# WRNexusJS 0.7.0 — 21-Point Security and Performance Implementation WRNexusJS 0.7.0 implements the framework-side foundations for all 21 requested security and performance areas. Secure defaults, compiler diagnostics, runtime enforcement, production reports, release gates, and adapter interfaces are included in this source release. External infrastructure remains an application/deployment responsibility: TLS termination, Redis or another distributed cache, antivirus/CDR engines, image transcoding services, CDN configuration, an OTLP/metrics backend, database indexes, registry MFA, and project-specific authorization policy. ## Implementation matrix | # | Area | Implemented in 0.7.0 | | --: | -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | 1 | Targets and budgets | Expanded route, CSS, HTML, image, hydration, SSR, Web Vitals, request-count, and long-task budgets with warning/error enforcement and build reporting. | | 2 | Compiler/template security | Context-aware URL validation, unsafe protocol diagnostics, dangerous DOM/dynamic-code diagnostics, client/server boundary checks, persisted-secret checks, Trusted HTML policy, and bounded secure hydration serialization. | | 3 | Browser headers | CSP with nonce/report-only support, Trusted Types, HSTS, COOP, CORP, Referrer-Policy, Permissions-Policy, nosniff, frame protection, Origin-Agent-Cluster, and presets. | | 4 | Sessions/authentication | Idle and absolute expiry, sliding access, secure cookie defaults, server-side session backend support, and safer session lifecycle configuration. | | 5 | CSRF/CORS/authorization | CSRF token plus Origin and Fetch Metadata validation, opt-in exact-origin CORS, and continued server-side authz/tenant policy enforcement. | | 6 | Gateway/API hardening | URL/header/query/body limits, timeouts, concurrency limits, host/proxy trust, request IDs, IP rate limits, Fetch Metadata, access logs, and WebSocket queue/origin/message controls. | | 7 | SSRF | Safe fetch validates protocols and hosts, resolves and checks addresses, blocks private/special networks, revalidates redirects, limits size/time/redirects, and avoids credential forwarding. | | 8 | Uploads | Extension/MIME/size/aggregate/path controls, generated names, secure download disposition, inspector hooks, and antivirus/CDR adapter interfaces. | | 9 | Database | Query timing, timeouts, row caps, slow-query reporting, duplicate/N+1 detection, SELECT-star/unbounded-query warnings, and per-request query records. | | 10 | SSR/server | Runtime route classification, zero-JS/prerender analysis, request dedupe and cache foundations, streaming compatibility, and build-report visibility. | | 11 | Hydration/CSR | Static pages default to zero framework JavaScript, auto/client/document navigation modes, partial/lazy hydration foundations, batched reactive work, keyed updates, cancellation/disposal, and hydration telemetry. | | 12 | Build/bundles | Server/client separation, minification/hashing support, immutable runtime assets, runtime classification, production build reports, and enforceable budgets. | | 13 | CSS | Existing minification/token tooling plus diagnostics for transition-all, expensive blur/shadow patterns, broad selectors, and duplicate keyframes. | | 14 | Images/icons/fonts | Responsive image planning, srcset/sizes/dimensions/loading/decoding/fetch-priority policy, remote-host validation, LCP/oversizing audits, and continued per-icon/font optimization helpers. | | 15 | HTTP delivery | Brotli-first negotiation, gzip fallback, compression exclusions, ETags/conditional responses, immutable assets, cache-control helpers, stale policies, and preload/modulepreload support. | | 16 | Realtime/WebSocket | Authentication, origins, message byte/rate/depth limits, room/user quotas, schema and authorization predicates, prototype-pollution rejection, and gateway backpressure controls. | | 17 | Observability | Counters, gauges, histograms, HTTP middleware, request/error/active-request metrics, same-origin Web Vitals, browser collector, exporters, and Server-Timing integration. | | 18 | DevToolbar | Security checks for forms/CSRF/CSP/mixed content/storage/hydration leaks and performance checks for transfer, DOM, hydration, images, blocking assets, and long tasks. | | 19 | Tests/release gates | 0.7 validator, production security audit, benchmark budgets, type/lint/test/format pipeline, deterministic UI references, stage integrity checks, and compatibility validation. | | 20 | Supply chain | Private release policy, aligned versions, explicit migration, deterministic CycloneDX SBOM, secret/source-map/source leakage scanning, package SHA-256 manifests, and clean/pushed Git requirements. | | 21 | New packages | `@wrnexus/security`, `@wrnexus/cache`, `@wrnexus/image`, `@wrnexus/observability`, and `@wrnexus/benchmark`. | ## Compatibility - Existing 0.6 component, parser, store, RPC, and runtime contracts remain supported. - The updater preserves existing security, performance, observability, and navigation configuration. - New projects use `navigation.mode: "auto"`; fully static routes ship no WRNexusJS JavaScript. - Set `navigation.mode: "client"` only when every route requires in-place client navigation. ## Mandatory project review before production Framework controls do not replace application-specific review. Each production project must define and test: - Roles, permissions, object ownership, tenant boundaries, and sensitive field access. - CSP source allowlists and third-party scripts. - Trusted proxies, public hosts, CORS origins, WebSocket origins, and outbound URL allowlists. - Session duration, MFA/passkey requirements, recovery policy, and high-risk reauthentication. - Upload type policy, storage isolation, antivirus/CDR adapters, quotas, and retention. - Cache privacy and invalidation for authenticated or tenant-specific data. - Database indexes, pool sizes, query limits, backups, and migration rollback. - Observability retention, sampling, redaction, and incident alerts. - CDN/TLS configuration, registry MFA, short-lived publish credentials, and disaster recovery. ## Production gates ```sh bun install bun run validate:0.7 bun run security:framework bun run sbom bun run benchmark:framework bun run validate:staging bun run check bun run release:prepare ``` Run `release:private` only after generated files and release changes are committed, pushed, and the working tree is clean.
