## 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](https://github.com/DefinitelyTyped/DefinitelyTyped); 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` |
| License | `MIT` |
| Types | `index.d.ts` |
| Runtime dependencies | `expect, pretty-format` |

## Installation

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

Preserve existing imports and plugin resolution with an npm alias:

```bash
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.
