pipe

Composes transforms from left to right and returns one reusable transform.

function pipe<A, B>(ab: Transform<A, B>): Transform<A, B>;
// Typed overloads continue through four stages.

const toUser = pipe(
  rename({ user_id: "id" }),
  defaults({ role: "viewer" }),
  normalize({ balance: "number" }),
);

const user = toUser({ user_id: 1, balance: "9.50" });

The output of each stage becomes the input to the next stage. Runtime composition uses a synchronous reducer and does not catch transform errors.

note

Type inference is defined for one through four stages. Passing more stages is supported by the runtime implementation but is not represented by a public overload.
