MobileBridgeNext safe area insets now inject styles via Constructable Stylesheets instead of a style element.

  • MobileBridgeNext now injects safe area inset styles using the Constructable Stylesheets API and document.adoptedStyleSheets instead of appending a style element to document.head.
  • Safe area inset style injection now includes feature detection and exits gracefully if CSSStyleSheet or adoptedStyleSheets APIs are unavailable.
  • The function for intercepting native browser APIs was renamed from restoreProperty to interceptProperty, affecting the fetch, print, share, window.open, and history modules.

Navigation handler sets navigationVersion 2 on the shopify global and adds a history.pushState fallback for unresolved link navigations.

  • The navigation system now sets Symbol.for('navigationVersion') to 2 on the global shopify object at initialization, advertising the active navigation protocol version.
  • When home-link click simulation cannot process a URL, a new fallback uses history.pushState and dispatches a popstate event to complete the navigation instead of calling the App Bridge navigate API.
  • When navigating via a home link, the target URL is now derived from the home link element's href attribute rather than the original destination URL.

The title-bar module adds groupType support to secondary action button groups.

  • The title-bar module now accepts a groupType property on secondary action button groups.
  • groupType is destructured from button group objects alongside label, icon, disabled, and buttons fields.
  • When groupType is provided on a button group, it is forwarded to the title bar protocol.

Navigation utilities updated to support s-app-nav elements and fix home link detection via getAttribute fallback.

  • The qt selector function now includes s-app-nav as a navigation container, matching ui-nav-menu support for click interception.
  • App Bridge will now intercept and handle client-side navigation for clickable elements inside s-app-nav components.
  • Home link detection in the navigation handler now uses getAttribute('rel') as a fallback when the rel property is nullish, fixing routing for custom elements.

Added idToken timeout and error hardening, sidekick conversation stream events, and title bar button pressed state.

  • The id-token module now enforces a 60-second timeout when requesting session tokens from the host, rejecting with a clear error if the host does not respond in time.
  • The id-token module now validates that retrieved tokens are non-empty strings, throwing an idToken unavailable error for missing or invalid tokens.
  • The fetch module now handles idToken failures gracefully, logging an error and skipping the Authorization header instead of propagating the exception.

The fetch interceptor removes extensionOriginFetch support, simplifying all intercepted requests to use native fetch.

  • The fetch module removes the extensionOriginFetch code path, which previously allowed extension-origin requests to be routed through a custom fetch implementation from internalApiPromise.
  • Helper utilities for serializing Request objects to plain objects and reconstructing Responses from ArrayBuffers were removed from the utilities module alongside extensionOriginFetch.
  • The session token retry logic in the fetch interceptor is simplified, with both the initial request and the auth-header retry now always using native self.fetch directly.

Intents module gains a reactive request signal and response now only exists when an intent is active.

  • The intents module now exposes api.intents.request as a reactive signal that tracks the current active intent value.
  • The api.intents.response property is now a getter returning undefined when no intent is active, instead of always being defined.
  • Intent request state is kept synchronized with the internal API via subscription and unsubscribed automatically on page unload.

Internal refactoring of private field utilities with a minor defensive hasOwnProperty improvement.

  • The private field access guard in _utilities.js was updated to use {}.hasOwnProperty.call instead of Object.prototype.hasOwnProperty.call, making it more resilient to prototype pollution.
  • Internal private field helpers were renamed and reorganized in _utilities.js: the counter variable and key-creation and field-check functions swapped names.
  • _bootstrap.js was updated to call the renamed private field helpers privateKeyCounter and checkPrivateField consistently.

Several modules broadened protocol support from Shopify-only to all protocols, with minor error tracking improvements.

  • toast.show and toast.hide switched from SHOPIFY_PROTOCOLS to ALL_PROTOCOLS, enabling them to work across all protocol environments.
  • sidekick.registerToolHandler and sidekick.registerContextCallback switched from SHOPIFY_PROTOCOLS to ALL_PROTOCOLS.
  • tools.register, tools.unregister, and tools.clear switched from SHOPIFY_PROTOCOLS to ALL_PROTOCOLS.

Added mobile safe area inset support via a CSS custom property when the MobileBridgeNext flag is enabled.

  • Bootstrap now injects a --shopify-safe-area-inset-bottom CSS custom property initialized to 0px when the MobileBridgeNext feature flag is active.
  • The safe area inset bottom value is automatically subscribed to from the host and kept in sync as a CSS variable on the root element.
  • A body::after pseudo-element is added to reserve physical space at the bottom of the page equal to the safe area inset height.

The fetch module gained extensionOriginFetch support, and several modules narrowed their protocol scope to Shopify-only contexts.

  • The fetch module now supports an extensionOriginFetch handler that routes requests through a custom fetch implementation when available, affecting both initial and retry-on-session requests.
  • The toast module's show and hide methods now only activate in Shopify protocol contexts, replacing the previous all-protocols behavior.
  • The tools module's register, unregister, and clear methods now scope exclusively to Shopify protocols.

This build introduces first-class support for app intents — apps can now read structured intent data from the URL, respond to intents with ok/error/closed outcomes, and detect intent context via `environment.intent`. Two new modules (`analytics` and `tools`) were added, and the title bar gains support for `<s-button-group>` elements.

  • Two new modules registered: `analytics.js` and `tools.js`
  • `intents` module: new `api.data.intent` property that parses and exposes structured intent payload (`type`, `action`, `data`) from the URL's `intent` query parameter
  • `intents` module: new `api.intents.response` object with `ok()`, `error()`, and `closed()` methods for sending a response back to the intent caller (only exposed when an intent is present)

  • Captured 34 feature modules including navigation, fetch, save-bar, toast, resource-picker, and POS
  • Identified 4 infrastructure files: bootstrap, utilities, remote-ui (RPC), and web-vitals
  • Bundle size: 88.5 KB minified, expanding to ~167 KB deminified across 38 files
