🪪 Is

A wrapper around Zod to ease type validation and assertions.

It also contains some additional validators, in addition to a spec checker.

📖 Usage

import { coerce, duration, is, parse, url } from "@libs/is"

// `is` re-exports Zod, augmented with additional validators and transformers
const schema = is.object({
  origin: url,
  timeout: duration(is.number().min(0)),
  retries: coerce(is.number().int().nonnegative()).default(3),
})

// `parse()` works like `schema.parse()` but throws a `TypeError` with prettified issues instead of a `ZodError`
parse(schema, { origin: "https://example.com", timeout: "1m 30s", retries: "5" })
// { origin: "https://example.com", timeout: 90000, retries: 5 }
