locked-prop-descriptors

Property descriptor builder for non-writable, non-configurable property definitions.

Overview

lockedPropertyDescriptors() returns a descriptor map suitable for Object.defineProperties that locks every property as both non-writable and non-configurable, while leaving enumeration controllable per-property. Use it when you need Object.defineProperties-style bulk application but want the safety profile of locked-props — for example, when freezing a class prototype, an exported namespace object, or the public surface of a factory result.

Usage

import { lockedPropertyDescriptors } from '@hyperfrontend/immutable-api-utils/locked-prop-descriptors'

const descriptors = lockedPropertyDescriptors({
  name: 'service',
  version: '1.0.0',
  build: () => ({}),
})

const surface = Object.defineProperties({}, descriptors)
surface.name = 'spoofed' // TypeError in strict mode

When to use

Pick locked-prop-descriptors/ when you want full control over how the descriptors are applied (custom target object, mixing with non-locked descriptors, mass-defining on a prototype). For the more common case of locking properties on an object you already have, locked-props/ is the higher-level shortcut.
