HTML API Render Programmatic Generate Page DOM JavaScript EZHTML

EZ HTML v2.4.2

This Node.js module is designed to be a simple API for programatically rendering HTML 5 web pages. It outputs clean, formatted code, making it easy to troubleshoot errors and verify the rendered output. The module includes classes for each HTML 5 element type and also a Page class that has shorthand methods for each HTML element that can be called sequentially, nesting elements automatically or explicitly by passing an argument to the method, for rapid HTML development.

Installation

npm install ezhtml

Current Status

Fully functional, and code base now reduced by over 65% due to conversion to EZ Objects. All HTML 5 elements and attributes have been implemented except those noted below. There are no known bugs currently, but if found they can be reported by opening an issue against the GitHub repository or by initiating a pull request with the fix.

Note: Screen reader support is not currently within the scope of this library, but could be added fairly easily if needed. Same thing with ruby annotations.

Basic Example - Method 1

const express = require('express');
const ezhtml = require(`ezhtml`);

const app = express();

app.get(`/`, (req, res, next) => {
  /** Create new 'page', automatically includes <html>, <head>, and <body> tags */
  const p = new ezhtml.Page();

  /** Append title element to head element - knows to auto-nest under <head> */
  p.title().text(`My Basic Example`);

  /** Append rank 2 heading to body, knows to auto-nest under last <div> else <body> */
  p.h2().text('My Example EZHTML Page');

  /** Append paragraph to body, knows to auto-nest under last <div> else <body> */
  p.paragraph().addClass('my-class').text('This is the first paragraph of my page.');

  /** Render HTML and send as response */
  res.send(p.render());
});

app.listen(8080, () => {
  console.log(`Web server up and running on port 8080!`);
});

Expected Output

<html>
  <head>
    <title>
      My Basic Example
    </title>
  </head>
  <body>
    <h2>
      My Example EZHTML Page
    </h2>
    <p class='my-class'>
      This is the first paragraph of my page.
    </p>
  </body>
</html>

Basic Example - Method 2

const express = require('express');
const ezhtml = require(`ezhtml`);

const app = express();

app.get(`/`, (req, res, next) => {
  /** Create new HTML element */                           
  const html = new ezhtml.HTML();

  /** Create head element */
  const head = new ezhtml.Head();

  /** Append title element to head element */
  head.append(new ezhtml.Title().text(`My Basic Example`));

  /** Append head element to HTML element */
  html.append(head);

  /** Create body element */
  const body = new ezhtml.Body();

  /** Append body element to HTML element */
  html.append(body);

  /** Append rank 2 heading to body */
  body.append(new ezhtml.H2().text('My Example EZHTML Page'));

  /** Append paragraph to body */
  body.append(new ezhtml.Paragraph().addClass('my-class').text('This is the first paragraph of my page.'));

  /** Render HTML and send as response */
  res.send(html.render());
});

app.listen(8080, () => {
  console.log(`Web server up and running on port 8080!`);
});

Expected Output

Same as Method 1, see above.

Usage

Each HTML 5 element is represented by an ES6 class and is accessible as a property of this module. Each class has getter/setter methods corresponding to the various attributes defined for the element in the HTML 5 standard. In addition, custom attributes can be set and retrieved using the attr(name) getter and attr(name, value) setter. Elements that are 'containers', i.e. they have an open and close tag, also have append() and prepend() methods you can use to add other child elements. Every element has addClass() and removeClass() methods which make the controlling of CSS and DOM selection easy. A full list of elements and their HTML 5 properties is shown below:

The Page Class

The page class contains helper methods to instanciate and automatically or explicitly nest a new EZ HTML element under your page container. See the Method 1 examples above and page.js for more detail about the method names and automatic nesting of each element. More complete documentation will be added soon.

Method Signatures Common to All Elements

Element.addClass(list)

Parameter: list - string
Description: Add the class, or space delimeted list of classes, in list to the element.

Element.attr(name)

Parameter: name - string
Description: Get the value of the attribute named name.

Element.attr(name, value)

Parameter: name - string
Parameter: value - string|number
Description: Set the the attribute named name to value.

Element.id()

Description: Get the value of the element's id attribute.

Element.id(value)

Parameter: value - string|number
Description: Set the the element's id attribute to value.

Element.name()

Description: Get the value of the element's name attribute.

Element.name(value)

Parameter: value - string|number
Description: Set the the element's name attribute to value.

Element.removeClass(class)

Description: class - string
Description: Remove any class named class from the element.

Element.parent()

Description: Get the parent element of this element (or null if none exists).

Element.render([indent])

Parameter: indent - number - (optional) Defaults to zero
Description: Get the rendered HTML of this element and all of its children, prepending all lines with optional indent number of spaces.

Element.tag()

Description: Get the HTML tag of this element.

Method Signatures Common to All Container Elements

This includes all elements that have closing tags, e.g. </element>.

ContainerElement.append(element)

Parameter: element - mixed Any valid EZ HTML element
Description: Append element to the end of this element's array of children.

ContainerElement.prepend(element)

Parameter: element - mixed Any valid EZ HTML element
Description: Prepend element to the beginning of this element's array of children.

ContainerElement.text(content)

Parameter: content - string
Description: A shortcut method for appending plain text content to the end of this element's children array. This is a shortcut for append(new ezhtml.Text().text(content)).

Below are the element classes included in the library along with each of their attributes that will each have a getter of the form property(), and a setter of the form property(value).
