@zuke/jsr

`@zuke/jsr` — tools for the [JSR](https://jsr.io) registry in Zuke builds:

Symbols

isPublished

function

async function isPublished(pkg: string, version: string, options?: JsrRegistryOptions): Promise<boolean>

Whether pkg@version (e.g. @zuke/core, 0.13.0) is already on JSR.

JsrAddSettings

class

class JsrAddSettings extends JsrSettings

Settings for jsr add (install a JSR dependency).

Member	Signature	Doc
`packages`	`packages(...specs: string[]): this`	Package specs to add, e.g. `@std/assert` (required).
`dev`	`dev(): this`	Add as a development dependency (`--save-dev`).

JsrPublishSettings

class

class JsrPublishSettings extends JsrSettings

Settings for jsr publish.

Member	Signature	Doc
`dryRun`	`dryRun(): this`	Validate without publishing (`--dry-run`).
`allowSlowTypes`	`allowSlowTypes(): this`	Permit slow types in the published package (`--allow-slow-types`).
`allowDirty`	`allowDirty(): this`	Publish even with an uncommitted working tree (`--allow-dirty`).
`noCheck`	`noCheck(): this`	Skip type-checking before publishing (`--no-check`).
`provenance`	`provenance(): this`	Attach provenance attestation in CI (`--provenance`).
`token`	`token(value: string): this`	Authenticate with a token instead of the interactive flow (`--token`). Registered with the run's redactor, so every rendering of the command masks it — a dry-run echo, a failure message. That is as far as it goes: `jsr publish` accepts the token only as a flag, so the value still reaches the child's argv, where `ps` and `/proc/<pid>/cmdline` expose it to every other user on the host and to every process the build starts. There is no environment variable to move it to. On GitHub Actions, prefer OIDC and pass no token at all: the publish is authenticated by the workflow's identity, so there is no credential to expose. This is for the cases where that is not available.

JsrRegistryOptions

interface

interface JsrRegistryOptions

Options shared by the JSR registry helpers.

Member	Signature	Doc
`fetch?`	`fetch?: fetch`	The `fetch` implementation to use. Defaults to the global `fetch`; override it to unit-test without network access.

JsrRemoveSettings

class

class JsrRemoveSettings extends JsrSettings

Settings for jsr remove.

Member	Signature	Doc
`packages`	`packages(...names: string[]): this`	Package names to remove (required).

JsrSettings

class

class JsrSettings extends ToolSettings

Base for all jsr subcommand settings: the binary is jsr.

JsrTasks

const

const JsrTasks: JsrTasksApi

Typed task functions for the jsr CLI.

JsrTasksApi

interface

interface JsrTasksApi

The shape of JsrTasks.

Member	Signature	Doc
`publish`	`publish(configure?: Configure<JsrPublishSettings>): Promise<CommandOutput>`	Publish the package: `jsr publish`.
`add`	`add(configure?: Configure<JsrAddSettings>): Promise<CommandOutput>`	Add a JSR dependency: `jsr add`.
`remove`	`remove(configure?: Configure<JsrRemoveSettings>): Promise<CommandOutput>`	Remove a dependency: `jsr remove`.

jsrVersions

function

async function jsrVersions(pkg: string, options?: JsrRegistryOptions): Promise<Set<string>>

The set of published versions of pkg (a scoped name like @zuke/core). Resolves to an empty set if the package is not found on JSR.

publishedVersions

function

function publishedVersions(meta: unknown): Set<string>

The set of version strings present in a JSR meta.json payload. Tolerant of malformed input: anything without a versions object yields an empty set.
