Área de Trabalho

O pnpm tem suporte embutido para mono repositórios (também conhecidos como repositórios multi-pacotes, repositórios multi-projetos ou repositórios monolíticos). Você pode criar uma área de trabalho para unir vários projetos dentro de um único repositório.

Um espaço de trabalho deve ter um arquivo pnpm-workspace.yaml em sua raiz. Um espaço de trabalho também pode ter um arquivo .npmrc em sua raiz.

dica

If you are looking into monorepo management, you might also want to look into Bit. Bit uses pnpm under the hood but automates a lot of the things that are currently done manually in a traditional workspace managed by pnpm/npm/Yarn. There's an article about bit install that talks about it: Painless Monorepo Dependency Management with Bit.

Protocolo do espaço de trabalho (espaço de trabalho:)

By default, pnpm will link packages from the workspace if the available packages match the declared ranges. For instance, foo@1.0.0 is linked into bar if bar has "foo": "^1.0.0" in its dependencies and foo@1.0.0 is in the workspace. However, if bar has "foo": "2.0.0" in dependencies and foo@2.0.0 is not in the workspace, foo@2.0.0 will be installed from the registry. This behavior introduces some uncertainty.

Luckily, pnpm supports the workspace: protocol. When this protocol is used, pnpm will refuse to resolve to anything other than a local workspace package. So, if you set "foo": "workspace:2.0.0", this time installation will fail because "foo@2.0.0" isn't present in the workspace.

This protocol is especially useful when the link-workspace-packages option is set to false. In that case, pnpm will only link packages from the workspace if the workspace: protocol is used.

Referenciando pacotes de áreas de trabalhos via aliases

Let's say you have a package in the workspace named foo. Usually, you would reference it as "foo": "workspace:*".

If you want to use a different alias, the following syntax will work too: "bar": "workspace:foo@*".

Before publish, aliases are converted to regular aliased dependencies. The above example will become: "bar": "npm:foo@1.0.0".

Referenciando pacotes de workspaces por meio de seu caminho relativo

In a workspace with 2 packages:

+ packages
    + foo
    + bar

bar may have foo in its dependencies declared as "foo": "workspace:../foo". Before publishing, these specs are converted to regular version specs supported by all package managers.

Publicando pacotes de workspaces

When a workspace package is packed into an archive (whether it's through pnpm pack or one of the publish commands like pnpm publish), we dynamically replace any workspace: dependency by:

• A versão correspondente da workspace de destino (se você usa workspace:*, workspace:~, ou workspace:^)
• O intervalo semver associado (para qualquer outro tipo de intervalo)

So for example, if we have foo, bar, qar, zoo in the workspace and they all are at version 1.5.0, the following:

{
    "dependencies": {
        "foo": "workspace:*",
        "bar": "workspace:~",
        "qar": "workspace:^",
        "zoo": "workspace:^1.5.0"
    }
}

Will be transformed into:

{
    "dependencies": {
        "foo": "1.5.0",
        "bar": "~1.5.0",
        "qar": "^1.5.0",
        "zoo": "^1.5.0"
    }
}

This feature allows you to depend on your local workspace packages while still being able to publish the resulting packages to the remote registry without needing intermediary publish steps - your consumers will be able to use your published workspaces as any other package, still benefitting from the guarantees semver offers.

Release workflow

Versioning packages inside a workspace is a complex task and pnpm currently does not provide a built-in solution for it. However, there are 2 well tested tools that handle versioning and support pnpm:

• changesets
• Rush.

For how to set up a repository using Rush, read this page.

For using Changesets with pnpm, read this guide.

Troubleshooting

pnpm cannot guarantee that scripts will be run in topological order if there are cycles between workspace dependencies. If pnpm detects cyclic dependencies during installation, it will produce a warning. If pnpm is able to find out which dependencies are causing the cycles, it will display them too.

If you see the message There are cyclic workspace dependencies, please inspect workspace dependencies declared in dependencies, optionalDependencies and devDependencies.
