#flowAsync

Creates an async pipeline that awaits each step before passing the result to the next function. Like flow from es-toolkit but async-aware.

Each function can return a value or a Promise — flowAsync always returns a Promise that resolves to the final step's awaited result.

const getUsername = flowAsync(
  (id: string) => fetchUser(id),  // Promise<User>
  (user) => user.name,            // string
  (name) => name.toUpperCase(),
)
await getUsername('123') // 'ALICE'
