pnpm 12 registrySupportsTimeField release-age verification abbreviated metadata

💡 Result:

The registrySupportsTimeField setting in pnpm is a boolean configuration used to optimize dependency resolution when using time-based resolution modes or features requiring package release timestamps [1][2]. Background and Purpose Standard abbreviated metadata (the compact format typically requested by package managers to speed up installations) does not include the time field, which contains publication timestamps [3][4]. Features such as resolutionMode: time-based require these timestamps to function [2][4]. Without registrySupportsTimeField enabled, pnpm is forced to fetch full metadata—which is significantly slower—to access the necessary time information [1][2][4]. If a registry is configured to include the time field in its abbreviated metadata, setting registrySupportsTimeField to true allows pnpm to use the faster abbreviated format while still accessing the required temporal data [1][2]. Verification and Support As of August 2026, the primary registry documented to support including the time field in abbreviated metadata is Verdaccio (version 5.15.1 and later) [1][2]. Related Considerations 1. Errors: If pnpm expects time metadata that is missing, it may throw an ERR_PNPM_MISSING_TIME error [5][6]. This often occurs when using features like resolutionMode: time-based or trustPolicy: no-downgrade [5][7][6]. 2. Release Age: There is a related setting, minimumReleaseAgeIgnoreMissingTime (default: true), which controls whether pnpm skips the minimumReleaseAge check if the registry metadata lacks the time field [8][5]. This prevents installations from failing unnecessarily when working with registries that do not provide this data [8]. 3. Global Config vs. Local Config: Technical issues have been identified where global trust policies (e.g., trustPolicy: no-downgrade) could trigger ERR_PNPM_MISSING_TIME even if the registry provides the time field, because the internal logic incorrectly fetched abbreviated metadata for global operations [7][6]. This has been addressed in recent updates [7].

site:github.com/pnpm/pnpm "registrySupportsTimeField" "minimumReleaseAge"

💡 Result:

registrySupportsTimeField is a configuration setting in pnpm used to indicate whether a package registry provides the necessary "time" metadata field required for time-based dependency resolution features [1][2][3]. This setting acts as a gate for features that depend on per-version publish dates [2]. Specifically, when pnpm's resolution mode is set to time-based or when a trust policy such as no-downgrade is active, pnpm requires access to the package's publish time [2][4]. If the registry does not provide this information—or if pnpm is unable to retrieve it—these features may fail with an error such as ERR_PNPM_MISSING_TIME [4][5]. By setting registrySupportsTimeField to false, you inform pnpm that the registry cannot be relied upon for this metadata, which influences how pnpm fetches and processes package metadata [2]. This setting is frequently relevant when using registries (like certain private artifact repositories) that do not preserve or provide the original publication timestamps for packages [6]. Related configuration options include: minimumReleaseAge: Defines the required age (in minutes) for a package release to be considered eligible for installation [1][7]. minimumReleaseAgeIgnoreMissingTime: A setting that, when enabled (default is true), allows pnpm to proceed even if the "time" field is missing, effectively bypassing the time-based check for those specific packages [4][5].

Separate registrySupportsTimeField from minimumReleaseAge.

pnpm uses registrySupportsTimeField for resolutionMode: time-based. pnpm 12 obtains minimumReleaseAge timestamps through a separate on-demand metadata path. Since this benchmark uses the default resolution mode, document the setting as time-based compatibility, not as a current release-age optimization.

In `@benchmarkFixture.js` around lines 183 - 190, Update the comment describing
registrySupportsTimeField to state that it documents compatibility with pnpm’s
time-based resolution mode, and remove the claim that it optimizes
minimumReleaseAge or prevents full-packument refetches. Keep the explanation
limited to the benchmark registry’s support for the per-version time map.
