Référence API micro front-end

API microfrontend SDK

action: Type
{reload?: typeof window.location.reload}
Description
Used to pass a callback to reload the page: { reload } . To use this prop, integrateActions must be set to true.
auth: Type
{ accessToken, idToken, userInfo {OidcUserInfo | null} }
Description
Used to pass an object with tokens and userInfo: { accessToken, idToken, userInfo } to make these values available in the micro frontend. To use this prop, integrateAuthmust be set to true and it is mandatory if integrateAuth is enabled.
configOverrides: Type
{ customConfig: string, localeSettings: {} }
Description
Allows the shell app to inject custom configurations into the micro frontend's Jutro config object.

When the JUTRO_NEW_CONFIG_LOADING_ORDER environment variable is set to true, the config object has precedence over values in the .env file. In the shell app, you can then use configOverrides to inject the values in the config object and they are applied to the micro frontend's configuration.

When the JUTRO_NEW_CONFIG_LOADING_ORDER environment variable is set to false, the .env file has precedence over the Jutro config object. configOverrides can still inject values into the Jutro config object, but they're not visible if the same variables are also defined in the .env file.
g11n: Type
LocaleConfig, 'onGlobalizationChange( language?: string; languageChanged?: boolean; locale: string; localeChanged: boolean )'
Description
Allows you to pass locale configuration. To use this prop, integrateG11n must be set to true.
iframeAttributes: Type
{allow?: string; referrerpolicy?: string; sandbox?: string}
Description
Allows to pass additional attributes for micro frontends. Entries from iframeAttributes prop are added to the iframe HTML element.
integrateActions: Type
boolean
Description
Lets the shell know when reloading on the micro frontend side. When set to true, you must also pass the action prop to enable the actions integration.
integrateAuth: Type
boolean
Description
Allows the sharing of authentication information between the shell app and the micro frontend. When set to true, you must also pass the auth prop to enable the authentication integration.
integrateG11n: Type
boolean
Description
Allows you to listen to globalization changes in the micro frontend. When set to true, you must also pass the g11n prop to enable the globalization integration.
integrateJutro: Type
boolean
Description
Enables or disables the rest of integrate* props. By default is set to false. All the integrate* props inherit the integrateJutro value, this means that when it is set to true the rest of the integrate* props are set to true. Then each of the props value can be manually overridden.
integrateModal: Type
boolean
Description
Enables the modal integration to trigger a modal from within the micro frontend so it can be displayed by the shell app. When set to true, you must also pass the modal prop to enable the modal integration.
integrateRouter: Type
boolean
Description
Allows the router prop integration. When set to true, you must also pass the router prop to enable router integration.
integrateTheme: Type
boolean
Description
Allows you to set the theme that the micro frontend uses. Once enabled, use the prop theme to specify the theme to use. When set to true, you must also pass the theme prop to enable the theme integration.
integrateToast: Type
boolean
Description
Enables the toast integration to trigger a toast message from within the micro frontend so it can be displayed by the shell app. When set to true, you must also pass the toast prop to enable the toast integration.
modal: Type
{ showAlert, showConfirm }
Description
Triggers a modal from within the micro frontend so it can be displayed by the shell app. It is an object with modal property with a callback value. To use this prop, integrateModal must be set to true.
onError: Type
({ error: Error, errorInfo?:ErrorInfo }) => void
Description
A callback to invoke when an error occurs. See the Microfrontend SDK documentation for more details about this property.
onLoadingFinished: Type
() => void
Description
Allows consumers to trigger a callback when a micro frontend finishes loading, enabling them to display their own loader from the shell app for a seamless integration.
onRender: Type
func
Description
A function that is called when the micro frontend is rendered or updated.
router: Type
{location?: string; state?: unknown; onLocationChange?(pathname?: string; action?: 'PUSH' | 'REPLACE' | 'GO'; state?: unknown ) => void; basename?: string; onBlockChange(isBlocked: boolean; prompt?: never)}
Description
Sets the current location of the micro frontend. Any change triggers the navigation on the micro frontend side.
theme: Type
{themeConfig?: ThemeConfigType;}
Description
Sets the theme that the micro frontend uses. To use it, integrateTheme must be set to true.
timeout: Type
number
Description
The app waits the specified time in milliseconds for the micro frontend to load. Note: Network errors such as net::ERR_CONNECTION_REFUSED get handled at the browser level. As there is no API to detect it, the only way to identify the error is to wait until the timeout handler shows an error view. Developers can identify the error in the Network tab of Developer Tools.
toast: Type
{ message?: IntlMessageShape; type?: 'info' | 'success' | 'warning' | 'error'; autoFocus?: boolean; linkProps?: LinkProps; onClosed?: ToastOptions['onClose']; toastId?: string; }
Description

jutro: {
    integrateJutro: true,
    auth: authProps,
    router: {
        location: route,

            if (action === 'PUSH') {
                history.push({
                    pathname: urlBase + location,
                });
            }

    theme: {
        themeConfig,
        switchTheme,
    },
    toast: {
        toast: ({ message }) => {
            const elementToHoldToastMessage =
                document.getElementById('toastMessage');

            if (elementToHoldToastMessage) {
                elementToHoldToastMessage.innerText = message;
            }
        },
    },
    configOverrides: {
        customConfig: 'Micro-app overridden configuration',
        localeSettings: {
            availableLocales: ['en-US', 'es-ES'],
            preferredLanguage: 'ES',
            defaultCurrency: 'EUR',

        console.error(error);
        console.error(errorInfo);
    }
