# About the Manifest

<blockquote class="caution">

__Alpha:__
Editor React Components are currently in alpha. This feature is subject to change and may have bugs, issues, and limitations. We're actively improving it based on your feedback.

</blockquote>

The manifest is a TypeScript configuration object for your [Editor React Component](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/about-editor-react-components.md).

It declares what's customizable about your component, such as editable text, styling, layout, and presets, so the editor can build matching [auto panels](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/panels/about-auto-panels.md). At runtime, the same manifest defines your component's [prop contract](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/runtime-props.md).

For the full property reference, see [Root Properties](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/root-properties/root-properties.md).

## Auto-generated manifest

You don't need to write the manifest from scratch.

When you [scaffold a component with the CLI](https://dev.wix.com/docs/build-apps/develop-your-app/frameworks/wix-cli/supported-extensions/site/editor-react-components/add-an-editor-react-component-extension-with-the-wix-cli.md), the CLI generates the initial manifest files for that scaffolded component.

As you iterate on your component, keeping the manifest in sync depends on how you work:

- **Manual edits**: The manifest doesn't stay in sync automatically while you edit files yourself. Regenerate it by running [`wix generate manifest`](https://dev.wix.com/docs/wix-cli/command-reference/project-commands/app-only/generate-manifest.md).
- **AI edits with the Wix skill**: Manifest regeneration happens as part of the Editor React Component [Wix skill](https://dev.wix.com/docs/wix-cli/command-reference/global-commands/skills-add.md) workflow.

## How the editor uses your manifest

Most of your work happens inside `editorElement`, where each property you declare drives a specific [auto panel](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/panels/about-auto-panels.md) or editor behavior. For the per-property reference, see [Editor Element](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/editor-element.md).

## Immutable type properties

After you create the manifest for the first time, the following type properties are immutable. Changing any of them from its originally saved value results in a validation error and blocks deployment. To use a different type, add a new variable with the desired name and type instead of modifying the existing one.

- `dataType`: The type of a [data item](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/data/about-data.md).
- `elementType`: The type of an [element](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/elements.md).
- `cssPropertyType`: The type of a [CSS custom property](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/css/css-custom-properties.md).
- `refElement.type`: The type of a [ref element](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/elements.md).

## Structural validation constraints

The following structural issues result in validation errors:

- A required type property is undefined.
- A data item with `dataType: "data"` is missing its `data` property or has an empty `items` map.
- A data item with `dataType: "arrayItems"` is missing its `arrayItems` property or doesn't define `data`, `dataItem`, or `dynamicItems`.

## Unsupported features

The following manifest features aren't currently supported:

- **Translations**: Some manifest properties, such as `displayName` in [data items](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/data/about-data.md), [presets](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/presets.md), and [actions](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/actions/native-and-custom-actions.md), as well as the top-level [`resources`](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/root-properties/resources.md) property, support translations. However, the translation mechanism isn't yet available.
- **Ref elements**: The [`refElement`](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/elements.md) element type, which lets you reference and reuse existing Wix components with optional overrides, isn't yet supported. Only [`inlineElement`](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/elements.md) is available.
