    rich-markdown-editor

    A React and Prosemirror based editor that powers Outline and can also be used for displaying content in a read-only fashion. The editor is WYSIWYG and includes formatting tools whilst retaining the ability to write markdown shortcuts inline and output plain Markdown.

    Important Note: This project is not attempting to be an all-purpose Markdown editor. It is built for the Outline knowledge base, and whilst others are welcome to fork or use this package in your own products, development decisions are centered around the needs of Outline.

    Usage

    Install

    yarn add rich-markdown-editor

    or

    npm install rich-markdown-editor

    Note that react, react-dom, and styled-components are required peer dependencies.

    Import

    import Editor from "rich-markdown-editor";
    
    <Editor
      defaultValue="Hello world!"
    />

    Clone this repo and run the Storybook with yarn start to see a wide variety of example usage.

    Props

    id

    A unique id for this editor, used to persist settings in local storage. If no id is passed then the editor will default to using the location pathname.

    defaultValue

    A markdown string that represents the initial value of the editor. Use this to prop to restore previously saved content for the user to continue editing.

    value

    A markdown string that represents the value of the editor. Use this prop to change the value of the editor once mounted, this will re-render the entire editor and as such is only suitable when also in readOnly mode. Do not pipe the value of onChange back into value, the editor keeps it's own internal state and this will result in unexpected side effects.

    placeholder

    Allows overriding of the placeholder. The default is "Write something nice…".

    readOnly

    With readOnly set to false the editor is optimized for composition. When true the editor can be used to display previously written content – headings gain anchors and links become clickable.

    readOnlyWriteCheckboxes

    With readOnlyWriteCheckboxes set to true checkboxes can still be checked or unchecked as a special case while readOnly is set to true and the editor is otherwise unable to be edited.

    autoFocus

    When set true together with readOnly set to false, focus at the end of the document automatically.

    maxLength

    When set enforces a maximum character length on the document, not including markdown syntax.

    extensions

    Allows additional Prosemirror plugins to be passed to the underlying Prosemirror instance.

    theme

    Allows overriding the inbuilt theme to brand the editor, for example use your own font face and brand colors to have the editor fit within your application. See the inbuilt theme for an example of the keys that should be provided.

    dictionary

    Allows overriding the inbuilt copy dictionary, for example to internationalize the editor. See the inbuilt dictionary for an example of the keys that should be provided.

    dark

    With dark set to true the editor will use a default dark theme that's included. See the source here.

    tooltip

    A React component that will be wrapped around items that have an optional tooltip. You can use this to inject your own tooltip library into the editor – the component will be passed the following props:

    • tooltip: A React node with the tooltip content
    • placement: Enum top, bottom, left, right
    • children: The component that the tooltip wraps, must be rendered

    headingsOffset

    A number that will offset the document headings by a number of levels. For example, if you already nest the editor under a main h1 title you might want the user to only be able to create h2 headings and below, in this case you would set the prop to 1.

    scrollTo

    A string representing a heading anchor – the document will smooth scroll so that the heading is visible in the viewport.

    embeds

    Optionally define embeds which will be inserted in place of links when the matcher function returns a truthy value. The matcher method's return value will be available on the component under props.attrs.matches. If title and icon are provided then the embed will also appear in the block menu.

    <Editor
      embeds={[
        {
          title: "Google Doc",
          keywords: "google docs gdocs",
          icon: <GoogleDocIcon />,
          defaultHidden: false,
          matcher: href => href.matches(/docs.google.com/i),
          component: GoogleDocEmbed
        }
      ]}
    />

    Callbacks

    uploadImage(file: Blob): Promise<string>

    If you want the editor to support images then this callback must be provided. The callback should accept a single File object and return a promise the resolves to a url when the image has been uploaded to a storage location, for example S3. eg:

    <Editor
      uploadImage={async file => {
        const result = await s3.upload(file);
        return result.url;
      }}
    />

    onBlur(): void

    This callback is triggered when the user loses focus on the editor contenteditable and all associated UI elements such as the block menu and floating toolbars. If you want to listen for blur events on only the contenteditable area then use handleDOMEvents props.

    onFocus(): void

    This callback is triggered when the user gains focus on the editor contenteditable or any associated UI elements such as the block menu or floating toolbars. If you want to listen for focus events on only the contenteditable area then use handleDOMEvents props.

    onSave({ done: boolean }): void

    This callback is triggered when the user explicitly requests to save using a keyboard shortcut, Cmd+S or Cmd+Enter. You can use this as a signal to save the document to a remote server.

    onCancel(): void

    This callback is triggered when the Cmd+Escape is hit within the editor. You may use it to cancel editing.

    onChange(() => value): void

    This callback is triggered when the contents of the editor changes, usually due to user input such as a keystroke or using formatting options. You may use this to locally persist the editors state.

    It returns a function which when called returns the current text value of the document. This optimization is made to avoid serializing the state of the document to text on every change event, allowing the host app to choose when it needs the serialized value.

    onImageUploadStart(): void

    This callback is triggered before uploadImage and can be used to show some UI that indicates an upload is in progress.

    onImageUploadStop(): void

    Triggered once an image upload has succeeded or failed.

    onSearchLink(term: string): Promise<{ title: string, subtitle?: string, url: string }[]>

    The editor provides an ability to search for links to insert from the formatting toolbar. If this callback is provided it should accept a search term as the only parameter and return a promise that resolves to an array of objects. eg:

    <Editor
      onSearchLink={async searchTerm => {
        const results = await MyAPI.search(searchTerm);
    
        return results.map(result => {
          title: result.name,
          subtitle: `Created ${result.createdAt}`,
          url: result.url
        })
      }}
    />

    onCreateLink(title: string): Promise<string>

    The editor provides an ability to create links from the formatting toolbar for on-the-fly document createion. If this callback is provided it should accept a link "title" as the only parameter and return a promise that resolves to a url for the created link, eg:

    <Editor
      onCreateLink={async title => {
        const url = await MyAPI.create({
          title
        });
    
        return url;
      }}
    />

    onShowToast(message: string, type: ToastType): void

    Triggered when the editor wishes to show a message to the user. Hook into your app's notification system, or simplisticly use window.alert(message). The second parameter is the type of toast: 'error' or 'info'.

    onClickLink(href: string, event: MouseEvent): void

    This callback allows overriding of link handling. It's often the case that you want to have external links open a new window and have internal links use something like react-router to navigate. If no callback is provided then default behavior of opening a new tab will apply to all links. eg:

    import { history } from "react-router";
    
    <Editor
      onClickLink={(href, event) => {
        if (isInternalLink(href)) {
          history.push(href);
        } else {
          window.location.href = href;
        }
      }}
    />

    onHoverLink(event: MouseEvent): boolean

    This callback allows detecting when the user hovers over a link in the document.

    <Editor
      onHoverLink={event => {
        console.log(`Hovered link ${event.target.href}`);
      }}
    />

    onClickHashtag(tag: string, event: MouseEvent): void

    This callback allows handling of clicking on hashtags in the document text. If no callback is provided then hashtags will render as regular text, so you can choose if to support them or not by passing this prop.

    import { history } from "react-router";
    
    <Editor
      onClickHashtag={tag => {
        history.push(`/hashtags/${tag}`);
      }}
    />

    handleDOMEvents: {[name: string]: (view: EditorView, event: Event) => boolean;}

    This object maps event names (focus, paste, touchstart, etc.) to callback functions.

    <Editor
      handleDOMEvents={{
        focus: () => console.log("FOCUS"),
        blur: () => console.log("BLUR"),
        paste: () => console.log("PASTE"),
        touchstart: () => console.log("TOUCH START"),
      }}
    />

    Interface

    The Editor component exposes a few methods for interacting with the mounted editor.

    focusAtStart(): void

    Place the cursor at the start of the document and focus it.

    focusAtEnd(): void

    Place the cursor at the end of the document and focus it.

    getHeadings(): { title: string, level: number, id: string }[]

    Returns an array of objects with the text content of all the headings in the document, their level in the hierarchy, and the anchor id. This is useful to construct your own table of contents since the toc option was removed in v10.
