2.0.0

Version 2.0.0 focuses on simplicity and clear APIs over feature accumulation: fewer abstractions, clearer responsibilities, and a more focused API.

Breaking Changes

Renamed BaseComponent's childConfigs() to registerChildren() and catalogConfig() to createCatalogComponents().
Raised the required Node.js version from >=18 to >=22.
Removed all libraries except Pipes, as they did not fit Nutin's philosophy.
Removed Store. Its responsibilities were unclear and largely duplicated what services already provide.
Removed the force parameter from listenToRenderEvents(). It is no longer needed.

Clarified and separated the responsibilities of the base classes:
- BaseComponent: render lifecycle, hydration, DOM lifecycle, DOM and EventBus subscriptions, teardown, render guard, and composition orchestration.
- Component: props (className, style, data-bindings), configuration/defaults/normalization, and template generation through templateFn.
- View: route parameters, navigation hooks (onEnter() / onExit()), and view identity (viewName).
Components and Views now inherit listen() and listenToRenderEvents() methods with automatic unsubscription.
Added explicit lifecycle hooks:
- Component: onBeforeRender(), onAfterRender(), onBeforeDestroy(), onAfterDestroy()
- View: onEnter(), onExit()
Simplified the EventBus API:
- Added AppEventMap for app-level events. Nutin's internal events are no longer declared in globals.d.ts.
- Event payload types are now objects.
- EventBus now exposes domain facades for Navigation and Lifecycle events.
- Event subscription functions (on*) now return a closure for unsubscription.
- AppEventBus can still be used directly when needed (once(), etc.), but subscriptions must then be unsubscribed manually through the onBeforeDestroy() hook.

// emit
Navigation.navigateTo('path');
// closure
const unsub = Navigation.onNavigate(this.doStuff);
// onDestroy
unsub()

Services now expose a single getInstance() method.
Arguments can be passed to getInstance(), but are only used during the first instantiation.

Added nutin.config.js as the central configuration file for Nutin options, builder, generator, and testing.
Added optional Tailwind CSS v4 support as a utility layer alongside SASS.
Added globally scoped stylesheets co-located with feature files. Use unique class names. Nutin's naming convention encourages prefixes such as home__header.
HTML templates can now be either inline or external .html files. Defining both, or neither, fails the build.
Added configurable Docker ports through nutin.config.js.
Dockerfile now builds a Brotli-enabled image.

Added optional generation of static SEO files from config/seo.json.
- Production builds generate static HTML for each route using the actual components.
- Only title, description, and ogImage remain hand-authored SEO content.
- Generates robots.txt and sitemap.xml.
- Supports per-route disallow and disallowBots.
i18n now uses the URL, aligning with common practices and allowing static SEO HTML to be generated for each language.

Added nutin-update, which updates Nutin to the latest patch or minor version by diffing the project against the new templates and merging compatible changes. Unresolved conflicts are reported.
Added nutin-add docker.
Added GETTING_STARTED.md, providing the architectural context and conventions needed to start working with a Nutin project without immediately consulting the full documentation.
Added AGENTS.md, providing LLMs with the minimal context required to work effectively in a Nutin project.
