Add browser tab

The Universal Discovery Widget (UDW) is a separate React module. By default, it contains two tabs: Browse and Bookmarks.

Follow the instructions below to create and add a new tab called Images which displays all content items of the type 'Image'.

Create tab

First, in assets/js/image-tab/, add an image.tab.module.js file.

import React, { useContext } from 'react';

import Tab from '@ibexa-admin-ui/src/bundle/ui-dev/src/modules/universal-discovery/components/tab/tab';
import ImagesList from './components/images.list';

const ImageTabModule = () => {
    return (
        <div className="m-image-tab">
            <Tab isContentOnTheFlyDisabled={true} isSortSwitcherDisabled={true} isViewSwitcherDisabled={true}>
                <ImagesList />
            </Tab>
        </div>
    );
};

Next, add the tab to the configuration in the same file. Each tab definition is an object containing the following properties:

Property	Value	Definition
id	string	Tab ID, for example, image.
component	element	React component that represents the contents of a tab.
label	string	Label text, for example, Images.
icon	string	Path to the icon, for example, /bundles/ibexaadminui/img/ibexa-icons.svg#image.

ibexa.addConfig(
    'adminUiConfig.universalDiscoveryWidget.tabs',
    [
        {
            id: 'image',
            component: ImageTabModule,
            label: 'Image',
            icon: '/bundles/ibexaadminui/img/ibexa-icons.svg#image',
        },
    ],
    true
);

export default ImageTabModule;

The module governs the creation of the new tab.

Complete image.tab.module.js code

import React, { useContext } from 'react';

import Tab from '@ibexa-admin-ui/src/bundle/ui-dev/src/modules/universal-discovery/components/tab/tab';
import ImagesList from './components/images.list';

const ImageTabModule = () => {
    return (
        <div className="m-image-tab">
            <Tab isContentOnTheFlyDisabled={true} isSortSwitcherDisabled={true} isViewSwitcherDisabled={true}>
                <ImagesList />
            </Tab>
        </div>
    );
};
ibexa.addConfig(
    'adminUiConfig.universalDiscoveryWidget.tabs',
    [
        {
            id: 'image',
            component: ImageTabModule,
            label: 'Image',
            icon: '/bundles/ibexaadminui/img/ibexa-icons.svg#image',
        },
    ],
    true
);

export default ImageTabModule;

Add tab to webpack config

In webpack.config.js, add the following declaration:

const ibexaConfigManager = require('./ibexa.webpack.config.manager.js');

Next, provide configuration for the new module:

ibexaConfigManager.add({
    ibexaConfig,
    entryName: 'ibexa-admin-ui-udw-tabs-js',
    newItems: [path.resolve(__dirname, './assets/js/image-tab/image.tab.module.js')],
});

Provide ReactJS files

Next, you need to provide a set of files used to render the module:

• images.service.js handles fetching the images
• images.list.js renders the image list
• image.js renders a single image

images.service.js

Create a service for fetching the images by adding images.service.js to assets/js/image-tab/services/:

const handleRequestResponse = (response) => {
    if (!response.ok) {
        throw Error(response.statusText);
    }

    return response.json();
};

export const getImages = ({ token, siteaccess, contentId }, callback) => {
    const body = JSON.stringify({
        ViewInput: {
            identifier: 'images',
            public: false,
            LocationQuery: {
                Criteria: {},
                FacetBuilders: {},
                SortClauses: {},
                Filter: { ContentTypeIdCriterion: 5 },
            },
        },
    });
    const request = new Request('/api/ibexa/v2/views', {
        method: 'POST',
        headers: {
            Accept: 'application/vnd.ibexa.api.View+json; version=1.1',
            'Content-Type': 'application/vnd.ibexa.api.ViewInput+json; version=1.1',
            'X-Siteaccess': siteaccess,
            'X-CSRF-Token': token,
        },
        body,
        mode: 'cors',
    });

    fetch(request)
        .then(handleRequestResponse)
        .then(callback)
        .catch((error) => console.log('error:load:images', error));
};

export const loadImageContent = ({ token, siteaccess, contentId }, callback) => {
    const body = JSON.stringify({
        ViewInput: {
            identifier: `image-content-${contentId}`,
            public: false,
            ContentQuery: {
                Criteria: {},
                FacetBuilders: {},
                SortClauses: {},
                Filter: { ContentIdCriterion: contentId },
            },
        },
    });
    const request = new Request('/api/ibexa/v2/views', {
        method: 'POST',
        headers: {
            Accept: 'application/vnd.ibexa.api.View+json; version=1.1',
            'Content-Type': 'application/vnd.ibexa.api.ViewInput+json; version=1.1',
            'X-Siteaccess': siteaccess,
            'X-CSRF-Token': token,
        },
        body,
        mode: 'cors',
    });

    fetch(request)
        .then(handleRequestResponse)
        .then(callback)
        .catch((error) => console.log('error:load:images', error));
};

images.list.js

Next, create an image list by adding an images.list.js to assets/js/image-tab/components/:

import React, { useState, useContext, useEffect } from 'react';
import Image from './image';
import { getImages } from '../services/images.service';

import { RestInfoContext } from '@ibexa-admin-ui/src/bundle/ui-dev/src/modules/universal-discovery/universal.discovery.module';

const ImagesList = () => {
    const [images, setImages] = useState([]);
    const [page, setPage] = useState(0);
    const [itemsPerPage, setItemPerPage] = useState(5);
    const [maxPageIndex, setMaxPageIndex] = useState(0);
    const restInfo = useContext(RestInfoContext);
    const updateImagesState = (response) => {
        const images = response.View.Result.searchHits.searchHit.map((item) => item.value.Location);
        const modulo = images.length % itemsPerPage;
        const maxPageIndex = modulo ? (images.length - modulo) / itemsPerPage : images.length / itemsPerPage - 1;

        setImages(images);
        setMaxPageIndex(maxPageIndex);
    };
    const showPrevPage = () => {
        const prevPage = page > 0 ? page - 1 : 0;

        setPage(prevPage);
    };
    const showNextPage = () => {
        const nextPage = maxPageIndex > page ? page + 1 : maxPageIndex;

        setPage(nextPage);
    };
    const renderItems = () => {
        const attrs = {
            className: 'c-images-list__items',
            style: {
                transform: `translate3d(-${page * itemsPerPage * 316}px, 0, 0)`,
            },
        };

        return (
            <div className="c-images-list__items-wrapper">
                <div {...attrs}>
                    {images.map((imageLocation) => (
                        <Image key={imageLocation.id} location={imageLocation} restInfo={restInfo} />
                    ))}
                </div>
            </div>
        );
    };
    const renderPrevBtn = () => {
        const attrs = {
            className: 'c-images-list__btn--prev',
            onClick: showPrevPage,
        };

        if (page <= 0) {
            attrs.disabled = true;
        }

        return (
            <div {...attrs}>
                <svg className="ibexa-icon">
                    <use xlinkHref={window.ibexa.helpers.icon.getIconPath('caret-back')}></use>
                </svg>
            </div>
        );
    };
    const renderNextBtn = () => {
        const attrs = {
            className: 'c-images-list__btn--next',
            onClick: showNextPage,
        };

        if (page >= maxPageIndex) {
            attrs.disabled = true;
        }

        return (
            <div {...attrs}>
                <svg className="ibexa-icon">
                    <use xlinkHref={window.ibexa.helpers.icon.getIconPath('caret-next')}></use>
                </svg>
            </div>
        );
    };

    useEffect(() => {
        getImages(restInfo, updateImagesState);
    }, []);

    return (
        <div className="c-images-list">
            {renderPrevBtn()}
            {renderItems()}
            {renderNextBtn()}
        </div>
    );
};

export default ImagesList;

image.js

Finally, create an image view by adding an image.js to assets/js/image-tab/components/:

import React, { useState, useEffect, useContext } from 'react';
import { loadImageContent } from '../services/images.service';
import {
    MarkedLocationIdContext,
    LoadedLocationsMapContext,
    MultipleConfigContext,
    SelectedLocationsContext,
} from '@ibexa-admin-ui/src/bundle/ui-dev/src/modules/universal-discovery/universal.discovery.module';
const Image = ({ restInfo, location }) => {
    const [content, setContent] = useState(null);
    const [markedLocationId, setMarkedLocationId] = useContext(MarkedLocationIdContext);
    const [loadedLocationsMap, dispatchLoadedLocationsAction] = useContext(LoadedLocationsMapContext);
    const [selectedLocations, dispatchSelectedLocationsAction] = useContext(SelectedLocationsContext);
    const [multiple] = useContext(MultipleConfigContext);
    const updateVersionInfoState = (response) => {

        setContent(response.View.Result.searchHits.searchHit[0].value.Content);
    };
    const markLocation = ({ nativeEvent }) => {
        const isMarkedLocationClicked = location.id === markedLocationId;

        if (isMarkedLocationClicked) {
            return;
        }

        setMarkedLocationId(location.id);
        dispatchLoadedLocationsAction({ type: 'CUT_LOCATIONS', locationId: location.id });
        dispatchLoadedLocationsAction({ type: 'UPDATE_LOCATIONS', data: { parentLocationId: location.id, subitems: [] } });

        if (!multiple) {
            dispatchSelectedLocationsAction({ type: 'CLEAR_SELECTED_LOCATIONS' });
                dispatchSelectedLocationsAction({ type: 'ADD_SELECTED_LOCATION', location });
        }
    };

Add styles

Ensure that the new tab is styled by adding the following files to assets/css/.

images.list.css

.c-images-list {
    display: grid;
    grid-template-areas: 'prev list next';
    grid-template-columns: 32px 1fr 32px;

.c-image:hover:before,
.c-image:focus:before {
    opacity: 1;
}

.c-image__thumb {
    display: block;
    max-width: 300px;
    max-height: 200px;
    width: auto;
    height: auto;
    margin: auto;
}

Add css to webpack

Finally, add css in webpack.config.js:

ibexaConfigManager.add({
    ibexaConfig,
    entryName: 'ibexa-admin-ui-layout-css',
    newItems: [path.resolve(__dirname, './assets/css/image.css'), path.resolve(__dirname, './assets/css/image.list.css')],
});

Check results

In the Back Office go to Content -> Dashboard. On the top right, click the Create content button. In the UDW a new Images tab appears, listing all images from the Repository.

Tip

If you cannot see the results or encounter an error, clear the cache and reload the application. Remember, after any change of css/js files you should always run yarn encore dev in the terminal.
