WarpDrive (formerly EmberData) is the lightweight data library for web apps —
universal, typed, reactive, and ready to scale.

***Warp*Drive** makes it easy to build scalable, fast, feature rich applications — letting you ship better experiences more quickly without re-architecting your app or API. ***Warp*Drive** is: - 🌌 Seamless Reactivity in any Framework - ⚡️ Committed to Best-In-Class Performance - 💚 Typed - ⚛️ Works with any API - 🌲 Focused on being as tiny as possible - 🚀 SSR Ready - 🐹 Built with ♥️ by [Ember](https://emberjs.com)

> [!WARNING] > **Legacy Package** > > The `ember-data` package is a **legacy umbrella package** that bundles older EmberData patterns including `@ember-data/model`, `@ember-data/adapter`, and `@ember-data/serializer`. > > **Why it's legacy:** This package represents an older architecture based on class inheritance, runtime schema parsing, and the Adapter/Serializer pattern. Modern WarpDrive uses: > - **`@warp-drive/core`** packages for framework-agnostic data management > - **`@warp-drive/ember`** packages for Ember-specific integrations > - **Schema objects** instead of Model classes > - **Request builders** and **Handlers** instead of Adapters/Serializers > > **When to use this package:** Only use `ember-data` if you're maintaining an existing Ember application that hasn't migrated to modern WarpDrive patterns. For new projects or modern WarpDrive apps, install packages from `@warp-drive/*` directly. > > **Migration path:** See the [Guides](https://warp-drive.io/guides/) for migration strategies.
