WeakSets and WeakMaps shows degrading performance as the amount of observed objects increases. Using hidden keys result in better performance especially when repeatedly creating large amounts of reactive proxies. This also makes it possible to more efficiently declare non-reactive objects in userland.

This package is published only for typing and building custom renderers. It is NOT meant to be used in applications.
For full exposed APIs, see src/index.ts. You can also run yarn build runtime-core --types from repo root, which will generate an API report at temp/runtime-core.api.md.
Building a Custom Renderer
import { createRenderer } from '@vue/runtime-core'
const { render, createApp } = createRenderer({
patchProp,
insert,
remove,
createElement,
// ...
})
// `render` is the low-level API
// `createApp` returns an app instance with configurable context shared
// by the entire app tree.
export { render, createApp }
export * from '@vue/runtime-core'
See @vue/runtime-dom for how a DOM-targeting renderer is implemented.
