A minimalist template engine for DOM generation and manipulation, working for both client-side and server-side rendering
Mini-Van is an ultra-lightweight template engine for DOM composition and manipulation. With only 0.7kB in the minified bundle size (0.5kB gzipped), Mini-Van enables you to build comprehensive UI with elegant and expressive vanilla JavaScript code:
// Reusable components can be just pure vanilla JavaScript functions.
// Here we capitalize the first letter to follow React conventions.
const Hello = () => div(
p("👋Hello"),
ul(
li("🗺️World"),
li(a({href: "https://vanjs.org/"}, "🍦VanJS")),
),
)
van.add(document.body, Hello())
// Alternatively, you can write:
// document.body.appendChild(Hello())
You can convert any HTML snippet into Mini-Van code with our online converter.
Mini-Van is the slimmed-down version of VanJS, which aims to provide an ultra-lightweight, zero-dependency, and unopinionated Reactive UI framework based on pure vanilla JavaScript and DOM. Compared to VanJS, Mini-Van further reduces the gzipped minified bundle size to 0.5kB and (more importantly) can be used on the server-side as a template engine.
Mini-Van can be used on the server side as a template engine to render dynamic web content for HTTP servers. An NPM package was published here: www.npmjs.com/package/mini-van-plate. Thus it can be used in Node.js or Bun.
There are 2 modes for server-side integration: van-plate mode (based on text templating, thus doesn't need the DOM dependency), and mini-van mode (based on DOM, thus needs the DOM dependency).
npm install mini-van-plate
van-plate modeIn van-plate mode, HTML content is generated purely through text templating. It can be easily integrated with your HTTP server to render dynamic web content. See the sample code below:
import http from "node:http"
import van from "mini-van-plate/van-plate"
const {a, body, li, p, ul} = van.tags
const hostname = '127.0.0.1'
const port = 8080
console.log("Testing DOM rendering...")
// Expecting `<a href="https://vanjs.org/">🍦VanJS</a>` printed in the console
console.log(a({href: "https://vanjs.org/"}, "🍦VanJS").render())
const server = http.createServer((req, res) => {
res.statusCode = 200
res.setHeader('Content-Type', 'text/html; charset=utf-8')
res.end(van.html(
body(
p("Your user-agent is: ", req.headers["user-agent"] ?? "Unknown"),
p("👋Hello"),
ul(
li("🗺️World"),
li(a({href: "https://vanjs.org/"}, "🍦VanJS")),
),
),
))
})
server.listen(port, hostname, () =>
console.log(`Server running at http://${hostname}:${port}/`))

As illustrated in the example, render method can be called on the object returned from the tag function to generate a string that can be used for serving.
van.html is a helper function defined in van-plate.js that is equivalent to:
(...args) => "<!DOCTYPE html>" + tags.html(...args).render()
mini-van modeThe behavior in mini-van mode is similar to the behavior in browser context. i.e.: DOM objects will be created by tag functions. As Node.js doesn't have the built-in support for DOM objects, you need to provide a 3rd-party Document object before integrating with Mini-Van in this mode.
There are multiple 3rd-party options for the Document object. In the example below, we will demonstrate the integration with the help of jsdom.
Note that, mini-van mode doesn't work in Bun yet due to the integration issue with jsdom.
First, install jsdom:
npm install jsdom
Sample code:
import http from "node:http"
import jsdom from "jsdom"
import van from "mini-van-plate"
const dom = new jsdom.JSDOM("")
const {html, tags} = van.vanWithDoc(dom.window.document)
const {a, body, li, p, ul} = tags
const hostname = '127.0.0.1'
const port = 8080
console.log("Testing DOM rendering...")
const anchorDom = a({href: "https://vanjs.org/"}, "🍦VanJS")
// anchorDom is an HTMLAnchorElement
// Expecting `<a href="https://vanjs.org/">🍦VanJS</a>` printed in the console
console.log(anchorDom.outerHTML)
const server = http.createServer((req, res) => {
res.statusCode = 200
res.setHeader('Content-Type', 'text/html; charset=utf-8')
res.end(html(
body(
p("Your user-agent is: ", req.headers["user-agent"] ?? "Unknown"),
p("👋Hello"),
ul(
li("🗺️World"),
li(a({href: "https://vanjs.org/"}, "🍦VanJS")),
),
),
))
})
server.listen(port, hostname, () =>
console.log(`Server running at http://${hostname}:${port}/`))

Similar to van-plate mode, we have a helper function html defined in mini-van.js which is equivalent to:
(...args) => "<!DOCTYPE html>" + tags.html(...args).outerHTML
Similarly, Mini-Van can work with Deno as well, in both van-plate mode and mini-van mode. A Deno module was published here: deno.land/x/minivan.
van-plate modeSample code:
Requires Deno 1.35 or later.
import van from "https://deno.land/x/minivan@0.6.0/src/van-plate.js"
const {a, body, li, p, ul} = van.tags
const port = 8080
console.log("Testing DOM rendering...")
// Expecting `<a href="https://vanjs.org/">🍦VanJS</a>` printed in the console
console.log(a({href: "https://vanjs.org/"}, "🍦VanJS").render())
console.log(`HTTP webserver running. Access it at: http://localhost:${port}/`)
Deno.serve({port}, req => new Response(
van.html(
body(
p("Your user-agent is: ", req.headers.get("user-agent") ?? "Unknown"),
p("👋Hello"),
ul(
li("🗺️World"),
li(a({href: "https://vanjs.org/"}, "🍦VanJS")),
),
),
),
{
status: 200,
headers: {"content-type": "text/html; charset=utf-8"},
},
))

mini-van modeLikewise, mini-van mode needs a 3rd-party DOM library to provide the Document object. We will show an example with the integration of deno-dom.
Sample code:
Requires Deno 1.35 or later.
import { DOMParser } from "https://deno.land/x/deno_dom@v0.1.38/deno-dom-wasm.ts"
import van from "https://deno.land/x/minivan@0.6.0/src/mini-van.js"
const document = new DOMParser().parseFromString("", "text/html")!
const {tags, html} = van.vanWithDoc(document)
const {a, body, li, p, ul} = tags
const port = 8080
console.log("Testing DOM rendering...")
const anchorDom = a({href: "https://vanjs.org/"}, "🍦VanJS")
// anchorDom is an HTMLAnchorElement
// Expecting `<a href="https://vanjs.org/">🍦VanJS</a>` printed in the console
console.log(anchorDom.outerHTML)
console.log(`HTTP webserver running. Access it at: http://localhost:${port}/`)
Deno.serve({port}, req => new Response(
html(
body(
p("Your user-agent is: ", req.headers.get("user-agent") ?? "Unknown"),
p("👋Hello"),
ul(
li("🗺️World"),
li(a({href: "https://vanjs.org/"}, "🍦VanJS")),
),
),
),
{
status: 200,
headers: {"content-type": "text/html; charset=utf-8"},
},
))

To get started on the client side, add the line below to your script:
import van from "https://cdn.jsdelivr.net/gh/vanjs-org/mini-van/public/mini-van-0.6.0.min.js"
To code without ES6 modules, add the following line to your HTML file instead:
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/vanjs-org/mini-van/public/mini-van-0.6.0.nomodule.min.js"></script>
Alternative, you can download the files (mini-van-0.6.0.min.js, mini-van-0.6.0.nomodule.min.js) and serve them locally.
You can find all relevant Mini-Van files in this Download Table.
Mini-Van exposes the same set of APIs as VanJS for DOM composition and manipulation. Thus for API reference, you can refer to DOM Composition and Manipulation section of VanJS tutorial. Note that: state and state binding are not supported in Mini-Van.
🙏 VanJS aims to build a better world by reducing the entry barrier of UI programming, with no intention or plan on commercialization whatsoever. If you find VanJS interesting, or could be useful for you some day, please consider starring the project. It takes just one seconds but your support means the world to us and helps spread VanJS to a wider audience.
We're looking for the 1.0 milestone (commitment to API stability) soon, your precious feedback will be greatly appreciated. You can submit your feedback by creating issues.
