InitialSetup:

Data for widgets should be provided as part of the initialSetup response. The following keys should be added (also see the example below)

• widgets: "NewTab Messages".Widgets
• widgetConfigs: "NewTab Messages".WidgetConfigs

widgets

This specifies which individual features will be present on the page. Some widgets may be initially hidden, waiting for data.

The following example will cause all 3 widgets to register in the page (potentially creating side effects).

[
    { "id": "rmf" },
    { "id": "favorites" },
    { "id": "privacyStats" }
]
Copy

The id field maps to a JavaScript file in the entry-points folder. For example, { id: "rmf" } will cause the module entry-points/rmf.js to register

widgetConfigs

This provides the visibility (and other config in the future) of widgets that can be configured by the user. That's why it's normal for the widgets and widgetConfigs arrays to be different, for example:

{
  "...": "...",
  "widgets": [
    { "id": "rmf" },
    { "id": "favorites" },
    { "id": "privacyStats" }
  ],
  "widgetConfigs": [
    { "id": "favorites", "visibility": "visible" },
    { "id": "privacyStats", "visibility": "hidden" }
  ]
}
Copy

Subscriptions:

• widgets_onConfigUpdated
• returns "NewTab Messages".WidgetConfigs.

Notifications:

• widgets_setConfig

• sends "NewTab Messages".WidgetConfigs

  If the user toggles the visibility of a section in the frontend, then the entire structure is sent to the native side.

Examples:

The following examples show the data types in JSON format: messages/new-tab/examples/stats.js
