shave-template

A no curly-brackets {} template module for populating HTML templates with dynamic data and building dynamic lists and tables.

(Intended for client-side use. For a similar server-side library see templateking.)

Content insertion is accomplished by targeting standard HTML tag names and other CSS selectors. Works with virtual-dom. (For a similar non-virtual-dom library see curly-free-template.)

This module allows you to develop plain HTML/CSS templates with dummy data in the places dynamic data will be inserted. The benefit is that the templates can be developed independently from the programming that dynamically incorporates data into the web page.

You can also use this module to build dynamic lists and tables. Use a selector to identify a portion of the provided template, such as a list item or a table row, and this module will use it as a sub-template to be duplicated and populated with dynamic data for each member of a given array.

It also provides for layering templates. A page template can be wrapped by a sub-section template, those together can be wrapped by a section template, and those by a site template. The number of nested template layers is unlimited.

Once the templates are compiled, this module applies an object you've provided that identifies CSS selectors as key names paired with values, and replaces (or appends/prepends) the default content of the elements in the templates that are identified by the corresponding CSS selectors with the provided values.

Input templates values may be type string or virtual-dom object.

This module returns a virtual-dom object useful for DOM-diffing.

example

var fs = require('fs')
var main = require('main-loop')
var shaved = require('shave-template')

var button = fs.readFileSync('public/button.html', 'utf-8')

var loop = main({ n: 0 }, render, require('virtual-dom'))
document.querySelector('#content').appendChild(loop.target)

function render (state) {
  return shaved(button, {
    '#count': state.n,
    'button': {onclick: onclick}
  })
  function onclick () {
    loop.update({ n: state.n + 1 })
  }
}

button.html

    <h1>clicked <span id="count">0</span> times</h1>
    <button>click me!</button>

index.html

<!doctype html>
<html>
  <body>
    <div id="content"></div>
    <script src="bundle.js"></script>
  </body>
</html>

Execute npm run build or browserify -t brfs examples/index.js > examples/public/bundle.js to compile the example code, then load the index.html file in a browser.

layering templates and map example

var outer = fs.readFileSync('public/outer.html', 'utf-8')
var section = fs.readFileSync('public/section.html', 'utf-8')
var template = fs.readFileSync('public/template.html', 'utf-8')

var vdom = shaved([outer, section, template], {
  '#sectionheader': 'Start Here:',
  'div#message': {class: 'myclass', '_html': 'Clicker ready.'},
  '#clicks': 'Clicks: ' + state.n,
  '#mapme': {_map: {'li': ['one', 'two', 'three', 'four']}},
  'button': {onclick: onclick, '_html': 'click here'}
})

outer.html

<!DOCTYPE html>
<html>
  <head>
    <title>shave-template</title>
    <link rel="stylesheet" type="text/css" href="public/css/main.css">
  </head>
  <body>
    <div class="template">template</div>
    <div id="scripts">
      <script src="public/js/main.js"></script>
    </div>
  </body>
</html>

section.html

      <h2 id="sectionheader">section header</h2>
      <div class="template"></div>

template.html

        <div><div id="message">message goes here</div>
        <div id="clicks" style="color: red;">clicks go here</div>
        <ul id="mapme">
          <li>a</li>
          <li>b</li>
          <li>c</li>
        </ul>
        <button>button here</button></div>

...outputs a virtual-dom that renders to:

<!DOCTYPE html>
<html>
  <head>
    <title>shave-template</title>
    <link rel="stylesheet" type="text/css" href="public/css/main.css">
  </head>
  <body>
  </head>
  <body>
    <div class="template">
      <h2 id="sectionheader">Start Here:</h2>
      <div class="template">
        <div><div id="message" class="myclass">Clicker ready.</div>
        <div id="clicks" style="color: red;">Clicks: 1</div>
        <ul id="mapme">
          <li>one</li>
          <li>two</li>
          <li>three</li>
          <li>four</li>
        </ul>
        <button>click here</button></div>
      </div>
    </div>
    <div id="scripts">
      <script src="public/js/main.js"></script>
    </div>
  </body>
</html>

(onclick function is assigned to button onclick handler, not shown. Layout reformatted for clarity.)

TIP: The link stylesheet element can be _mapappend'ed to dynamically add more stylesheets, and the script element can be _mapappend'ed (or _mapprepend'ed if order of scripts is a factor) to add more scripts.
