## Requirements

- `python >=3.7`
- `jupyterlab ==3.*`

## Install

Install the server extension and JupyterLab extension with `pip`:

```bash
pip install -U jupyter-videochat
```

...or `conda`/`mamba`:

```bash
conda install -c conda-forge jupyter-videochat
```

## Usage

> See the [Jitsi Handbook] for more about using the actual chat once launched.

### View the Room List

#### JupyterLab

- From the _Main Menu_...
  - Click _File ▶ New ▶ Video Chat_
- From the _Launcher_...
  - Open a new _JupyterLab Launcher_
  - Scroll down to _Other_
  - Click the _Video Chat_ launcher card

#### RetroLab

- From the _Main Menu_...
  - Click _File ▶ New ▶ Video Chat_
- From the RetroLab File Tree...
  - Click the _New Video Chat_ button

### Start a Chat

- Provide your name and email (optional)
  - these will be saved in JupyterLab user settings for future usage
  - your email will be used to provide [Gravatar](https://gravatar.com) icon
- From one of the room _providers_, choose a room.
  - You may need to provide a room name

### Stop a Chat

- From the the Jitsi IFrame:
  - Click the red "hang up" button, or
- From the _Video Chat toolbar_
  - Click the _Disconnect Video Chat_ button

## Troubleshoot

> If the Jitsi frame actually loads, the [Jitsi Handbook] is the best source for more
> help.

### I see the Lab UI, but the video chat IFrame doesn't load

Sometimes the Jitsi IFrame runs into issues, and just shows a white frame.

_Try reloading the browser._

### I see the UI but I'm missing rooms

If you are seeing the frontend extension but it is not working, check that the server
extension is enabled:

```bash
jupyter server extension list
jupyter server extension enable --sys-prefix --py jupyter_videochat
```

... and restart the server.

> If you launch your Jupyter server with `jupyter notebook`, as Binder does, the
> equivalent commands are:
>
> ```bash
> jupyter serverextension list
> jupyter serverextension enable --sys-prefix --py jupyter_videochat
> ```

If the server extension is installed and enabled but you are not seeing the frontend,
check the frontend is installed:

```bash
jupyter labextension list
```

If you do not see `jupyterlab-videochat`, the best course of action is to
[uninstall](#uninstall) and [reinstall](#install), and carefully watch the log output.

## Architecture

This extension is composed of:

- a Python package named `jupyter_videochat`, which offers:
  - a `jupyter_server` extension which provides convenient, configurable defaults for
    rooms on a [JupyterHub]
  - a JupyterLab _pre-built_ or _federated extension_ named `jupyter-videochat`
    - also distributed on [npm]
      - for more about the TypeScript/JS API, see [CONTRIBUTING]
    - at JupyterLab runtime, some _Plugins_ which can be independently disabled
      - `jupyterlab-videochat:plugin` which is required by:
      - `jupyterlab-videochat:rooms-server`
      - `jupyterlab-videochat:rooms-public`
      - `jupyterlab-videochat:toggle-area`

## Configuration

### Server Configuration

In your `jupyter_server_config.json` (or equivalent `.py` or `conf.d/*.json`), you can
configure the `VideoChat`:

- `room_prefix`, a prefix used for your group, by default a URL-frieldy version of your
  JupyterHub's hostname
  - can be overriden with the `JUPYTER_VIDEOCHAT_ROOM_PREFIX` environment variable
- `jitsi_server`, an HTTPS host that serves the Jitsi web application, by default
  `meet.jit.si`
- `rooms`, a list of Room descriptions that everyone on your Hub will be able to join

#### Example

```json
{
  "VideoChat": {
    "room_prefix": "our-spiffy-room-prefix",
    "rooms": [
      {
        "id": "stand-up",
        "displayName": "Stand-Up",
        "description": "Daily room for meeting with the team"
      },
      {
        "id": "all-hands",
        "displayName": "All-Hands",
        "description": "A weekly room for the whole team"
      }
    ],
    "jitsi_server": "jitsi.example.com"
  }
}
```

### Client Configuration

In the JupyterLab _Advanced Settings_ panel, the _Video Chat_ settings can be further
configured, as can a user's default `displayName` and `email`. The defaults provided are
generally pretty conservative, and disable as many third-party services as possible.

Additionally, access to **globally-accessible** public rooms may be enabled.

#### Binder Client Example

For example, to enable all third-party features, public rooms, and open in the `main`
area by default:

- create an `overrides.json`

  ```json
  {
    "jupyter-videochat:plugin": {
      "interfaceConfigOverwrite": null,
      "configOverwrite": null,
      "disablePublicRooms": false,
      "area": "main"
    }
  }
  ```

- Copy it to the JupyterLab settings directory

  ```bash
  # postBuild
  mkdir -p ${NB_PYTHON_PREFIX}/share/jupyter/lab/settings
  cp overrides.json ${NB_PYTHON_PREFIX}/share/jupyter/lab/settings
  ```

#### JupyterLite Client Example

> Note: _JupyterLite_ is still alpha software, and the API is likely to change.

`jupyter lite build`

`jupyter_lite_config_.json`

```json
{
  "LabBuildConfig": {
    "federated_extensions": ["https://pypi.io/.../jupyterlab-videochat-0.6.0.whl"]
  }
}
```

Add a runtime `jupyter-lite.json` (or a build time `overrides.json`) to disable server
rooms.

```json
{
  "jupyter-lite-schema-version": 0,
  "jupyter-config-data": {
    "disabledExtensions": ["jupyterlab-videochat:rooms-server"],
    "settingsOverrides": {
      "jupyterlab-videochat:plugin": {
        "disablePublicRooms": false
      }
    }
  }
}
```

This can then be tested with:

```bash
jupyter lite serve
```

### Start a Meet by URL

Appending `?jvc=room-name` to a JupyterLab URL will automatically open the Meet (but not
_fully_ start it, as browsers require a user gesture to start audio/video).

#### Binder URL Example

On [Binder](https://mybinder.org), use the `urlpath` to append the argument, ensuring
the arguments get properly URL-encoded.

```
https://mybinder.org/v2/gh/jupyterlab-contrib/jupyter-videochat/demo?urlpath=tree%3Fjvc%3DStand-Up
                                                         # URL-encoded  [? ] [=  ]
```

##### nbgitpuller

If you have two repos (or branches) that contain:

- content that changes frequently
- a stable environment

...you can use [nbgitpuller](https://jupyterhub.github.io/nbgitpuller/link) to have
fast-building, (almost) single-click URLs that launch right into JupyterLab showing your
meeting and content. For example, to use...

- the [Python Data Science Handbook] as `master`
- this project's repo, at `demo` (_not recommended, as it's pretty
  [minimal][binder-reqs]_)

...and launch directly into JupyterLab showing

- the _Preface_ notebook
- the _Office Hours_ room

...the doubly-escaped URL would be something like:

```
https://mybinder.org/v2/gh/jupyterlab-contrib/jupyter-videochat/demo?
urlpath=git-pull
  %3Frepo%3Dhttps%253A%252F%252Fgithub.com%252Fjakevdp%252FPythonDataScienceHandbook
  %26branch%3Dmaster
  %26urlpath%3Dlab%252Ftree%252FPythonDataScienceHandbook%252Fnotebooks%252F00.00-Preface.ipynb
  %253Fjvc%253DOffice%2BHours
```

#### JupyterLite Example

Additionally, `?JVC-PUBLIC=a-very-long-and-well-thought-key` can be enabled, providing a
similar experience, but for unobfuscated, publicly-visible rooms. **Use with care**, and
as a moderator take additional whatever steps you can from within the Jitsi security UI,
including:

- _lobbies_
- _passwords_
- _end-to-end encryption_

Once properly configured above, a JupyterLite site can be `git push`ed to GitHub Pages,
where a URL is far less obfuscated.

```
https://example.github.io/my-repo/lab?JVC-PUBLIC=a-very-long-and-well-thought-key
```

- probably _don't_ click on links shorter than about ten characters

## Uninstall

```bash
pip uninstall jupyter-videochat
```
