1.0.0

Initial release of @coroboros/clone.

Features

• clone<T>(thing, options?) — deep clone preserving the prototype chain, property descriptors, boxed primitives, native types (Map, Set, Date, RegExp, Error subclasses, TypedArray, DataView, ArrayBuffer, Buffer), and null-prototype objects. Cycle-safe via a WeakMap visited cache.
• freeze<T>(thing) — recursive deep freeze with a WeakSet cycle guard. Skips ArrayBufferView instances (TypedArray, DataView, Buffer) since Object.freeze throws on them.
• Three granular opt-out flags on CloneOptions: cycles, preservePrototype, copyDescriptors. All default true. Composing all three false gives a fast plain-JSON path competitive with rfdc.
• CloneError with code: 'UNSUPPORTED_TYPE' and Error.cause support. clone throws it on functions, Promise, Intl.*, WeakMap, WeakSet, and constructor functions.
• Browser-safe — the Buffer branch reads globalThis.Buffer at module init, so the package works in non-Node bundles.

Documentation

• README ships with a full API reference, the comparison table vs structuredClone / lodash.cloneDeep / rfdc / fast-copy, and the rationale for the prototype + descriptor preservation contract.
• bench/baseline.md documents the 1.0.0 numbers across five fixture buckets (flat-10, nested-100, large-1000, with-cycles, class-instances) on Apple M1 / Node 22.22.2.

Configuration

• TypeScript strict, ES modules + CJS dual build via tsdown targeting Node 22 LTS. Zero runtime dependencies.
• mitata benchmark suite via pnpm bench. fast-check property-test suite alongside the unit tests.
• .github/workflows/ci.yml calls the coroboros/ci@v0 reusable workflow with OIDC Trusted Publisher and npm provenance.
