pnpm 內建了對單一存放庫 (又稱為多重套件存放庫、多重專案存放庫或整合型存放庫) 的支援。 您可以建立一個工作區來將多個專案結合在一個單一存放庫的內部。
預設情況下，如果可用的套件與已宣告的範圍相符，pnpm 將會連接工作區中的套件。 For instance,
email@example.com is linked into
"foo": "^1.0.0" in its dependencies. However, if
"foo": "2.0.0" in dependencies and
firstname.lastname@example.org is not in the workspace,
email@example.com 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
"firstname.lastname@example.org" 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.
Referencing workspace packages through aliases
Let's say you have a package in the workspace named
foo. Usually, you would reference it as
If you want to use a different alias, the following syntax will work too:
Before publish, aliases are converted to regular aliased dependencies. The above example will become:
Referencing workspace packages through their relative path
In a workspace with 2 packages:
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.
Publishing workspace packages
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:
- The corresponding version in the target workspace (if you use
- The associated semver range (for any other range type)
So for example, if we have
zoo in the workspace and they all are at version
1.5.0, the following:
Will be transformed into:
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.
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:

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
Here are a few of the most popular open source projects that use the workspace feature of pnpm:
