# @vue/observer
## Usage Note
This package is inlined into Global & Browser ESM builds of user-facing renderers (e.g. `@vue/renderer-dom`), but also published as a package that can be used standalone. The standalone build should not be used alongside a pre-bundled build of a user-facing renderer, as they will have different internal storage for reactivity connections. A user-facing renderer should re-export all APIs from this package.
## Credits
The implementation of this module is inspired by the following prior art in the JavaScript ecosystem:
- [Meteor Tracker](https://docs.meteor.com/api/tracker.html)
- [nx-js/observer-util](https://github.com/nx-js/observer-util)
- [salesforce/observable-membrane](https://github.com/salesforce/observable-membrane)
## Caveats
- Built-in objects are not observed except for `Map`, `WeakMap`, `Set` and `WeakSet`.
