Semitexa SSR - Twig-based server rendering with components, layouts, assets, and deferred slots

README 文档

README

Twig-based server-side rendering with components, layout slots, theme overrides, and locale-aware URL generation.

Purpose

Renders HTML responses using Twig. Provides a component system discovered via #[AsComponent], layout slot composition via #[AsLayoutSlot], theme override support for module templates, and locale-aware URL generation.

Role in Semitexa

Depends on Twig, Locale, and Tenancy. Used by Mail, Platform WM, Platform User, Platform Settings, and Demo. Required for packages that render HTML pages.

Key Features

#[AsComponent] attribute for component discovery
#[AsLayoutSlot] for layout slot registration
#[AsDataProvider] and #[AsTwigExtension] for template extensions
LayoutRenderer for slot-based page composition
Theme override system (module templates overridable via src/theme/)
UrlGenerator with locale-aware routing
ModuleTemplateRegistry for per-module template discovery
Development hot-reload support
Automatic robots.txt fallback with Semitexa-specific crawler hints when the project does not provide a real file
Automatic llms.txt fallback for LLM-oriented crawl guidance when the project does not provide a real file

Deferred SSE Safety

SSR_DEFERRED_PERSISTENT_SSE=false is the safe default. Deferred SSR streams final HTML blocks once and then closes the SSE connection.
SSR_DEFERRED_PERSISTENT_SSE_REQUIRE_AUTH=true adds a second guard for persistent mode. Even when persistent SSE is explicitly enabled, live reconnect-capable streams still require an authenticated session by default.
For public pages and demos, keep persistent SSE disabled unless you have a specific live-update use case and have capacity controls in place.

Notes

SSR is required for HTML pages. JSON-only APIs do not need this package. Layout slots use handle-based scoping: * for global, layout frame name, or specific page handle.

If a project does not provide robots.txt or public/robots.txt, SSR emits a minimal default file automatically. Set ROBOTS_SITEMAP_URL when you want the generated file to advertise a classic sitemap explicitly. SSR also exposes /sitemap.json as a crawler-oriented JSON route inventory and advertises it from the fallback robots.txt.

If a project does not provide llms.txt or public/llms.txt, SSR emits a fallback /llms.txt document that points agents to /sitemap.json, /robots.txt, and Semitexa's page-document JSON conventions.

When an SSR page route declares extra response formats via #[AsPayload(produces: ...)], Semitexa renders <link rel="alternate" type="..."> tags for the non-HTML variants of the current payload DTO. This keeps the <head> aligned with the actual route contract instead of hardcoding alternates in Twig.

semitexa/ssr 适用场景与选型建议

semitexa/ssr 是一款基于 PHP 开发的 Composer 扩展包，目前已累计 128 次下载、GitHub Stars 达 1，最近一次更新时间为 2026 年 02 月 23 日，在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向：「twig」「components」「Rendering」「layouts」「frontend」「deferred」等业务场景。在实际项目中，围绕这些方向常见需要落地的问题包括：接口对接、性能调优、并发安全、与既有框架（Laravel / ThinkPHP / Yii / Webman 等）的兼容适配，以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 semitexa/ssr 或与其功能相近的方案，如果你在选型或落地过程中遇到问题，例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查，欢迎联系我们协助评估。
