Why this package?

@stackline/types-jest is the Stackline-maintained distribution of @types/jest@30.0.0. It is an independent continuation of @types/jest; original authors and licenses remain credited below.

Compatibility

Item Value
Package @stackline/types-jest@1.0.2
API target @types/jest@30.0.0
Supported Node.js See supported framework requirements

Types index.d.ts
Runtime dependencies expect, pretty-format

Installation

npm install --save-dev @stackline/types-jest

Preserve existing imports and plugin resolution with an npm alias:

npm install --save-dev @types/jest@npm:@stackline/types-jest

Use the original @types/* alias for automatic TypeScript type discovery and existing compilerOptions.types settings. A scoped-only installation does not automatically expose the original type-package name.

Usage and API reference

Installation

npm install --save @stackline/types-jest

Upstream issues and maintenance review

Upstream and review

Issue review

GitHub search on 2026-09-29 used repo:DefinitelyTyped/DefinitelyTyped is:issue is:open "jest" and the corresponding closed query. Counts: open: 17 results (collected 17), closed: 133 results (collected 100). Search results can contain unrelated packages; they are not evidence that every result is a defect here. Archived search responses and baseline comparisons are retained in the release research evidence. No issue was posted or modified.

Issue #34617 (each done callbacks) is already supported by the selected declarations; the original reproduction is a positive compile test. #41179 requests new assertion-function semantics and is not a safe compatibility fix. #60223 requests broader callbacks; existing strict void/promise callback contract is preserved. Historical reports against Jest 23-27 do not justify changing the selected Jest30 API.

Validation

Real declaration usage and negative type assertions are compiled with TypeScript 5.4.6 and 5.9.3, with strict: true and skipLibCheck: false, from source and isolated direct/alias tarball installs. CI also checks the complete dependency audit, CodeQL, package contents and exact CI archive identity before GitHub-only publication. Registry verification compiles direct and aliased installs rather than importing these type-only packages as JavaScript.

Correct the inherited typeScriptVersion: 5.1 metadata to 5.4, the already-established minimum of Jest30 (https://jestjs.io/docs/upgrading-to-jest30). The original 5.1 compilation fails in upstream jest-mock declarations on esnext.disposable; no declaration API or dependency major was changed. The published Jest30 line remains unchanged and is tested with TypeScript5.4.5 and5.9.3.
