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.
A workspace must have a pnpm-workspace.yaml file in its
root. A workspace also may have an .npmrc in its root.
If you are looking into monorepo management, you might also want to look into Bit.
Bit usa pnpm internamente e automatiza muitos de seus processos realizados manualmente em um espaço de trabalho tradicional gerenciado por 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:)
If link-workspace-packages is set to true, 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. Este comportamento introduz certas incertezas.
Luckily, pnpm supports the workspace: protocol. Quando este protocolo é utilizado, o pnpm irá se recusar a realizar a resolução de pacote de outro modo que não seja por um pacote do espaço de trabalho local. 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@*".
Antes da publicação, os aliases serão convertidos para seu nome de dependência de origem. 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:
- The corresponding version in the target workspace (if you use
workspace:*,workspace:~, orworkspace:^) - 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:
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.
