Simple Key with Function

const keys = createKeyFactory('base', {
  items: (params: {}) => ['list'],
});

keys.items({}) // => ['base', 'items', 'list']

Nested Structure

const keys = createKeyFactory('app', {
  users: {
    all: () => [],
    detail: (params: { id: string }) => [params.id],
  },
});

keys.users.all({}) // => ['app', 'users', 'all']
keys.users.detail({ id: '123' }) // => ['app', 'users', 'detail', '123']
keys.users() // => ['app', 'users'] (access intermediate level)

Array Shorthand

For static keys, you can use arrays instead of functions:

const keys = createKeyFactory('shop', {
  products: {
    list: ['all'], // Equivalent to () => ['all']
    featured: ['featured', 'items'],
  },
});

keys.products.list() // => ['shop', 'products', 'list', 'all']
keys.products.featured() // => ['shop', 'products', 'featured', 'featured', 'items']
