# jupyterlab-snapshot
A JupyterLab extension.
This extension is composed of a Python package named jupyterlab-snapshot for the server extension and a NPM package named jupyterlab-snapshot for the frontend extension.
## Requirements
JupyterLab >= 3.0
## Install
`bash pip install jupyterlab-snapshot `
## Troubleshoot
If you are seeing the frontend extension, but it is not working, check that the server extension is enabled:
`bash jupyter server extension list `
If the server extension is installed and enabled, but you are not seeing the frontend extension, check the frontend extension is installed:
`bash jupyter labextension list `
## Contributing
### Development install
Note: You will need NodeJS to build the extension package.
The jlpm command is JupyterLab’s pinned version of [yarn](https://yarnpkg.com/) that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.
`bash # Clone the repo to your local environment # Change directory to the jupyterlab-snapshot directory # Install package in development mode pip install -e . # Link your development version of the extension with JupyterLab jupyter labextension develop . --overwrite # Rebuild extension Typescript source after making changes jlpm run build `
You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension’s source and automatically rebuild the extension.
`bash # Watch the source directory in one terminal, automatically rebuilding when needed jlpm run watch # Run JupyterLab in another terminal jupyter lab `
With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).
By default, the jlpm run build command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:
`bash jupyter lab build --minimize=False `
### Uninstall
`bash pip uninstall jupyterlab-snapshot `
