Permix is a lightweight, framework-agnostic, type-safe permissions management library for JavaScript applications on the client and server sides.

/**
 * Create a per-request Permix helper for TanStack Start.
 *
 * Uses TanStack Start's per-request server context to share a single Permix
 * instance across global middleware, server routes, server functions, and the
 * router for the lifetime of each request.
 *
 * Use `.contextKey('name')` to set a custom context key (defaults to
 * `'__permix'`).
 *
 * @example
 * ```ts
 * // lib/permix.ts
 * import { createPermix } from 'permix/tanstack-start'
 *
 * export const permix = createPermix<{
 *   post: ['create', 'read', 'update', 'delete']
 * }>()
 * ```
 *
 * ```ts
 * // src/start.ts
 * import { createStart } from '@tanstack/react-start'
 * import { getSession } from './lib/auth'
 * import { permix } from './lib/permix'
 *
 * export const startInstance = createStart(() => ({
 *   requestMiddleware: [
 *     permix.setupMiddleware(async ({ request }) => {
 *       const session = await getSession(request)
 *       return {
 *         post: {
 *           create: !!session,
 *           read: true,
 *           update: session?.role === 'admin',
 *           delete: session?.role === 'admin',
 *         },
 *       }
 *     }),
 *   ],
 * }))
