+description: Vite library mode and SSR configuration
+---
+
+# Build and SSR
+
+## Library Mode
+
+Build a library for distribution:
+
+```ts
+// vite.config.ts
+import { resolve } from 'node:path'
+import { defineConfig } from 'vite'
+
+export default defineConfig({
+  build: {
+    lib: {
+      entry: resolve(import.meta.dirname, 'lib/main.ts'),
+      name: 'MyLib',
+      fileName: 'my-lib',
+    },
+    rolldownOptions: {
+      external: ['vue', 'react'],
+      output: {
+        globals: {
+          vue: 'Vue',
+          react: 'React',
+        },
+      },
+    },
+  },
+})
+```
+
+### Multiple Entries
+
+```ts
+build: {
+  lib: {
+    entry: {
+      'my-lib': resolve(import.meta.dirname, 'lib/main.ts'),
+      secondary: resolve(import.meta.dirname, 'lib/secondary.ts'),
+    },
+    name: 'MyLib',
+  },
+}
+```
+
+### Output Formats
+
+- Single entry: `es` and `umd`
+- Multiple entries: `es` and `cjs`
+
+### Package.json Setup
+
+```json
+{
+  "name": "my-lib",
+  "type": "module",
+  "files": ["dist"],
+  "main": "./dist/my-lib.umd.cjs",
+  "module": "./dist/my-lib.js",
+  "exports": {
+    ".": {
+      "import": "./dist/my-lib.js",
+      "require": "./dist/my-lib.umd.cjs"
+    },
+    "./style.css": "./dist/my-lib.css"
+  }
+}
+```
+
+## Multi-Page App
+
+```ts
+export default defineConfig({
+  build: {
+    rolldownOptions: {
+      input: {
+        main: resolve(import.meta.dirname, 'index.html'),
+        nested: resolve(import.meta.dirname, 'nested/index.html'),
+      },
+    },
+  },
+})
+```
+
+## SSR Development
+
+### Middleware Mode
+
+Use Vite as middleware in a custom server:
+
+```ts
+import express from 'express'
+import { createServer as createViteServer } from 'vite'
+
+const app = express()
+
+const vite = await createViteServer({
+  server: { middlewareMode: true },
+  appType: 'custom',
+})
+
+app.use(vite.middlewares)
+
+app.use('*all', async (req, res, next) => {
+  const url = req.originalUrl
+
+  // 1. Read and transform index.html
+  let template = await fs.readFile('index.html', 'utf-8')
+  template = await vite.transformIndexHtml(url, template)
+
+  // 2. Load server entry
+  const { render } = await vite.ssrLoadModule('/src/entry-server.ts')
+
+  // 3. Render app
+  const appHtml = await render(url)
+
+  // 4. Inject into template
+  const html = template.replace('<!--ssr-outlet-->', appHtml)
+
+  res.status(200).set({ 'Content-Type': 'text/html' }).end(html)
+})
+
+app.listen(5173)
+```
+
+### SSR Build
+
+```json
+{
+  "scripts": {
+    "build:client": "vite build --outDir dist/client",
+    "build:server": "vite build --outDir dist/server --ssr src/entry-server.ts"
+  }
+}
+```
+
+The `--ssr` flag:
+- Externalizes dependencies by default
+- Outputs for Node.js consumption
+
+### SSR Manifest
+
+Generate asset mapping for preload hints:
+
+```bash
+vite build --outDir dist/client --ssrManifest
+```
+
+Creates `dist/client/.vite/ssr-manifest.json` mapping module IDs to chunks.
+
+### SSR Externals
+
+Control which deps get bundled vs externalized:
+
+```ts
+export default defineConfig({
+  ssr: {
+    noExternal: ['some-package'],  // Bundle this dep
+    external: ['another-package'], // Externalize this dep
+  },
+})
+```
+
+### Conditional Logic
+
+```ts
+if (import.meta.env.SSR) {
+  // Server-only code (tree-shaken from client)
+}
+```
+
+## JavaScript API
+
+### createServer
+
+```ts
+import { createServer } from 'vite'
+
+const server = await createServer({
+  configFile: false,
+  root: import.meta.dirname,
+  server: { port: 1337 },
+})
+
+await server.listen()
+server.printUrls()
+```
+
+### build
+
+```ts
+import { build } from 'vite'
+
+await build({
+  root: './project',
+  build: { outDir: 'dist' },
+})
+```
+
+### preview
+
+```ts
+import { preview } from 'vite'
+
+const previewServer = await preview({
+  preview: { port: 8080, open: true },
+})
+previewServer.printUrls()
+```
+
+### resolveConfig
+
+```ts
+import { resolveConfig } from 'vite'
+
+const config = await resolveConfig({}, 'build')
+```
+
+### loadEnv
+
+```ts
+import { loadEnv } from 'vite'
+
+const env = loadEnv('development', process.cwd(), '')
+// Loads all env vars (empty prefix = no filtering)
+```
