hydraline_server 0.0.4

Hydraline pure-Dart server: shelf/Dart Frog SSR, single-pass streaming, HTMX helpers, caching and bot-aware delivery with a byte-identical document body.

0.0.4

• HEAD requests now return the response headers with an empty body instead of a full rendered body.
• DocumentBuilder receives the matched RouteEntry as its data argument, so builders can read route metadata and the concrete path without re-parsing.
• InMemoryCache gained an optional maxEntryBytes cap: oversized pages are not stored, bounding worst-case memory.
• HTMX helpers (HtmxResponse, Htmx.redirect) reject header values containing CR/LF (response-splitting defense).
• Assets.injectFlutterAssets escapes baseHref before embedding it in the injected <script> tags.
• Redirect handling unified through Http.redirect/Http.gone; cached-response headers emitted lowercase for HTTP/2 friendliness.

0.0.3

• Fixed: route patterns with a trailing slash in the manifest (e.g. /about/) now match, because route paths are canonicalised during matching.
• Http.redirect preserves an explicit status (301/302/303/307/308) instead of coercing everything non-301 to 302.
• app routes now emit nofollow from route metadata (previously only noindex was honoured on app routes).
• The cache key canonicalises query-parameter order, so ?a=1&b=2 and ?b=2&a=1 share one cache entry.
• The ETag hash applies an explicit 64-bit mask, making it independent of the platform's int-overflow behaviour.
• Removed a dead delivery parameter from the cached-response path.
• Added issue_tracker to the package metadata.

0.0.2

• Fixed: builders registered under dynamic route patterns (/product/:id) are now invoked for matching concrete paths; previously dynamic routes silently rendered empty pages.
• Fixed: the HTML cache key now includes the query string; /page?a=1 and /page?a=2 no longer share one entry.
• Request paths are canonicalised (duplicate/trailing slashes) before route matching and cache lookup.
• ETag upgraded to 64-bit FNV-1a; If-None-Match handles ETag lists, weak validators (W/) and * per RFC 9110.
• Cacheable responses carry Vary: Accept-Encoding.
• Breaking: HydralineCache.set lost its unused etag parameter.
• X-Robots-Tag header name is emitted lowercase consistently.

0.0.1

Initial release.

• hydralineMiddleware - shelf middleware: route matching against the RouteManifest, SSR for document/hybrid routes via pure-Dart DocumentBuilders, pass-through for app routes.
• UA-blind builder contract - DocumentBuilder(Request, Object?) cannot see the User-Agent; cloaking is prevented architecturally.
• Bot-aware transport - buffered (Content-Length) for bots, chunked streaming for users; byte-identical bodies.
• Automatic X-Robots-Tag - emitted for noindex/nofollow routes and for app routes (which default to noindex).
• RedirectException - 301/302/custom statuses and .gone() for 410 from inside builders.
• HydralineCache - pluggable cache with HydralineCache.inMemory() (max-size eviction, TTL); middleware integration with ETag, If-None-Match → 304 and Cache-Control.
• Htmx helpers - renderFragment, response (with HX-Trigger map), trigger, redirect (HX-Redirect), plus HtmxResponse with retarget/reswap headers.
• Assets.serveCoreAssets - robots.txt, sitemap.xml and the first-party L0-L1 JS bundles (vanilla-islands.js, htmx-glue.js).
• Assets.injectFlutterAssets - Flutter script injection for island routes.
• Http - status helpers, path canonicalization, withRobots.
• DartFrogAdapter - Dart Frog integration.
