API reference

Find public import paths, application factory APIs, and compatible dependency versions.

Effront separates application APIs from host adapters and build integrations. Use @effront/core to define pages, routes, services, and Server Functions. Choose the other packages for hosting, Markdown, or styling.

Runtime imports from @effront/core require the react-server condition. Keep them in the application graph configured by effront(), not in a host process with react-server enabled globally. For application setup, see Getting started and Platforms.

Application factory index

Application.effront<Services>() returns these factories and methods. Related definitions must share one factory instance or a derivative from withMiddleware.

Member	Result	Reference
`Component`, `Page`, `Layout`, `Loading`	Rendered content and route UI definitions	Components
`Routes`, `Middleware`	Route groups and scoped request middleware	Routes and Middleware
`ServerFn`	Schema-validated Server Functions	ServerFn
`withMiddleware`	Derived factories with additional middleware and the same application identity	Application
`make`	An application definition, not a running server	Application

Dependency matrix

Package or package family	Version
All Effront packages	`0.2.0`
`react`, `react-dom`	`19.3.0`
`@vitejs/plugin-rsc`	`0.5.35`
`effect`, `@effect/platform-browser`, host-specific Effect packages	`4.0.0-rc.116`
`alchemy`	`2.0.0-beta.79`
`@comark/react`	`0.6.2`

Keep Effront package versions aligned, including optional adapters and integrations. React and React DOM must match, and @vitejs/plugin-rsc@0.5.35 includes the matching 19.3.0 RSC transport. ViewTransition and addTransitionType are stable React 19.3.0 APIs. Keep Effect family versions aligned as well. Vite integrations declare a public Vite peer dependency of *. The setup guides use VitePlus.
