safeChain()

safeChain<In, Out>(...handlers): (input) => Result<Out, Error>

Creates a safe chain that catches errors and returns a zygos Result. Behaves like createChain, but wraps the execution in a try/catch.

DEPRECATED

Use Result.fromThrowable from @zygos/result/result instead.

import { Result } from "@zygos/result/result";

const chain = createChain(auth, validate, handle);
const safeRun = Result.fromThrowable(
  (input: Request) => chain(input),
  (e) => e instanceof Error ? e : new Error(String(e)),
);
const result = safeRun(request);
