# Block Editor This module allows you to create and use standalone block editors. ## Installation Install the module ```bash npm install @gechiui/block-editor --save ``` _This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for such language features and APIs, you should include [the polyfill shipped in `@gechiui/babel-preset-default`](https://github.com/GeChiUI/gutenberg/tree/HEAD/packages/babel-preset-default#polyfill) in your code._ ## Usage ```js import { BlockEditorProvider, BlockList, BlockTools, WritingFlow, ObserveTyping, } from '@gechiui/block-editor'; import { SlotFillProvider, Popover } from '@gechiui/components'; import { useState } from '@gechiui/element'; function MyEditorComponent() { const [ blocks, updateBlocks ] = useState( [] ); return ( updateBlocks( blocks ) } onChange={ ( blocks ) => updateBlocks( blocks ) } > ); } // Make sure to load the block editor stylesheets too // import '@gechiui/components/build-style/style.css'; // import '@gechiui/block-editor/build-style/style.css'; ``` In this example, we're instantiating a block editor. A block editor is composed by a `BlockEditorProvider` wrapper component where you pass the current array of blocks and on each change the `onInput` or `onChange` callbacks are called depending on whether the change is considered persistent or not. Inside `BlockEditorProvider`, you can nest any of the available `@gechiui/block-editor` UI components to build the UI of your editor. In the example above we're rendering the `BlockList` to show and edit the block list. For instance we could add a custom sidebar and use the `BlockInspector` component to be able to edit the advanced settings for the currently selected block. (See the [API](#API) for the list of all the available components). The `BlockTools` component is used to render the toolbar for a selected block. In the example above, there's no registered block type, in order to use the block editor successfully make sure to register some block types. For instance, registering the core block types can be done like so: ```js import { registerCoreBlocks } from '@gechiui/block-library'; registerCoreBlocks(); // Make sure to load the block stylesheets too // import '@gechiui/block-library/build-style/style.css'; // import '@gechiui/block-library/build-style/editor.css'; // import '@gechiui/block-library/build-style/theme.css'; ``` ## API ### AlignmentControl Undocumented declaration. ### AlignmentToolbar Undocumented declaration. ### Autocomplete _Related_ - ### BlockAlignmentControl Undocumented declaration. ### BlockAlignmentToolbar Undocumented declaration. ### BlockBreadcrumb Block breadcrumb component, displaying the hierarchy of the current block selection as a breadcrumb. _Parameters_ - _props_ `Object`: Component props. - _props.rootLabelText_ `string`: Translated label for the root element of the breadcrumb trail. _Returns_ - `GCElement`: Block Breadcrumb. ### BlockColorsStyleSelector Undocumented declaration. ### BlockContextProvider Component which merges passed value with current consumed block context. _Related_ - _Parameters_ - _props_ `BlockContextProviderProps`: ### BlockControls Undocumented declaration. ### BlockEdit Undocumented declaration. ### BlockEditorKeyboardShortcuts Undocumented declaration. ### BlockEditorProvider Undocumented declaration. ### BlockFormatControls Undocumented declaration. ### BlockIcon Undocumented declaration. ### BlockInspector Undocumented declaration. ### BlockList Undocumented declaration. ### BlockMover Undocumented declaration. ### BlockNavigationDropdown Undocumented declaration. ### BlockPreview BlockPreview renders a preview of a block or array of blocks. _Related_ - _Parameters_ - _preview_ `Object`: options for how the preview should be shown - _preview.blocks_ `Array|Object`: A block instance (object) or an array of blocks to be previewed. - _preview.viewportWidth_ `number`: Width of the preview container in pixels.

The element should be the outermost element of a block. Call this hook and pass the returned props to the element to mark as a block. If you define a ref for the element, it is important to pass the ref to this hook, which the hook in turn will pass to the component through the props it returns. Optionally, you can also pass any other props through this hook, and they will be merged and returned. _Parameters_ - _props_ `Object`: Optional. Props to pass to the element. Must contain the ref if one is defined. - _options_ `Object`: Options for internal use only. - _options.\_\_unstableIsHtml_ `boolean`: _Returns_ - `Object`: Props to pass to the element to mark as a block. ### useCachedTruthy Keeps an up-to-date copy of the passed value and returns it.

Call this hook and pass the returned props to the element to mark as an inner blocks wrapper, automatically rendering inner blocks as children. If you define a ref for the element, it is important to pass the ref to this hook, which the hook in turn will pass to the component through the props it returns. Optionally, you can also pass any other props through this hook, and they will be merged and returned. _Related_ - _Parameters_ - _props_ `Object`: Optional. Props to pass to the element. Must contain the ref if one is defined. - _options_ `Object`: Optional. Inner blocks options. ### useSetting Hook that retrieves the editor setting.

For use with the default editor/theme color palette. _Usage_ ```jsx export default compose( withColors( 'backgroundColor', { textColor: 'color' } ), MyColorfulComponent ); ``` _Parameters_ - _colorTypes_ `...(Object|string)`: The arguments can be strings or objects. If the argument is an object, it should contain the color attribute name as key and the color context as value. If the argument is a string the value should be the color attribute name, the color context is computed by applying a kebab case transform to the value. Color context represents the context/place where the color is going to be used. The class name of the color is generated using 'has' followed by the color name and ending with the color context all in kebab case e.g: has-green-background-color. _Returns_ - `Function`: Higher-order component. ### withFontSizes Higher-order component, which handles font size logic for class generation, font size value retrieval, and font size change handling. _Parameters_ - _fontSizeNames_ `...(Object|string)`: The arguments should all be strings. Each string contains the font size attribute name e.g: 'fontSize'. _Returns_ - `Function`: Higher-order component. ### WritingFlow Handles selection and navigation across blocks. This component should be wrapped around BlockList. _Parameters_ - _props_ `Object`: Component properties. - _props.children_ `GCElement`: Children to be rendered.
