`@playstack/nest-inventory` binds inventory administration to application authorization and operation context.

```ts
PlaystackInventoryModule.forRoot({
  inventory,
  authorize: (request, permission, resourceId) =>
    policy.allows(request, permission, resourceId),
  resolveContext: (request) => auditContext(request),
})
```

Availability reads are advisory; only the portable reservation command promises stock. A queue-neutral worker expires reservations, while the application continues to own routes, scheduling, queue selection, DTOs, and UI.

{/* package-install:start */}

## Install

After confirming [preview access](/docs/packages#access-policy), install the package at your application's shared Playstack version:

```sh
npm install --save-exact @playstack/nest-inventory@0.1.0-beta.1
```

Check the peer requirements below before choosing a runtime or provider.

{/* package-install:end */}

{/* package-reference:start */}

## API entry points and requirements

Reference snapshot: `@playstack/nest-inventory@0.1.0-beta.1`. Import only the entry point your runtime needs. Paths below are relative to the installed package; use **Go to Definition** in your editor to inspect exact parameters, return types and overloads. Do not import the declaration-file paths directly.

| Public entry point | Declaration file |
| --- | --- |
| `@playstack/nest-inventory` | `./dist/index.d.ts` |
| `@playstack/nest-inventory/package.json` | No TypeScript declaration (asset or metadata export). |

Node.js engine requirement: `>=20`. This is not a claim that every entry point works in browsers or Workers.

### Peer dependencies

Keep existing framework versions that satisfy these ranges. Install optional peers only when using the corresponding adapter. The package manager resolves ordinary dependencies separately.

| Peer | Compatible range | When needed |
| --- | --- | --- |
| `@nestjs/common` | `^10.0.0 \|\| ^11.0.0` | Required by the package. |
| `@playstack/core` | `0.1.0-beta.1` | Required by the package. |
| `@playstack/inventory` | `0.1.0-beta.1` | Required by the package. |
| `reflect-metadata` | `^0.1.13 \|\| ^0.2.0` | Required by the package. |
| `rxjs` | `^7.0.0` | Required by the package. |

For a complete first program, start with [Getting started](/docs/getting-started). For API lookup and partial-example conventions, see [Reading the reference](/docs/packages#reading-the-reference). Provider failures, lifecycle requirements and application responsibilities remain described in the guide above; types alone do not establish production safety.
