Hummersmyth

Hummersmyth is a tiny and simple yet powerful HTML renderer and DOM creator for Node.js and the browser. Hummersmyth has no dependencies.

Getting started

Node.js

Install hummersmyth using npm.

npm install hummersmyth --save

Then require it into any module.

const Hummersmyth = require('hummersmyth');

Browser

Hummersmyth has no dependencies, which makes it easy to include in a browser.

You can download the latest release from the repository

hummersmyth.js unminified, including comments
hummersmyth.min.js minified version

Use a script tag to directly add Hummersmyth to the global scope.

<script src="hummersmyth.min.js"></script>

Usage

const 
  ul = Hummersmyth.ul,
  li = Hummersmyth.li,  
  p = Hummersmyth.p,
  input = Hummersmyth.input,
  div = Hummersmyth.div;

// Render HTML snippet. Attributes are specified as plain JSON objects.
// Each tag function supports a variable list of arguments. 
// Attributes descriptors should be passed before 'content' for better readability,
// but can also be mixed with element content.

var html = 
  ul({ id: 'the-list', class: "list" },
    li({ class: 'first-item'}, "First item"),
    li("Second item"),
    li("Third item")
  );

// -> html === <ul id="the-list" class="list"><li class="first-item">First item</li><li>Second item</li><li>Third item</li></ul>'

html = 
  p(
    input({ id: 'uid', type: 'text', value: "abc123" }),

    // Multiple attributes descriptors will be merged.
    input({ type: 'password' }, { id: 'pw' }, { class: 'password' })
  );

// -> html === <p><input id="uid" type="text" value="abc123"><input type="password" id="pw" class="password"></p>


// Attributes descriptors and element content can also be given as an array.
html = 
  div(
    [ 
      { id: "i1" }, 
      p("abc"), 
      { class: 'xyz' } 
    ]
  );

// -> html === <div id="i1" class="xyz"><p>abc</p></div>

Examples

Render complete HTML page

const 
  html = Hummersmyth.html,
  head = Hummersmyth.head,
  meta = Hummersmyth.meta,
  title = Hummersmyth.title,
  link = Hummersmyth.link,
  body = Hummersmyth.body,
  div = Hummersmyth.div,
  script = Hummersmyth.script;

var page = 
  html(
    head(
      meta({ charset: 'utf-8' }),
      meta({ 
        'http-equiv': 'X-UA-Compatible', 
        content: 'IE=edge'
      }),
      meta({
        name: 'viewport',
        content: 'width=device-width, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0'
      }),	
      title("My page"),
      link({ 
        href: 'https://fonts.googleapis.com/css?family="Source+Sans+Pro"', 
        rel: 'stylesheet' 
      })
    ),
    body(
      div({ id: 'main' }),
      script({ 
        src: 'https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js', 
        language: 'javascript', 
        type: 'text/javascript' 
      }),
      script({ 
        src: '/static/index.js', 
        language: 'javascript', 
        type: 'text/javascript' 
      })
    )
  );

Dynamically update DOM

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Hummersmyth example</title>
</head>
<body>
    <script src="hummersmyth.min.js"></script>
    <script>
      document.addEventListener('DOMContentLoaded', function()
      {
        // div is just a shortcut ...
        const div = Hummersmyth.div;

        var snippet = div({ id: 'main' }, "Blah");

        // Hummersmyth exports 2 methods to add html snippets to an existing DOM element.
        // - appendTo(element, html)
        // - prependTo(element, html)
        Hummersmyth.appendTo(document.body, snippet);
      });
    </script>
</body>
</html>

Dynamically update DOM using jQuery

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Hummersmyth example</title>
</head>
<body>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
    <script src="hummersmyth.min.js"></script>
    <script>
        $(document).ready(function()
        {
          // div is just a shortcut ...
          const div = Hummersmyth.div;

          var snippet = div({ id: 'main' }, "Blah");

          $('body').append(snippet);
        });
    </script>
</body>
</html>
