Usage

Initialise a new instance of the BTCAClient.

var BTCA = new BTCAClient({
  handle: 'MY_BTCA',      // unqiue handle to identify BTCA
  cache: false,           // caches requests (useful for debugging)
  disableEvents: false,   // disables default events (see below)
  log: false              // logs actions to console
});

Send Request

There are various ways to perform a JSBridge request.

// define your JSBridge action
var data = {
  action: 'getEntity',
  params: {
    entityName: 'story',
    id: 123
  }
};

// send with anonymous callback
BTCA.send(data, function(result, requestId, error) {
  console.log(result);
});

// send with callback reference
BTCA.send(data, handleRequestResponse);

// send with btcjsapi:// schema and named jsListener callback
BTCA.send('btcjsapi://getList?entityName=story&id=123&jsListener=handleRequestResponse')

Disabling Default Events

By default, JSBridge actions are bound to various anchor click events. If you'd like to disable this and handle it yourself you may set disableEvents: true when initialising.

• Anchor tags with mailto: are parsed and will send a sendMail action.
• Anchor tags with an absolute URL or rel=app are treated as Hub links and will send an openURL action.
• Anchor tags with an http(s) link or rel=external are treated as external links and will send an openURL action.
• Anchor tags with btcjsapi:// will send the specified action.
