The core code for both the Fluid client packages _and_ the reference ordering service is contained within this repo.
The repo structure is somewhat unique because it contains two monorepos as well as several standalone packages. The
The repo structure is somewhat unique because it contains five monorepos as well as several standalone packages. The
monorepos are managed using [Lerna](https://lerna.js.org/) and are versioned separately from one another, but internally
all packages in a monorepo are versioned together. Outside the monorepos there are plenty of packages which are
versioned independently.
Here's the breakdown of the repo:
These monorepos (which also serve as "release groups") do not necessary align with package namespaces,
and also don't necessary correspond to a single directory of this repo.
* Fluid Framework Client Monorepo ([lerna.json](./lerna.json))
* [Packages](./packages)
* [Fluid Examples](./examples)
* Azure-related Monorepo ([dir](./azure) | [lerna.json](azure/lerna.json)
* [Packages](./azure/packages)
* Reference Fluid Ordering Service ("Routerlicious") Monorepo ([dir](./server/routerlicious) | [lerna.json](server/routerlicious/lerna.json))
* [Packages](./server/routerlicious/packages)
* Common Packages
* [Common Definitions](./common/lib/common-definitions)
* [Common Utils](./common/lib/common-utils)
* Auxiliary Microservice Packages (supporting Routerlicious)
* [Server dir](./server) (excluding [Routerlicious](./server/routerlicious) itself)
* Internal/Misc Packages
* [Build Common](./common/build/build-common)
* [ESlint Config](./common/build/eslint-config-fluid)
* [Docs](./docs)
* [Tools](./tools)
Here's the list of Lerna managed release groups:
- core (previously known as "Fluid Framework Client" or "Client") (Rooted in [./](./). Configured by [./lerna.json](./lerna.json))
- [./packages](./packages) (Published in the `@fluidframework/` namespace, but some in `@fluid-tools` and unpublished packages in `@fluid-internal/`)
- [./experimental](./experimental) (Published in the `@fluid-experimental/` namespace)
- [./examples](./examples) (Not published, live in the `@fluid-example/` namespace)
- azure (Rooted in [./azure](./azure). Configured by [azure/lerna.json](azure/lerna.json))
- [Packages](./azure/packages) (Published in the `@fluidframework/` namespace)
- routerlicious (Reference Fluid Ordering Service) (Rooted in [./server/routerlicious](./server/routerlicious). Configured by [./server/routerlicious/lerna.json](server/routerlicious/lerna.json))
- [Packages](./server/routerlicious/packages) (Published in the `@fluidframework/` namespace)
- gitrest (Rooted in [./server/gitrest](./server/gitrest). Configured by [./server/gitrest/lerna.json](./server/gitrest/lerna.json))
- [Packages](./server/gitrest/packages) (Published in the `@fluidframework/` namespace)
- historian (Rooted in [./server/historian](./server/historian). Configured by [./server/historian/lerna.json](./server/historian/lerna.json))
- [Packages](./server/historian/packages) (Published in the `@fluidframework/` namespace)
Here's a list of other sets of other packages (each package within these groups is versioned independently,
forming its own release group):
- "Common" Packages: miscellaneous packages in the [./common](./common) directory and published under the `@fluidframework/` namespace. Most of these (but not all) have "common" in their package name.
Packages which are used by multiple other groups of packages (such as built tools, linter configs and protocol definitions) live here.
- "Tools" Packages: miscellaneous packages in the [./tools](./tools) directory and published under a variety of namespaces.
Logically about the same as "Common", but most of the names include "tools" instead of "common".
- Auxiliary Microservice Packages (supporting Routerlicious)
- [./server](./server) excluding routerlicious, gitrest and historian (Published in the `@fluidframework/` namespace)
- [./docs](./docs): The code and content for <https://fluidframework.com>.
Dependencies between packages in various layers of the system are enforced via a build step called
[layer-check](./tools/build-tools/src/layerCheck). You can view the full list of packages and layers in
[docs/PACKAGES.md](./docs/PACKAGES.md).
## Building
