Zoltan Kochan e0d8cc6d7c fix(pnpr): omit storage metadata from npm package responses (#17855)
Filter formatVersion and null access values at the existing npm response
boundary. Keep storage metadata and explicit access values intact.

Cover hosted publish/read responses and preserve the name@version tarball
URL format. Missing-email display is outside this change because authenticated
identities have no email address.

endpoints HTTP endpoints

pnpr exposes a set of always-on endpoints (health, user accounts, and tokens) plus four surfaces:

  • Registry surface - npm-compatible package, publish, staged-publish, and team endpoints, plus the Cargo, Python, and image protocols. Served exactly when at least one registry is declared under registries:; --disable-registry turns it off for one process. On a resolver-only server these routes aren't mounted at all. They answer 404, not 403.
  • Resolver surface (resolver.enabled) - pnpr install-accelerator endpoints under /-/pnpr.
  • Shared-artifact surface (artifacts.enabled) - signed artifact publish, lookup, and blob endpoints under /-/pnpr, plus the compiler cache. It may run without the resolver.
  • Pipeline run surface (pipeline.enabled) - the pnpm pipeline run records under /-/pnpr.

See Configuration for the config keys and CLI reference for the command-line overrides.

The npm tables below show paths relative to the npm base, /npm/. Each is equally available under an /npm/~<name>/ prefix. The always-available endpoints, the /-/pnpr/v0/ protocol endpoints, and the image /v2/ API sit on the server root. Cargo, Python, and image endpoints are documented on their own pages.

npm error responses

Errors on npm registry and account endpoints use application/json with matching error and reason fields containing the server's explanation. Server faults hide internal details. A 401 includes a WWW-Authenticate: Bearer challenge. When a supplied token is invalid, the explanation is "Invalid authentication token" and the challenge includes error="invalid_token". Missing credentials produce an "Authentication required" explanation.

Always available

Method Path Description
GET /-/ping Health check. Returns {} on success, or 503 if storage or auth is unavailable.
GET /-/ready Container / Kubernetes readiness probe. Checks storage and auth backends, returning {"status": "ok", "storage": "ok", "auth": "ok"} on success or 503 on failure.
GET /-/live Container / Kubernetes liveness probe. Returns {"status": "ok"} when the server process is alive and handling requests.
GET /-/pnpr/v0/sign-in The OIDC providers that offer browser sign-in, as {"oidc": [{"name": ...}]}.
GET /-/oidc/{provider}/login Starts browser sign-in. With ?return=ui, sign-in ends in the web UI instead of on a page that shows the token. pnpr refuses return=ui when it does not serve the web UI.
POST /-/oidc/handoff?flow=<flow> Returns {"token": ..., "expires": ...} for the sign-in flow that a sign-in with return=ui passes to the web UI. The token is released only to the browser that signed in, once, within a minute.

GET /-/metrics and GET /metrics serve Prometheus metrics only when metrics is configured.

The user and token endpoints below are also always available, whichever surfaces are enabled.

Registry bases: /npm/ and /npm/~<name>/

Every registry is served as a full npm registry at /npm/~<name>/. Packument and tarball reads, version manifests, dist-tags, search, publish, unpublish, and the login/whoami endpoints all work under a registry prefix. The ~ prefix keeps registry names out of the package-name namespace (a package name can never begin with ~).

npm publishes require a lowercase, URL-safe package name of at most 214 characters. The package part cannot contain ~'!()*. Unscoped names cannot start with ., _, or -, and Node.js built-in module names, node_modules, and favicon.ico are reserved. Existing upstream names retain their legacy read behavior.

The npm base (/npm/) aliases the registry named by defaultRegistry. With no defaultRegistry configured, it serves no registry and only the /npm/~<name>/ bases answer.

Every request routes through the registry graph:

  • A request to a router is answered by the first listed source whose declared packages: claim the name. A name that no source claims is a definitive 404. There is no fall-through to another origin. A matched source that is unavailable is an error, never a 404.
  • A registry's declared namespace is enforced on every path to it: a read of a name outside the namespace is a definitive 404 answered before storage or the upstream is consulted (through a router, on the default base, and at the registry's own /~<name>/ URL alike), and an off-namespace publish is rejected.
  • Writes (publish, dist-tags, unpublish) must resolve to a hosted registry; a write that routes to an upstream is rejected.
  • The serving registry's matching packages: rule is enforced on every read and write.
  • Served dist.tarball URLs are rewritten onto --public-url (PNPR_PUBLIC_URL) as <registry>/<name>@<version> and stay canonical for the base the client addressed (/npm/ or /npm/~<name>/), so lockfiles don't bake in a registry name.
  • Full package metadata omits access when its value is null.

pnpr protocol endpoints

The capability handshake is served when any of the four surfaces is enabled. Each protocol advertises its versions independently, so resolver-only and artifact-only tiers are both valid. The POST endpoints require a valid pnpr Authorization header.

Method Path Description
GET /-/pnpr Capability handshake. Returns versions for resolver protocols, fixLockfile for resolver versions that support lockfile repair, ecosystems for the ecosystems the resolver serves, artifacts for shared-artifact protocols, publish for the cross-ecosystem publish transaction, and pipeline for pipeline run records. Each version list is [0] when its surface is enabled and [] otherwise. records is [1] when hosted registries log their release records, with the profiles they derive them under in manifestProfiles, and [] otherwise. A 404 means every surface is off.
POST /-/pnpr/v0/resolve Resolves one project or workspace against the registries and policy sent by the client. Returns application/x-ndjson frames.
POST /-/pnpr/v0/verify-lockfile Verifies an existing lockfile under the client's registry and policy settings without resolving again. Returns application/x-ndjson frames.

POST /-/pnpr/v0/resolve accepts fields such as projects, dependencies, devDependencies, optionalDependencies, registry, registries, overrides, lockfile, frozenLockfile, preferFrozenLockfile, ignoreManifestCheck, trustLockfile, minimumReleaseAge, minimumReleaseAgeExclude, minimumReleaseAgeIgnoreMissingTime, trustPolicy, trustPolicyExclude, trustPolicyIgnoreAfter, and fixLockfile. A repair request regenerates broken lockfile metadata while retaining compatible locked versions, including for a filtered install.

The registries map is keyed by URL. Each entry can carry a prefix and an optional aliases list. All declared prefixes resolve to that URL. The smallest prefix in alphabetical order determines package keys in the returned lockfile, including when the input lockfile uses another declared prefix.

Every registry the request would make pnpr fetch from (the registry and registries origins, plus any direct http(s)/git URL in a dependency spec, an override, or an input-lockfile tarball) must be on the server's fetch allowlist. An off-allowlist origin is rejected up front, before any server-side fetch. Upstream credentials are never taken from the client: pnpr selects its own server-owned credential per route (see Install acceleration), and a URL carrying inline user:pass@ credentials is rejected.

The resolve response is an NDJSON stream:

Frame Description
package One resolved tarball: id, name, version, integrity, tarball, and optional unpackedSize / fileCount / requiresBuild.
done Terminal success frame. For resolve, carries lockfile and stats.totalPackages; for verify-lockfile, only indicates success.
violations Terminal policy failure frame. Carries rendered lockfile or OSV violations.
error Terminal server-side resolution or verification error.

Shared-artifact endpoints

Added in: v0.1.0-alpha.8

These three are mounted when top-level artifacts.enabled is true, independently of resolver.enabled. They serve the shared side-effects cache proof of concept and, like the other POST resolver endpoints, require a pnpr Authorization header. Artifacts are owned by an organization, and artifacts.orgs decides who may read and who may publish what each one owns.

Method Path Description
PUT /-/pnpr/v0/artifacts Stores one immutable opaque signed envelope in its organization's namespace. Every blob its manifest names is already stored or carried inline, base64-encoded, up to 64 MiB in all. Requires publish on that organization. At most eight variants per input key; a different artifact whose compatible consumers overlap an existing variant gets 409 Conflict.
PUT /-/pnpr/v0/artifacts/blob?organization=<name>&integrity=<sha512-…> Stores one blob, streamed from the request body, ahead of the envelope that names it. Requires publish on that organization and a Content-Length of at most 4 GiB. The blob is stored only if its bytes match the integrity. A blob nothing references yet is kept for at least an hour.
HEAD /-/pnpr/v0/artifacts/blob?organization=<name>&integrity=<sha512-…> Whether the blob is stored, with its size as Content-Length.
POST /-/pnpr/v0/artifacts/resolve One batched lookup for candidate input keys. Returns at most eight signed variants per key; scanned envelope bytes plus the serialized response share one 16 MiB budget.
POST /-/pnpr/v0/artifacts/blob Reads one owner-scoped blob by its SHA-512 integrity.
GET HEAD PUT /-/pnpr/v0/compiler-cache/{cache}/{key} One Cargo compilation cache entry, over the subset of WebDAV sccache uses. PROPFIND answers for virtual parent directories. Added in v0.1.0-alpha.11.

Cross-ecosystem endpoints

Added in: v0.1.0-alpha.11

These belong to no single ecosystem, so they sit on the server root.

Method Path Description
PUT /-/pnpr/v0/publish Publish packages of any ecosystem in one transaction. Advertised as publish: [0] in the handshake.
PUT /-/pnpr/v0/artifacts/blob?integrity=<sha512-…> Stages one release archive for the caller, streamed from the request body, ahead of the publish that references it. Also under /npm/. Answers 201 when stored, 200 when the caller had it staged already, which renews it. Needs a signed-in caller and a Content-Length of at most 100 MiB. The archive is stored only if its bytes match the integrity. Only the caller can claim it, for 24 hours after its last upload.
HEAD /-/pnpr/v0/artifacts/blob?integrity=<sha512-…> Whether the caller has the archive staged with at least an hour left, with its size as Content-Length.
GET /-/pnpr/v0/registries The registry directory: the named registries, ecosystem endpoints, and routing order the caller may see.

Publication endpoints

Served from the hosted metadata database, SQLite or libSQL. A publication is a commit that introduced packages. Its id is the org generation it committed. <org> is - for registries without an org.

Method Path Description
GET /-/publications/<org>/<id-or-name> The publication, with the members the caller may read: ecosystem, name, version, and artifact (an npm archive's integrity, or another ecosystem's file name). 404 when the caller may read none of them.
GET /-/publications/<org>?member=npm:<name>@<version> The publication that introduced that npm version. 404 when the caller may not read the package. Members of other ecosystems record no version, so they cannot be looked up this way.

Release note endpoints

Served from the hosted metadata database, SQLite or libSQL. A note is Markdown of at most 64 KiB, with no control characters other than line feed and tab, no carriage returns, and no bidirectional overrides. A publish can send notes with it (see One publish for a workspace that spans ecosystems), and a single npm publish document can carry its version note in a top-level notes field.

Method Path Description
GET /npm/<name>/<version>/notes The version's note as text/markdown. <version> may be a dist-tag. 204 when only the version's publication has a note, with a Link: <…>; rel="publication-notes" header. A version published with a note carries PNPR-Note-Initial-Digest, the digest of the text it was published with, even after an edit or deletion.
PUT, DELETE /npm/<name>/<version>/notes Replace or delete the version's note. Requires the package's publish rule.
GET /npm/<name>/-/notes Every note of the package as JSON, newest version first, at most 100 entries and 1 MiB, with "truncated": true when more exist. A version whose publication has a note the caller may read names it in publication, whose url is the note's path on the server, including the path of public_url, as in the Link header of the version route.
GET, PUT, DELETE /-/publications/<org>/<id-or-name>/notes The publication's note. Reading needs read access to every member, writing needs every member's publish rule.

A response that anyone may read is cached public, max-age=300. Any other is private, no-store. pnpr keeps every earlier text of a note for recovery. An unpublished version's note is no longer served or listed. A package that routes to an upstream registry has no notes: its list is empty, and a single note answers 404.

Pipeline run endpoints

Added in: v0.1.0-alpha.11

Mounted when pipeline.enabled is true. See Pipeline run records.

Method Path Description
PUT /-/pnpr/v0/pipeline/runs Record one run. Requires publish on its organization.
GET /-/pnpr/v0/pipeline/runs Recent run summaries, newest first. Accepts org, workspace, and limit.
GET /-/pnpr/v0/pipeline/runs/{org}/{workspace}/{run_id} One run's full record, event stream included.
GET /-/pnpr/v0/pipeline A static web viewer over the two read endpoints.

Registry read endpoints

These endpoints are mounted when the registry surface is served. Package reads are checked against the serving registry's matching packages: rule.

Method Path Description
GET /{name} Unscoped package packument.
GET /@scope/{name} Scoped package packument.
GET /{name}/{version-or-tag} Unscoped version manifest by exact version or dist-tag.
GET /@scope/{name}/{version-or-tag} Scoped version manifest by exact version or dist-tag.
GET /{name}@{version}/variants/{tag} Unscoped platform variant tar.
GET /@scope/{name}@{version}/variants/{tag} Scoped platform variant tar.
GET /{name}/{version}+r{revision} Unscoped release record. See pnpr's package document.
GET /@scope/{name}/{version}+r{revision} Scoped release record.
GET /{name}/{version}+r{revision}/evidence Unscoped release record's evidence. See Release record logs.
GET /@scope/{name}/{version}+r{revision}/evidence Scoped release record's evidence.
GET /-/log/checkpoint The latest checkpoint of the registry's release record log.
GET /-/log/tile/{level}/{index} A hash tile of the log, .p/{width} appended to a partial one.
GET /-/log/tile/entries/{index} An entry bundle of the log, only for callers who may read every package it holds.
GET /{name}/-/{filename} Unscoped tarball. Not served by a tar registry.
GET /@scope/{name}/-/{filename} Scoped tarball. Not served by a tar registry.
GET /{name}@{version} Unscoped tarball by exact version: the .tgz, or on a tar registry the tar.
GET /@scope/{name}@{version} Scoped tarball by exact version.
GET /{name}@{version}+r{revision} Unscoped package tar by exact version and revision. See Registry revisions.
GET /@scope/{name}@{version}+r{revision} Scoped package tar by exact version and revision. See Registry revisions.
GET /-/package/{package}/dist-tags Package dist-tags object. Use a percent-encoded scoped package name, for example @scope%2Fname.
GET /-/v1/search?text=<query>&size=<n> npm search v1 shape. Searches locally hosted packages by package-name substring, and the upstreams that opt in with search: true. Results are filtered by access policy. Pass browse=true to page through hosted packages with no search term.
GET /-/org/{scope}/package Packages of one organization, on registries that enable discovery. Added in v0.1.0-alpha.11.

If the client sends Accept: application/vnd.npm.install-v1+json, pnpr returns npm's abbreviated install-v1 packument shape. If it sends application/vnd.pnpr.install-v2+json, pnpr returns its own package document. Package documents carry a pnpr-registry response header.

Packument responses emit strong ETag and Vary: Accept headers at the origin. A reverse proxy that changes the content coding may weaken the ETag. Cloudflare documents this behavior. Public packuments set Cache-Control: public, max-age=<ttl> based on upstream or global packument TTL configuration, while private or caller-scoped responses set Cache-Control: private, no-store and Vary: Accept, Authorization. Conditional requests sending If-None-Match or If-Modified-Since receive 304 Not Modified when unchanged.

When OSV checks are enabled, vulnerable versions are removed from packuments and dist-tags. Version manifests and tarballs for vulnerable versions are denied.

The /{name}@{version}+r{revision} route answers registry revisions. Each revision's dist.integrity is the SHA-512 of the uncompressed tar, on every registry, .tgz and tar registries alike. The response is the tar with Content-Type: application/x-tar, sent with the gzip or zstd content coding the client's Accept-Encoding allows, or with none, and Vary: Accept-Encoding. It carries no ETag, and a Range request gets the whole body.

For a proxied upstream registry, pnpr forwards the request with its own credentials and accepts a gzip-encoded or plain tar. It decodes the whole response and checks the tar against the revision's dist.integrity in the upstream packument before it caches or serves any of it. For a hosted registry, revision 0 serves the tar of the published .tgz once its tar integrity has been verified. Every 3xx fails a revision fetch on the client side, same-origin included.

pnpr keeps an upstream's revision fields only when they form a complete revision record: dist.revision, including 0 for the original, a dist.tarball on the <name>@<version>+r<revision> route, and a dist.revisions history that lists revision 0 once and the selected revision once. Such a version's dist omits shasum and signatures, which describe a .tgz, on either registry format. npm's documents give the selected revision by its +r<revision> tarball URL and its integrity, without dist.revision and dist.revisions. pnpr's own package document marks it with revision, and each revision in the history has its own release record.

When pnpr has verified a version's tarball (at publish time, on first read, or while streaming and caching an upstream tarball), its full packument, abbreviated application/vnd.npm.install-v1+json packument, and single-version manifest include dist.fileCount and dist.unpackedSize. pnpr's own package document and the version's release record also include requiresBuild (true when the tarball's root package.json declares preinstall, install, or postinstall under scripts, when the tarball contains a root binding.gyp and package.json does not set gypfile: false, or when it contains a .hooks/ entry; false otherwise). When requiresBuild is false and the package declares executables via bin or directories.bin, they also include bins, mapping each command name to its normalized package-relative path and optional prog / args runtime. Any dist.pnpr field supplied by a publisher or an upstream packument is stripped and never trusted.

pnpr's package document

A client that sends Accept: application/vnd.pnpr.install-v2+json gets pnpr's own package document, with Content-Type: application/vnd.pnpr.install-v2+json:

{
  "name": "fast-thing",
  "distTags": { "latest": "2.1.0" },
  "modified": "2026-10-01T10:00:00.000Z",
  "timesSince": "2026-09-01T10:00:00.000Z",
  "versions": {
    "1.4.0": {},
    "1.4.1": { "deprecated": "1.x is no longer maintained" },
    "1.5.0": { "trust": "provenance", "revision": 2 },
    "2.1.0": {
      "time": "2026-10-01T10:00Z",
      "integrity": "sha512-...",
      "requiresBuild": false,
      "manifest": { "dependencies": { "detect-libc": "^2.0.0" } }
    }
  }
}

Each version's entry may have:

  • time: the publish time, only when the version was published at or after timesSince, which is publishTimeWindow before the package's last publish. null when pnpr has no publish time.
  • deprecated, trust (provenance, trustedPublisher, or stagedPublish), and revision, the selected revision of a revision-aware version.
  • integrity, fileCount, unpackedSize, requiresBuild, bins, and manifest, the publisher's abbreviated manifest without dist, name, version, and deprecated.

Below splitThreshold, every entry has its manifest. Above it, only every dist-tag target and the highest release of each major version (of each minor version below 1.0) keep theirs. Every other version's manifest and facts are in its release record, at /{name}/{version}+r{revision}:

{
  "name": "fast-thing",
  "version": "1.5.0",
  "integrity": "sha512-...",
  "manifest": { "dependencies": { "detect-libc": "^2.0.0" } }
}

A hosted version is accepted with its release record, and pnpr serves the record's bytes as they were accepted. Such a record starts with the fields every release record has:

{
  "schema": "pnpr-release-record/1",
  "purl": "pkg:npm/fast-thing@1.5.0",
  "name": "fast-thing",
  "version": "1.5.0",
  "revision": 0,
  "interpretation": "npm-install-manifest/1",
  "inputs": {
    "archive": { "kind": "tgz", "integrity": "sha512-..." },
    "packageJson": { "path": "package/package.json", "integrity": "sha512-..." },
    "shrinkwrap": null
  },
  "integrity": "sha512-...",
  "manifest": { "dependencies": { "detect-libc": "^2.0.0" } }
}

interpretation is the profile the manifest was derived under, and inputs are the digests it was derived from: the .tgz as published, and its package.json and npm-shrinkwrap.json by their paths in the archive. Each platform variant in variants has inputs of its own, and a purl: the record's with a variant qualifier naming its tag, with + written %2B, such as pkg:npm/fast-thing@1.5.0?variant=linux-x64%2Blinux-x64-musl. A registry with tarballs: tar serves the record with the tar's integrity.

Revision 0 is the original artifact, also of a version without registry revisions. A release record never changes once pnpr has verified the archive it describes, so from then on it is served with Cache-Control: public, max-age=31536000, immutable. Before that, it has no Cache-Control header, since verifying the archive can add fileCount, unpackedSize, requiresBuild, and bins. A package closed to anonymous callers gets Cache-Control: private, no-store for its records. /{name}/{version} keeps serving the selected revision in npm's format.

Release record logs

With releaseRecords.logSigningKey, each hosted organization's release records are appended to a transparency log, in the C2SP tiled log format Go's checksum database uses. A registry address serves the log of the one hosted organization it reaches, under /-/log/. A registry that reaches no hosted organization, or several, serves no log.

  • /-/log/checkpoint is the log's latest checkpoint, a signed note. It changes as the log grows, so it is served with Cache-Control: no-cache.
  • /-/log/tile/{level}/{index} and /-/log/tile/entries/{index} are the log's hash tiles and entry bundles. A tile never changes once written, so it is cached forever.

Anyone who may read a package of the organization reads its checkpoint and hash tiles. An entry bundle names every package logged with it, so only a caller who may read every package of the organization gets the entry bundles; anyone else gets a 404 for every bundle. When some package is closed to anonymous callers, these responses are Cache-Control: private, no-store.

A record's evidence, /{name}/{version}+r{revision}/evidence, is read as the record is:

{
  "record": "sha512-<record digest>",
  "inclusion": { "checkpoint": "<signed note>", "index": 12, "proof": ["<base64 hash>"] },
  "statements": [],
  "sigstore": []
}

record is the digest of the record's bytes, index is its entry's place in the log, and proof is its inclusion proof against the checkpoint. statements holds, with releaseRecords.statementSigningKey, the registry's acceptance statement: an in-toto Statement in a DSSE envelope, with predicate type https://pnpm.io/pnpr/acceptance/v1, saying the registry accepted the record under its profile. pnpr signs it from the accepted record on every read, so a new key signs every statement again. sigstore holds the provenance bundle published with the version, if any. A record whose entry is not in the log yet makes the read wait for a few seconds; after that it answers 503 with Retry-After. The evidence changes with every newer checkpoint, so it is served with Cache-Control: no-cache.

Registry write endpoints

These endpoints are mounted when the registry surface is served. PUT and DELETE requests require credentials. A read-only bearer token cannot use write methods, and CIDR-restricted bearer tokens are checked against the peer socket address. Every write routes through the registry graph and must land on a hosted registry.

Method Path Description
PUT /{name} Publish an unscoped package. Body is the npm publish document with _attachments. Requires publish.
PUT /@scope/{name} Publish a scoped package. Body is the npm publish document with _attachments. Requires publish.
PUT /-/pnpr/v0/publish pnpm batch publish (also mounted on the server root). Body is {"packages":[<publish document>, ...]}. The batch is all-or-nothing and each package requires publish. See One publish for a workspace that spans ecosystems.
PUT /{package}/-rev/{rev} Replace a packument, used by partial unpublish. Requires the current revision and both publish and unpublish. Use a percent-encoded scoped package name, for example @scope%2Fname.
DELETE /{name} Remove an entire unscoped package, used by force unpublish. Requires unpublish. Legacy /{package}/-rev/{rev} is also accepted.
DELETE /@scope/{name} Remove an entire scoped package, used by force unpublish. Requires unpublish. Legacy /@scope/{name}/-rev/{rev} is also accepted.
DELETE /{name}@{version} Unpublish an unscoped version, and reclaim its archives that no other file shares. A version the package no longer lists is left as it is. Requires unpublish. Legacy /{name}@{version}/-rev/{rev} is also accepted.
DELETE /@scope/{name}@{version} Unpublish a scoped version, as above. Requires unpublish. Legacy /@scope/{name}@{version}/-rev/{rev} is also accepted.
DELETE /{name}/-/{filename} Unpublish the unscoped version the tarball belongs to, as above. Requires unpublish. Legacy /{name}/-/{filename}/-rev/{rev} is also accepted.
DELETE /@scope/{name}/-/{filename} Unpublish the scoped version the tarball belongs to, as above. Requires unpublish. Legacy /@scope/{name}/-/{filename}/-rev/{rev} is also accepted.
PUT /-/package/{package}/dist-tags/{tag} Add or update a dist-tag. Body is a JSON string naming a published version, for example "1.0.0". Names that parse as semver ranges and targets that are missing or unpublished return 400. Requires publish.
DELETE /-/package/{package}/dist-tags/{tag} Remove a dist-tag. Removing latest while published versions exist returns 400. Requires publish.

dist-tags in publish requests and package-document updates follows the same name and target rules. A package-document update cannot remove latest while published versions remain.

Every key under versions and its manifest's version must be valid SemVer. pnpr rejects an invalid version with 400, including versions in DELETE requests. Publish version keys with build metadata, such as 1.0.0+build.5, return 400 with a message explaining that build metadata cannot be published.

Packument revisions

A hosted package's full metadata document includes _rev. A partial unpublish PUT must use that value in /{package}/-rev/{rev}. If the body also includes _rev, it must match the path. A stale revision returns 409 without removing versions. Read the package metadata again before retrying.

A deprecation PUT to /{package} must include the current _rev. It changes only the versions' deprecated fields. Dist-tags and other package metadata stay unchanged. A missing or stale _rev returns 409.

Platform variants

A hosted version can carry platform variants: archives that pnpm links in place of the version's own archive on the platforms they declare. Each variant is a complete package whose package.json has the version's name and version and declares its platforms as platform tags:

{ "name": "fast-thing", "version": "1.4.0", "variant": { "platforms": ["linux-x64", "linux-x64-musl"] } }

A tag is <os>-<cpu>, then optionally musl or a glibc floor (manylinux_2_28), a macOS or Windows floor (macos_11_0, windows_10_0), an N-API floor (napi8) or a Node.js or Electron ABI (node127, electron130); or wasm32. Only the canonical form is accepted.

A variant's tag is its platforms' tags, sorted and joined with +, such as linux-x64+linux-x64-musl, and at most 128 bytes long. The publish document attaches each variant as <basename>-<version>~<tag>.tgz, with the .tgz's integrity beside its data, or with integrity alone for an archive staged before the publish, so a version's archives are not bounded by one request body. pnpr rejects the version when a variant:

  • has another name or version, or other peerDependencies or peerDependenciesMeta, than the version;
  • requires a build;
  • has no variant field, one that does not parse, or an os, cpu, or libc field;
  • declares platforms that give another tag than the one that names it;
  • lists a platform another variant lists;
  • is attached for a version the publish document does not describe, or without an integrity.

A version published with a provenance statement (its .sigstore attachment) is rejected unless the statement names every archive of the version: the .tgz that dist.tarball names by the version's PURL, such as pkg:npm/%40acme/fast@1.0.0, and each variant's .tgz by its PURL with the variant qualifier, each with its SHA-512.

A variant may differ from the version in its files, dependencies, bundled dependencies, bin, main, exports, and engines. pnpr serves a variant's tar at /{name}@{version}/variants/{tag}, and at /{name}@{version}+r{revision}/variants/{tag} while that revision is selected.

Only pnpr's package document and release records list the variants, under variants: each with its tag, structured platforms, tar integrity, sizes, bins, and a manifest of the fields that differ from the version's (null for a removed field). npm's documents do not list them, so npm clients install the version's own archive, its any archive.

A version can also be published with variants only: its publish document has no dist and no <basename>-<version>.tgz attachment. pnpr then generates the archive npm's documents point to, a package.json that lists the union of the variants' os, cpu, and Linux libc, so npm reports an unsupported platform instead of installing an empty package. pnpr's package document and the release record describe such a version without a top-level integrity, by the manifest its variants share: their peer dependencies, and each dependency every variant declares with the same specifier.

Publishing a version that already exists is a 409. On the S3 backend, where several stateless replicas can write to one bucket, concurrent writers are resolved by conditional writes rather than last-write-wins. A publish or partial unpublish computed from a packument that another replica has since changed is rejected with a 409; a dist-tag write instead replays its mutation against the fresh packument, and reports 409 only if it keeps losing. Either way no writer's update is silently discarded. See Packument revisions and Storage backends.

Publish-time manifest verification

An npm publish document carries each version's metadata beside its archive, and nothing in the npm protocol requires the two to agree. pnpr verifies every published .tgz against the metadata submitted for it, under the npm-install-manifest/1 interpretation profile:

  1. The .tgz must decode in full to a tar within the decode limit, and the tar must name its manifest unambiguously. Each of these is a 400:
    • an entry of any type whose path escapes the package root;
    • a second entry that an installer would extract to package.json or npm-shrinkwrap.json, including one that differs only in case;
    • a package.json or npm-shrinkwrap.json that is a link;
    • a missing package.json, one larger than 4 MiB, or one that is not a JSON object;
    • non-zero data, or more than 10,752 bytes of zeros, after the end-of-archive marker;
    • a global PAX header that sets size, path, or linkpath;
    • more than 200,000 entries, or file paths that add up to more than 32 MiB.
  2. pnpr derives the install-critical fields from the archive's package.json and from the submitted version metadata, normalizes both the way npm's publish-time prepare() and npm 9's normalize-package-data rewrite a manifest, and compares them. The fields are name, version, dependencies, optionalDependencies, peerDependencies, peerDependenciesMeta, bundleDependencies, os, cpu, libc, engines, bin (with directories.bin expanded into it), and the preinstall, install, and postinstall scripts, including the node-gyp rebuild an installer runs for a root binding.gyp. The archive's name and version must also name the package and version being published. A version compares without semver build metadata, and is published without it, as npm publishes it: an archive version 1.0.0-canary.1+abc is published as 1.0.0-canary.1, and a version with build metadata, such as the +r<N> of a registry revision, cannot be published. Any difference rejects the publish with a 400 whose message names the package, the version, and each differing field.
  3. One difference is accepted: a submitted scripts.install: "node-gyp rebuild" that the archive cannot run, because it has no root binding.gyp or sets gypfile: false, while every other lifecycle script agrees. npm adds that script whenever any *.gyp file is in the source directory, even one the archive leaves out. The publish succeeds, the response carries an npm-notice header that npm prints to the publisher, and the script is not served.

The stored version's install-critical fields are then the ones derived from the archive, and it always carries hasInstallScript and _hasShrinkwrap. Fields outside the profile, such as description or repository, are kept as submitted. _archiveManifest records the profile and the SHA-512 digests of the archive's exact package.json and npm-shrinkwrap.json bytes:

"_archiveManifest": {
  "profile": "npm-install-manifest/1",
  "packageJson": "sha512-...",
  "npmShrinkwrap": "sha512-..."
}

A staged publish is verified when it is approved.

Staged publishing endpoints

These implement the server half of pnpm stage, npm's staged publishing workflow, where a version is uploaded first and promoted later. A staged version is held back rather than made visible: it isn't installable, and nothing is written under the package's name until it is approved. That lets an unattended CI job upload a release for a human to promote, and it doubles as a review gate: the held tarball can be downloaded and audited before it goes live.

The two phases check different things. Staging validates the publish document and requires the publish right on the package, exactly as a direct publish does, but does not check whether the version already exists. Approval re-checks the publish right against the rules as they stand then, and is where a version conflict is caught. pnpr raises no one-time-password challenge of its own at either point. The --otp flag on pnpm stage approve is for registries that do.

A stage id is a v4 UUID drawn from the OS CSPRNG, so the id itself acts as an unguessable handle. Held records live under a reserved .staged/ namespace in the hosted store (both the filesystem and S3 backends), and a record is only visible through the same base it was created with. One staged through /npm/~<name>/ is not addressable on the npm base, and vice versa.

Method Path Description
POST /-/stage/package/{name} Stage a publish. Body is the same npm publish document a PUT /{name} publish carries, _attachments included. Use a percent-encoded scoped name, for example @scope%2Fname. Returns 201 with {"ok":true,"stageId":"<uuid>"}. Requires publish.
GET /-/stage List held records, oldest first. Accepts page (zero-based, defaults to 0), perPage (defaults to 100, clamped to 1 to 100), and package (exact name filter). Returns {"items":[...],"page":...,"perPage":...,"total":...}.
GET /-/stage/{id} One held record. Requires publish on the record's package.
GET /-/stage/{id}/tarball The held tarball as application/octet-stream, for inspection before approval. Requires publish.
POST /-/stage/{id}/approve Publish the held document and drop the record. Empty body; returns 201 with {"ok":true}. Requires publish.
DELETE /-/stage/{id} Reject: delete the record and its tarball without publishing. Returns 204. Requires publish.

Each record carries id, packageName, version, tag, createdAt, actor, actorType, and shasum.

Approving a version that landed meanwhile returns 409 and leaves the record in place, so it can still be inspected or rejected.

GET /-/stage filters rather than refuses: it always answers 200, listing only the records the caller could publish, so an anonymous caller sees an empty list instead of a 401. Every other stage endpoint denies loudly (401 for anonymous callers, 403 for authenticated ones), matching the publish endpoint rather than masking as a 404.

Team endpoints

pnpr serves npm's team endpoints in the shape pnpm team consumes. Teams are registry-scoped.

Method Path Description
GET /-/org/{scope}/team Teams of the registry that serves @{scope}. Requires membership in one of its teams or administrator access. Returns a JSON array of {"id": ..., "name": ...}. The scope may be written with or without a leading @.
GET /-/team/{scope}/{team}/user Members of one team. Requires membership in one of the registry's teams or administrator access. Returns a JSON array of {"id": ..., "name": ...}.
PUT /-/org/{scope}/team Create a team. The body is {"name": "<team>"}. Returns 201.
DELETE /-/team/{scope}/{team} Destroy a team. Returns 200.
PUT /-/team/{scope}/{team}/user Add a member. The body is {"user": "<username>"}. Returns 201.
DELETE /-/team/{scope}/{team}/user Remove a member by {"user": "<username>"} or {"userId": "<account-id>"}. Account IDs also remove deleted members. Returns 204, also when the user was not a member. A username with no account returns 404.

Changes are accepted only on a registry with teamsManagedBy: api:

  • On any other registry a change returns 403 with the error code teams_config_managed.
  • The caller must be one of the auth.admins. Others get 401 when anonymous and 403 when signed in.
  • Creating a team that exists, or destroying one a packages: rule names, returns 409. Changing a team that does not exist returns 404.

Reads resolve @{scope} to a hosted registry the same way a package read in that scope would, then check that registry's default access: list. Unlike the stage endpoints, a denial here is masked as 404. Team and member names must not become an existence probe for a private registry. A registry that declares no teams returns an empty array.

Team package access

npm access grant, npm access revoke, and npm access list packages <scope:team> edit and read the packages: rules of a registry with rulesManagedBy: api.

The {team} path segment is a team name. The stored team:<id> token uses the immutable team ID returned by the team endpoints.

Method Path Description
GET /-/team/{scope}/{team}/package Requires registry team membership or administrator access. The packages: keys whose access list names team:<id> and admits the caller, as {"<key>": "read-only" | "read-write"}. read-write means the key's publish list names the team too.
PUT /-/team/{scope}/{team}/package Grant access. The body is {"package": "<name>", "permissions": "read-only" | "read-write"}. Both add team:<id> to the package's access list. read-write adds it to publish too, and read-only removes it from publish. Returns 201.
DELETE /-/team/{scope}/{team}/package Revoke access. The body is {"package": "<name>"}. Removes team:<id> from the package's access, publish, and unpublish lists. Returns 204.
  • The package must be a packages: key of its own, such as '@acme/app'. A package that only a pattern such as '@acme/*' covers returns 400, because editing the pattern would grant every package it covers.
  • A grant edits the lists that apply to the package now, and stores only the lists it changes, the same way a PUT to the rules admin API does.
  • The caller must be one of the auth.admins, and the team must exist.
  • On a registry without rulesManagedBy: api a change returns 403 with rules_config_managed.

User and token endpoints

These endpoints are always mounted on the server root and under any /~<name>/ prefix, whichever surfaces are enabled. A server with an npm registry also serves them under /npm/ and /npm/~<name>/. pnpm login therefore works against a pnpr npm registry URL, and against the root of a resolver-only server that exposes no registry surface.

Method Path Description
POST /-/v1/login Initiates npm/pnpm browser SSO login. Returns 202 Accepted with loginUrl and doneUrl when OIDC login is configured, or 404 to fall back to basic auth.
GET /-/v1/login/start Browser entry point for SSO login. Validates the session and redirects to the configured OIDC provider or renders a provider picker.
GET /-/v1/login/poll/{session} CLI polling endpoint (doneUrl). Returns 202 Accepted with Retry-After: 1 while pending, or 200 OK with the bearer token once authenticated.
PUT /-/user/{name} npm adduser/login endpoint. Also accepts legacy /-/user/org.couchdb.user:{name}. Creates a user only when auth.users.maxUsers allows registration. Passwords must contain at least 8 characters and at most 71 bytes. Returns a bearer token.
GET /-/user/{name} Requires authentication. Also accepts legacy /-/user/org.couchdb.user:{name}. Returns the public user document when the account exists.
GET /-/whoami Returns {"username": ...} for the authenticated caller.
GET /-/npm/v1/user npm profile endpoint. Returns the authenticated username and placeholder profile fields.
GET /-/npm/v1/tokens Lists bearer tokens for the authenticated caller in npm-compatible shape. The server records a token's last use at most once a minute.
DELETE /-/npm/v1/tokens/token/{key} Revokes one of the caller's tokens by listing-side token key.
DELETE /-/user/token/{token} npm logout endpoint. Revokes the raw bearer token in the path when it belongs to the authenticated caller.

Admin endpoints

These endpoints are always mounted, on the server root only. Each requires one of the auth.admins. Others get 401 when anonymous and 403 when signed in.

Method Path Description
GET /-/pnpr/v0/admin/users Every active account, as {"users": [{"id": ..., "name": ...}]}, sorted by name.
PUT /-/pnpr/v0/admin/users/{name} Create the account (201) or replace its password (200). The body is {"password": "..."}. Creating ignores maxUsers.
PATCH /-/pnpr/v0/admin/users/{id} Rename an account with {"name": "..."}. Its ID, tokens, and grants stay with it.
DELETE /-/pnpr/v0/admin/users/{id} Delete the account and revoke its credentials. The login name becomes available; a replacement account receives a fresh ID. Returns 204.
GET /-/pnpr/v0/admin/users/{id}/tokens The account's tokens, in the shape of GET /-/npm/v1/tokens.
DELETE /-/pnpr/v0/admin/users/{id}/tokens/{key} Revoke one of the account's tokens. Returns 204, or 404 when the account does not hold that key.
GET /-/pnpr/v0/admin/rules/{ecosystem}/{name} The hosted registry's current rules: access, and the access, publish, and unpublish lists of each packages: key (null where the key falls back to the registry's default). rulesManagedBy says whether they can be changed, and version (also the ETag) names the stored changes.
PUT /-/pnpr/v0/admin/rules/{ecosystem}/{name} Replace the stored rule changes with the body, and return the rules that result. Only on a registry with rulesManagedBy: api; elsewhere 403 with rules_config_managed.
DELETE /-/pnpr/v0/admin/rules/{ecosystem}/{name} Drop the stored rule changes, so the config's rules apply again. Returns 204.

To keep two admins from overwriting each other's changes, send the version you read as If-Match with a PUT or DELETE. If the stored changes have moved on since, the request answers 412 and changes nothing. Without If-Match, or with If-Match: *, the last change wins. A weak tag such as W/"..." never matches, and an If-Match that is not a list of quoted versions answers 400.

A rules body lists only what changes. Each list replaces the config's list of the same place:

{
  "access": ["$authenticated"],
  "packages": {
    "@corp/*": { "access": ["team:<team-id>"], "publish": ["<account-id>"] }
  }
}

A key the registry's packages: map does not declare, a malformed token, or a team: reference to a team the registry does not have returns 400. The {ecosystem} and {name} are the pair the registry directory lists, for example npm/private.

With the default account file store, each replica keeps its own accounts, so an account change reaches only the replica that served it. Use a shared auth backend to run several replicas.
