Every public export of @lazarv/react-server, grouped by subpath. Signatures, JSDoc descriptions, and examples are generated directly from the runtime's TypeScript definitions — what you read here mirrors what your editor shows on hover.
Within each page, symbols are sorted alphabetically inside their group (Functions, Constants, Classes, Interfaces, Types). Overloaded functions collapse into a single entry with all signatures listed.
Runtime
<dl> <dt>[Core](/api/core) · `@lazarv/react-server`</dt> <dd>The core runtime entry point. HTTP context hooks, cookie helpers, caching utilities, and rendering controls.</dd> <dt>[Client](/api/client) · `@lazarv/react-server/client`</dt> <dd>Client and outlet contexts for navigation, refresh, and prefetching, plus the `ClientOnly` component for post-hydration code.</dd> <dt>[Router](/api/router) · `@lazarv/react-server/router`</dt> <dd>Typed routing primitives for the file-system and programmatic routers — route factories, schema validators, and param extractors.</dd> <dt>[Navigation](/api/navigation) · `@lazarv/react-server/navigation`</dt> <dd>`<Link>`, `<Form>`, `<Refresh>`, `<ReactServerComponent>`, navigation hooks and guards, redirect helpers, and scroll restoration.</dd> </dl>Data, rendering, resiliency
<dl> <dt>[Resources](/api/resources) · `@lazarv/react-server/resources`</dt> <dd>`createResource` and `createResources` — typed server resources binding validated data loaders to routes.</dd> <dt>[Remote Components](/api/remote) · `@lazarv/react-server/remote`</dt> <dd>Load a remote React component from another `@lazarv/react-server` deployment and render it server-side.</dd> <dt>[Error Boundary](/api/error-boundary) · `@lazarv/react-server/error-boundary`</dt> <dd>Error boundaries for server components — catch rendering errors, render fallbacks, surface info to observability.</dd> <dt>[Prerender](/api/prerender) · `@lazarv/react-server/prerender`</dt> <dd>Partial pre-rendering controls: `usePrerender` to mark a component for build-time rendering and the `withPrerender` HOC.</dd> </dl>Caching
<dl> <dt>[Memory Cache](/api/memory-cache) · `@lazarv/react-server/memory-cache`</dt> <dd>Default in-memory cache provider. `useCache`, `invalidate`, and client-side cache helpers.</dd> <dt>[Storage Cache](/api/storage-cache) · `@lazarv/react-server/storage-cache`</dt> <dd>Durable cache backend on [unstorage](https://unstorage.unjs.io/) — Redis, Cloudflare KV, Upstash, filesystem, and more.</dd> <dt>[RSC](/api/rsc) · `@lazarv/react-server/rsc`</dt> <dd>Low-level RSC serialization helpers — serialize and deserialize React server component payloads directly.</dd> </dl>Advanced
<dl> <dt>[Worker](/api/worker) · `@lazarv/react-server/worker`</dt> <dd>Helpers for modules with the `"use worker"` directive — Node Worker Threads on the server, Web Workers on the client.</dd> <dt>[MCP](/api/mcp) · `@lazarv/react-server/mcp`</dt> <dd>Model Context Protocol primitives — typed tools, resources, and prompts exposed via an MCP server handler.</dd> <dt>[HTTP](/api/http) · `@lazarv/react-server/http`</dt> <dd>Low-level HTTP context types shared across middleware, route handlers, and server functions.</dd> </dl>Config, build, deploy
<dl> <dt>[Config](/api/config) · `@lazarv/react-server/config`</dt> <dd>Configuration schema and helpers — `ReactServerConfig` for typed `react-server.config.mjs` and `generateJsonSchema`.</dd> <dt>[Adapters](/api/adapters) · `@lazarv/react-server/adapters/*`</dt> <dd>Shared types and helpers for deploy adapters. The same surface is re-exported from every target.</dd> <dt>[Node](/api/node) · `@lazarv/react-server/node`</dt> <dd>Mount the runtime inside an existing Node.js server — Express, Fastify, NestJS, raw `http`. Used in middleware mode.</dd> <dt>[Dev](/api/dev) · `@lazarv/react-server/dev`</dt> <dd>Programmatic entry point to the development server. Equivalent to running `react-server` without arguments.</dd> <dt>[Build](/api/build) · `@lazarv/react-server/build`</dt> <dd>Programmatic build entry point — useful for custom build pipelines. Equivalent to `react-server build`.</dd> </dl>Observability & tooling
<dl> <dt>[DevTools](/api/devtools) · `@lazarv/react-server/devtools`</dt> <dd>Configuration surface for the in-browser DevTools panel.</dd> <dt>[Telemetry](/api/telemetry) · `@lazarv/react-server/telemetry`</dt> <dd>OpenTelemetry integration. Safe no-op when OpenTelemetry packages are not installed — import directly without guarding.</dd> </dl>All content on these pages is auto-generated from the TypeScript definitions in packages/react-server/**/*.d.ts.
