Providing the Widget API to components

Now you can use it in your application:

import { WidgetApiImpl } from '@matrix-widget-toolkit/api';
import {
  MuiThemeProvider,
  MuiWidgetApiProvider,
} from '@matrix-widget-toolkit/mui';
import { Button } from '@mui/material';

// Initiate the widget API on startup. The Client will initiate
// the connection with `capabilities` and we need to make sure
// that the message doesn't get lost while we are initiating React.
const widgetApiPromise = WidgetApiImpl.create();

function App() {
  return (
    <MuiThemeProvider>
      <MuiWidgetApiProvider widgetApiPromise={widgetApiPromise}>
        <Button>A styled button</Button>
      </MuiWidgetApiProvider>
    </MuiThemeProvider>
  );
}

export default App;

Setup i18n

The matrix-widget-toolkit uses i18next to provide translations for messages. To make it work in your widget you have to initialize it on your end. See the i18next getting started documentation. This package provides a WidgetToolkitI18nBackend containing the translation data. You can use the ChainedBackend plugin to load translation data for the matrix-widget-toolkit together the translation data for the widget itself. The package provides a WidgetApiLanguageDetector that detects the language from the widget parameters with the i18next-browser-languagedetector plugin. For more details, see the implementation in the example widget.

Requesting capabilities on demand

You can hide child components till the user has approved all required capabilities:

import { MuiCapabilitiesGuard } from '@matrix-widget-toolkit/mui';
import { EventDirection, WidgetEventCapability } from 'matrix-widget-api';

<MuiCapabilitiesGuard
  capabilities={[
    WidgetEventCapability.forStateEvent(
      EventDirection.Receive,
      STATE_EVENT_ROOM_NAME,
    ),
  ]}
>
  /* Children are only displayed once the user has approved all capabilities. */
</MuiCapabilitiesGuard>;
