Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including markmap with all npm packages installed. Try it out:

markmap lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("markmap/[??]")

  • Zoom in and out with the mouse wheel.
  • Pan around by dragging the backgroud.
  • Expand/collapse children of a node by clicking on the circle.

Supported formats:

  • Markdown
  • MindMup
  • Txtmap (whitespace indented plaintext)
  • Pandoc (limited prototype)

Suggestions for new featues are welcome, feel free to open an issue.

How to use

Install the component with NPM:

npm install markmap

Visualizing a markdown text consists of two steps:

  1. The text is parsed and transformed into a tree representation.
  2. The tree is rendered.


To run the examples first clone the project and install dependencies:

git clone
cd markmap
npm install

In the examples code there are imports like require('../../lib/somefile'). When using this library in your project you need to change those to require('markmap/lib/somefile').


Run npm start and a browser will open with the example page where you can see how different formats are parsed and displayed. The source code for browser examples is located in examples/browser folder.


Node examples are located in examples/node. You can run the markdown example or others as follows:

cd examples/node
node example.markdown.js
