Hi Thirasu,
The above information is still not added to the docs.
The functionality behind this is to create a WebSocket connection to the
data-provider endpoint with a required configuration. The
documentation @Sajith pointed out has the details on various data provider
endpoints and the configurations.
You have to do the following steps,
1. Access data provider configurations in widgetConf.json file [1]
2. Use the base widget API to create WebSocket connection. For this, you
can use the following APIs,
- Subscribe to the endpoint:
- syntax : super.getWidgetChannelManager().subscribeWidget(<Widget
id>, <Call back method to handle data>, <data provider configs>)
- Example:
-
super.getWidgetChannelManager()
.subscribeWidget(this.props.id, this.handleDataReceived,
dataProviderConfigs));
- Unsubscribe to the endpoint
- syntax: super.getWidgetChannelManager().unsubscribeWidget(<Widget
ID>);
- Example:
-
super.getWidgetChannelManager().unsubscribeWidget(this.props.id);
@Nisala Nanayakkara <[email protected]> Please add anything I have missed.
@Rukshani Weerasinha <[email protected]> Shall we add the above to the
documentation, as this will be a blocker to anyone writing custom widgets.
