mdmap

Edit Obsidian notes as mind maps.

Changes in the map are written to the note, and changes in the note show up in the map. The Markdown note is the only place the content is stored; there is no separate mind map file.

Features

• Headings, list items and paragraphs as nodes.
• Two-way sync. Edit the map and the note changes; edit the note, in Obsidian or another app, and the map updates.
• Drag and drop. Drag a node onto another node to change its parent, or to an empty part of the map to keep it there.
• Automatic layouts. Tidy tree, Center root and Radial place every node without overlaps.
• From the map to the note and back. Click a node to highlight its line in the note; put the cursor on a heading in the note to select its node.
• Search. Type in the field at the top of the map, or press Cmd+F, to highlight the nodes that contain the text and jump from one to the next.
• Copy a branch as Markdown, exactly as it is written in the note.
• Mermaid export. Copy the whole note as a Mermaid mindmap block.
• Images and videos embedded in the note are shown inside their node.
• Undo and redo for changes made in the map.

How it works

This note:

# Trip

## Packing
- Passport
- Charger

## Plan
Leave early to beat the traffic.

Keep the receipts.

Stops:
1. Lyon
2. Turin

becomes this map:

Trip
├── Packing
│   ├── Passport
│   └── Charger
└── Plan
    ├── Leave early to beat the traffic.   (both paragraphs, one node)
    └── Stops:
        ├── Lyon
        └── Turin

Add a child named USB-C cable under Charger in the map, and the note gets it as a nested item:

- Charger
  - USB-C cable

• The heading level sets how deep a node is. When you move a node, the plugin updates the heading levels of the node and everything under it.
• If a note has more than one top-level heading, the map adds a root node named after the file.
• Paragraphs that follow one another are one node, which shows up to six lines of text; hover over it to see the rest. A list right after a paragraph becomes that paragraph's children.
• Tables, code blocks, quotes and embeds belong to the node before them and move with it.
• A node shows the first line of its content under its title.

Install

The plugin is not in the community directory yet. To install it manually:

1. Download main.js, manifest.json and styles.css from a release into <vault>/.obsidian/plugins/mdmap/, or build them from the source code directly into the vault (see Development).
2. Turn on mdmap in Settings → Community plugins.
3. Open a note and run Edit current note as mind map from the command palette. The map opens next to the note.

Keyboard and mouse

The command Copy current note as Mermaid mindmap copies the whole note to the clipboard as a Mermaid mindmap block.

Settings and details

List items and paragraphs as nodes (on by default, in Settings → mdmap). When it is off, only headings are nodes, and list items and paragraphs belong to the heading above them. The change applies the next time you open a mind map.

Show clicked node in the note (on by default, in the gear menu of the map's header). When it is off, clicking a node only selects it in the map.

Where positions are saved. When you drag a node to an empty part of the map, the plugin adds a comment block at the end of the note:

%% mindmap-positions
Pesquisa/Artigos: -54,149
%%

Each line has the node's path (the titles from the root down, separated by /) and its x,y distance from the top-left corner of its parent, so the node stays next to its parent when the parent moves. Obsidian hides %% comments in reading view. The plugin deletes the block when no node has a saved position, for example after you click Tidy tree.

Images and videos from the internet. If an embedded image or video links to an http:// or https:// address, the plugin downloads it from that address when it shows the node, so the server at that address receives a request from your computer. Images and videos stored in the vault are read from the vault.

Support mdmap

If mdmap is useful to you, you can support its development on GitHub Sponsors.

Development

git clone https://github.com/pererinha/mdmap.git
cd mdmap
npm install
npm run build     # builds main.js and styles.css; with MDMAP_VAULT=/path/to/vault it also copies the plugin into that vault
npm test          # unit tests for reading and writing Markdown, the layouts and the Mermaid export

To run tests in a real Obsidian app, see e2e/README.md.

Release

1. Set the new version in manifest.json and package.json, and describe the changes in CHANGELOG.md.
2. Push a tag with exactly that version and no v (1.0.1, not v1.0.1). Obsidian finds the release by this name.
3. The release workflow runs the tests, builds the plugin, and publishes main.js, manifest.json and styles.css in a GitHub release named after the tag.
