Get Started

Installation

To get the SDK into your project with NPM:

npm install @bloomreach/react-sdk

And with Yarn:

yarn add @bloomreach/react-sdk

Usage

The following code snippet renders a simple page with a Banner component.

import React from 'react';
import axios from 'axios';
import { BrComponent, BrPage, BrPageContext, BrProps } from '@bloomreach/react-sdk';

function Banner({ component }: BrProps) {
  return <div>Banner: {component.getName()}</div>;
}

export default function App() {
  const configuration = { /* ... */ };

  return (
    <BrPage configuration={configuration} mapping={{ Banner }}>
      <header>
        <BrPageContext.Consumer>
          { page => <Link to={page.getUrl('/')} />Home</Link> }
        </BrPageContext.Consumer>
        <BrComponent path="menu"><Menu /></BrComponent>
      </header>
      <section>
        <BrComponent path="main" />
      </section>
      <BrComponent path="footer">
        <footer><BrComponent /></footer>
      </BrComponent>
    </BrPage>
  );
}

Non-blocking render mode (NBRMode)

Non-blocking rendering mode can be used to decrease the time for your application to load fully on the client side. By default the NBRMode configuration is false to avoid breaking existing setups. Setting it to true will enable non-blocking render mode. When the mode is active the children of the BrPage component will start mounting while the Page Model is being fetched. These children might contain logic themselves that queries some external API and using non-blocking render mode would allow this to be executed in parallel to requesting the Page Model.

const fetchData = async () => {
  const data = await fetch('https://yourapi.com');
}

function MyComponent() {
  useEffect(() => {
    // This will run in parallel to fetching the PageModel from the Delivery API
    fetchData().catch(console.error);
  }, []);
  
  return `<div>Hello</div>`
}

export default function App() {
  const configuration = {
    /* ... */
    NBRMode: true,
  };

  return (
    <BrPage configuration={configuration} mapping={{ ... }}>
      <MyComponent/>
    </BrPage>
  );
}

Configuration

The BrPage component supports several options you may use to customize page initialization. These options will be passed to the initialize function from @bloomreach/spa-sdk. See here for the full configuration documentation in the SPA SDK Typedocs.

Mapping

The BrPage component provides a way to link React components with the brXM ones. It requires to pass the mapping property that maps the component type with its representation.

The Container Items can be mapped by their labels.

import NewsList from "./components/NewsList";

return <BrPage mapping={{ "News List": NewsList }} />;

The Containers can be only mapped by their type, so you need to use constants from @bloomreach/spa-sdk. By default, the React SDK provides an implementation for all the container types as it's defined in the documentation.

import { TYPE_CONTAINER_INLINE } from "@bloomreach/spa-sdk";
import MyInlineContainer from "./components/MyInlineContainer";

return <BrPage mapping={{ [TYPE_CONTAINER_INLINE]: MyInlineContainer }} />;

From within the Container component, the Container Items can be accessed via the children property. This can be used to reorder or wrap child elements.

export default function MyInlineContainer() {
  return (
    <div>
      {React.Children.map(props.children, (child) => (
        <span className="float-left">{child}</span>
      ))}
    </div>
  );
}

The Components can be mapped by their names. It is useful for a menu component mapping.

import Menu from "./components/Menu";

return <BrPage mapping={{ menu: Menu }} />;

By default, container items that are not mapped will be rendered as a warning text. There is an option to override the fallback.

import { TYPE_CONTAINER_ITEM_UNDEFINED } from "@bloomreach/spa-sdk";
import Fallback from "./components/Fallback";

return <BrPage mapping={{ [TYPE_CONTAINER_ITEM_UNDEFINED]: Fallback }} />;

Inline Mapping

There is also another way to render a component. In case you need to show a static component or a component from the abstract page, you can use inline component mapping.

return (
  <BrComponent path="menu">
    <Menu />
  </BrComponent>
);

It is also possible to point where the component's children are going to be placed.

return (
  <BrComponent path="footer">
    <footer>
      <BrComponent />
    </footer>
  </BrComponent>
);

The component data in case of inline mapping can be accessed via the BrComponentContext.

return (
  <BrComponentContext.Consumer>
    {(component) => (
      <BrComponent path="footer">
        <footer>
          &copy; {component.getName()}
          <BrComponent />
        </footer>
      </BrComponent>
    )}
  </BrComponentContext.Consumer>
);

Or by using React Hooks.

import { BrComponentContext } from "@bloomreach/react-sdk";

export default function Menu() {
  const component = React.useContext(BrComponentContext);

  return <ul>{component.getName()}</ul>;
}

Buttons

It is recommended to add the css style position: relative to the Buttons so they will position correctly within their parent container component.

Manage menu button can be placed inside a menu component using BrManageMenuButton component.

import React from "react";
import { Menu, Reference } from "@bloomreach/spa-sdk";
import {
  BrComponentContext,
  BrManageMenuButton,
  BrPageContext,
} from "@bloomreach/react-sdk";

interface MenuModels {
  menu: Reference;
}

export default function MenuComponent() {
  const component = React.useContext(BrComponentContext);
  const page = React.useContext(BrPageContext);
  const menuRef = component?.getModels<MenuModels>().menu;
  const menu = menuRef && page?.getContent<Menu>(menuRef);

  if (!menu) {
    return null;
  }

  return (
    <ul className={page?.isPreview() ? "has-edit-button" : ""}>
      {/* ... */}

      <BrManageMenuButton menu={menu} />
    </ul>
  );
}

Manage content button can be placed inside a component using BrManageContentButton component with non-empty content property.

import React from "react";
import { Document, Reference } from "@bloomreach/spa-sdk";
import { BrManageContentButton, BrProps } from "@bloomreach/react-sdk";

interface BannerModels {
  document: Reference;
}

export default function Banner({ component, page }: BrProps) {
  const { document: documentRef } = component.getModels<BannerModels>();
  const document = documentRef && page.getContent<Document>(documentRef);

  return (
    <div className={page.isPreview() ? "has-edit-button" : ""}>
      {/* ... */}

      <BrManageContentButton
        content={document}
        documentTemplateQuery="new-banner-document"
        folderTemplateQuery="new-banner-folder"
        parameter="document"
        root="banners"
        relative
      />
    </div>
  );
}

Add new content button can be placed inside a component using BrManageContentButton directive but without passing a content entity.

import React from "react";
import { BrManageContentButton, BrProps } from "@bloomreach/react-sdk";

export default function News({ component, page }: BrProps) {
  // ...

  return (
    <div className={page.isPreview() ? "has-edit-button" : ""}>
      {/* ... */}

      <BrManageContentButton
        documentTemplateQuery="new-news-document"
        folderTemplateQuery="new-news-folder"
        root="news"
      />
    </div>
  );
}

React Native

The SDK is fully compatible with React Native framework, but there are some of the best practices.

It is impossible to use <div> elements in React Native, and it is recommended to use the hst.nomarkup container type in the backend configuration.

If there is a need to support other container types, those types should be overridden explicitly in the mapping. The default implementation is using HTML entities as described in the documentation.

import React from "react";
import { View } from "react-native";
import { TYPE_CONTAINER_BOX } from "@bloomreach/spa-sdk";

function MyBoxContainer() {
  return (
    <View>
      {React.Children.map(props.children, (child) => (
        <View>{child}</View>
      ))}
    </View>
  );
}

export default function App() {
  return <BrPage mapping={{ [TYPE_CONTAINER_BOX]: MyBoxContainer }} />;
}

The fallback mapping should be overridden to prevent errors on production when a new component type pops up on the backend since the default implementation is returning a plain text node.

import React from "react";
import { Text } from "react-native";
import { TYPE_CONTAINER_ITEM_UNDEFINED } from "@bloomreach/spa-sdk";

function Fallback({ component, page }) {
  return (
    page.isPreview() && (
      <Text>Component "{component.getType()}" is not defined.</Text>
    )
  );
}

export default function App() {
  return <BrPage mapping={{ [TYPE_CONTAINER_ITEM_UNDEFINED]: Fallback }} />;
}

For integration with the Relevance Module, the visitor identifier storing and passing should be handled on the application side. There is the visitor option in the configuration that enables a setup without using cookies.

import React, { useEffect, useMemo, useRef } from "react";
import { read, write } from "./storage";

export default function App() {
  const ref = useRef(null);
  const configuration = {
    /* ... */
    visitor: read("visitor"),
  };

  const visitor =
    ref.current &&
    ref.current.state.page &&
    ref.current.state.page.getVisitor();

  useEffect(() => void visitor && write("visitor", visitor), [
    visitor && visitor.id,
  ]);

  return <BrPage ref={ref} configuration={configuration} />;
}

Reference

The React SDK is using Bloomreach SPA SDK to interact with Bloomreach Content.

BrPage

This is the entry point to the page model. This component requests and initializes the page model, and then renders the page root component with React children passed to this component. The component also sets the page object into BrPageContext.

Property	Required	Description
`configuration`	yes	The configuration of the SPA SDK.
`mapping`	yes	The brXM and React components mapping.
`page`	no	Preinitialized page instance or prefetched page model. Mostly that should be used to transfer state from the server-side to the client-side.

BrComponent

This component points to where children or some component should be placed. BrComponent can be used inside BrPage or mapped components only. If React children are passed, then they will be rendered as-are. Otherwise, it will try to render all children components recursively.

Property	Required	Description
`path`	no	The path to a component. The path is defined as a slash-separated components name chain relative to the current component (e.g. `main/container`). If it is omitted, all the children will be rendered.

BrManageContentButton

This component places a button on the page that opens the linked content in the document editor or opens a document editor to create a new one. The button will only be shown in preview mode.

Property	Required	Description
`content`	no	The content entity to open for editing.
`documentTemplateQuery`	no	Template query to use for creating new documents. For Content SaaS, the key is like `new-banner-document` for `banner` document type. In case the document type is in a namespace other than `brxsaas`, the key also includes namespace prefix, such as `new-vuestorefront-accordion-document` for `accordion` document type in `vuestorefront` namespace.
`folderTemplateQuery`	no	Template query to use in case folders specified by `path` do not yet exist and must be created. For Content SaaS, the key is like `new-banner-folder` for `banner` document type. In case the document type is in a namespace other than `brxsaas`, the key also includes namespace prefix, such as `new-vuestorefront-accordion-folder` for `accordion` document type in `vuestorefront` namespace.
`path`	no	Initial location of a new document, relative to the `root`.
`parameter`	no	Name of the component parameter in which the document path is stored.
`pickerConfiguration`	no	The root path of the CMS configuration to use for the picker, relative to `/hippo:configuration/hippo:frontend/cms`.
`pickerEnableUpload`	no	When this picker is used for images, this flag determines if uploads are enabled.
`pickerInitialPath`	no	The initial path to use in the picker if nothing has been selected yet, relative to the pickerRootPath.
`pickerRemembersLastVisited`	no	Whether the picker remembers the last visited path.
`pickerRootPath`	no	The absolute root path to use in the picker, or an empty string if the channel content path is used.
`pickerSelectableNodeTypes`	no	Types of nodes to be able to select in the picker, separated by a comma.
`relative`	no	Flag indicating that the picked value should be stored as a relative path.
`root`	no	Path to the root folder of selectable document locations.

BrManageMenuButton

This component places a button on the page that opens the linked menu in the menu editor. The button will only be shown in preview mode.

Property	Required	Description
`menu`	yes	The related menu model.

BrComponentContext

The React Context holding the current brXM Component.

BrPageContext

The React Context holding the current brXM Page.
