This is a [SaltyRTC](https://saltyrtc.org/) Relayed Data task implementation for
JavaScript (ES5 / ES2015), written in TypeScript.

> :warning: **Note:** The SaltyRTC client libraries are in maintenance mode.
> They will still receive bugfixes and regular maintenance, but if you want to
> start using these libraries, be prepared that you will need to take over
> maintenance at some point in time. (If you are interested in maintaining the

## Installing

### Via npm

You can install this library (and its peer dependencies) via `npm`:

    npm install --save @saltyrtc/task-relayed-data @saltyrtc/client tweetnacl msgpack-lite


## Usage

Create a new task instance:

    const task = new RelayedDataTask();

(If you want to enable debug console messages, you can pass `true` to the constructor:)

    const task = new RelayedDataTask(true);

Once the connection is established (when the `SaltyRTC` instance raises the
`state-change:task` event), you can send messages using the `sendMessage` method:

    task.sendMessage("hello");
    task.sendMessage({"type": "custom", "value": "You can also send objects"});

When a new message arrives from the peer, an event is emitted. You can register
and deregister event handlers with the `on`, `once` and `off` methods:

    task.on('data', (ev) => {
        console.log('New data message arrived:', ev.data);
    });

The following events are available:

* `data`: A new message from the peer was received.


## Testing

To run tests:

    npm run build_tests

Then open `tests/testsuite.html` in your browser.

To run linting checks:

    npm run lint

You can also install a pre-push hook to do the linting:

    echo -e '#!/bin/sh\nnpm run lint' > .git/hooks/pre-push
    chmod +x .git/hooks/pre-push
