Bloomreach SPA SDK

NPM License

Bloomreach SPA SDK provides simplified headless integration with Bloomreach Experience Manager for JavaScript-based applications. This library interacts with the Page Model API and exposes a simplified and framework-agnostic interface over the page model.

What is Bloomreach Experience Manager?

Bloomreach Experience Manager (brXM) is an open and flexible CMS designed for developers and marketers. As the original headless CMS, brXM allows developers to build quickly and integrate with the systems. While it’s built for speed, it also provides top-notch personalization and channel management capabilities for marketers to drive results.

Features

  • Page Model API client;
  • Page Model parser;
  • URL generator;
  • brXM integration.

Get Started

Installation

To get the SDK into your project with NPM:

npm install @bloomreach/spa-sdk

And with Yarn:

yarn add @bloomreach/spa-sdk

Usage

The following code snippet requests a related page model and shows the page's title.

import axios from 'axios';
import { initialize } from '@bloomreach/spa-sdk';
 
async function showPage(path) {
  const page = await initialize({
    httpClient: axios,
    options: {
      live: {
        cmsBaseUrl: 'http://localhost:8080/site',
        spaBaseUrl: '',
      },
      preview: {
        cmsBaseUrl: 'http://localhost:8080/site/_cmsinternal',
        spaBaseUrl: '/site/_cmsinternal?bloomreach-preview=true',
      },
    },
    request: { path },
  });
 
  document.querySelector('#title').innerText = page.getTitle();
}
 
showPage(`${window.location.pathname}${window.location.search}`);

Configuration

The initialize function supports several options you may use to customize page initialization.

Option Required Default Description
httpClient yes none The HTTP client that will be used to fetch the page model. Signature is similar to Axios client.
options yes none The CMS URL options.
options.live yes none The CMS URL options for the live site.
options.live.apiBaseUrl no options.live.cmsBaseUrl + "/resourceapi" Base URL of the Page Model API for the live site (e.g. http://localhost:8080/site/resourceapi or http://localhost:8080/site/channel/resourceapi).
options.live.cmsBaseUrl yes none Base URL of the live site (e.g. http://localhost:8080/site or http://localhost:8080/site/channel).
options.live.spaBaseUrl no "" Base URL of the live SPA (e.g. /account or //www.example.com).
options.preview yes none The CMS URL options for the preview site.
options.preview.apiBaseUrl no options.preview.cmsBaseUrl + "/resourceapi" Base URL of the Page Model API for the preview site (e.g. http://localhost:8080/site/_cmsinternal/resourceapi or http://localhost:8080/site/_cmsinternal/channel/resourceapi).
options.preview.cmsBaseUrl yes none Base URL of the live site (e.g. http://localhost:8080/site/_cmsinternal or http://localhost:8080/site/_cmsinternal/channel).
options.preview.spaBaseUrl no "" Base URL of the live SPA (e.g. /site/_cmsinternal?bloomreach-preview=true or /site/_cmsinternal/channel?bloomreach-preview=true). This path and query string parameters will be used to detect whether it is a preview mode or not.
request yes none Current user's request.
request.path yes none The path part of the URL, including a query string if present (e.g. /path/to/page?foo=1).
request.headers no {} An object holding request headers. It should contain a Cookie header if rendering is happening on the server-side.
visitor no none An object holding information about the current visitor.
visitor.id yes none The current visitor identifier.
visitor.header yes none An HTTP-header using to pass the visitor identifier to the Page Model API.
window no window A window object reference will be used to interact with brXM. It needs to be set when initialize is being called within an iframe or worker process.

Functions

Function Description
initialize(config, model?): Promise<Page> This function accepts a configuration object as an argument and returns a promisified JavaScript object representing the page model. In case, when the page model has already been fetched, you can pass this JSON blob as a second parameter.
destroy(page: Page): void Destroys the integration with the SPA page object.
isPage(value): boolean Checks whether a value is a page.
isComponent(value): boolean Checks whether a value is a page component.
isContainer(value): boolean Checks whether a value is a page container.
isContainerItem(value): boolean Checks whether a value is a page container item.
isMeta(value): boolean Checks whether a value is a meta-data object.
isMetaComment(value): boolean Checks whether a value is a meta-data comment.
isLink(value): boolean Checks whether a value is a link.
isReference(value): boolean Checks whether a value is a content reference.

Constants

Constant Description
META_POSITION_BEGIN Meta-data following before a page component.
META_POSITION_END Meta-data following after a page component.
TYPE_CONTAINER_BOX A blocked container with blocked items.
TYPE_CONTAINER_INLINE A blocked container with inline items.
TYPE_CONTAINER_NO_MARKUP A container without surrounding markup.
TYPE_CONTAINER_ORDERED_LIST An ordered list container.
TYPE_CONTAINER_UNORDERED_LIST An unordered list container.
TYPE_LINK_EXTERNAL Link to a page outside the current application.
TYPE_LINK_INTERNAL Link to a page inside the current application.
TYPE_LINK_RESOURCE Link to a CMS resource.

Objects

Page

The Page class represents the brXM page to render. This is the main entry point to the page model.

Method Description
getComponent(...componentNames): Component | undefined Gets a component in the page (e.g. getComponent('main', 'right')). If componentNames is omitted, then the page root component will be returned.
getContent(reference: Reference | string): Content | undefined Gets a content item used on the page.
getMeta(meta): Meta[] Generates a meta-data from the provided meta model.
getTitle(): string | undefined Gets the title of the page, or undefined if not configured.
getUrl(link?: Link): string Generates a URL for a link object.
- If the link object type is internal, then it will prepend spaBaseUrl. In case when the link starts with the same path as in cmsBaseUrl, this part will be removed.
- If the link parameter is omitted, then the link to the current page will be returned.
- In other cases, the link will be returned as-is.
getUrl(path: string): string Generates an SPA URL for the path.
- If it is a relative path, then it will prepend spaBaseUrl.
- If it is an absolute path, then the behavior will be similar to internal link generation.
getVisitor(): Visitor | undefined Gets the current visitor information, or undefined if the Relevance Module is not enabled. The Visitor object consists of the following properties:
- id: string - the current visitor identifier;
- header: string - an HTTP-header using to pass the visitor identifier to the Page Model API.
getVisit(): Visit | undefined Gets the current visit information, or undefined if the Relevance Module is not enabled. The Visit object consists of the following properties:
- id: string - the current visit identifier;
- new: boolean - a flag showing that this is a new visit.
isPreview(): boolean Returns whether the page is in the preview mode.
rewriteLinks(content: string, type?: string): string Rewrite links to pages and resources in the HTML content. This method looks up for a tags with data-type and href attributes and img tags with src attribute. Links will be updated according to the configuration used to initialize the page. The type parameter is similar to mimeType parameter of the DOMParser.
sync(): void Synchronizes the brXM integration state (UI elements positions).
toJSON(): object A plain JavaScript object of the page model.
Component

The Component class corresponds to page nodes, and it may hold other components inside.

Method Description
getId(): string Returns the component id.
getMeta(): Meta[] Returns the component meta-data collection.
getModels(): object Returns the map of the component models.
getUrl(): string | undefined Returns the link to the partial component model.
getName(): string Returns the name of the component.
getParameters(): object Returns the parameters of the component.
getChildren(): Component[] Returns the direct children of the component.
getComponent(...componentNames: string[]): Component | undefined Looks up for a nested component.
getComponentById(id: string): Component | undefined Looks up for a nested component by its id.
Container

The Container class represents a page node that is actually present in the DOM but as an element surrounding its children. Container extends the Component class, and therefore, all the Component methods are applicable here.

Method Description
getType(): string | undefined Returns the type of a container.
Container Item

The ContainerItem objects are usually visible on the page and interact with the user. Container Item extends the Component class, and therefore, all the Component methods are applicable here.

Method Description
getType(): string | undefined Returns the type of a container item. The available types depend on which container items have been configured in the backend (e.g. "Banner").
isHidden(): boolean Returns whether the component should not render anything. Hiding components is only possible with the Relevance feature.
on(eventName: string, listener: Function): Function Subscribes for an event and returns the unsubscribe function.
off(eventName: string, listener: Function): void Unsubscribes from an event.
Content

The Content object holds document data that is used by the page components.

Method Description
getId(): string Returns the content id.
getLocale(): string | undefined Returns the content locale.
getMeta(): Meta[] Returns the content meta-data collection.
getName(): string Returns the content name.
getData(): object Returns the content data as it is returned in the Page Model API.
getUrl(): string | undefined Returns the link to the content.
Meta

The Meta objects are being used by the brXM to page and its components.

Method Description
getData(): string Returns the meta-data.
getPosition(): string Returns the meta-data position relative to the related element.
