-Shown in order of execution: - -## astro:before-preparation - -A signal dispatched by the Astro View Transitions router at the start of a page navigation. It runs before any new page content is loaded, allowing you to perform actions like displaying a loading spinner, preventing the navigation (e.g., for unsaved form changes), or overriding default behavior with the loader() function, which allows you to manually set the `event.newDocument` property. Correlates to the `navigation` native event. - -## astro:after-preparation - -Dispatched on the `window.document` after Astro has finished preparing and linking the new page's content but before the content is swapped into the document. For most purposes, the native event you would use to react after the page content is loaded is the DOMContentLoaded event. However, when using Astro's View Transitions, the DOMContentLoaded event is not triggered during client-side navigation. - -## astro:before-swap - -A lifecycle event in Astro's View Transitions router that fires right before the new page content is swapped into the DOM. It allows you to run code just before the visual transition happens, giving you a chance to customize the swap or modify the new document before it's displayed. This event is particularly useful for setting up page-specific styles or animations on the new content. It is the last chance for developers to interact with a page navigation just before the new content is swapped into the DOM. - -## astro:after-swap - -A lifecycle event in the Astro framework that is dispatched after the contents of a page have been replaced during a client-side navigation, but before the view transition is complete. This event is part of Astro's View Transitions API, which provides a single-page application (SPA)-like feel to multi-page apps (MPAs). Key uses: - -- Re-attaching event listeners: For websites that use JavaScript for interactivity, the event listeners on the old page are lost when the DOM is replaced. The astro:after-swap event allows you to re-attach these listeners to the elements on the newly swapped-in page. -- Managing state across transitions: It can be used to persist settings like dark mode across page navigation. You can set up a function to run on this event that checks a user's theme preference and applies the correct theme to the new page. -- Integrating with other libraries: Libraries like HTMX, which rely on the DOM to be processed, can be re-initialized using this event to ensure they continue to function correctly after a navigation. - -## astro:page-load - -A custom event dispatched by Astro's View Transitions router. It serves a similar purpose to the browser's native DOMContentLoaded event but is specifically designed to handle script execution and state re-initialization during client-side navigation facilitated by View Transitions. It is specifically designed to re-run client-side scripts after navigation within a Single-Page App (SPA)-like experience, which is enabled by Astro's View Transitions. In a standard Astro application (Multi-Page App), client-side JavaScript only runs once on the initial page load. This event is an alternative to DOMContentLoaded for use with View Transitions. - -## delayed - -This is a virtual event that waits for the first user interaction or five seconds to pass. It is intended for scripts that result in a layout shift and should be delayed in execution so as not to affect LCF layout in Lightouse. - -## visible - -This is a virtual event that triggers when an element scrolls into or near the viewport, using the Intersection Observer API. It fires when the target element is 500px below the viewport (before it becomes visible to the user), allowing for preloading or lazy initialization of components. - -**Configuration:** - -- **Root:** `document.body` - Observes relative to the document body -- **Root Margin:** `0px 0px 500px 0px` - Triggers 500px before element enters viewport -- **Threshold:** `0.01` - Triggers when 1% of element is visible -- **Delay:** `100ms` - Throttles observer callbacks to once per 100ms - -**Usage:** - -Scripts using the 'visible' event type must either: - -1. Provide a `targetSelector` property pointing to the element(s) to observe -2. Or ensure elements in the DOM have a `data-script` attribute matching the script name - -This event is ideal for: - -- Lazy loading social media embeds (fetch oEmbed data before visible) -- Deferring heavy component initialization -- Preloading content just before user sees it -- Optimizing initial page load performance - -**Browser Support:** Requires IntersectionObserver API (95%+ browsers, IE11 needs polyfill) - -## consent-gated - -This is a virtual event for scripts that require user consent before execution, primarily for GDPR compliance. Scripts using this event type will check the user's cookie consent preferences before loading. - -**Current Implementation:** Temporarily behaves as `astro:page-load` event. Full consent checking logic is planned for future implementation. - -**Configuration:** - -Scripts using the 'consent-gated' event type must provide a `meta` object with: - -- **consentCategory** (required): One of `'necessary'`, `'analytics'`, `'advertising'`, or `'functional'` - -**Usage Example:** - -```typescript -import { LoadableScript, type TriggerEvent } from '@components/Scripts/loader' - -class AnalyticsScript extends LoadableScript { - static override scriptName = 'Analytics' - static override eventType: TriggerEvent = 'consent-gated' - static override meta = { - consentCategory: 'analytics' - } - - static override init(): void { - // Initialize analytics only if user has consented - } -} -``` - -**Use Cases:** - -- Analytics and tracking scripts (Google Analytics, Plausible, etc.) -- Advertising and marketing pixels (Google Ads, Facebook Pixel, etc.) -- Third-party embeds that collect user data -- Error monitoring with PII collection (Sentry with Session Replay) -- Any script that processes personal data under GDPR diff --git a/src/components/scripts/loader/__tests__/loader.spec.ts b/src/components/scripts/loader/__tests__/loader.spec.ts deleted file mode 100644 index 2960b3e69..000000000 --- a/src/components/scripts/loader/__tests__/loader.spec.ts +++ /dev/null @@ -1,578 +0,0 @@ -/** -

Content can be deleted or renamed. Always dynamically fetch the first available item from listing pages (articles, services, case-studies, etc.) and navigate to it. This prevents test breakage when content changes. - **Playwright E2E Tests**: ALWAYS run with `DEBUG=1` environment variable (e.g., `DEBUG=1 npx playwright test`). This prevents the Playwright test runner from launching its own dev server. The user maintains a running dev server for development. - **NEVER run the full e2e test suite** unless explicitly requested by the user. The full suite is very resource intensive and takes over 10 minutes to run. Only run specific e2e test files when verification is needed (e.g., `DEBUG=1 npx playwright test test/e2e/specific-file.spec.ts`). diff --git
