by mithril

Level: beginner • Mithril.js Version: latest

This example shows a very simple markdown editor using marked.js. Here we can also see how easy it is with Mithril.js to integrate and use 3rd-party libraries. The example was taken from the official website at and slightly modified.

Live Example


Type Name URL


var state = {
	text: "# Markdown Editor\n\nType on the top panel and see the result on the bottom panel",
	update: function(value) {
		state.text = value

var Editor = {
	view: function() {
		return [
			m("textarea.input", {
				oninput: function (e) {
				value: state.text

m.mount(document.body, Editor)


html, body {
    height: 100%;
    margin: 0;

h1, h2, h3, h4, h5, h6, p {
    margin: 0 0 10px;

#editor {
    display: flex;
    height: 100%;

.input, .preview {
    box-sizing: border-box;
    height: 50%;
    margin: 0;
    padding: 10px;
    width: 100%;

.input {
    border: 0;
    border-bottom: 1px solid #ccc;
    outline: none;
    resize: none;

The snippet is using the most current version of Mithril.js framework. It is aimed at beginners and shows some basic recipes.

Besides Mithril.js' hyperscript function m() we can see different Mithril.js API methods like or m.mount.
