Jupyter Server Proxy lets you run arbitrary external processes (such as
RStudio, Shiny Server, Syncthing, PostgreSQL, Code Server, etc)
alongside your notebook server and provide authenticated web access to
them using a path like `/rstudio` next to others like `/lab`. Alongside
the python package that provides the main functionality, the JupyterLab
extension (`@jupyterhub/jupyter-server-proxy`) provides buttons in the
JupyterLab launcher window to get to RStudio for example.

**Note:** This project used to be called **nbserverproxy**. As
nbserverproxy is an older version of jupyter-server-proxy, uninstall
nbserverproxy before installing jupyter-server-proxy to avoid conflicts.

The primary use cases are:

1.  Use with JupyterHub / Binder to allow launching users into web
    interfaces that have nothing to do with Jupyter - such as RStudio,
    Shiny, or OpenRefine.
2.  Allow access from frontend javascript (in classic notebook or
    JupyterLab extensions) to access web APIs of other processes running
    locally in a safe manner. This is used by the [JupyterLab
    extension](https://github.com/dask/dask-labextension) for
    [dask](https://www.dask.org/).

[The documentation](https://jupyter-server-proxy.readthedocs.io/)
contains information on installation & usage.

## Security warning

Jupyter Server Proxy is often used to start a user defined process listening to
some network port (e.g. `http://localhost:4567`) for a user starting a Jupyter Server
that only that user has permission to access. The user can then access the
started process proxied through the Jupyter Server.

For safe use of Jupyter Server Proxy, you should ensure that the process started
by Jupyter Server proxy can't be accessed directly by another user and bypass
the Jupyter Server's authorization!

A common strategy to enforce access proxied via Jupyter Server is to start
Jupyter Server within a container and only allow network access to the Jupyter
Server via the container.

> For more insights, see [Ryan Lovett's comment about
> it](https://github.com/jupyterhub/jupyter-server-proxy/pull/359#issuecomment-1350118197).

## Install

### Python package

#### `pip`

```bash
pip install jupyter-server-proxy
```

#### `conda`

```bash
conda install -c conda-forge jupyter-server-proxy
```

### Jupyter Client Extensions

A JupyterLab and Notebook extension is bundled with the Python package to
provide:

- servers in the _New_ dropwdown of the Notebook Tree view
- launch buttons in JupyterLab's Launcher panel for registered server processes.
  - ![a screenshot of the JupyterLab Launcher](docs/source/_static/images/labextension-launcher.png "launch proxied servers as JupyterLab panels or new browser tabs")

#### Client compatibility

For historical compatibility ranges, see the table below:

| `jupyter-server-proxy` | `notebook` | `jupyterlab` |
| :--------------------: | :--------: | :----------: |
|        `4.1.x`         |  `>=6,<8`  |   `>=3,<5`   |
|        `4.0.x`         |  `>=6,<7`  |   `>=3,<4`   |
|         `3.x`          |  `>=6,<7`  |   `>=2,<4`   |

## Disable

### Server extension

```bash
jupyter serverextension disable --sys-prefix jupyter_server_proxy
jupyter server extension disable --sys-prefix jupyter_server_proxy
```

### Notebook Classic extension

```bash
jupyter nbextension disable --sys-prefix --py jupyter_server_proxy
```

### JupyterLab extension

```bash
jupyter labextension disable @jupyterhub/jupyter-server-proxy
```
