# Modulo

Modulo is a lightweight framework for creating **HTML Web Components**: Reusable
snippets of HTML, CSS, and JavaScript that create new HTML-like tags that can
be used and reused anywhere on your site.  Modulo runs entirely in the browser,
and can be incorporated with just a couple lines of code into any HTML file
(see the "Quick start"), such that **no terminal usage is necessary**. However,
if you prefer, you can also start projects using NPM from the Terminal (see the
"NPM start").

- Beginner-friendly features inspired by React, Svelte, and Vue.js, in only
  2000 lines of dependency-free, self-building JavaScript. A “no fuss” drop-in
  for existing web apps or Jamstack static sites.

- Try interactive demos and learn more on the website: <https://modulojs.org/>

Project Status: \`alpha\` *(Well-documented with lots of examples, but still a
work in progress -- help by trying it out!)*

## Quick start


1. Include in any HTML file the single Modulo JavaScript file loaded from a CDN:

\`\`\`html
<script src="https://unpkg.com/mdu.js"></script>
\`\`\`


2. Now define one or more Modulo web components (custom HTML elements).  First,
use \`<template Modulo>\` and \`</template>\` to mark where in your HTML you are
defining our components.  Then, add "Template", "Script", and "Style" tags, to
incorporate HTML, JavaScript, and CSS respectively into your component. E.g.:

\`\`\`html
<template Modulo>
    <Component name="HelloWorld">
        <Template>
            Hello <strong>Modulo</strong> World!
        </Template>
        <Script>
            console.log('Hello Modulo JS world!');
        </Script>
        <Style>
            strong { color: purple; }
        </Style>
    </Component>
</template>
<script src="https://unpkg.com/mdu.js"></script>
\`\`\`

3. Now, you can use and reuse this new custom element wherever you want, just
like any normal HTML tag. E.g.:

\`\`\`html
<x-HelloWorld></x-HelloWorld>
<p>In a P tag: <x-HelloWorld></x-HelloWorld></p>
\`\`\`


* *(Optional)* Download [src/Modulo.js](https://unpkg.com/mdu.js)
  (the single 2000-line file that contains all of the framework) to wherever
  you put JS files for your website (for example, \`/static/js/Modulo.js\`)
