@aglyn/aglyn-markdown-editor

The markdown-lite WYSIWYG editor: visual surface, toolbar, source/visual toggle, HTML-to-markdown paste, link dialog, and the read-only view. It is the editor the Aglyn console uses for content, and the one @aglyn/besigner-ui uses for a Markdown component's content attribute. Install it on its own if you need to edit or preview Aglyn's markdown-lite dialect in a React and MUI app; most consumers get it as a dependency of @aglyn/besigner-ui.

Published to npm from the Aglyn monorepo. Versions follow semantic versioning.

Install

npm install @aglyn/aglyn-markdown-editor

Peer dependencies:

• react
• @mui/material
• @mui/icons-material

What's in it

Components:

• MarkdownField is the complete field: a label, the toolbar, the visual editor and a raw-source mode, driven by value and onChange. It takes an optional onPickImageFromMedia callback so the caller can supply its own media picker, and an editorRef that hands back a MarkdownFieldHandle for inserting a picked image.
• MarkdownVisualEditor is the visual editing surface by itself, and MarkdownEditorToolbar is its toolbar, for callers that lay the pieces out themselves.
• MarkdownLinkDialog and LinkTargetAutocomplete are the link controls. The autocomplete offers the targets the caller passes in, and searches entries when the core's link-target search context is mounted.
• MarkdownLiteView renders markdown-lite source read-only.

Functions:

• markdownToRows, rowsToMarkdown and readInlinesFromElement convert between markdown-lite source and the editor's row model.
• htmlToRows and htmlToInlines convert pasted HTML.
• applyCommandToSource and applyLinkToSource apply a toolbar command to a raw-source selection.

The markdown-lite dialect itself (its parser and serializer) lives in @aglyn/aglyn, not here. This package is the UI over it.

Every file under src/lib is also reachable by subpath, for example @aglyn/aglyn-markdown-editor/markdown-lite-view.component.

Usage

import { MarkdownField, MarkdownLiteView } from '@aglyn/aglyn-markdown-editor'
import { useState } from 'react'

export function BodyEditor() {
  const [body, setBody] = useState('')
  return (
    <>
      <MarkdownField label="Body" value={body} onChange={setBody} />
      <MarkdownLiteView source={body} />
    </>
  )
}

How it fits

This package sits in the core scope of the package map as its UI piece: it imports only @aglyn/aglyn, because the editor speaks the markdown-lite dialect the core defines. That is also why it is not one of the generic @aglyn/shared-* packages, which may not know Aglyn's model. It is a library rather than part of an app because both the console and the designer UI need the same editor. It imports no plugin and no other UI package.
