How can I configure indentation size in my Jupyter notebooks?

I'd like to have a default indentation size of 2 spaces instead of 4 spaces in my Jupyter notebooks. How can I do this?

Note: this is not a duplicate of How do I change the autoindent to 2 space in IPython notebook, as that question is for (deprecated) IPython notebooks and not (current) Jupyter notebooks.

The correct way to do this is in bpirvu's buried answer to How do I change the autoindent to 2 space in IPython notebook:

Just edit ~/.jupyter/nbconfig/notebook.json. Here is a complete notebook.json which includes the relevant setting:

{
  "CodeCell": {
    "cm_config": {
      "indentUnit": 2
    }
  }
}

There's also a more hacky solution that's more prevalent around the web, probably because the Jupyter documentation is lacking on this topic and indentUnit is only mentioned here: http://jupyter-notebook.readthedocs.io/en/latest/frontend_config.html. This solution is to open your browser's JavaScript console and enter

var cell = Jupyter.notebook.get_selected_cell();
var config = cell.config;
var patch = {
      CodeCell:{
        cm_config:{indentUnit:2}
      }
    }
config.update(patch)

which ends up editing ~/.jupyter/nbconfig/notebook.json for you.
