createCallObject()

createCallObject({properties})

Create a video call object as part of the current page's JavaScript environment (not isolated in an iframe).

This is an advanced usage of the react-native-daily-js API, and gives you raw access to MediaStreamTrack objects, and other WebRTC objects, for building custom video call experiences.

The argument is an optional properties object that configures call settings. These settings include:

url
token
subscribeToTracksAutomatically
reactNativeConfig
lang
receiveSettings

For full details on all the properties, see the properties list.

If you don't set at least the url property via createCallObject(), you'll need to set it later when you call the join() or load() method.

If you don't set at least the url property in this object, you'll need to set it later when you call the join() or load() method.

By default, only one call object instance is supported at a time and the constructor will throw an Error if multiple are detected. Starting in daily-js 0.67.0, multiple instances are supported on an opt in basis. To opt-in, setallowMultipleCallInstances to true in your factory method's properties. and checkout this guide for more information.
