Marko + Vite


npm install @marko/vite vite

Example config

import { defineConfig } from "vite";
import marko from "@marko/vite";
export default defineConfig({
  plugins: [marko()],

Linked Mode

By default this plugin operates in linked mode (you can disabled this by passing linked: false as an option). In linked mode the plugin automatically discovers all of the entry .marko files while compiling the server, and tells Vite which modules to load in the browser.

With this you do not create .html files for Vite, it's Marko all the way down! Scripts, styles and other content that would have been injected into the .html files is instead automatically injected into your .marko templates.

In this mode you must use the Vite SSR API.

Here's an example using express.

import { createServer } from "vite";

const app = express();
let loadTemplate;

if (process.env.NODE_ENV === "production") {
  // Use Vite's built asset in prod mode.
  loadTemplate = () => import("./dist");
} else {
  // Hookup the vite dev server.
  const vite = await createServer({
    server: { middlewareMode: true }

  loadTemplate = () => vite.ssrLoadModule("./template.marko");

app.get("/", async (req, res) => {
  const template = (await loadTemplate()).default;
  // When the template is loaded, it will automatically have `vite` assets inlined.
  template.render({ hello: "world" }, res);


For a more real world setup check out our vite express example app.



You can manually override Marko's Babel configuration by passing a babelConfig object to the @marko/vite plugin. By default Babel's regular config file resolution will be used.

  babelConfig: {
    presets: ["@babel/preset-env"],


In some cases you may want to embed multiple isolated copies of Marko on the page. Since Marko relies on some window properties to initialize this can cause issues. For example, by default Marko will read the server rendered hydration code from window.$components. In Marko you can change these window properties by rendering with { $global: { runtimeId: "MY_MARKO_RUNTIME_ID" } } as input on the server side.

This plugin exposes a runtimeId option produces output that automatically sets $global.runtimeId on the server side and initializes properly in the browser.

marko({ runtimeId: "MY_MARKO_RUNTIME_ID" });


Set this to false to opt out of linked mode. When this is false, the plugin will only handle resolving and transforming .marko files.
