description: >-
  Client-side and embeddable surfaces Adobe ships for Experience Cloud, as distinct from
  the server-side SDKs in packages/. Three families: the Edge Network collectors that run
  in the browser and render personalization (Web SDK, Client Data Layer), the AEM
  headless/SPA client libraries that render Adobe-managed content inside a customer app,
  and the Spectrum design-system component libraries (web components and React) that make
  a customer UI look like an Adobe product.

families:
  - family: Edge Network / personalization runtime
    description: >-
      Browser libraries that send events to the Adobe Experience Platform Edge Network and
      render Target / Offer Decisioning personalization in the page. This is where
      Experience Cloud actually touches an end user's browser.
    components:
      - name: Adobe Experience Platform Web SDK
        package: '@adobe/alloy'
        registry: npm
        version: 2.35.0
        published: '2026-07-30'

          jsdelivr_api: https://data.jsdelivr.com/v1/packages/npm/@adobe/alloy
          note: >-
            Distributed both as an npm package and as a CDN build. Adobe's own
            documentation ships a base-code snippet that loads alloy.js from the customer's
            own hosted copy or from the Adobe Experience Platform Tags (Launch) library, so
            the deployed version depends on the customer's tag property rather than on a
            pinned URL.
        supersedes:
          - at.js (Adobe Target)
          - AppMeasurement.js (Adobe Analytics)

        repository: https://github.com/adobe/adobe-client-data-layer
        official: true
        description: Event-driven client data layer used by AEM Core Components and read by
          the Web SDK / Tags.
  - family: AEM headless + SPA rendering
    description: Client libraries that fetch Adobe Experience Manager content into a
      customer-built front end.
    components:
      - name: AEM Headless Client (JS)
        package: '@adobe/aem-headless-client-js'
        registry: npm
        version: 4.0.0
        published: '2024-07-11'

        official: true
        description: Client for AEM GraphQL persisted queries and content fragment delivery.
        currency_note: Last release 2024-07-11 — nearly two years stale against a
          continuously-released AEM Cloud Service.
      - name: AEM SPA Component Mapping
        package: '@adobe/aem-spa-component-mapping'
        registry: npm
        version: 1.1.1
        published: '2021-04-15'
        repository: https://github.com/adobe/aem-spa-component-mapping
        official: true
        description: Maps SPA front-end components to AEM resource types for the SPA Editor.
        currency_note: Last release 2021-04-15. Recorded as published-but-dormant.
  - family: Spectrum design system
    description: >-
      Adobe's design system, shipped as framework-agnostic web components and as React
      components. Not an API client — included because it is the embeddable UI layer Adobe
      publishes for building surfaces that sit inside Experience Cloud (App Builder
      extensions, custom admin UIs).
    components:
      - name: Spectrum Web Components
        package: '@spectrum-web-components/*'
        example_package: '@spectrum-web-components/button'
        registry: npm
        version: 1.12.2
        published: '2026-07-06'
        repository: https://github.com/adobe/spectrum-web-components
        official: true
        kind: web-components
      - name: React Spectrum
        package: '@adobe/react-spectrum'
        registry: npm
        version: 3.47.3
        published: '2026-07-31'
        repository: https://github.com/adobe/react-spectrum
        official: true
        kind: react-components
hosted_surfaces:
  - name: Adobe Experience Platform Tags (formerly Launch)
    description: >-
      Adobe-hosted tag management. The Web SDK is most commonly deployed as a Tags
      extension rather than as a direct script include, which means the version running on
      a customer's site is set in the Tags property, not pinned in the page.
    note: Recorded as a distribution mechanism, not a component library.
