new mandatory field to API without version bump. So maybe REST API would have new field but I didn't send it and it happily didn't care.
Now, though, it seems the pendulum has swung in the opposite direction, from “everything in its own repo” to “everything in one repo.” This, too, will create its own set of problems, which also can be comedic, but frustrating to experience. For instance, what happens when someone accidentally pushes a certificate or API key and you need to force an update upstream? Coordinating that with 50 developers spread across 8 projects, all in a single repo.
Instead we could also face the problems we currently face and start out wirn a balanced approach. Start with one repository, or split frontend and backend if needed. For data pipelines that share models with the API, keep them in the same repository, creating a single source of truth for the data model. This method has often led to other developers telling me about the supposed benefits of “everything in its own repo.” Just as I pushed back then, I feel the need to push back now against the monorepo trend.
The same can be said for monoliths and microservices, where the middle ground is often overlooked in discussions about best practices.
They all reminded me of the concept of “no silver bullet”[0]. Any decision will face its own unique challenges. But silver bullet solution can create artificial challenges that are wasteful, painful, and most of all unnecessary.
The correct approach here is typically to invalidate the certificate or API key. A force push usually doesn't work.
If you're using GitHub, the dangerous commit lives on effectively forever in an awkward "not in a repository" state. Even if you're not on GitHub and your system actually garbage collects, the repo has been cloned onto enough build machines and dev machines that you're better off just treating the key or cert as compromised than trying to track down all the places where it might have been copied.
You’re correct about keys/certs once uploaded, they should be treated as compromised, especially when the repository isn’t self-hosted. However, replacing API keys and certificates can take time, and within a large corporation, it could take months.
Separate repos for each team means that when two teams own components that need to interact, they have to expose a "public" interface to the other team--which is the kind of disciplined engineering work that we should be striving for. The monorepo-alternative is that you solve it in the DMZ where it feels less like engineering and more like some kind of multiparty political endeavor where PR reviewers of dubious stakeholder status are using the exercise to further agendas which are unrelated to the feature except that it somehow proves them right about whatever architectural point is recently contentious.
Plus, it's always harder to remove something from the DMZ than to add it, so it's always growing and there's this sort of gravitational attractor which, eventually starts warping time such that PR's take longer to merge the closer they are to it.
Better to just do the "hard" work of maintaining versioned interfaces with documented compatibility (backed by tests). You can always decide to collapse your codebase into a black hole later--but once you start on that path you may never escape.
Neither a monorepo nor separate repos will result in people being disciplined. If you already have the discipline to do separate repositories correctly then you'll be fine with a monorepo.
So I guess it's six on one hand, half dozen in the other.
Dev's *like* to feel ownership of reasonably sized chunks of code. We like to arrange it in ways that is pleasing for us to work on later down the road. And once we've made those investments, we like to see them pay off by making quick easy changes that make users happy. Sharing a small codebase with three or four other people and finding ways to make each other's lives easier while supporting it is *fun* and it makes for better code too.
But it only stays fun if you have enough autonomy that you can really own it--you and your small team. Footguns introduced need to be pointed at your feet. Automation introduced needs to save you time. If you've got the preferences of 50 other people to consider, and you know that whatever you do you're going to piss off some 10 of them or another... the fun goes away.
This is simple:
> we own this whole repo and only this 10% of it (the public interface) needs to make external stakeholders happy, otherwise we just care about making each other happy.
...and it has no space in it for there to be any code which is not clearly owned by somebody. In a monorepo, there are plenty of places for that.
The meat is in the detail, I find.
I have solved more bugs looking at diffs in GitHub than I have in my debugger simply by having everything in one happy scrolly view. Being able to flick my mouse wheel a few clicks and confirm that the schema does indeed align with the new DTO model props has saved me countless hours. Confirming stuff like this across multiple repos & commits can encourage a more lackadaisical approach. This also dramatically simplifies things like ORM migrations, especially if you require that all branches rebase & pass tests before merging.
I agree with most of the hypothetical caveats, but if you can overcome them even with some mild degree of suffering, I don't see why you wouldn't fight for it.
Do you want hard boundaries between teams — clear responsibilities with formal ceremony across boundaries, but at the expense of living with inflexibility?
Do you want fluidity in engineering, without fixed silos and a flat org structure that encourages anyone to take on anything that’s important to the business right now, but with the much bigger overhead of needing strong people leaders capable of herding the chaos?
I’m sure there are dozens of other examples of org structures and how they are reflected in code layout, repo layout, shared directories, dropboxes, chat channels, and email groups etc.
In particular many build pipelines involving private sources or artifacts become drastically more complicated than their those of publicly available counterparts.
The Git team should really invest in tooling for very large repos. Our repo is around 10M files and 100M lines of code and no amount of hacks on top of Git (cache, sparse checkout etc etc) is not really solving the core problem.
Meta and Google have really solved this problem internally but there is no real open source solution that works for everyone out there.
Perforce is pretty brutal, and the code review tools are awful - but its still the undisputed king of mixed text and binary assets in a huge monorepo.
Microsoft released Scalar (https://github.com/microsoft/scalar) although it's not a complete stack yet but it is already planning on releasing the backend components eventually.
Have you tried Sapling? It has EdenFS baked in so it'll only materialize the files you touch and operations are fast because it has a filesystem watcher for activity so it doesn't need to do a lot of work to maintain a view of what has been invalidated.
But if you do it right, the advantage you get is that you get to pick which versions of your dependencies you use; while quite often you just want to use the latest, being able to pin is also very useful.
For C++ in particular, you need to express your dependencies in terms of source versions, and ensure all of the build artifacts you link together were built against the same source version of every transitive dependency and with the same flags. Failure to do that results in undefined behaviour, and indeed I have seen large organizations with unreliable builds as a manner of routine because of that.
The best way to achieve that is to just build the whole thing from source, with a content-addressable-store shared with the whole organization to transparently avoid building redundant things. Whether your source is in a single repo or spread over several doesn't matter so long as your tooling manages that for you and knows where to get things, but ultimately the right way to do modular is simply to synthesize the equivalent monorepo and build that. Sometimes there is the requirement that specific sources should have restricted access, which is often a reason why people avoid building from source, but that's easy to work around by building on remote agents.
Now for some reason there is no good open-source build system for C++, while Rust mostly got it right on the first try. Maybe it's because there are some C++ users still attached to the notion of manually managing ABI.
If you do one big monolithic deploy, one big monorepo is ideal. (Also, to be clear, this is separate from microservice vs monolithic app: your monolithic deploy can be made up of as many different applications/services/lambdas/databases as makes sense). You don't have to worry about cross-compatibility between parts of your code, because there's never a state where you can deploy something incompatible, because it all deploys at once. A single PR makes all the changes in one shot.
The other rule I have is that if you want to have individual repos with individual deployments, they must be both forward- and backwards-compatible for long enough that you never need to do a coordinated deploy (deploying two at once, where everything is broken in between). If you have to do coordinated deploys, you really have a monolith that's just masquerading as something more sophisticated, and you've given up the biggest benefits of both models (simplicity of mono, independence of multi).
Consider what happens with a monorepo with parts of it being deployed individually. You can't checkout any specific commit and mirror what's in production. You could make multiple copies of the repo, checkout a different commit on each one, then try to keep in mind which part of which commit is where -- but this is utterly confusing. If you have 5 deployments, you now have 4 copies of any given line of code on your system that are potentially wrong. It becomes very hard to not accidentally break compatibility.
TL;DR: Figure out your deployment strategy, then make your repository structure mirror that.
You can have a mono-repo and deploy different parts of the repo as different services.
You can have a mono-repo with a React SPA and a backend service in Go. If you fix some UI bug with a button in the React SPA, why would you also deploy the backend?
The gains provided by moving from polyrepo to monorepo are immense.
Developer access control is the only thing I can think to justify polyrepo.
I'm curious if and how others who see the advantages of monorepo have justified polyrepo in spite of that.
As always, complexity merely moves around when squeezed, and making commits/PRs easier means something else, somewhere else gets less easy.
It is something that can be made better of course, having your CI and CD be a bit smarter and more modular means you can now do selective builds based on what was actually changed, and selective releases based on what you actually want to release (not merely what was in the repo at a commit, or whatever was built).
But all of that needs to be constructed too, just merging some repos into one doesn't do that.
I linked an example below. Most CI/CD, like GitHub Actions[0], can easily be configured to trigger on changes for files in a specific path.
As a very basic starting point, you only need to set up simple rules to detect which monorepo roots changed.
[0] https://docs.github.com/en/actions/writing-workflows/workflo...
All you need to know is "does changing this code affect that code".
In the example I've given -- a React SPA and Go backend -- let's assume that there's a gRPC binding originating from the backend. How do we know that we also need to deploy the SPA? Updating the schema would cause generation of a new client + model in the SPA. Now you know that you need to deploy both and this can be done simply by detecting roots for modified files.
You can scale this. If that gRPC change affected some other web extension project, apply the same basic principle: detect that a file changed under this root -> trigger the workflow that rebuilds, tests, and deploys from this root.
Of course the multirepo approach means you do this dance a lot more: - Create a change with backwards compatibility and tombstones (e.g. logs for when backward compatibility is used) - Update upstream systems to the new change - Remove backwards compatibility and pray you don't have a low frequency upstream service interaction you didn't know about
While the dance can be a pain - it does follow a more iterative approach with reduced blast radiuses (albeit many more of them). But, all in all, an acceptable tradeoff.
Maybe if I had more familiarity in mature tooling around monorepos I might be more interested in them. But alas not a bridge I have crossed, or am pushed to do so just at the moment.
In my experience the article is right when it tells you there isn’t that big of a difference. We have all sorts of repositories, some of which are basically mono-repositories for their business domain. We tend to separate where it “makes sense” which for us means that it’s when what we put into repositories is completely separate from everything else. We used to have a lot of micro-repositories and it wasn’t that different to be honest. We grouped more of them together to make it easier for us to be DORA compliant in terms of the bureaucracy it adds to your documentation burden. Technically I hardly notice.
The basic way most work is to run full CI on every change. This quickly becomes a huge speedbump to deployment velocity until a solution for "only run what is affected" is found.
I don’t want to be rude, but a lot of these tools have rather accessible documentation on how to get up and running as well as extensive documentation for more complex challenges available in their official docs. Which is probably the, only, place you’ll find good ways of working with it because a lot of the search engine and LLM “solutions” will range from horrible to outdated.
It can be both slower and faster than micro-repositories in my experience, however, you’re right that it can indeed be a Cthulhu level speed bump if you do it wrong.
I'm not against only run what is affected, it is a good answer. It just has failings that you need to be aware of.
For example, in GitHub[0]:
name: ".NET - PR Unit Test"
on:
## Only execute these unit tests when a file in this directory changes.
pull_request:
branches: [main]
paths: [src/services/publishing/**.cs, src/tests/unit/**.cs]
[0] https://docs.github.com/en/actions/writing-workflows/workflo...
That is, the green check mark means "the changes in this commit did not break anything that was not already broken", as opposed to the more useful "the repository, as of this commit, passes all tests".
If you split something into multiple repositories then surely you wouldn't mark PRs on one of them as red just because tests are failing in a different one?
The meaning we give to "the commit is green" is not "this PR can be merged" but "this can be deployed to production", and it is used for the purpose of selecting a release candidate several times a week. It is a statement about the entire state of the project as of that commit, rather than just the changes introduced in that commit.
I can understand the frustration of creating a PR from a red commit on the main branch, and having that PR be red as well as a result. I can't say this has happened very often, though: red commits on the main branch are very rare, and new branches tend to be started right after a deployment, so it's overwhelmingly likely that the PR will be rooted at a green commit. When it does happen, the time it takes to push a fix (or a revert) to the main branch is usually much shorter than the time for a review of the PR, which means it is possible to rebase the PR on top of a green commit as part of the normal PR acceptance timeline.
In this article almost everything makes sense to me (because that's what I have been doing most of my career) but they put their OTP app inside which suddenly makes no sense. And you can see the problem in the CI they have dedicated files just for this App and probably very few common code with the rest.
IMO you should have one monorepo per project (api, frontend, backend, mobile, etc. as long as it's the same project) and if needed a dedicated repo for a shared library.
This is google3. It was absolutely loved by the majority of devs. If you change a line of code, all dependencies are type checked and tested and also a bunch of other things. It keeps so many versioning issues out.
One of the big reasons why the JS ecosystem is so fragmented compared to Go or even Rust is the leftpad-sized packages with 10 config files that are out of date. Not to mention our friend peerDependencies, who needs no introduction.
that's not a monorepo!
Unless the singular "project" is stuff our company ships, the problem you have is of impedance mismatch between the projects, which is the problem that an actual monorepo solves. for swe's on individual projects who will never have the problem of having to ship a commit on all the repos at the "same" time, yeah that seems fine, and for them it is. the problem comes as a distributed systems engineer where, for whatever reason, many or all the repos need to be shipped at the ~same time. or worse - A needs to ship before B which needs ship before C but that needs to ship before A, and you have to unwind that before actually being able to ship the change.
I'm not convinced that making completely different teams work on the same repo is making things better. In the case of cascading dependencies what usually works better than a convoluted technical solution is communication.
Sure it is! It's just not the ideal use case for a monorepo which is why people say they don't like monorepos.
They are literally saying that multiple repos should be used, also for sharing the code, this is not monorepo, these are different repos.
But it can also breed instability, as you can upgrade other people's stuff without them being aware.
There are ways around this, which involve having a local module store, and building with named versions. Very similar to a bunch of disparate repos, but without getting lost in github (github's discoverability was always far inferior to gitlab)
However it has its draw backs namely that people can hold out on older versions than you want to support.
This is why Google embraced the principle that if somebody breaks your code without breaking your tests, it's your fault for not writing better tests. (This is sometimes known as the Beyonce rule: if you liked it, you should have put a test on it.)
You need the ability to upgrade dependencies in a hands-off way even if you don't have a monorepo, though, because you need to be able to apply security updates without scheduling dev work every time. You shouldn't need a careful informed eye to tell if upgrades broke your code. You should be able to trust your tests.
I can think of only 2 ways that the multiple-branch monorepo is worse:
1. If the monorepo is large, everyone has to deal with a fat .git folder even if they have only checked out a branch with a few files.
2. Today, everyone expects different branches in a repo to contain "different versions of the same thing", not "a bunch of different things". But this is purely convention.
The only real benefit that I can see of making a separate repo (over adding a new project directory to a "classic" monorepo) is the lower barrier to getting underway -- you can just immediately start doing whatever you want; the pain of syncing repos comes later. But this is also true when starting work under a new branch in the branch-per-project style monorepo: you can just create a branch from the initial commit, and away you go -- and if you need to atomically make changes across projects, just merge their branches first!
What are the downsides I'm not seeing?
Neither one has an actual edge. Yet you can find countless articles from people talking about their experience. Take those as a hint about what kind of tooling you need, not about their comparative qualities.
Some core stuff into separate libraries, consumed as nuget packages by other projects. Those libraries and other standalone projects in separate repos.
Then a "monorepo" for our main product, where individual projects for integrations etc will reference non-nuget libraries directly.
That is, tightly coupled code goes into the monorepo, the rest in separate repos.
Haven't taken the plunge just yet tho, so not sure how well it'll actually work out.
So updating them at the same time shouldn't be a huge deal, we just make the change in the library, publish the nuget package, and then bump the version number in the downstream projects that need the change.
Ideally changes to these libraries should be relatively limited.
For things that are intertwined, like an API client alongside the API provider and more project-specific libraries, we'll keep those together in the same repo.
If this is what you're thinking of, I'd be interested in hearing more about your negative experiences with such a setup.
As soon as you add a second separate product that uses a different subset of any code in the repo, you should consider breaking up the monorepo. If the code is "a bunch of libraries" and "one or more end user products" it becomes even more imperative to consider breaking down stuff..
Having worked on monorepos where there are 30+ artifacts, multiple ongoing projects that each pull the monorepo in to different incompatible versions, and all of which have their own lifetime and their own release cycle - monorepo is the antithesis of a good idea.
I really don't see why anything you describe would be an issue at all for a monorepo.
We release everything weekly, and some things much more frequently.
If your testing is good enough, I don't see what the issue is?
Your testing isn't good enough. I don't know who you are, what you are working on, or how much testing you do, but I will state with confidence it isn't good enough.
It might be acceptable for your current needs, but you will have bugs that escape testing - often intentional as you can't stop forever to fix all known bugs. In turn that means if anything changes in your current needs you will run into issues.
> We release everything weekly, and some things much more frequently.
This is a negative to users. When you think you will release again next so who cares about bugs it means your users see more bugs. Sure it is nice that you don't have to break open years old code anymore, but if the new stuff doesn't have anything the user wants is this really a good thing?
1) Comparing a photo storage app to the Linux kernel doesn't make much sense. Just because a much bigger project in an entirely different (and more complex) domain uses monorepos, doesn't mean you should too.
2) What the hell is a monorepo? I feel dumb for asking the question, and I feel like I missed the boat on understanding it, because no one defines it anymore. Yet I feel like every mention of monorepo is highly dependent on the context the word is used in. Does it just mean a single version-controlled repository of code?
3) Can these issues with sync'ing repos be solved with better use of `git submodule`? It seems to be designed exactly for this purpose. The author says "submodules are irritating" a couple times, but doesn't explain what exactly is wrong with them. They seem like a great solution to me, but I also only recently started using them in a side project
Git submodules have some places where you can surprisingly lose branches/stashed changes.
Git submodules have some places where you can surprisingly lose branches/stashed changes.
Yeah- they idea is that all of your projects share a common repo. This has advantages and drawbacks. Google is most famous for this approach, although I think they technically have three now- one for Google, one for Android, and one for Chrome.
> They seem like a great solution to me
They don't work in a team context because they're extra steps that people don't do, basically. And did some reason a lot of people find them confusing.
