🧹 Testing and tooling

• Tests covering tag extraction for all supported JSDoc tags.

@elenajs/plugin-cem-prop@1.0.0

Custom Elements Manifest plugin that creates prop entries from JSDoc annotations.

✨ New features

@elenajs/core@1.0.0

The first stable release of @elenajs/core. 🎉 The API has been validated across 13 release candidates with no breaking changes since rc.1. Everything below is new compared to 0.15.0.

✨ New features

• Two rendering strategies: Patch() updates only the text and attributes that changed. Morph() rebuilds the affected part of the DOM when the template structure changes.
• Shadow DOM support via static shadow = "open" | "closed" and static styles for full style isolation.
• Declarative Shadow DOM support.
• Scoped Custom Element Registries via static registry.
• Composable mixins that work with the Elena() factory function.
• Reactive update cycle with willUpdate(), firstUpdated(), updated() and requestUpdate(). Prop changes are batched via microtasks so multiple synchronous updates result in a single render.
• adoptedCallback() lifecycle hook for responding to document.adoptNode().
• nothing helper for conditional rendering. Renders as an empty string.
• updateComplete promise for waiting until DOM updates finish after prop changes.

🔋Performance

• Patch rendering skips DOM rebuilds entirely when only values change.
• Morph rendering diffs against existing DOM nodes instead of replacing them.
• Lighter HtmlResult template objects reduce memory allocations.
• Changed attributes are updated in place without touching the rest of the DOM.
• Direct prop writes bypass the setter chain during internal updates.
• updateComplete promise is only created when accessed.
• 12% smaller library size through internal refactoring.
• Faster initial render path.

🐞 Bug fixes

• String props recover correctly after being set to an empty string.
• Boolean prop coercion always returns a strict boolean.
• Closed shadow roots are handled correctly.
• Event listeners are re-bound when the inner element is replaced during a morph.
• Whitespace processing matches browser behavior.
• Rendering flag (_isRendering) is more resilient during error recovery.

🧹 Testing and tooling

• 25 test files covering primitives, composites, lifecycle, rendering, render-morph, props, events, shadow DOM, hydration, inheritance, mixins, focus preservation, array rendering, async timing, error recovery, security and SVG/MathML.
• 30+ test fixtures covering all component patterns.
• Visual regression tests via Playwright.
• Performance benchmarks for initial render and re-render.
• Updated TypeScript declarations.
