@playstack/auth-contracts

Client-safe session contracts for adopting Playstack React and Next.js bindings against any authentication backend.

Free. MIT licensed. Check preview availability before installing. See package access.

@playstack/auth-contracts contains only the safe session projection, parser, and transport-facing types shared by Playstack clients. It has no persistence, crypto, framework, or server-auth dependency.

Install

After confirming preview access, install the package at your application's shared Playstack version:

npm install --save-exact @playstack/auth-contracts@0.1.0-beta.1

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

Adopt the client independently

import { createAuthSessionViewParser } from '@playstack/auth-contracts'

export const parseSession = createAuthSessionViewParser((value) => sessionExtensionsSchema.parse(value))

The default parser rejects unknown fields and credentials. An application can expose additional JSON-safe session data only through an explicit extension parser.

Use this package when an existing backend continues to own authentication while @playstack/auth-react or @playstack/auth-next adopts Playstack's client state and transport conventions.

API entry points and requirements

Reference snapshot: @playstack/auth-contracts@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/auth-contracts`	`./dist/index.d.ts`
`@playstack/auth-contracts/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

This package declares no peer dependencies. Its ordinary dependencies are resolved by the package manager.

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