vite.config.ts

vite.config.ts is the configuration entrypoint for a SolidStart v2 application. It replaces v1's app.config.ts.

import { nitro } from "nitro/vite";
import { defineConfig } from "vite";
import { solidStart } from "@solidjs/start/config";

export default defineConfig({
  plugins: [solidStart(), nitro()],
});

Responsibilities

• Pass application, routing, middleware, environment, and serialization settings to solidStart().
• Add ordinary Vite plugins and options at the Vite config level.
• Pass server, deployment, prerendering, task, and WebSocket settings through the top-level nitro property.

import { nitro } from "nitro/vite";
import { defineConfig } from "vite";
import { solidStart } from "@solidjs/start/config";

export default defineConfig({
  plugins: [
    solidStart({
      middleware: "./src/middleware/index.ts",
      serialization: { mode: "json" },
    }),
    nitro(),
  ],
  nitro: {
    preset: "node_server",
    prerender: {
      routes: ["/"],
    },
  },
});

SolidStart v2 requires Vite 8 or 9. The default scripts are vite dev and vite build; vite preview locally serves a completed production build.

For the available server options and deployment presets, see the Nitro configuration reference.
