The JupyterLab Developer Guide is for developing JupyterLab extensions or developing JupyterLab itself.
The jupyterlab/jupyterlab repository contains two packages:
- an npm package indicated by a
package.jsonfile in the repo's root directory - a Python package indicated by a
setup.pyfile in the repo's root directory
The npm package and the Python package are both named jupyterlab.
See the Contributing Guidelines for developer installation instructions.

The examples/ directory contains stand-alone examples of components, such as a simple notebook on a page, a console, terminal, and a filebrowser. The lab example illustrates a simplified combination of components used in JupyterLab. This example shows multiple stand-alone components combined to create a more complex application.
The tests are stored and run in the test/ directory. The source files are in test/src/.
The jupyterlab/ directory contains the Jupyter server extension.
The server extension includes a private npm package in order to build the webpack bundle which the extension serves. The private npm package depends on the jupyterlab npm package found in the repo's root directory.
The git-hooks/ directory stores some convenience git hooks that automatically rebuild the npm package and server extension every time you check out or merge (via pull request or direct push to master) in the git repo.
After building the docs (jlpm run docs), docs/index.html is the entry point to the documentation.
