# Junction

Connect people through any URL.

Junction is a web extension for Firefox, Chrome and Safari that lets you start
an audio call at any URL.

## Building

Running `make` or `make package` will regenerate the content script, and
package the extension for all browsers in the `./build/` directory with
the following outputs:

- `junction.xpi`: The firefox extension
- `junction.zip`: The chrome extension
- `Junction.app`: The safari extension app

## Developing

The project is divided into three main parts:

- `server`: A server that handles message passing to establish the WebRTC
  connections.
- `extension`: The main code of the extension itself.
- `safari`: The safari app, it wraps the extension using symlinks.

### Dependencies

- `make` to run the build commands.
- `xcode` to build the safari extension.
- `node` and `pnpm` to build the extension, and if you want to run the server
  directly.
- `podman` and `podman-compose` if you want to run the server as a container.
- `prettier` to format Javascript, JSON, Yaml, and Markdown.
- `xcbeautify` to format swift

### Server

The server is a socket.io server that relays messages between peers to help
establish a WebRTC connection.

#### Configuration

You can use environment variables to control the server.

- `JUNCTION_SERVER_PORT` which port to listen on. Defaults to `8000`.

### Extension

The extension uses WebExtension manifest v2 and is compatible with Firefox,
Chrome and Safari.

You can build all extensions using `make` in the root of the directory.

If you want to run manually then you can run `pnpm install` from the
`extension` folder to install dependencies, and `pnpm build` to generate the
content script.

```
$ pnpm install && pnpm build
```

#### Testing on Firefox

In order to test on firefox, first go to `about:debugging`, then click
on the `This Firefox` option. Then click on `Load Temporary Add-On` and
point the browser to the `build/junction.xpi` file if you're using `make`, or
`extension/manifest.json` file if you're testing without packaging.

This will enable the extension and will allow you to use the inspector to
debug.

#### Testing on Chrome

In order to test on chrome, first go to `chrome://extensions/`. Make sure
`Developer mode` is enabled. You can drag the `build/junction.zip` file or
click `Load Unpacked` and point the browser to the `extension` directory.

#### Testing on Safari

Open `Junction.app` and then enable the extension in Safari.

### Formatting

Running `make format` will format the code with prettify and xcbeautify
