html-maker

Minimalistic HTML builder based on space-pen. Intended to be used from CoffeeScript.

Installation

npm install html-maker --save

Examples:

Here's a CoffeeScript example. The html is generated by a function that is evaluated in the scope of an HtmlMaker instance, so it has access to methods for each HTML element through this:

HtmlMaker = require 'html-maker'
view = ->
  @h1 'Greetings'
  @div class: 'x', =>
    @span class: 'first', 'hi'
    @span class: 'second', 'there!'
  @p 'paragraph'
  @p =>
    @text 'yet'
    @b 'another'
    @text 'paragrah'
html = HtmlMaker.render view

The generated HTML text will be as follows (albeit without the indentation):

<h1>Greetings</h1>
<div class="x">
  <span class="first">hi</span>
  <span class="second">there!</span>
</div>
<p>paragraph</p>
<p>yet<b>another</b>paragrah</p>

Instead of evaluating the html-building closure in the scope of an HtmlMaker (i.e. having the builder in this), the builder can be passed as an argument to the closure by using render_external instead of render:

HtmlMaker = require 'html-maker'
view = (html) ->
  html.h1 'Greetings'
  html.div class: 'x', ->
    html.span class: 'first', 'hi'
    html.span class: 'second', 'there!'
  html.p 'paragraph'
  html.p ->
    html.text 'yet'
    html.b 'another'
    html.text 'paragrah'
html = HtmlMaker.render_external view

This form is more amenable to be used from JavaScript, but still not as nice:

var Maker = require('html-maker');
var view = function(html) {
  html.h1( 'Greetings' );
  html.div({ class: 'x' }, function() {
    html.span({ class: 'first' },  'hi' );
    html.span({ class: 'second' }, 'there!' );
  });
  html.p( 'paragraph' );
  html.p(function() {
    html.text( 'yet' );
    html.b( 'another' );
    html.text( 'paragrah' );
  });
};
var html = Maker.render_external(view);

Partial view helpers

Helper methods that generate partial view can be used with the render method:

form_field = (name) ->
  @p =>
    @text name
    @text ' '
    @input type: 'text', name: name

form = (action, fields) ->
  @form action: action, =>
    for field in fields
      @render form_field, field
    @input type: 'submit', value: 'Submit'

form_html = HtmlMaker.render form, 'send.address.com', ['name', 'address']

Result (indented):

<form action="send.address.com">
  <p>name <input type="text" name="name"></p>
  <p>address <input type="text" name="address"></p>
  <input type="submit" value="Submit">
</form>

If the alternative style using an HtmlMaker argument is desired we could have written:

form_field = (H, name) ->
  H.p ->
    H.text name
    H.text ' '
    H.input type: 'text', name: name

form = (H, action, fields) ->
  H.form action: action, ->
    for field in fields
      form_field H, field
    H.input type: 'submit', value: 'Submit'

form_html = HtmlMaker.render_external form, 'send.address.com', ['name', 'address']

Note the differences:

• No fat arrows needed (for HtmlMaker's shake, maybe they're needed for other reason)
• No internal render method needed

Data attributes

Data attributes can be defined in a single data object:

card = (name, address) ->
  @div data: { name: name, city: city }, =>
    @text name
console.log HtmlMaker.render card, 'John', 'Springfield'

Result:

<div data-name="John" data-city="Springfield">John</div>

Which is equivalent to:

card = (name, city) ->
  @div 'data-name': name, 'data-city': address, =>
    @text name

Note that data attribute names can use camelCase:

card = (name) ->
  @div data: { personName: name }, =>
    @text name
console.log HtmlMaker.render card, 'John'

And they will be automaticalley dasherized:

<div data-person-name="John">John</div>

Style attributes

Like data, style attributes can be defined with an object (and property names can be camelized as well):

card = (name) ->
  @div name,
    data: { personName: name }
    style:
      textAlign:  'center',
      lineHeight: '100px'
      border:     '10px solid blue'
console.log HtmlMaker.render card, 'John'

The result (formatted for convenience):

<div
  data-person-name="John"
  style="text-align: center; line-height: 100px; border: 10px solid blue">
  John
</div>
