Marko + Express

Quick Start

npm init marko -- --template vite-express

See the the express sample project for a working example.

From Scratch

First install Marko and the express related dependencies:

npm install marko @marko/express express --save

Skip the view engine

The built in view engine for express may be asynchronous, but it doesn't support streaming (check out Rediscovering Progressive HTML Rendering to see why this is so important). So instead we'll bypass the view engine and use @marko/express.


The @marko/express adds a res.marko method to the express response object. This function works much like res.render, but doesn't impose the restrictions of the express view engine and allows you to take full advantage of Marko's streaming and modular approach to templates.

By using res.marko you'll automatically have access to req, res, app, app.locals, and res.locals from within your Marko template and custom tags. These values are added to

import express from "express";
import markoPlugin from "@marko/express";
import Template from "./template.marko";

const app = express();

app.use(markoPlugin()); //enable res.marko(template, data)

app.get("/", function (req, res) {
  res.marko(Template, {
    name: "Frank",
    count: 30,
    colors: ["red", "green", "blue"]


BYOB (Bring your own bundler)

For the large portion of Marko's API a bundler is required. The example code above assumes that Marko templates can be loaded in your environment. Marko supports a number of bundlers, take a look through our supported bundlers and pick what works best for you.
