Customizing Settings

With the CLI, if you create an {lite-dir}/overrides.json in either the root, or a specific {lite-dir}/{app}/ directory, these will be merged into {output-dir}/{app?/}jupyter-lite.json#/jupyter-config-data/settingsOverrides.

Examples

Customize the REPL app

Let’s say you would like to customize the behavior of the REPL app, and use the terminal interaction mode.

You can create the following overrides.json in {lite-dir}/repl/ before building:

{
  "@jupyterlab/console-extension:tracker": {
    "interactionMode": "terminal"
  }
}

One of the effects of using terminal for the interactionMode will be the switch from Shift-Enter to Enter for executing code.

Add a download button in the notebook menu bar

If you want to add a download button in the notebook menu bar, you can add the following lines in overrides.json:

{
  "@jupyterlab/notebook-extension:panel": {
    "toolbar": [
      {
        "name": "download",
        "label": "Download",
        "args": {},
        "command": "docmanager:download",
        "icon": "ui-components:download",
        "rank": 50
      }
    ]
  }
}

You will now have a menu bar similar to the one below:
