Workspace (ruang kerja)

pnpm memiliki dukungan bawaan untuk monorepositori (repositori multi paket, repositori multi proyek, atau repositori monolitik). Anda dapat membuat workspace untuk menyatukan beberapa proyek di dalam satu repositori.

Sebuah workspace haruslah memiliki pnpm-workspace.yaml di dalam folder akarnya. Sebuah workspace juga mungkin perlu memiliki .npmrc di dalam folder akarnya.

Protokol workspace (workspace:)

Secara asali, pnpm akan menautkan paket dari workspace jika paket tersedia cocok dengan rentang yang dideklarasikan. Misalnya, foo@1.0.0 akan ditautkan ke bar jika bar memiliki "foo": "^1.0.0" dalam dependensinya. Namun, jika bar memiliki "foo": "2.0.0" dalam dependensi dan foo@2.0.0 tidak ada di workspace, maka foo@2.0.0 akan diinstal dari registri. Perilaku ini memperkenalkan beberapa ketidakpastian.

Untungnya, pnpm mendukung protokol workspace:. Ketika protokol ini digunakan, pnpm akan menolak untuk menyelesaikan apa pun selain paket workspace lokal. Jadi, jika Anda menyetel "foo": "workspace:2.0.0", kali ini instalasi akan gagal karena "foo@2.0.0" tidak ada di workspace.

Protokol ini sangat berguna ketika opsi link-workspace-packages disetel ke false. Dalam hal ini, pnpm hanya akan menautkan paket dari workspace jika protokol workspace: digunakan.

Merujuk paket workspace melalui alias

Katakanlah Anda memiliki paket di workspace bernama foo. Biasanya, Anda akan mereferensikannya sebagai "foo": "workspace:*".

Jika Anda ingin menggunakan alias yang berbeda, sintaks berikut juga akan berfungsi: "bar": "workspace:foo@*".

Sebelum dipublikasikan, alias dikonversi ke dependensi alias biasa. Contoh di atas akan menjadi: "bar": "npm:foo@1.0.0".

Merujuk paket workspace melalui jalur relatifnya

Di workspace dengan 2 paket:

+ packages
    + foo
    + bar

bar mungkin memiliki foo dalam dependensinya yang dinyatakan sebagai "foo": "workspace:../foo". Sebelum dipublikasikan, spesifikasi ini dikonversi ke spesifikasi versi reguler yang didukung oleh semua pengelola paket.

Memublikasikan paket workspace

Ketika paket workspace dikemas ke dalam sebuah arsip (baik itu melalui pnpm pack atau salah satu perintah terbitkan seperti pnpm publish), kami secara dinamis menggantikan setiap dependensi workspace: dengan:

• The corresponding version in the target workspace (if you use workspace:*, workspace:~, or workspace:^)
• The associated semver range (for any other range type)

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.

Options

link-workspace-packages

• Default: true
• Type: true, false, deep

If this is enabled, locally available packages are linked to node_modules instead of being downloaded from the registry. This is very convenient in a monorepo. If you need local packages to also be linked to subdependencies, you can use the deep setting.

Else, packages are downloaded and installed from the registry. However, workspace packages can still be linked by using the workspace: range protocol.

prefer-workspace-packages

• Default: false
• Type: Boolean

If this is enabled, local packages from the workspace are preferred over packages from the registry, even if there is a newer version of the package in the registry.

This setting is only useful if the workspace doesn't use save-workspace-protocol.

shared-workspace-lockfile

• Default: true
• Type: Boolean

If this is enabled, pnpm creates a single pnpm-lock.yaml file in the root of the workspace. This also means that all dependencies of workspace packages will be in a single node_modules (and get symlinked to their package node_modules folder for Node's module resolution).

Advantages of this option:

• every dependency is a singleton
• faster installations in a monorepo
• fewer changes in code reviews as they are all in one file

note

Even though all the dependencies will be hard linked into the root node_modules, packages will have access only to those dependencies that are declared in their package.json, so pnpm's strictness is preserved. This is a result of the aforementioned symbolic linking.

save-workspace-protocol

• Default: true
• Type: Boolean

If this is enabled, new dependencies will be added with the workspace protocol IF (and only if) they are present in the workspace.

You might want to change this setting to false if the tooling in your repository does not understand the workspace protocol (and ideally submit a PR to your tooling to get it added in the future).

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.
