Server-side output data source

An output data source may not save data in data source instance, but uses remote database, this is called a server-side output data source.

How to use the sample

Clone the sample repo and copy this widget's folder (within samples/widgets) to the client/your-extensions/widgets folder of your Experience Builder installation.

How it works

In setting.tsx, use DataSourceSelector to allow the user to select an origin data source. Declare the output data source inside onChange callback of DataSourceSelector.

// Let framework know which data source current widget is using and which data source current widget is the  output.
this.props.onSettingChange({
  id: this.props.id,
  useDataSources: useDataSources
}, outputDsJsons)

Select a filter and save it in widget config.

<SqlExpressionBuilderPopup
  dataSource={ds}
  mode={SqlExpressionMode.Simple}
  expression={this.props.config.sqlExpression}
  // use this.props.onSettingChange to save filter to config inside this callback
  onChange={this.onSqlExpressionChange}
  isOpen={this.state.isSqlBuilderOpen}
  toggle={this.toggleSqlBuilder}
/>

In widget.tsx, use DataSourceComponent to create origin data source instance. Update the output data source's query parameters every time the user clicks the update output data source button.

<Button onClick={this.updateOutputDsQueryParams}>
  Update output data source
</Button>

Please note this widget only generates an output data source. If you want to use the output data source, please add another widget (such as the List widget) and select the output data source for it. This sample widget does not listen to the origin data source change, you can use onDataSourceInfoChange callback of the DataSourceComponent to listen to the origin data source change.
