A measured pass rather than a bulk rewrite. Numbers come from the source and from a browser. The migration entry covers what has accumulated since 0.8.5 and would otherwise reach upgraders unannounced: the Tabs output contract, the Sidebar BEM rename, the layout components leaving Tailwind so their rendered class lists changed, LayoutSplitter and CustomScrollbar changing props and outputs, the ui.css families that were removed, and the theme tokens that now paint where they previously resolved to nothing. The audit records what is still wrong, with counts: 32 outputs across 16 components that nothing emits, 23 components still on the scaffold pattern, 66 without a local style block and therefore dependent on ui.css, and 10 still using Tailwind. A test pins the dead-output count at 32 as a ceiling that only moves down, so rebuilding a component tightens it and no new one can be added quietly. It also records what is not worth doing. Splitting the runtime saves 3 to 4 kB gzipped on a first visit to a file cached for a year, and hydration costs 1.5 ms for 21 scopes across 4325 elements, so neither is a real problem.

WRNexusJS
WRNexusJS is a compiler-driven, SSR-first, Bun-native full-stack framework for building secure, fast, maintainable applications with .wrn pages, layouts, components, stores, server functions, client functions, typed outputs, APIs, validation, authentication, realtime rooms, and production tooling.
Current framework version: 0.8.0
Core principles
- Secure by default with CSP, CSRF, safe serialization, URL policies, request limits, SSRF protection, secret scanning, and release gates.
- Performance-first SSR with zero framework JavaScript for static pages and selective hydration for interactive pages.
- One compiler-understood
.wrnmodel for markup, props, state, outputs, and runtime-specific functions. - Backward-compatible package upgrades with migrations, generated references, validation scripts, and private publishing controls.
- Package kits that give developers public helpers, package tests, documentation, and complete UI blocks where a package has a developer-facing interface.
Quick start
bun install
bun run validate:0.8
bun run check
bun run dev
Create or upgrade a project:
bunx @wrnexus/cli@0.8.0 create my-app
bunx @wrnexus/cli@0.8.0 update --version=0.8.0 --report
Package kits in 0.8
All 39 framework packages expose a documented helper/API surface and package tests. UI-facing packages additionally own complete .wrn blocks composed from @wrnexus/ui:
@wrnexus/auth— complete account, sign-in, sign-up, MFA, passkey, recovery, device, provider, and security blocks.@wrnexus/captcha— challenge, field, status, extraction, verification, response, and context helpers.@wrnexus/i18n— recursive locale loading, fallback chains, request resolution, SSR/browser translations, language controls, and formatters.@wrnexus/image— responsive picture plans, secure loaders, placeholders, preload hints, audits, and image blocks.@wrnexus/realtime— typed messages, room connections, presence, typing, metadata, composer, status, and message blocks.@wrnexus/uploader— upload attributes, result validation, formatting, dropzone, and status blocks.@wrnexus/validation— parse/throw helpers, consistent error responses, summaries, and field errors.@wrnexus/ui— the complete shared design-system component catalog.
Infrastructure packages remain helper/API-only so database, encryption, security, compiler, server, and build packages do not pull browser UI into production server code.
Security note for encrypted HTTP bodies
@wrnexus/encryption supports authenticated application-layer request and response envelopes with method, path, request-ID, timestamp, expiry, key-rotation, body-size, and replay binding.
This feature does not replace HTTPS. It is appropriate for service-to-service calls, native/mobile clients, controlled agents, or selected fields with server-managed keys. It cannot hide data from an end user when a browser receives the decryption key.
